6 Installing the CM721 wireless system
General 6.1
Note: The individual room thermostat (CM721) and relay box (BDR91) in system packs is pre-configured at the
factory and therefore SHOULD be installed at the same site.
This makes the installation process fast and easy, but if products from individual system packs are separated,
or mixed with other pre-configured system packs during installations please refers to
section 7 Binding/rebinding the CM721, to bind the desired units together and allow them to communicate with
each other.
The CM721, room thermostat communicates with the relay box on an 868MHz Radio Frequency (RF) band to
control a single heating system component such as a boiler, pump or zone valve. Neither product will
communicate with other RF products that use different frequencies or communication protocols.
