Diagnostics
Below is a break down of the flash sequence giving an indication of the area which is at fault. If there is a fault present the controller will indicate the fault by a series of flashes.
The status LED next to the reset button on the right hand side dial will flash blue. In the event of an error, the LED will flash initially (which should be ignored), pause and then flash in sequence to show the errors below.
The status LED will flash to indicate the fault. The status LED will continue flashing until the fault is rectified and the keyswitch has been cycled.
