3. Pairing CRXSL with heaters
This must be done, otherwise the heaters will not work.
Power up the CRXSL (see section ‘Power options’ for details).
There are 2 different sequences used for pairing. The sequence
used will depend on the heater.
To find out which sequence to use, check the heater rating
label and identify the model number.
If the heater is ‘RX’ and the last two digits are lower than 10 use
sequence 1.
If the heater is ‘RX’ and the last two digits are 10 or higher use
sequence 2.
If the heater is ‘SL’ use sequence 2.
If the rating label is not visible, follow the steps below:
Ensure the heater is switched OFF.
Switch the heater ON and observe the LED status light.
If the LED flashes red then goes green use sequence 1.
If the LED is solid green use sequence 2.
Sequence 1
Set heater into pairing mode as follows:
1.
Locate the heater LED status light.
2.
Turn power to the heater ON. Count 4 seconds, or
count 5 red flashes of the status light on the heater.
Turn power OFF.
3.
Turn power back ON. The heater status light should
be flashing green.
(If the light is not flashing green, the 4 second timing
was incorrect. Repeat step 1.)
4.
The heater is now ready for pairing with CRXSL.
The next 3 steps must be done within 30 seconds. After 30
seconds the heater will return to normal operating mode. Set
the CRXSL into pairing mode as follows:
1.
Touch and hold and icons together for 5
seconds.
2.
The display will show CRXSL identification code.
3.
Touch the button while the light on the heater is
flashing green.
If the pairing was successful, the light will stop flashing and the
heater is paired with CRXSL. This has to be done within 30
seconds. After 30 seconds, the CRXSL will return to normal
operating mode.
Sequence 2
Set heater into pairing mode as follows:
1.
Locate the heater status light.
2.
Turn power to the heater ON. The light should be
solid green.
The next step must be done within 20 seconds. After 20
seconds, the heater will return to normal operating mode.
Set the CRXSL into pairing mode as follows:
1.
Touch and hold and icons together for 5
seconds.
2.
The display will show CRXSL identification code.

3 times.
3. Pairing CRXSL with heaters (cont’d)
If the pairing was successful, the light will show red and
the heat output will switch on and stay on if the CRXSL is
signalling the heat output to be on. If the CRXSL is
signalling the heat output to be off, the heat output will
only switch on for a short period of time to show pairing
was successful.
