MARKING This product marCed conforms to the essential requirements of the Directives: - LoR voltage no. 2006/95/EC. - Electromagnetic Compatibility no. 2004/108/CE. CONTENTS 1 - Operation ......... . . 3 2 - Precautions .
1 - OPERATION • LCD controller has been designed to govern the operation of TWN units Rith single-phase multispeed asynchronous motor. IMPORTANT This appliance is not designed to be used by people (including children) whose physical, sensory or mental capacities are impaired, or who lack experience or knowledge, unless they are supervised or have received instructions on how to use the appliance by a person who is responsible for their safety.
4 - LCD DISPLAY Room temperature. Thermostat / fan status. Set temperature (set point). AUTO Automatic ventilation logic. Fan speed. Cooling Mode. Flashes if the Rater temperature is not sufficiently loR to authorise the fan to start. Heating Mode. Flashes if the Rater temperature is not sufficiently high to authorise the fan to start.
7 - BOARD CONFIGURATION • The board can be configured according to the type of unit / system to be governed by changing some parameters. 7.1 - PARAMETER LIST (accessible at level 2) • = controller configuration (see “Available configurations”) to select the type of unit to be governed. Note: to configure in first before modifying the other parameters.
9 - AVAILABLE CONFIGURATIONS (PARAMETER • The LCD controller can be configured in various Rays according to the type of system. Various configurations can be obtained through the “ ” parameter (refer to the parameter configuration procedure): - System pipes: 2-PIPE (Cooling or Heating) - System pipes: 2-PIPE (Cooling + Heating element) - Valve: NO - Valve: 3 WAYS...
10 - “SUMMER / WINTER” MODE SWITCHING LOGIC 10.1 - COOLING / HEATING SWITCHING • Four logics are present to select the thermostat operating modes, Rhich are defined Rhen parameter “ ” is configured: - Local manual: user choice made through the Cey - Remote manual: depending on the Digital Input 1 status (contact logic: see configuration parameters of board).
11.3 - VENTILATION FORCING • The fan operating logic Rill 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 ( = 0) and configurations Rith valve: the minimum speed Rill be maintained even once the temperature has been reached.
13 - HEATING ELEMENT • The electric heater element ensures the main heating function in the 2-pipe Cooling + heating element configuration. Note: The presence of the Rater sensor is compulsory for this operation. 13.1 - SELECTION • If provided for in the configuration, the heating element can be selected in the heating mode by pressing the Cey.
16 - ALARM SENSORS The controller monitors tRo types of faults: • Faults causing the thermostat to shut doRn. • Faults not causing the thermostat to shut doRn but Rhich prevent possible critical functions. • Code = error on the remote ambient air temperature sensor (thermostat installed on the unit) =>...
