TESTING THE RF COMMUNICATION
It is important to site the Receiver, One Touch Override and RT500 in
locations where the RF signal cannot be interrupted.
The receiving range between RT500, One touch Override and Receiver 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 back
plasterboard, metal objects such as filing cabinets, general RF interference,
etc.
The range is generally large enough for most household applications, but it
is advisable to test the RF transmission from the intended RT500 and OTO
locations to the Receiver location before deciding where to mount the units.
To check the RF reception, follow the following steps:
1. Press the UP button on the RT500 until the set point
temperature is 3ºC higher than room temperature.
2. Wait for a few seconds. The flame indicator (heat call) should
appear on the bottom left of the LCD on the RT500.
3. Check the green LED on the receiver unit - it should be lit.
4. Select setback of OTO, press the big button to transmit the setback
signal to the Receiver. The green LED on the Receiver should be turned
off. This can test the RF range between the OTO and the Receiver.
5. Press the DOWN button of the RT500 to adjust the set point
temperature to be lower than room temperature.
6. Wait for a few seconds, and the flame indicator (heat call)
should disappear and the green LED should switch off.
7. Repeat steps 1 to 6 to make sure the LED in Receiver can turn on
and turn off each time.
If you are unable to get a stable RF connection between the Receiver and
RT500, check that the Receiver is both switched on and has a mains supply
(red LED lit). If this isn’t the problem you can also alter the RF address code
by following the ‘RF Address Code Setting’ section of this manual, and then
repeat steps 1 to 5. See page 14 and 15 of this manual.
