RF Address Code Setting
If there is another unit being used nearby, e.g. in the next house or as part of a multiple installation,
your Receiver may be triggered by the other Control Unit. You can change the RF Address Code to
help to prevent this problem.
Each Receiver can only respond to RF transmissions from a Control Unit that has the same RF
address code setting.
Disconnect the mains power to the Receiver, and remove the batteries from the Control Unit before
attempting any adjustment of the RF Address Code switch and jumpers. If you are not sure how to
carry out this operation correctly, consult either with a qualified electrician or heating engineer.
To adjust the RF address code of the Receiver, simply push up one or more of the 5 DIP switch
levers on the DIP switch bank located on the back of the Receiver, and then make a note of the
setting of each switch. Then set the 5 DIP switch levers on Control Unit same as the RF Receiver
setting so that the address code settings match each other.
For example, if Receiver DIP switches set as following,
Controller unit DIP switch should be set as same:
You must press
Reset
on the Control Unit after making any changes to the RF address code
settings.
Testing the RF Transmission
It is important to site both the Receiver and Control Unit in locations where the RF signal cannot be
interrupted.
The receiving range between Control Unit and Receiver is approximately 30 meters 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, but it is advisable to test the
RF transmission from the intended Control Unit location to the Receiver location before fixing the
Control Unit to the wall. To check the RF reception, follow the following steps:
1. Press the button on the Control Centre until the set point temperature is higher than room
temperature by a few degrees.
2. Wait for a few seconds. The Burner on (heat call) indicator should appear on the bottom left of
the LCD on the Control Unit.
3. Check the green LED on the receiver unit – it should be lit.
4. Press button to adjust the set point temperature to be lower than room temperature.
5. Wait for a few seconds, and the Burner on (heat call) indicator should disappear and the green
LED should switch off.
6. If at step 3 the green LED is not illuminated, press the
Reset
on the Control Unit and try to place
the Control Unit closer to the Receiver.
7. Repeat steps 1-5.
If you are unable to get a stable RF connection between the Receiver and Control Unit, check that
the Receiver is both switched on and has a mains supply (orange 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 should then repeat steps 1 to 5 (note that the
Reset
button on the Control Unit should
be pressed after altering the address code.)
1 – ON
2 - OFF
3 - OFF
4 - OFF
5 - ON
