R205 Series Wireless heating Thermostat
R205 LCD Heating Thermostat
1.General
R205 is a Radio Controlled Room Thermostat which requires no wiring and can be fitted in any normal operating
enviroment within a typical 30 meter range of the TR205 RF Transceiver. It is available for Non-programmable and
Programmable.
AC819 Transceiver should be mounted on a vertical flat surface near the boiler or centrial heating wiring centre.
Do not place it too close to objects which might interfere with the radio signal. It is preferable to mount the
transceiver such that an imaginary straight line between it and the transmitter thermostat is not obscured by the
boiler or any other large metal objects.
