GENERAL FEATURES

The FWECSA controller is designed to control all of the system units in the Daikin range with multi-speed, single-phase motor or coupled to an inverter for speed modulation.

The FWECSA controller system is composed of:

• I/O board containing the power supply circuit, the microprocessor system and the connectors (unscreewable) to connect the input and output devices;
• User unit composed of graphic display and keyboard (six keys) equipped with clock and probe to read the room temperature.

The connection between the I/O board and the user unit is set up using the relative connectors and a data transmission cable fitted with a pair of twisted conductors and shielding.

The controller makes serial communication possible on two types of networks:

• External Supervisor System solution: connection to an external supervision system with MODBUS RTU protocol on serial RS485;

• SMALL solution: connection of multiple FWECSA controllers in two possible configurations:

• MASTER/SLAVE on serial RS485

• MASTER/SLAVE on CW (Conveyed Waves), which can also be set up with External Supervisor System solutions.

- Mixed net solution: connection of multiple FWECSA controllers on different levels :

• MASTER/SLAVE on serial RS485 (external supervisor system or FWECSA), directions to the slaves RS485 (called zone MASTER)
• zone MASTER FWECSA, receiving directions from NET MASTER RS485, transmitting directions to SLAVES OC
• NET SLAVES OC, working exactly to the ZONE MASTER

MAIN FUNCTIONS

• Automatic or manual fan speed variation (selected from the keyboard);
- Management of ON/OFF or modulating valves for two or four-piped systems.
- SUPPORTING electric heater control, used during heating;
- SUMMER/WINTER mode switch (= cooling/heating) in four possible ways:

• manually, from the keyboard;
• manually, remotely (from digital input);
• automatically, depending on water temperature;
• automatically, depending on air temperature.

• dehumidification function control;
• operation with TIME SLOTS.

It is also supplied with:

• External pre-consensus digital input (for example: window contact, remote ON/OFF, presence sensor, etc.) that can enable or disable unit operation (contact logic: see board configuration parameters);
• Digital switching input Remote centralised Cooling/Heating (contact logic: see board configuration parameters);
• Digital input to enable ECONOMY function from remote control (contact logic: see board configuration parameters);
  • Water temperature probe (accessory), one or two (optional with 4-pipe systems);
• STANDARD room air temperature probe (installed inside the user unit);
• Remote room air probe (accessory) that can be used, if connected, in place of the standard one installed in the user interface;
  • Remote relative room air humidity probe (accessory);
  • A completely configurable digital output (dry contact).

• if there is a heater and a valve, then the valve must be a 3-WAY (NO 2-WAY VALVES);
• if Summer/Winter switching is set on "Auto on water temp." then there must also be a water probe;
  • no heater must be installed on 4-pipe units;
• with 4-pipe units with a single water probe, summer/winter switching cannot be set on "Auto on water temp.";
• it is only possible to set summer/winter switching on "Auto on air temp." if there is an electric heater or if the unit has 4-pipes;
• If SUMMER/WINTER switching is set on "Auto on water temp." it is not possible to use a 2-way valve. The water probe must be installed on a point in the hydraulic circuit with minimum circulation.

CONFIGURABLE DIGITAL OUTPUT

The board has a digital output (identified by 07 on the electrical diagram) and its status is linked to one of the operating statuses of the unit reported in the list below:

• Operating mode
  • Cooling or heating request
• Cooling request
• Heating request
  • ON/OFF status of the unit
• Alarm installed
• Dehumidify call
• Humidify call
  • High room temperature
• Low room temperature
  • No water consent to heating
  • No water consent to cooling
• From supervisor

and selectable from the "DOUT Configuration" configuration parameter. It is also possible to choose, using the next "Digital output logic" parameter setting, whether the status of the relay needs to follow the logic NO (Normally Open) or NC (Normally Closed).

STAND-BY MODE

If no operation is performed on the user unit keyboard for 30 seconds the main screen goes into stand-by mode, which can differ based on the settings of the "Stand-by Mode" parameter, accordingly:

• Stand-by mode = Off: the display goes completely black;
• Stand-by mode = Clock: the display goes partly black and the current time and date are shown;
• Stand-by Mode = Temperature: the display goes partly black and the room temperature and any humidity are shown, if the probe is installed.

SERIAL CONNECTION FAILURE

If the serial connection fails with the controller set as SLAVE, FWECSA will either maintain the supervisor on/off settings and summer/winter mode, or it will reset the last settings entered from the keyboard, based on the relative configuration parameter.

The operating mode of the thermostat is indicated on the display by the symbols COOLING and HEATING.

VENTILATION

GENERAL ASPECTS

The control can manage two types of ventilation:

• step ventilation with a set number of selectable speeds (3 or 4);
• modulating ventilation with variable speed between 0% and 100%

The use of one or the other type of control depends on the type of ventilator (step or modulating) installed on-board the machine. Step adjustment itself can follow two different logics based on the type of valve/s (ON/OFF or modulating). In brief, the automatic adjustment logics managed by the controller (and described in detail here below) are as follows:

• step ventilation with ON/OFF valve (or not installed) and 3 speeds, in cooling and heating mode;
• step ventilation with ON/OFF valve (or not installed) and 4 speeds, in summer and winter mode;
• step ventilation with modulating valve and 3 speeds, in summer and winter mode;
• step ventilation with modulating valve and 4 speeds, in summer and winter mode;
• modulating ventilation adjustment with ON/OFF valve, in summer and winter mode;
  • modulating ventilation adjustment with modulating valve.

NATURAL CONVECTION

For units with valve, by enabling the parameter from the configuration menu, ventilation for heating is delayed by 0.5^ C to allow for an initial natural convection phase.

STEP VENTILATION

Use the UP/DOWN keys to choose from the following speeds:

• Automatic SPD.: depending on set temperature and room air temperature;
- Extra-low spd: can only be selected if the unit is 4 speeds
- Low SPEED
• Medium SPD.
• High SPD.

HEATING

MODULATING VENTILATION

As with step ventilation, the management logic for modulating ventilation offers two possible operating modes:

• AUTOMATIC operation
• fixed-speed OPERATION

The operating percentage is selected by pressing the UP/DOWN keys, while automatic ventilation comes on when ventilation is set below the minimum (20%) or above the maximum (100%) values.

HEATING WITH 3-SPEED CONFIGURATIONS

HEATING WITH 4-SPEED CONFIGURATIONS

For configurations with 4 speeds, ventilation for heating is delayed by 0.5°C to allow for an initial natural convection phase.

WATER CONSENT

Regardless of what type of fan is installed (step or modulating), ventilation depends on the system's water temperature control. Depending on the work mode, we will have different consent thresholds for heating and cooling.

COOLING

17.0° 22.0°

HEATING

× 30.0° 37.0°

Failure to have this consent, when the thermostat sends a signal, will be displayed by the flashing symbol of the mode that is currently in operation Cooling or Heating. This enabling signal will be ignored if:

• the water probe is not required or it is in alarm conditions because it is disconnected
  • Cooling with 4-pipe configurations

FORCED OPERATIONS

Normal ventilation logic (modulating and non-modulating) will be ignored in particular forcing situations which could be necessary for the correct temperature control or functioning of the terminal.

Possible situations:

• in COOLING MODE:

• with on-board controller and configurations with valve: the minimum available speed is maintained even when the temperature is reached
• with on-board controller and configurations without valve: every 10 minutes a 2-minute washing at medium speed with the fan stopped allows the air probe to perform a more precise room temperature reading.
• if ventilation is set on standby always ON, the selected speed is maintained once the temperature setpoint is reached.

- in HEATING MODE:

• with the heater on: ventilation is forced at medium speed
• once the heater is switched off: post-ventilation is maintained at medium speed for 2 minutes. (NB: this ventilation will be completed even should the thermostat be turned off or pass to the cooling mode.)
• if ventilation is set on standby always ON, the selected speed is maintained once the temperature setpoint is reached.

VALVE

The control can manage 2- or 3-way ON/OFF (i.e. fully open or fully closed) or modulating valves (valve opening can range between 0% and 100%).

ON/OFF VALVE

Valve (2- or 3-way) opening is controlled depending on the operating setpoint and air temperature setpoint.

COOLING

Off On set set+0,5°

HEATING

On set-0,5° Set Off set

MODULATING VALVE

Valve (2- or 3-way) opening is controlled depending on the operating setpoint and air temperature setpoint. The opening adjustment logic follows the diagrams provided below.

COOLING

HEATING WITH 3-SPEED CONFIGURATIONS

HEATING WITH 4-SPEED CONFIGURATIONS

WATER CONSENT

Water temperature control for opening consent only concerns configurations with 3-way valves and electrical heater. In such configurations the water temperature will be checked in the following cases:

• Heating with heater: heater operation requires forced ventilation; it is therefore necessary to avoid water that is too cold from passing through the unit.

× 25.0° 30.0°

- Post ventilation due to the heater switching off: maintained until the end of the set time, even if the operation mode is changed. During post-ventilation water consent coincides with consent required for ventilation.

ELECTRICAL HEATER

SWITCHING IT ON

If it has been preventively included by the configuration parameter and use is enabled by the setup parameter, the electrical heater is used when the thermostats requires it, based on the room temperature:

On set-0,5° Set Off →

Switching it on entails forced ventilation.

WATER CONSENT

Consent to switch on the heater depends on water temperature control. The following is the relative consent logic:

HEATING

37.0° 39.0°

This enabling signal will not be given if the water probe is not included or is disconnected.

ECONOMY

If it has been preventively included by the configuration parameter and use is enabled by the setup parameter, the Economy function will correct the setpoint by 2.5°C and force operation at the minimum available seed to reduce unit operation.

• Cooling: set + 2.5°C
• Heating: set - 2.5°C

MINIMUM TEMPERATURE CONTROL

If it has been preventively included by the configuration parameter and use is enabled by the setup parameter, when the thermostat is off, this logic avoids the room temperature from dropping below a settable threshold ("Minimum temperature control SET"), forcing the unit to heating mode for the required amount of time.

If the electrical heater is present, it will be used only if it was previously selected as a resource in the Heating mode.

SWITCHING IT ON

If this control is selected, the terminal will turn on if the room temperature falls below 9^ C:

On 9° 10.0° Off

Once the temperature returns above 10^ C, the thermostat will go back Off.

Pressing OFF on the digital input will deactivate this logic.

DEHUMIDIFICATION

The dehumidification function, which can only be used in Cooling mode, if a humidity probe has been included in the configuration menu, makes the unit operate with the aim of reducing any humidity in the room, until it reaches the setpoint level entered in the setup menu parameter.

LOGIC

Ventilation speed will be forced to low, or, if the temperature is much higher than the entered set, to medium speed.

Vmin Set+0.5° Set+1.5° Vmed

They must bring humidity back to the set value (and the valve, if installed), ventilation will switch on even if the room temperature has already reached the relative set (shown on the display). If it drops too far below this threshold, the logic will be temporarily disabled.

Inib. Set-2.0° Set-1.5°

WATER CONSENT

Consent to switch on dehumidification depends on water temperature control. The following is the relative consent logic:

✓ 10.0° × →

If there is no consent the dehumidification function will be momentarily disabled. This will also happen if the probe is disconnected.

Once the reference humidity level is reached or the controller is placed on Off, dehumidification will switch off.

ALARMS

The alarms managed by the controller refer to missing probes required by the unit's configuration. Accordingly, the following are possible alarms:

• Air probe alarm
• Water probe alarm
• Humidity probe alarm

NETWORKS AND CONNECTIVITY

CONNECTION TO SUPERVISION SYSTEM (EXTERNAL SUPERVISOR SYSTEM SOLUTION)

Connection is possible for version External Supervisor System 3.10 or higher.

Using serial port RS485 it is possible to connect FWECSA controllers (up to 247) to a management software that uses standard MODBUS RTU as a communication protocol, with the following characteristics:

• settable baudrate (defualt: 9600);
- no parity
- 8 bits of data
• 1 bit of stops

Inside a supervision network, each FWECSA controller acts as a SLAVE towards the centralised management system which constitutes the network MASTER (figure 01).

Once the network has been wired, it is necessary to configure each FWECSA controller. Press PRG to access the MENU and then enter sub-menu "Networks and connections" (password = 20). Set the SETUP RS485 parameters as follows:

• MST/SLV = "Slave from SPV"
- Protocol = "Modbus"
- Serial address = set a value between 1 and 255
- Speed = set based on the requirements of the Master leave the SETUP OC PARAMETERS UNCHANGED (MST/SLV = none).

For details on how to wire the network, read "RS485 NETWORK GUIDE LINES" available in the download area of the Daikin website.

The following functions are recognised and managed by the

"SMALL" NETWORK SOLUTIONS

"SMALL" network solutions constitute a MASTER/SLAVE network system where one of the FWECSA controllers performs the function of MASTER while all of the other FWECSA controllers on the network perform the SLAVE function.

It can be set up in two different ways, each with different functions and type of connection:

• SMALL network on RS485
• SMALL network on CONVEYED WAVES

SMALL NETWORK ON RS485

In this case the connection is set up using bus RS485, comprised of a twisted 2-conductor, shielded data cable (figure 02).

i

For details on how to wire the network, read "RS485 NETWORK GUIDE LINES" available in the download area of the Daikin website.

The MASTER controller sends the following settings to the SLAVE controller:

• Operating mode: (COOLING or HEATING);
- ON/OFF status of the controller: all of the SLAVE controllers switch to the ON/OFF status of the MASTER controller;
• Enabling minimum room temperature control;
• Room temperature SET;

or (based on the "Temperature control from MASTER" parameter in the "Networks and Connections" menu):

- Limits that apply to changes in the room temperature SET (both SUMMER and WINTER): on each SLAVE controller, the SET variation is allowed with a delta of ±2^ around the value of the SET entered on the MASTER controller.

In terms of the ON/OFF status, the following is allowed on each SLAVE controller:

• Automatic local ON when requested by the minimum room air temperature control function.
• Automatic local ON/OFF depending on the time slots, if enabled;
- OFF on SLAVE controller from digital input if it is enabled.

Each SLAVE controller maintains its autonomy in managing ventilation speed, in switching the ECONOMY function on and in setting the SET value (with the limits described above).

This type of network does not allow a supervision network to be included (External Supervisor System solution) as the RS485 serial ports on all of the controllers (both MASTER and SLAVE) are already occupied by the SMALL network arrangement.

Once the network has been wired, it is necessary to configure each FWECSA controller. Press PRG to access the MENU and then enter sub-menu "Networks and connections" (password = 20). Set the SETUP RS485 parameters as follows:

• MST/SLV = set "Master" on the FWECSA controller acting as the MASTER on the network, and set "Local Slave" on all of the FWECSA controllers acting as the SLAVEs in the network.
• Protocol = "Modbus"
• Serial address = set a value between 1 and 255, only in the SLAVE controllers.
  • Speed = do not change (9600)

Leave the SETUP OC PARAMETERS UNCHANGED (MST/SLV = none).

SMALL NETWORK ON CONVEYED WAVES

This type of configuration controls up to a maximum of 32 hydronic units through a single user unit.

The connection is set up using an OC bus, comprised of a twisted 2-conductor, shielded data cable (figure 03).

In this case, the MASTER controller makes all of the SLAVE controllers connected to the network operate (instant by instant) in an identical fashion to the MASTER controller itself. Accordingly, no SLAVE controller can make autonomous decisions, nor are they equipped with their own user unit.

The maximum number of SLAVE controllers that can be connected to this type of network is 32.

Before connecting the I/O boards to the network, each board needs to be configured.

Connect the user unit to each I/O board.

Press PRG to access the MENU and then enter sub-menu "Networks and connections" (password = 20). Set the OC

SETUP parameters as follows:

• MST/SLV = set "Master" on the I/O board acting as the MASTER of the network and "Slave" on all of the SLAVEs in the network.
• Serial address = set a value between 2 and 34 on the SLAVE controllers.

It is now possible to connect all of the I/O boards to the network.

Once the board has been set as SLAVE, it can no longer communicate with any random user unit. Accordingly, if the settings are changed, it will be necessary to RESET it in the following manner: disconnect the board from the network and, keeping it powered, place digital input 10 in short circuit for 15 seconds (clamps I10 and IC).

All of the hydronic units (i.e. both MASTER and SLAVE) connected to the network must be configured in the same way.

MIXED NETWORK

The SMALL network on CONVEYED WAVES can also be connected to a supervision network (External Supervisor System or SMALL solution) on RS485 through RS485 serial port of the MASTER controller, thus obtaining what is known as a MIXED NETWORK. Figure 04 illustrates the diagram of a mixed network comprised of a SMALL network on CONVEYED WAVES combined with a supervision network.

INSTALLATION AND MAINTENANCE

The procedures for installing the user interface, the power board and probes, with specific instructions for individual hydronic units of the Daikin range, will be described at a later stage.

PROBE INSTALLATION

The FWECSA controller manages the following probes:

• Air temperature reading probe installed inside the user unit; it does not require any special installation operations.
• Probe (optional and alternative to the previous one) connected to the I/O board for temperature readings of the air taken in by the machine, or in any other point of the room subject to temperature adjustment (REMOTE AIR PROBE)
• Probes (optional) for water temperature readings: it is possible to connect one or two probes, depending on whether the unit is connected to a 2- or 4-pipe system.
• Probe (optional) to read the relative ambient humidity, connected to the I/O board

To avoid interference, and subsequent faulty operation, the probe cables must NOT be set up near power cables 8230V).

REMOTE AIR PROBE INSTALLATION

Use of the remote air probe to adjust the room temperature is optional. When it is used, it becomes the main adjustment probe, in place of the probe installed inside the user unit. It is always possible to choose the main room temperature adjustment probe from the "air probe" parameter contained in the CONFIGURATION MENU.

The remote air probe must always be connected to clamps I1-C1 on the I/O board.

Use the supplied adhesive plastic probe-holder:

• Fan coil without base (figure 05)
• Fan coil with base (figure 06)
• Fan coil with front suction (figure 07)

HUMIDITY PROBE INSTALLATION

The humidity probe is an optional accessory. If one is installed, it must be connected to the SU-SU clamps on the I/O board. The probe sensor can be positioned where it will be in contact with the air flow of the unit's suction circuit (if there is also a remote temperature probe, strap them together as illustrated in the figure below) or in any other point in the room subject to temperature and humidity adjustment.

Simple line drawing of a rope knot with two connectors (no text or symbols)

IT IS also possible to position the probe sensor inside the user unit using the relative hook on the base of the unit (figure 08).

The cable supplied with the humidity sensor is equipped with a shield. There is no need to connect this shield to the I/O board. If interference from near-by power cables or other is affecting the relative humidity reading, connect the aforementioned shield to the GND clamp on the RS485 serial port.

WATER PROBE INSTALLATION

The water temperature detection probe (white cable) is an optional accessory.

With 2-pipe units (single coil) the water probe must be connected to clamps I2 - C1 of the I/O board. With 4-pipe units it is possible to choose (through the "Number of water probes" parameter in the CONFIGURATION MENU) how many probes (one or two) to use. If you choose to use a water probe, it must be installed so that it reads the

temperature of the heating water (and is therefore installed on the hot water coil) and must be connected to clamps I2 - C1 of the I/O board. If, on the other hand, you choose to use two water probes, the cold water detection probe must be connected to clamps I2 - C1 of the I/O board, whereas the hot water detection probe must be connected to clamps I3 - C1 of the I/O board.

Use the copper probe-holder for the water probe and, depending on the case, set it up as described below. Fan coils for:

• 2-PIPE system - NO VALVE or 2-WAY VALVE: the water probe must be set up on the exchanger (figure 09);
• 2-PIPE system - NO VALVE or 2-WAY VALVE: the water probe (if single) must be set up on the exchanger in the heating circuit (figure 10); any second probe must be installed on the exchanger in the cooling circuit;
• 2-PIPE system - WITH 3-WAY VALVE: the water probe must be positioned on the valve entrance, on the branch leading out from the system (figure 11);
• 4-PIPE system - WITH 3-WAY VALVES: the water probe (if single) must be positioned on the entrance of the heating valve, on the branch leading out from the circuit (figure 12); any second probe must be installed on the entrance of the cooling valve on the branch leading out from the circuit.

FWD

Example, valves installed on the left side:

Water probe for 4-pipe system AIR Water probe for 2-pipe system AIR

• For FWD units without valves, for 2-pipe systems, the water probe must be positioned on the pipe at the entrance of the exchanger.
• For FWD units without valves, for 4-pipe systems, the water probe must be positioned on the pipe at the

entrance of the exchanger in the heating circuit.

FWB-FWP

Example, valves installed on the left side:

System pipe supplied by the customer

• For FWB-FWP units without valves, for 2-pipe systems, the water probe must be positioned on the pipe at the entrance of the exchanger.
• For FWB-FWP units without valves, for 4-pipe systems, the water probe must be positioned on the pipe at the entrance of the exchanger in the heating circuit.

USER UNIT INSTALLATION

Choose an area to install the controller panel which is easily accessible to set functions and efficient for room temperature detection (at least 1.5 m from the floor). Therefore, avoid:

• direct sunlight exposure;
• direct exposure to hot or cold air currents;
- placing obstacles which impair correct temperature detection (curtains or furniture);
• the constant presence of water vapour (kitchens, etc.):
• covering or recessing the panel into the wall.

For wall installation of the controller, it is advisable to use a recessed 503 electrical contact box behind the controller to house the wires. For installation, follow the instructions below:

• Remove the controller's closing screw (figure 13).
• If a 503 enclosed gang box is used, pass the cables through the slot at the bottom of the controller and use the relative holes for fastening (figure 13).
• Otherwise drill a hole in the wall, for the fastening holes on the base of the controller, where you wish to install the controller. Use the base of the controller as a template to mark the position of the holes. Pass the cables through the slots on the base and fasten it with plugs onto the previously drilled wall (figure 14).

- Connect the clamp to the display board.

- Close the controller back up using the closing screw.

The connection between the panel and the controller and the I/O board must be set up using the 2-clamp connectors for conveyed waves installed on both devices (see electrical diagram). With the I/O board, there are 2 connectors to set up the connection: it makes no difference which connector is used. It is necessary to use a data cable for networks with a pair of twisted conductors and shielding. It is also necessary to connect the shielding conductor to the clamp (-) on the user side and on the I/O board (figure 19).

ON-BOARD I/O BOARD INSTALLATION

FWV, FWL, FWM, FWZ, FWR, FWS, FWD"

• Install the I/O board on FWD-FWB-FWP-FWZ-FWV-FWR-FWL-FWS-FWM units using the relative clamping bracket and the supplied 9.5 mm screws (figure 15-16-17);
• Screw the 3-way terminal board onto the bracket using the supplied 25 mm screws;
  • Install the bracket onto the side of the unit that is opposite the water infeed/outfeed manifolds;
• Set up the electrical connections as illustrated in the electrical diagram (figure 19); use the cable with a 1.5mm^2 section to connect the unit terminal board (CN) to the board.

FWB-FWP

• On the FWB-FWP unit, install the I/O board directly onto the electrical connections box using the supplied 9.5 mm screws (figure 18).
• Set up the electrical connections as illustrated in the electrical diagram (figure 19); use the cable with a 1.5mm^2 section to connect the unit terminal board (CN) to the board.

ELECTRICAL CONNECTIONS

All of the operations must be carried out by qualified staff, in accordance with regulations in force. For any electrical-related procedure, refer to the electrical diagrams supplied with the unit. We also suggest making sure that the characteristics of the electrical network are suitable for the absorption levels reported in the electrical data table.

Before carrying out any operation on electrical parts, make sure the power supply is disconnected. Check that the mains voltage is compatible with the specifications of the unit (voltage, number of phases, frequency) shown on the unit rating plate. The supply voltage must not fluctuate by more than ±5% in relation to the rated value. The electrical connections must be set up according to the electrical diagram attached to the specific unit and with the regulations in force.

MAINTENANCE

Maintenance operations must be carried out exclusively by a manufacturer-authorised assistance centre or by qualified staff. For safety reasons, before carrying out any maintenance or cleaning, turn the equipment off.
