TESTING THE RF TRANSMISSION
It is important to site the RT500 in locations where the RF signal cannot be
interrupted.
The receiving range between the RT500 and the Boiler Control is 70 metres
in open air, however many factors can affect the RF transmission and shorten
the operating distance, e.g. shielding by thick walls, foil backed
plasterboard, metal objects such as filing cabinets, general RF interference,
and so on.
The operating range in most household applications is around 30 metres,
which should be more than adequate in most cases. It is advisable to test
the RF transmission from the intended RT500 location to the Boiler Control
location, particularly if you intend to fix the RT500 to the wall. To check the
RF reception, follow the following steps:
1. Press the UP button on the RT500 programmable room thermostat until
the set point temperature is higher than room temperature by a few
degrees.
2. Wait for a few seconds. The "boiler on" (heat call) indicator
should appear on the bottom left of the display on the RT500.
3. Check the LED (light) on the Boiler control - it should be lit.
4. Press the DOWN button to adjust the set point temperature
to be lower than room temperature.
5. Wait for a few seconds, and the "boiler on" (heat call) indicator should
disappear and the LED (light) on the Boiler Control should switch off.
6. Repeat steps 1 to 5 to make sure the LED (light) on the Boiler Control can
turn on and turn off each time.
If you are unable to get a stable RF connection between the Boiler Control
and RT500, check that the Boiler Control has a mains supply. If this isn't the
problem you can also alter the RF address code by following the 'RF ID Code
Setting' section of this manual, and then repeat steps 1 to 5.
