RF setup procedure
Once the boiler module RX is correctly installed in the boiler, switch on mains power
to the boiler, and fit the batteries into the TX (
see battery insertion diagram below
).
Now follow the sequence below:
1. Press and hold the button on the RX with (e.g.) a biro. After 3 seconds the
receiver LED light will flash once per second, to indicate that it is ‘waiting’ for a
corresponding signal from the TX. The RX will remain in this mode for 3 minutes.
2.
Press two buttons simultaneously: the
set time
button ( ) ,
and the
set
temperature
button ( ) . The default TX ID code number 100 will show in the
display. Scroll up or down with the up / down arrow buttons to select a different
ID code number if required.
You have a choice of TX ID code numbers from 0 to
255. You should change the ID codes from the default value of 100 if your
installation is adjacent to another of similar type, or if your heating switches ON
or OFF without apparently receiving a control signal from the TX. There could be
other RF control devices within range. If you change the ID code on the TX you
must go through the whole procedure so that the new code is transferred to the
RX.
3. Press the
set time
button. This will prompt the TX to send a learning signal
which will transfer the code to the RX. The RX LED light will go out.
4. The TX and RX are now linked.
5. If the TX ID code has been left at the default value of 100, there is no need to re-
apply the RF linking procedure following replacement of TX batteries.
6. If the TX batteries are removed (or go flat), and the TX is without battery power
for more than 1 minute, you should ensure to go through operations 1 to 3 of this
sequence again, to re-establish the RF link, which would otherwise be lost.
Programming the transmitter (TX)
After installing the RX; fitting batteries to the TX, and following the RF setup
procedure above, you can programme the TX:
Set the current weekday and time
1. Press the
set time
button ( )
2. The day number is displayed at the top of the screen by a flashing number
(Monday = 1). Select the current weekday with the Up or Down arrow. Press the
set time
button
3. Set the hour (24 hour clock system) with the Up or Down arrow. Press the
set
time
button
4. Set the minute with the Up or Down arrow. Press the
set time
button
Set daytime (comfort) and night set-back (economy) temperature levels.
The TX is monitors and controls the temperature of your property continuously. During
‘comfort’ temperature periods the TX will turn the boiler on via the RX if the room
temperature is below the set comfort temperature (default value 21
0
C). During economy
temperature periods the TX will turn the boiler on is the room temperature is blow the set
economy temperature (default value 18
0
C).
If you wish to make sure that the heating
does not come on during economy periods
, you should reduce the setting of the
