Climaveneta WRAT SL 1804 Problem

[hitmanzak]

Hi all, just attended a Climaveneta WRAT SL 1804 with CVM 3000c controller and CT 3 showing E103 fault - compressor thermal overload protection, checked over load and thermistor and both appear to be ok. I have no electrical drawings for this unit so a bit stuck with where else this particular control circuit goes, does it go straight back to the PCB as an input, if so where?
Any help would be great or a drawing.
cheers

Cant reset the controller, is there a special technique, fault LED stays on for Comp 3, tried power reset, tested thermistor, electrical overloads, if the manual can shed any light then please send on, by the way i have the manual for the controller but not the chiller.

cheers

Turn off then on the main switch on the chiller.
