1. Getting to know your CRX2 wireless controller
Please read this guide carefully and retain for future use and maintenance.
This must be done, otherwise the heaters will not work.
Power up the CRX2 (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 last two digits are lower than 10 use sequence 1.
If the last two digits are 10 or higher 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.
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 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 CRX2.
The next 3 steps must be done within 30 seconds. After 30
seconds the heater will return to normal operating mode. Set
the CRX2 into pairing mode as follows:

heater to be off, the heater will only switch on for a short
period of time to show pairing was successful.
