RFRP-OT OpenTherm® Instructions
It is possible to have 6 CombiPack4-OT controlling 1 OpenTherm® boiler.
To do this it is necessary to make one of the RF1A-OT receivers into a

thermostats and relay this information to the boiler via OpenTherm®.
Note: The Hub Receiver should have a wired OpenTherm® connection to
the boiler.
1. Press the Reset
button on the receiver that you wish to make
the Hub Receiver – Red and Green lights are both solid.
2. Immediately press and hold the
and buttons for 5
seconds, the red light will start blinking.
3. Press the
button and the Green light will be solid – this is now
the hub receiver.
