4.3 Pump Output
There are 2 outputs:
• Live contact output (230Vac).
• Free contact output.
These outputs can be used to trigger:
• A zone valve.
• A pump.
• A boiler or heat pump.
The 2 outputs are triggered when there are a heating or cooling demand, which is sent by the WFC-03 HC RF controller to the
WFC-03 HCM RF 230.
The pump signal is always global, i.e. the pump is triggered when there is a heating or cooling demand within the system.
If a RF failure occurs, the pump is triggered all the time.
4.5 Dehumidifier output
When DIP1 = ON (See 3.3), the dehumidifier output (Free contact) is triggered in 2 cases:
• When the Humidity input is triggered (See 4.4).
• When the WFC-03 HC RF controller orders the dehumidifier.
4.4 Humidity detection input
When DIP1 = ON (See 3.3) the product manages a humidity detection input, with 2 possible types of signal
depending on DIP4 (See 3.3):
• Water temperature sensor (NTC 10kΩ): Require BT-D03 RF RH thermostat.
• A humidity contact sensor.
4.4.1 Humidity contact sensor
Format of the signal:
The input is a free contact
When humidity is detected by the sensor, the information is sent to the WFC-03 HC RF controller which manages the information.
Moreover the dehumidifier output is triggered.
4.4.2 Humidity contact sensor
The water temperature measurement is sent to all WFC-03 HC RF controllers to compute the dew point for humidity control in
cooling mode (Please refer to the leaflet of WFC-03 HC RF).
No Humidity Opened contact
Humidity detected Closed contact
