RF205 Series
Programmable RF room thermostat
RF205-TS programmable room thermostat (transmitter) T55 (Receiver)
1. General
The RF205-TS is a radio controlled room thermostat which requires no wiring and is designed to be fitted in a
conventional household installation, at a maximum 30 metres range of the T55 “boiler module”, which is a
boiler-mounted modular receiver.
The T55 receiver must be installed by a qualified installation engineer. Do not place it too close to objects
which might interfere with the radio signal. It is preferable to mount the receiver such that an imaginary
straight line between it and the transmitter thermostat is not obscured by the boiler or any other large metal
objects such as kitchen appliances. When installing these devices, please avoid touching the PCB as static
damage can occur.
The RF205 control set has already been commissioned, or matched, in the factory. Just connect power to the
receiver / put batteries in the transmitter, and the set will communicate. If for any reason you wish to verify
the RF link please refer to the fourth option under section 7. Configuration Setting
