Register sensors:
The first registered sensor works as the master. Each sensor must be registered separately.

1: Disconnect power from the RF ventilation unit(s)

  • If you have a WHR unit, first set P850 to 1

2: Wait at least 5 sec, turn the power of the ventilation unit back on. There is now 10 minutes to register 1 RF control.

3: Hold the push button for at least 8 sec. until the LEDs start flashing.

4: Test if the registration was successful by setting the sensor to the maximum position. If the unit goes to high, the registration was successful, otherwise repeat steps 1 to 3

A CO2 master control is not compatible with an RFZ, only with an RF timer.
