Abstract (en)
A control system for a central heating system comprises at least one thermostat (6) functioning as a transmitter and arranged to transmit data to a receiver unit (4) communicating with a programmer (2). To avoid any risk that the receiver (4) will receive command messages substantially concurrently from two different transmitters (6), each transmitter is arranged to randomise the timings of its transmissions. A twelve bit identification code (36) contained in each command message and unique to the corresponding transmitter is used to effect the randomisation. <IMAGE>
