Power up the HSTIRFN (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 ‘WX’ and the last two digits are lower than 10
use sequence 1.
If the heater is ‘WX’ and the last two digits are 10 or higher use
sequence 2.
If the heater is ‘RF’ 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.
