VENTILATION WATER CONTROL The controller can govern 3 or 4-fan speed indoor units

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

OPERATING SPEED SELECTION Using Fan speeds:

key it is possible to select the following

■ AUTO Automatic fan speed: depending on the set temperature and the room air temperature.

With 3-speed configurations: where: 1 = low speed 2 = medium speed 3 = maximum speed

HEATING 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

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

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

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:

COOLING NB: in case of 4-speed configuration and valve, or 3-speed configuration + CN (natural convection), ventilation in heating mode is shifted by 0.5°C to permit a natural convection phase

■ NO SYMBOLS Speed disabled. Can be selected only in heating mode and with 4-speed configuration or 3-speed configuration + CN (natural convection) only. The indoor unit operates by natural convection only. ■

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: after every 10 minutes in which the fan remains idle a 2 minute cleaning is carried out at medium speed to enable the air sensor to read the room temperature more correctly. In the heating mode ■ While the heating element is on: the fan is forced to run at medium speed ■ Once the heating element has gone off: a 2 minute postventilation cycle will be run at medium speed. (NB: this cycle will be completed even if the thermostat is switched off or in the event of a changeover to the cooling mode). DISPLAY The display shows the fan status ■ Stb: fan in standby mode ■ On: fan on ■ noF: 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.

Low speed Medium speed High speed

NB In the case of fixed speed, the fan on/off logic will be equivalent to the automatic logic.

Standard electronic controller FC66002763

Installation and operation manual

The display shows fan speed (with indication of “automatic” logic if proper) enabled or selected (in case of stand-by fan)

HEATING ELEMENT The electrical heating element is a device used to provide support where necessary in the heating mode.

SELECTION If provided for in the configuration, the heating element can be

selected in the heating mode by pressing the Sel

ACTIVATION NB: if the active speed is different from the one selected by the user (in the case of a forced override), pressing the button once will cause the latter to be displayed; pressing again will change this setting.

VALVE The controller can govern 2 or 3-way On/OFF type valves with actuator featuring 230 V.

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

COOLING If use of the heating element is selected by the user, it will be activated on a call from the thermostat based on the room temperature

NB: switching it on will force the fan on as well

WATER CONTROL HEATING ON 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 heating element. In such configurations the water temperature will be checked in the following cases:

Enabling of the heating element 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 DISPLAY The display will show the following information ■ heating element selected by the user: steadily lit symbol ■ active heating element: flashing symbol

■ Heating with heat element: operation of the heating element will force the fan to switch on; it is therefore necessary to prevent excessively cold water from passing through the unit.

■ Post-ventilation due to switching off of the heating element: 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

Installation and operation manual

Standard electronic controller FC66002763

ECONOMY ALARMS 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.

This control governs 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

■ Cooling: setpoint + 2.5°C

■ Heating: setpoint – 2.5°C SERIOUS ALARMS ACTIVATION This function can be activated by pressing the key

DISPLAY The Economy function is shown on the display by the symbol

■ Code 01 = error of external air temperature sensor (in case of on-board thermostat)

■ Code 02 = error of internal air temperature sensor (in case of wall mounted thermostat and disconnected external air temperature sensor)

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 heating element 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.

■ Code 03 = water sensor error

NB: the alarm code is displayed only when the thermostat is switched off.

SELF-DIAGNOSIS PROCEDURE This procedure allows you to check whether the individual outputs of the controller function correctly.

To run the procedure, follow the directions below.

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

NB: Any Off command from digital input will disable this logic DISPLAY The display shows the following information

■ Switch the thermostat off
