OpenTherm® Instructions
It is possible to have up to six CP4D thermostats controlling one
OpenTherm® boiler. To do this it is necessary to make one of the RF1B
receivers into a Hub Receiver. This Hub Receiver will receive data from
all of the RFRPD
thermostats and relay this information to the boiler via
OpenTherm®.
Note: The Hub Receiver should have a wired OpenTherm® connection to
the boiler. When installing multiple receivers - see important on page 15.

1. The RF1B has an LED to indicate if it is a Hub.
2. Press and hold
