TESTING THE RF TRANSMISSION
It is important to site both the receiver and thermostat in locations where the RF signal cannot be
interrupted.
The receiving range between thermostat and receiver is approximately 30 metres indoors, however
many factors can affect the RF transmission and shorten the operating distance, e.g. shielding by thick
walls, foil back plasterboard, metal objects such as filing cabinets, general RF interference, and so on.
The range is generally large enough for most household applications, to check the RF reception, follow
the following steps:
1. Turn the thermostat to 30ºC. The LED under the dial should come on.
2. Check the Green LED on the receiver unit - it should be lit and boiler should fire.
3. Turn dial down to 5ºC. The LED under the dial should go off.
4. Wait for a few seconds and the Green LED should switch off. The boiler should also switch off.
5. If the operation of 1-4 is successful then you have a good RF link between the thermostat
and the receiver.
6. Return the dial to the preferred set temperature for the application.
If you are unable to get a stable RF connection between the receiver and thermostat, check that the
receiver is both switched on and has a mains supply (red LED illuminated). If this isn't a problem then
try pairing the thermostat to the receiver again. See page 8.
