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
• The Heat Pump
• A BT-WR02 paired on the BT-CT02 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.
The H&C mode is then propagate over all the system.
Only one device is the system should be able to select the H&C mode (Master H&C device). Other possible H&C switch signal
sources:
• BT-CT02 RF Central unit.
• H&C input on WFC-03 HC RF controllers.
• Digital thermostat configured as a Master H&C thermostat in manual or automatic mode.
The DIP switch on the WFC-03 HC RF controllers allows to select the device in charge of the H&C mode (Master H&C device).
The time before H&C switch is defined by the DIP2 (See 3.3):
• DIP2 = OFF. 2 seconds.
• DIP2 = ON. 5 minutes.
