GENERAL CHARACTERISTICS LCD DISPLAY (SEE FIGURE 2)

LCD controller has been designed to manage the operation of indoor units with single-phase multispeed asynchronous motor.

Compared to the standard model it has the added features of advanced humidity control and serial communication. This controller allows to set (figure 1) up a Master-Slave system (up to 247 slave terminals), in which one of the Microprocessor controllers plays the role of Master and controls all of the other slave elements. In this case as well the connection is made via an RS485 bus, consisting of a simple shielded 2-conductor cable.

fan status. When flashing it indicates that fans are off standing for a call from the thermostat. If the symbol is steadily lit it means that the fans are running

fan status. Fans are off as speed is set to Off or the control is off.

The master (identified by the address 255) sends the following information to the slave controllers:

(1) Operating mode (Cooling or Heating) (2) Setpoint for room temperature.

AUTO The speed selector of each slave controller remains enabled and the room temperature can be adjusted within a range of

± 2°C around the setpoint value transmitted by the master controller.

MAIN FUNCTIONS AND FEATURES:

■ Air temperature adjustment through automatic variation of fan speed; ■ Regulation of air temperature via fan on-off control (fan runs at a fixed speed), ■ Control of On-Off valves for two or four-pipe systems ■ Control of electrical heater for auxiliary heating. ■ Cooling/heating switching in the following modes: - local manual switching - remote, manual (centralised); - automatic, depending on water temperature - automatic, depending on air temperature ■ Dehumidify Function ■ Serial Communication ADDITIONAL FEATURES INCLUDE: ■ no-voltage contact for external activation (e.g. window contact, remote ON/OFF, occupancy sensor, etc.) which may enable or disable unit operation (contact logic: see circuit board configuration parameters). ■ no-voltage contact for centralised remote Cooling/Heating changeover (contact logic: see circuit board configuration parameters). ■ no-voltage contact for remote enabling of the economy mode (contact logic: see circuit board configuration parameters). ■ remote water temperature probe (accessory FWTSKAA) ■ built-in temperature probe ■ built-in humidity probe ■ remote air temperature probe (accessory FWTSKAA) (this probe, if present, is used in place of the internal one for the measurement of room temperature). ■ Remote humidity probe (accessory FWHSKAA - to be used in combination with the remote temperature probe) The control panel is composed of: ■ LCD display ■ key board

Four logics are present to select the thermostat operating modes according to the controller configuration setting:

Valve: NO Electrical heater: YES Fan speed: 4

Summer/winter switching logic: LOCAL MANUAL SERIAL COMMUNICATION Connection to the RS485 communication network

The communication network (bus type) relies on a simple shielded 2-conductor cable, directly connected to the RS485 serial ports of the controllers (terminals A, B and GND). “For the network use a cable AWG 24 (diam. 0.511 mm)” The communication network must have the following general structure (figure 4). In the case of the “MASTER-SLAVE” solution a termination resistor will have to be installed on both controllers at the furthest ends of the network. N.B.: (1) Comply with the polarity of the connection: indicated with A(-) and B(+) (2) Ground shield at one end only ____________________________________________________________

Use a shielded cable AWG24

Colours suggested for the communication network: A (-) Brown ; B (+) Yellow

____________________________________________________________

N.B.: in case of water sensor alarm, the controller returns to the Local mode temporarily.

With 4-speed configurations where: sm = extra-low speed

1 = low speed 2 = medium speed 3 = maximum speed

FORCED OVERRIDES The normal fan operating logic will be ignored in particular override situations that may be necessary to ensure correct control of the temperature or the unit’s operation. This may occur:

in the cooling mode:

■ on-board controller (P01 = 0) and configurations with valve: the minimum speed available will be maintained even once the temperature has been reached. ■ on-board controller and valveless configurations: every 10 minutes in which the fan remains idle a 2 minute fan rotation is carried out at medium speed to enable the air sensor to read the room temperature more accurately. In the heating mode ■ while the electrical heater is on: the fan is forced to run at medium speed ■ once the electrical heater has gone off: a 2 minute postventilation cycle will be run at medium speed. (N.B.: this cycle will be completed even if the thermostat is switched off or in the event of a changeover to the cooling mode)

N.B.: in case of 4-speed configuration and valve, ventilation in heating mode is shifted by 0.5°C to permit a natural convection phase

■ Speed disabled: Can be selected only in heating mode and with 4-speed configuration only. The indoor unit operates by natural convection only.

■ On flashing: fan in standby mode

■ On steadily lit: fan on ■ OFF: fan disabled to operate by natural convection only

Extra low speed: can be selected only with

4-speed configuration. It works at extra low speed only.

N.B.: In the case of fixed speed, the fan on/off logic will be equivalent to the automatic logic. and fan speed (with indication of “automatic” logic if proper) enabled or selected (in case of stand-by fan)

WATER CONTROL The ventilation operation depends on the system water temperature control. Based on the operation mode, different heating or cooling thresholds will be enabled.

Low speed Medium speed High speed

HEATING NO Water temp.

Upon a call of the thermostat, the absence of the enabling signal will be indicated on the display by the flashing of the symbol representing the active mode (

The enabling signal is ignored:

■ if the water sensor is not included (P04 = 0) or in alarm status because disconnected ■ in the cooling mode with 4-pipe configurations

N.B.: if the active speed is different from the one selected by the user (in the case of a forced override), pressing the button

Fan the selected speed will be displayed;

pressing again will change this setting.

Advanced electronic controller FC66002764

VALVE The controller can manage 2 or 3-way On/OFF type valves, with 230V voltage.

OPENING The valve opening is controlled according to the operating setpoint and air temperature setpoint

COOLING If the electrical heater is selected by the user, it will be activated on a call from the thermostat based on the room temperature

N.B.: switching it on will force the fan on as well WATER CONTROL Enabling of the electrical heater is tied to the water temperature. The related enabling logic is described below The enabling signal will not be given if the water sensor is either not present or disconnected

ON OFF HEATING Air temp.

WATER CONTROL The checking of water temperature to enable valve opening is a function that concerns only configurations with 3-way valves and electrical heater.

In such configurations the water temperature will be checked in the following cases: ■ Heating with electrical heater: operation of the electrical heater will force the fan to switch on; it is therefore necessary to prevent excessively cold water from passing through the unit.

DISPLAY The display will show the following information

■ electrical heater selected by the user: steadily symbol ■ active electrical heater: flashing symbol

ECONOMY The Economy function corrects the setpoint by 2.5°C and forces the fan to run at the minimum available speed to reduce unit operation.

■ Cooling: setpoint + 2.5°C ■ Heating: setpoint -2.5°C ACTIVATION This function can be activated by pressing the key DISPLAY The Economy function is shown

■ Post-ventilation due to switching off of the electrical heater: this function will be maintained until the set time has elapsed, even if the operating mode is changed.

During post-ventilation the water temperature enabling signal will coincide with the one seen for fan operation. DISPLAY The active valve indication on the display will be shown by the symbol

ELECTRICAL HEATER The electrical heater is a device used where necessary in the heating mode.

on the display by the symbol

MINIMUM TEMPERATURE CONTROL This logic makes it possible to keep the room temperature from falling too far when the thermostat is off by forcing the unit into the heating mode if necessary and for the time required.

If the electrical heater is present, it will be used only if it was previously selected as a resource in the heating mode. SELECTION When the thermostat is off, you can select the minimum temperature control by pressing at the same time the keys . The same key combination disables this function. ACTIVATION If this control is selected, the unit will switch on when the room temperature falls below 9°C.

Installation and operation manual

When temperature exceeds 10°C the thermostat will resume the Off status.

N.B.: Any Off command from digital input will disable this logic

WATER CONTROL Enabling of the dehumidification function is tied to the water temperature. The related enabling logic is described below

DISPLAY The display shows the following information

■ Minimum temperature control selected: symbol

■ Minimum temperature control enabled: DEFR If enabling conditions do not exist, the dehumidification function will be temporarily inhibited. The same will occur in the event that the probe is disconnected. N.B.: once the target level of humidity is reached or the controller is switched off, the dehumidify option will be unselected DISPLAY The display shows the following information:

DEHUMIDIFICATION The dehumidification function, enabled only in the cooling mode, activates operation of the indoor unit in order to achieve a 10% reduction in the level of humidity present in the room at the time the function itself was selected.

■ Dehumidification ON: symbol lit

SELECTION Dehumidification can be selected/unselected in the Cooling mode by simultaneously pressing the buttons. If the water probe (P04=0) or the remote humidity probe is not available, in cases where the controller is installed directly on the unit (P08=0), selection will not be enabled. If selected, the dead band for automatic switching on the air side will be brought to 5°

LOGIC Once selected, the dehumidification logic sets the target humidity level as the humidity present at the time the function was selected minus 10%. Where the room humidity is less than 40% the target level will be set at 30%. The fan will be forced to run at low speed or, if the temperature is much higher than the setpoint, at medium speed. Med. speed

■ Dehumidification temporarily inhibited: flashing symbol

ALARMS This control manages two types of alarms:

■ Serious Alarms: cause the forced switching off of the thermostat ■ Non-serious Alarms: do not cause the forced switching off of the thermostat, but disable possible critical functions

SERIOUS ALARMS Min. speed

In order to bring the humidity to the set value, the fan (and valve, if present) will be activated even if the room temperature has already reached the programmed setpoint (indicated on the display by the symbol 3). Should the room temperature fall too far below this threshold, the logic will be temporarily inhibited.
