I have a confession to make however... I have been a dimwit.
I had the fan option in PP2000 set as 2 or 3 speed fan (because I thought it WAS a 2 speed fan). Anyway should have set it as 'controlled by chopper'.
Working properly straight away now. Off when engine started whether aircon on or not. Pulled the temp sensor plug and on it comes.
