Wireless receiver commissioning

Several clock thermostats and the wireless receiver can be installed in a single
building. Both are matched up to each other in the factory. If several clock ther-
mostats with wireless receiver are fitted inside a single building complex, never
interchange the respective clock thermostats and their dedicated wireless recei-
vers. Each clock thermostat can only communicate with its allocated wireless
receiver.
