9.3 Fault detection
Heaters are equipped with electronic fault detection. In the event of a fault being detected, heater will show the nature of the fault by flashing the status LED located at the front of the heater. The LED will flash white in one of the sequences as shown in the table below. The sequence is repeated every 5 seconds.

Response: Power reduced until heater cools down
2| Temperature measurement fault
Response: Fan runs at high speed
3| Power not detected when heat switched ON
Response: Fan operates as normal
Possible causes: missing phase, blown fuse, faulty electronics
4| Problem with motor
Response: Heater will not work
5| Power detected when not switched ON
Response: Fan runs continuously
6| Internal communication error Response: Heater will not work

9.4 Over heat protection reset
The heater is equipped with electronic over heat protection and also resettable over temperature cut-outs. There are two cutouts located on the top of the heating element.
In the unlikely event of electronic failure, the mechanical cut-outs will switch off power to the heating element. In order to reset cut-outs, isolate the heater from power and leave heater to cool down.
The cause of cut-outs operating should be investigated before resetting as the only time the mechanical cut-out operates is when electronics can’t protect heater from overheating.
