3 BINDING THE WIRELESS
THERMOSTAT AND RF RECEIVER
By default the thermostat is already linked to the RF receiver.

in case it is only required one wireless thermostat at the
installation.
The binding operation described below is required if:
• Any of the system components (Room Thermostat or
RF Receiver) are replaced. Go to step 1.
• The RF Receiver has incorrect or no binding data stored
(e.g. when pre-bound system pack components have been
mismatched). Go to step 1.
• When adding a second wireless thermostat. Go to step 2.
