OpenTherm® Instructions
It is possible to have up to six CP4
V2
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 RFRP
V2
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.
Making your RF1B receiver into a Hub Receiver:
1. The RF1B has an LED to indicate if it is a Hub.
2. Press and hold
Manual
&
Connect
for 5 seconds to make the receiver a
Hub or Branch.
Note: A Hub receiver is the master receiver in multiple zone installations.
A branch receiver is used for connecting additional zones. See Page 50
for System Architecture.
Note: A Hub receiver can connect to a GW04 Wi-FI Gateway.
