4. Inputs / Outputs
4.1 Power Supply
4.2 Heating/cooling Input
Purpose:
This input allows switching the regulation mode for the system: Heating or cooling.
Source of the signal:
• A mechanical switch
• A Heat Pump
• A BT-WR02 RF paired on the BT-CT02 RF central unit as an ON/OFF device. This solution allows
getting a remote control of the H&C mode from the application.
Format of the signal:
The input could be free contact or live contact 230V.
Only one device in the system should be able to select the H&C mode. Other possible H&C switch signal source (See 3.3).
• Central unit (Set Manual H&C mode in the installer menu of the central).
• WFC-03 HCM RF 230 which embeds an H&C input.
• Digital thermostat configured as a Master H&C thermostat in manual or automatic mode (only one thermostat
per installation).
If you have multiple WFC-03 HC RF in the system, the H&C mode should be controlled by only one controller:
• Without central, the system considers the controller set as the Main WFC-03 HC RF (Please refer to 5.1.2)
• With central:
. The controller which controls the H&C mode. DIP#4DIP#5= WFC-03 HC RF.
. The controller which does not control the H&C mode. DIP#4DIP#5= Central Unit BT-CT02 RF.
