Some information on the use of this manual.

The purpose of this manual is to provide all the necessary information for the use of the controller and relevant software application in the units indicated on the cover.

Information regarding installation of the units and relevant tests and checks for the first starting is not given in this manual.

We thank in advance all those who will wish to let us know of any errors, omissions, sections requiring further explanation or operations that have not been included.

1.1.1 c.pCO controller functions

The software application for the electronic microprocessor controller, series c.pCO, was designed to manage Rooftop units.

Through appropriate configuration, this gives the possibility of managing a wide range of units with relevant specific functionalities.

Management of Rooftop units means monitoring that all component parts operate safely throughout the various operating cycles.

The family of c.pCO electronic microprocessor controllers includes various module sizes. The software is flexible to the extent that the use of modules is optimized, meaning the modules used for reach application are those having the necessary number of inputs and outputs.

The c.pCO board is connected to the various modules and communicates with them via a high speed, highly reliable field bus.

The controller user interface consists in a colour, 4.3" touch-screen display.

2.1 Main functions

The necessary instructions for working on the controller, with regard to the main functions of the unit, are given below.

2.2 Switching the unit on and off

5.1 Introduction

For management of the units, special software is loaded into the controller.

The software consists of a combination of functions dedicated to the conditions in which the units may have to work.

The following chapters describe all the functions managed by the software, ranging from ordinary functions featured in all units to functions dedicated to specific versions or models.

DAIKIN UATYA70BFC3Y1 - Introduction - 1

Some of the functions described here may be available only on specific versions or sizes, or according to the selected accessories.

In describing the various functions, competence in operation of the units and knowledge of the relevant hydraulic or refrigerant circuits are taken for granted. All the descriptions, settings and parameters given refer to units that are correctly installed as described in the relevant documentation.

5.2 Set point management

The control setpoint mainly depends on parameters "ST1" and "STH1".

The relevant settable minimum and maximum setpoint parameters are shown below.

Parameter Min MaxUM Description
ST1 ST2 ST3 ^ Mechanical cooling - Temperature setpoint
STH1 STH2 STH3 ^ Mechanical heating / Auxiliary heating in winter mode - Temperature setpoint

Provision has been made for ancillary functions that are designed to either add or subtract an offset value to/from these setpoints.

DAIKIN UATYA70BFC3Y1 - Set point management - 1

Any automatic variation of the setpoint must be within the corresponding limits.

DAIKIN UATYA70BFC3Y1 - Set point management - 2

Parameter "SD2" is used to set the operating mode in which setpoint variation is enabled. There is only one function available and this is the function enabled at the factory.

5.2.1 Dynamic Set Point

The dynamic set point is a function enabled by the manufacturer.

The reference parameters in managing the dynamic set point are described below.

Parameter Min MaxUM Description
ST1 ST2 ST3°C Mechanical cooling - Temperature setpoint
STH1 STH2 STH3 °CMechanical heating / Auxiliary heating in winter mode - Temperature setpoint
SD202-States of the unit in which it is active
SD100.055.0°CMechanical cooling - External air temperature - Activation threshold for compensation
SD200.055.0°CMechanical heating - External air temperature - Activation threshold for compensation

5.2.2 Dynamic setpoint from external air probe in cooling mode

The setpoint value entered in parameter "ST1" is "compensated" against the external air temperature.

The parameters concerned are shown in the table.

DAIKIN UATYA70BFC3Y1 - Dynamic setpoint from external air probe in cooling mode - 1

The values of the parameters are representative. In specific cases, different values can be set.

Parameter Value UMDescription

A graphical representation is shown below.

DAIKIN UATYA70BFC3Y1 - Dynamic setpoint from external air probe in cooling mode - 2
Fig. 1 Change in setpoint as the air temperature changes in cooling mode

Where "Text" is the value of the external air temperature.

When this function is enabled, the setpoint value that the controller uses to manage the air temperature in cooling mode is as follows:

  • if the external air temperature is lower than the setpoint in parameter "SD10", the value of the control setpoint is the value stored in parameter "ST1";
  • if the external air temperature is higher than the setpoint in parameter "SD10", plus the value in parameter "SD11", the value of the control setpoint is given by the sum of the values stored in parameters "ST1" and "SD12";
  • if the external air temperature is between the values of parameter "SD10" and the sum of the values stored in parameters "SD10" and "SD11", the value of the control setpoint varies proportionally between the value stored in parameter "ST1" and the sum of the values stored in parameters "ST1" and "SD12".

DAIKIN UATYA70BFC3Y1 - Where "Text" is the value of the external air temperature. - 1

Parameter “SD12” can have positive or negative values. When the value is negative, parameter “SD12” has to be subtracted from the value of parameter “ST1”.

5.2.3 Dynamic setpoint from external air probe in heating mode

The setpoint value entered in parameter "STH1" is "compensated" against the external air temperature.

The parameters concerned are shown in the table.

DAIKIN UATYA70BFC3Y1 - Dynamic setpoint from external air probe in heating mode - 1

Fig. 2 Change in setpoint as the air temperature changes in heating mode

Where "Text" is the value of the external air temperature.

When this function is enabled, the setpoint value that the controller uses to manage the air temperature in heating mode is as follows:

  • if the external air temperature is higher than the setpoint in parameter "SD20", the value of the control setpoint is the value stored in parameter "STH1";
  • if the external air temperature is lower than the setpoint in parameter "SD20", minus the value in parameter "SD21", the value of the control setpoint is given by the sum of the values stored in parameters "STH1" and "SD22";
  • if the external air temperature is between the values of parameter "SD20" and the difference of the values stored in parameters "SD20" and "SD21", the value of the control setpoint varies proportionally between the value stored in parameter "STH1" and the sum of the values stored in parameters "STH1" and "SD22".

DAIKIN UATYA70BFC3Y1 - Where "Text" is the value of the external air temperature. - 1

Parameter "SD22" can have positive or negative values. When the value is negative, parameter "SD22" has to be subtracted from the value of parameter "STH1".

5.3 Temperature control

Cooling and heating devices are controlled according to the temperature value measured by a reference probe.

The proportional band identifies the control range of the air conditioner system and it can be set up with independent values for heating and cooling mode.

The dead zone identifies the range around the setpoint within which the devices are not enabled (it is used to prevent oscillations in the setup value).

The values set in parameters "ST9" for cooling and "STH9" for heating determine the control probe type, as follows:

  • 0 = temperature probe on air delivery line;
  • 1 = temperature probe on air return line;

The values set in parameters “ST11” for cooling and “STH11” for heating determine the type of temperature control, as follows:

  • 0 = proportional.
  • 1 = "Cascade";
  • 2 = PID.

5.3.1 Thermoregulation in cooling mode

The thermoregulation of the unit depends on parameter "ST9", which identifies the reference probe for the temperature setpoint (parameter "ST1"), and on parameter "ST11" which determines the type of temperature/humidity control.

In proportional control mode, the controller activates the available resources as the value read by the reference probe increases in comparison to the setpoint value.

When “Cascade” temperature/humidity control is selected, the controller uses it to enable the resources and at the same time monitor the air temperature in the delivery line.

In PID control mode, the controller activates the available resources as the demand increases. The controller calculates the demand and checks the value measured by the probe against the setpoint value and according to its variation over time using the parameters set in the PID.

Proportional temperature control

If parameter "ST11" is set to "0", proportional control is enabled.

The parameters involved in proportional temperature control are shown in the table.

In addition to the parameters listed in the table, the abbreviations in the graph are:

  • Spd = air setpoint in delivery line;
  • Tra = air temperature in return line;
  • AOC = automatic mode switching.

5.3.2 Thermoregulation in heating mode

The thermoregulation of the unit in heating mode depends on parameter "STH9", which identifies the reference probe for the temperature value in the setpoint (parameter "STH1"), and on parameter "STH11" which determines the type of temperature control.

In proportional control mode, the controller activates the available resources as the value read by the reference probe decreases in comparison to the setpoint value.

When “Cascade” control is selected, the controller enables the resources and at the same time monitors the air temperature in the delivery line.

In PID control mode, the controller activates the available resources as the demand increases. The controller calculates the demand and checks the value measured by the probe against the setpoint value and according to its variation over time using the parameters set in the PID.

Proportional temperature control

If parameter "STH11" is set to "0", proportional control is enabled.

The parameters involved are shown in the table.

Temperature monitoring with Cascade control

If parameter "ST11" is set to "1", "Cascade" control is enabled.

This function fulfils the system demand and keeps the air temperature in the delivery line within comfort values.

For this purpose, a virtual setpoint is calculated from the stored setpoint, as corrected with the air temperature in the return line.

In addition to the parameters listed in the table, the abbreviations in the graph are:

  • Spd = air setpoint in delivery line;
  • Tra = air temperature in return line;
  • AOC = automatic mode switching.

If the air temperature in the return line is lower than the difference between the setpoints in parameters "ST42" - "STH46", the value of the air setpoint in the delivery line is increased gradually from the value in parameter "ST42" to the value in parameter "STH49", within the differential set in parameter "STH47".

5.3.3 Disabling heating sources depending on external air temperature

The value of the external air temperature is used as reference to disable the heating sources in the unit. The heating sources are disabled when the temperature is either high or low.

The parameters involved are shown in the table.

DAIKIN UATYA70BFC3Y1 - Disabling heating sources depending on external air temperature - 1

The values of the parameters are representative. In specific cases, different values can be set.

Parameter Value UM Description

STH14 -20.0 °C Mechanical heating - Deactivation threshold for low external air temperature
STH15 30.0 °C Mechanical heating - Deactivation threshold for high external air temperature
STH123 -30.0 °C Auxiliary heating - Deactivation threshold for low external air temperature
STH124 50.0 °C Auxiliary heating - Deactivation threshold for high external air temperature

Heating generated using the refrigerant circuit is disabled when:

  • the external air temperature is low - it drops below the setpoint in parameter "STH14"; heating is enabled again when the temperature value rises above the setpoint in parameter "STH14", plus +1°C;
  • the external air temperature is high - it rises above the setpoint in parameter "STH15"; heating is enabled again when the temperature value drops below the setpoint in parameter "STH15", minus +1°C.

Auxiliary heating is disabled when:

  • the external air temperature is low - it drops below the setpoint in parameter "STH123".Auxiliary heating is enabled again when the temperature value rises above the setpoint in parameter "STH123", plus +1°C;
  • the external air temperature is high - it rises above the setpoint in parameter "STH124". Auxiliary heating is enabled again when the temperature value drops below the setpoint in parameter "STH124", minus +1°C.

5.4 humidity control

Humidity control devices are managed according to the value measured by the reference probe. The measured value is compared with the desired value (setpoint), after which the system calculates the difference between these values and then enables the most suitable devices based on this difference.

The proportional band identifies the control range of the air conditioner system and it is set up with the same values for both humidification and de-humidification.

The dead zone identifies the range around the setpoint within which the devices are not enabled (it is used to prevent oscillations in the setup value).

The diagram below shows the behaviour of humidification and de-humidification devices.

5.5 Air humidification

The controller can manage air humidification using a built-in humidifier in the unit.

The controller is set up at the factory with all the parameters required to control the installed humidifier.

5.5.1 Ancillary built-in humidifier functions

Humidifier control includes some ancillary functions, a description of which is given below.

5.5.1.1 Manual water drain

The manual water drain function is designed to fully empty the cylinder in the humidifier. This function is enabled only through the web page. Access to this page requires the operator to log in with a Service level password. If the humidifier is producing steam, enabling of the function causes steam production to be stopped instantly.

5.5.1.2 Pre-washing

The pre-washing function is used to wash the water lines and the humidifier cylinder. The cylinder is filled and then emptied 3 times in order to wash away impurities from the pipes and cylinder, if any. We recommend enabling this function especially after connecting the water lines or after cylinder replacement. This function is enabled only through the web page. Access to this page requires the operator to log in with a Service level password. If the humidifier is producing steam, enabling of the function causes steam production to be stopped instantly.

5.5.1.3 Water drainage before machine shutdown

The function for water drainage before a machine shutdown is enabled in order to avoid water stagnation in the humidifier cylinder, which may lead to the formation of algae or bacteria (e.g. Legionella), if the cylinder is filled with water for over 72 consecutive hours without producing steam. The cylinder is drained and remains as such until it receives a signal requesting the production of steam. The function is always active and the shutdown interval is fixed.

5.6 Air dehumidification

Air dehumidification is required during the cooling cycle, where it occurs naturally.

If dehumidification is required simultaneously with cooling, the controller starts the compressors, based on which of the two demands is greater.

The possibility exists that the temperature setpoint is reached before the humidity setpoint is achieved. If this is the case, the controller pushes cooling even further so as to cause the temperature to drop below the setpoint.

However, to prevent an excessive drop of the air temperature in the room, the controller uses the heating devices fitted in the unit to post-heat the air.

5.7 Power supply control

Units may be supplied with devices for protection against incorrect connections of the phase sequence or voltage variations outside the required limits during operation.

Protections consist in relays which output an alarm signal to one digital input in the controller through an electric contact (the digital input concerned is shown in the wiring diagram).

The unit can be fitted with one relay to monitor correct phase sequence or one relay to monitor the power voltage or one relay to manage both these functions.

5.7.1 Phase sequence

A dedicated relay is fitted to manage incorrect connection of the phase sequence to the unit. If the phase sequence is connected incorrectly, the relay opens an electric contact that triggers alarm "AL55" on the controller display.

Incorrect connection of the phase sequence may be experienced upon unit installation or when work is performed on the power supply line.

Power must be cut out to the unit to make the connection correctly. The alarm is cleared as soon as the unit is switched on again.

5.7.2 Min. / Max. voltage

The controller is designed to manage potential conditions where the variation of the power voltage to the unit experiences a significant deviation from the expected values.

5.7.3 Fast Restart

Activation of the “Fast Restart” function, provided that an “ultracap” is fitted to keep the controller electrically powered, is designed to minimise as much as possible the delay experienced in restarting the compressors fitted in the unit.

This is possible because the controller starts counting the minimum time to OFF as soon as a switch-off is started due to a blackout.

The controller detects problems with the main power supply through a digital input and manages them as alarms.

To protect the integrity of the compressors, the controller manages the maximum number of starts per hour by means of the delay between two consecutive starts.

Quick restart after a blackout depends on the thermoregulation demand. It requires a demand for cooling or dehumidification and the off-set for the activation of at least one compressor.

The “Fast Restart” function does not jeopardise the conditions of the compressors as it limits the number of quick starts over the space of an hour or a day.

5.8 Damper management

In addition to air change in the room, the controller can also manage other functions connected to comfort enhancement and system economy.

The functions the controller can handle vary according to the number of dampers fitted in the unit:

  • units with 2 dampers, for fresh air only;
  • units with 3 dampers, when free cooling / free heating is featured;
  • units with 4 dampers, when a heat recovery system is fitted in addition to free cooling / free heating.

Dampers can be set either linearly or proportionally.

Units with two dampers

The dampers featured in 2-damper units include: a damper for fresh external air and a damper for recirculated air. Normally, their operation is complementary, i.e. the percentage opening of the external air damper is equal to the percentage closing of the recycled air damper.

Units with three dampers

The dampers featured in 3-damper units include: a damper for fresh air, a damper for exhaust air and a damper for recirculated air.

Normally, the external air damper opens at the same percentage as the exhaust air damper and the recycled air damper is complementary to the other two. So, the percentage opening of the external air damper and the exhaust air damper is equal to the percentage closing of the recycled air damper.

Units with four dampers

Units with four dampers feature the same dampers as 3-damper units plus one. The fourth damper is used for external air.

It is used to cause the external air to flow through the heat recovery system, when heat recovery is enabled, and it is closed in free cooling mode.

If the heat recovery system is not sized to provide for a 100% air flow in the unit, a fifth damper is actually fitted. This is an extra exhaust damper that is used by the unit in free cooling mode to bypass the heat recovery system.

The parameters involved are shown in the table.

Parameter Min MaxUM Description
DA43 0.0 50.0°CExternal air - Opening reduction for external air temperature - Summer temperature threshold
DA44 -20.0 160 °CExternal air - Opening reduction for external air temperature - Winter temperature threshold
DA45 0 100 %External air - Opening reduction for external air temperature - Min opening
DA52 0 3 -External air - Start up - Configuration
DA54 0 999 minExternal air - Start up - Wash duration

5.8.1 Damper control

The controller can control the dampers in two different ways: "standard" and "adaptive".

When dampers are required to stay in a fixed position, for instance to provide for the correct flow of fresh air, system conditions may exist in which the damper signal cannot guarantee the desired air percentage.

5.8.1.1 Standard control

Standard control requires that the dampers stay in their position irrespective of the actual fresh air percentage.

5.8.1.2 Adaptive control

Adaptive control corrects damper opening based on the necessary fresh air percentage. This control requires that the mixed air probe is fitted.

The controller uses the values of the air temperature in the return line, the external air temperature and the corresponding damper opening percentage to calculate the theoretical value of mixed air.

The controller compares the calculated mixed air value with the value actually measured and then uses a PID to correct the damper signal until the difference is cancelled.

5.8.2 Damper management

The controller can manage damper control either linearly or proportionally.

Linear control enables opening of the damper with a tilt angle that is equal to the required opening percentage.

Proportional control is designed to open the dampers so that the air can flow, i.e. at the required percentage of the max. possible opening.

DAIKIN UATYA70BFC3Y1 - Damper management - 1

All units featuring dampers are set by default to run a proportional control.

5.8.3 Unit start-up

When the unit is started up, specific damper adjustments may be required for some management functions.

If no washing or recycling cycle is to be run at unit start-up, the controller opens the dampers at the percentage value set for air changing, irrespective of their number.

5.8.4 Washing

Washing means changing the air in the room and it consists in exhausting all the air in the return line and only letting external air flow into the room.

If washing is required at unit start-up, parameter "DA52" must be set to "1".

While the washing cycle is in progress, the controller keeps the exhaust air and external air dampers open at their max. opening percentage and it keeps the recycled air damper in closed position for the time setpoint in parameter "DA54".

If the value in parameter “DA53” is set to “0”, the washing cycle takes place without any thermoregulation of the air. If the value in parameter “DA53” is set to “1”, thermoregulation is active.

If the washing cycle is run with thermoregulation active, the position of the dampers may be affected by conditions resulting from compressor operation.

While the washing cycle is in progress, a button flashes on the main screen: it is pressed to stop the cycle manually before the time set in parameter "DA54" elapses.

5.8.5 Recirculation

Full air recycling at system start-up or after a washing cycle is intended to achieve the temperature and humidity setpoints more quickly.

If air recycling only is required at unit start-up, parameter "DA52" must be set to "2".

If parameter "DA52" is set to "3", a washing cycle is performed before recycling.

While recycling is in progress, the controller keeps the exhaust air and external air dampers closed and it keeps the recycled air damper open for the time setpoint stored in parameter "DA55".

If the value in parameter “DA53” is set to “0”, the washing cycle takes place without any thermoregulation of the air. If the value in parameter “DA53” is set to “1”, thermoregulation is active.

While recycling is in progress, a button flashes on the main screen which is pressed to stop the cycle manually before the time set in parameter "DA55" elapses.

5.9 Auxiliary heating

In addition to the heating effect achieved using the refrigerant circuit, the controller can handle other sources of heating such as electric heaters and a hot water coil with an OK signal to a boiler or a burner.

The logic featured in the controller is set up at the factory, based on the unit configuration.

The function to enable heating and the operating logics can be customised.

The parameters concerned are shown in the table.

STH95 0 100 % Auxiliary heating - Winter oper. - Proportional - Minimum request
STH96 0 100 % Auxiliary heating - Winter oper. - Proportional - Maximum request

5.9.1 Controlled devices

The controller controls the devices installed in the unit, which may include:

  • electrical heaters, divided by either one or two power steps;
  • a hot water coil, with an analogue signal to control opening of a valve and a digital OK signal to control a pump that gets started as soon as the valve opens. This management logic includes the anti-freeze function;
  • a boiler that is controlled by an analogue signal and a digital OK signal which gets enabled as soon as an analogue demand is received. This management logic includes a digital input through which the controller receives alarms from the boiler, if any, as well as an anti-freeze function;
  • a burner that is controlled by an analogue signal and a digital OK signal which gets enabled as soon as an analogue demand is received. This management logic includes a digital input through which the controller receives alarms from the burner, if any.

Parameter "STH55" is used to enable auxiliary heating for:

  • summer operation only, in which case it serves as post heating during the dehumidification cycle;
  • winter operation only, in which case it serves either as single source, if the refrigerant circuit does not feature cycle reversal, or as an integration to heating where the latter is implemented by the refrigerant circuit;
  • both summer and winter operation.

Anti-freeze function

The anti-freeze function, which is included in versions featuring a hot water coil and a boiler, is enabled when the unit is in operation, no heating demand is present and the external air temperature is lower than the setpoint in parameter "STH136".

In versions with a hot water coil, when the anti-freeze function gets enabled, the controller opens the relevant control valve at the value set in parameter "STH137" and it enables the circulation pump.

In versions with a boiler, when the anti-freeze function gets enabled, the controller outputs to the boiler the demand signal as set in parameter "STH137" and an OK signal for activation.

5.9.2 Post heating

When the value in parameter "STH55" is "1", auxiliary heating is configured for summer operation only and serves as post heating during dehumidification. The control can either be proportional or PID, depending on the value set in parameter "STH57". The value in parameter "STH56" identifies the probe taken as reference for the control which is performed according to parameter "STH58".

5.9.3 Activation according to time bands

The unit may be managed automatically according to time bands. The time band management logic is designed to stop the unit, to edit the setpoint and to switch among operating modes.

The parameters concerned are shown in the table.

Parameter Min MaxUM Description

ES34 0 15 - Heating mode activation - Thursday
ES35 0 15 - Heating mode activation - Friday
ES36 0 15 - Heating mode activation - Saturday
ES37 0 15 - Heating mode activation - Sunday

The pairs of start and end parameters are used to set as many as 4 time bands.

Each day of the week can be matched with a combination of the set time bands in order to edit the setpoint, switch the unit off and switch between operating modes.

The setpoint is edited within the selected time band by way of applying an offset to the active operating value.

The active operating value is given by the value set in the relevant parameter and external offsets, if any.

The offset value can be either positive or negative. When it is positive, it is added; when it is negative, it is subtracted.

Two offset values can be set: one for operation in cooling mode and one in heating mode.

DAIKIN UATYA70BFC3Y1 - Activation according to time bands - 1

If the controller manages auxiliary heating, the setpoint in parameter "STH58" is maintained when the time bands are activated in cooling mode; when they are activated in heating mode, the setpoint varies according to the offset value.

5.1 Introduction

The controller is programmed to manage the components of the unit safely, by adjusting their operation as conditions change with the aim of maintaining uninterrupted service.

Within the scope of this control function, the controller will partially or completely limit operation of the unit when hazardous conditions are approaching.

DAIKIN UATYA70BFC3Y1 - Introduction - 1

A click on this icon gives access to the Alarms menu. If the icon is red, at least one alarm is active; no alarm is active if it is grey.

The codes with their descriptions for the various conditions that can appear in the alarm menu are given in the next chapter.

If you notice there are error messages with the unit running and with it stopped, you should promptly inform the customer support centre and given them the code and the message description and wait for their instructions.

The chart displays a stepwise increasing trend in the Y-axis values as the X-axis values are shifted from left to right. The Y-axis values are labeled as percentages (e.g., %). The X-axis values are annotated with 'HU' and 'HU' labels at the start and end points respectively. The chart is divided into two sections: left for HU/HSU ratio ranges (e.g., HU4/HU9, HU5/HU10) and right for HSU/HSU ratio ranges (e.g., HU1/HU6, HU4/HU9). The data series includes a separate series labeled 'SdR %-g/kg'.
