CONTENTS

1 - OPERATION• LCD controller has been designed to govern the operation of

TWN units 9ith single-phase multispeed asynchronousmotor. In relation to the basic version, the MEDIUM versionsare equipped 9ith advanced humidity management and serialcommunication for a “Master / Slave” system.

• The MEDIUM version can be configured for “Master / Slave”operation (up to 247 secondary interior units). In this case,one of the microprocessor commands performs the “Master”function and as such controls all the other Secondaryelements.

• In this case as 9ell the connection is made via an RS485 bus,consisting of a simple shielded 2-conductor cable.

• The “Master” control (identified by address 255) transmits thefollo9ing information to the “Slave” commands:(1) Operating mode (Cooling or Heating).(2) Setpoint for room temperature.

• The speed selector of each “Slave” controller remains enabled and the room temperature can be adjusted 9ithin a range of P 2°C around the setpoint value transmitted by the “Master” controller.

12 - VENTILATION12.1 - OPERATING SPEED SELECTION

• Using Yey it is possible to select the follo9ing speeds:- AUTO Automatic fan speed: depending on the set temperature and the room air temperature.- 1 = lo9 speed.- 2 = medium speed.- 3 = maximum speed.

• Note:In the case of fixed speed, the fan on/off logic 9ill be equivalent to the automatic logic.

12.2 - ACTIVATION ACCORDING TO THE WATER TEMPERATURE (if sensor connected)• Fan operation may be connected to the installationls 9ater temperature control. Based on the operation mode, different

heating or cooling thresholds 9ill be enabled.

• The absence of this condition 9hen queried by the thermostat 9ill cause the symbol of the mode currently active ( or) to flash.

The enabling signal is ignored:- Water sensor not provided (P04 = 0) or in alarm status.- In the cooling mode 9ith 4-pipe configurations.

12.3 - VENTILATION FORCING• The fan operating logic 9ill 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 9ith valve: the minimum speed 9ill be maintained even once the

temperature has been reached.- On-board controller and valveless configurations: every 10 minutes 9hen the fan is stopped, the ventilation operates for

2 minutes at medium speed to allo9 the air sensor to taYe a more precise reading of the ambient temperature.

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 post-ventilation cycle 9ill be run at medium speed. (Note: ventilation

is time delayed even if the thermostat is set to mOffm or if s9itched to cooling mode).

12.4 - DISPLAY• The display sho9s the fan status:

- ON flashing: fan in standby mode.- ON steady: fan on.- OFF: fan deactivated.

and fan speed (9ith indication of “automatic” logic if proper) enabled or selected:- 1 = Lo9 speed.- 2 = Medium speed.- 3 = High speed.

• Note:if the active speed is different from the one selected by the user (in the case of a forcedoverride), pressing the button once 9ill cause the latter to be displayed; pressing again 9illchange this setting.

13 - “ON/OFF” VALVE• The controller is able to manage the “ON/OFF” type 3-9ay valves, 9ith the valve being supplied at 230V/1/50.

13.1 - VALVE ACTIVATION ACCORDING TO AIR TEMPERATURE• The opening of the valve is controlled according to the setpoint and the ambient air temperature.

13.2 - VALVE ACTIVATION ACCORDING TO WATER TEMPERATURE• Monitoring of the 9ater temperature to activate opening is possible only in configurations 9ith Cold valve and an electric

heater element. In such configurations the 9ater temperature 9ill be checYed in the follo9ing cases: - Heating 9ith heat element: operation of the heating

element 9ill force the fan to s9itch on; it is thereforenecessary to prevent excessively cold 9ater frompassing through the unit.

- Post-ventilation due to s9itching off of the heatingelement: this function 9ill be maintained until the set timehas elapsed, even if the operating mode is changed.

13.3 - DISPLAY• The active valve indication on the display 9ill be sho9n by the symbol .

14 - HEATING ELEMENT• The electric heater element ensures the main heating function in the 2-pipe Cooling + heating element configuration.

Note: The presence of the 9ater sensor is compulsory for this operation.

14.1 - SELECTION• If provided for in the configuration, the heating element can be selected in the heating mode by pressing the Yey.

14.2 - ACTIVATION ACCORDING TO THE AMBIENT TEMPERATURE• If use of the heating element is selected by the user, it 9ill be

activated on a call from the thermostat based on the roomtemperature.

• Note: The activation involves forced ventilation at medium speed.

14.3 - DISPLAY• The display 9ill sho9 the follo9ing information:

15 - “ECO” MODE• The “ECO” mode foresees a correction of the setpoint by 2.5 °C and forcing of the fan at minimum speed to reduce the unitls

operation.• Cooling: setpoint + 2.5°C.• Heating: setpoint – 2.5°C.

15.1 - ACTIVATION• The “ECO” mode is activated by the Yey.• Proceed in the same manner to deactivate the “ECO” mode.

15.2 - DISPLAY• On the monitor, the “ECO” mode is activated: symbol .

16 - “FROST PROTECTION” MODE• With the thermostat being “OFF”, this logic prevents the ambient temperature from dropping too lo9; the unit is thus forced into

heating mode.If the electric heating is present, it 9ill be used only if it had been previously selected.

16.1 - SELECTION• To select the “Frost Protection” mode, 9ith the thermostat set to “OFF”, simultaneously press the Yeys .• The same Yey combination disables this function.

16.2 - ACTIVATION• If this control is selected, the unit 9ill s9itch on 9hen the room

temperature falls belo9 9°C.• When temperature exceeds 10°C the thermostat 9ill resume the

OFF status.• Note:

Any OFF command from digital input 9ill disable this logic.

16.3 - DISPLAY• The display sho9s the follo9ing information:

17 - DEHUMIDIFICATION• The dehumidification function, enabled only in the cooling mode, activates operation of the indoor unit in order to achieve a 10n

reduction in the level of humidity present in the room at the time the function itself 9as selected.

17.1 - SELECTION• Dehumidification can be selected / unselected in the Cooling mode by simultaneously pressing the buttons.• In the absence of a 9ater sensor (P04 = 0), or if the humidity sensor is not connected on the unit (P08 = 0), selection 9ill

not be enabled. If selected, the dead band for automatic s9itching on the air side 9ill be brought to 5°C.

17.2 - LOGIC• Once selected, the Dehumidification logic sets the target

humidity level as the humidity present at the time thefunction 9as selected minus 10n. Where the roomhumidity is less than 40n the target level 9ill be set at30n.The fan 9ill be forced to run at lo9 speed or, if thetemperature is much higher than the setpoint, at mediumspeed.

• To bring the humidity to the programmed value, theventilation (and the valve, if present) 9ill be activated inthe event the ambient temperature reaches the setpointvalue. Should the room temperature fall too far belo9 thisthreshold, the logic 9ill be temporarily inhibited.

17.3 - WATER CONTROL• Enabling of the dehumidification function is tied to the

9ater temperature. The activation logic is sho9nopposite.

• If enabling conditions do not exist, the Dehumidificationfunction 9ill be temporarily inhibited.The same 9ill occur in the event that the probe is disconnected.

• Note:As soon as the reference humidity level is reached (or after having set the control to Off), dehumidification 9ill bedeactivated.

17.4 - DISPLAY• The display sho9s the follo9ing information:

• Use the Yeys to change the value on the display until arriving at the pass9ord for self-diagnosis 030, and press. The follo9ing message appears:

• Press the Yey to s9itch on the various thermostat outputs in sequence.

18 - ALARM SENSORSThe controller monitors t9o types of faults:

• Faults causing the thermostat to shut do9n.• Faults not causing the thermostat to shut do9n but 9hich prevent possible critical functions.• Code 01 = error on the remote ambient air temperature sensor (thermostat installed

on the unit) => Thermostat shut do9n.

• Code 02 = error on the internal air temperature sensor => Thermostat shut do9n.

• Code 03 = error on the 9ater temperature sensor (if connected) => Does not causethe thermostat to shut do9n.
