This is the Grasslin RF205 RF programmable digital room thermostat with its receiver, a radio controlled thermostat requiring no wiring. It can be fitted in a normal operating environment withint a typical 30m range of the RF205-RC RF receiver.
The RF205-RC RF receiver (included) should be mounted on a vertical flat surface near the boiler or central heating wiring centre. 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. When installing these devices, please avoid touching the PCB as static damage can occur.
