Hi Guys,

Briefly looked at this last week - seems to run ok on cooling. Indoor is PLA-RP100BA cassette.

Heating - gets past the preheat for about 5mins then goes off on a U9 Fault.
Seems to not be ramping up to full speed. Pipe sensor (I think this the liquid 3/8) on remote (PAR-21) gets to 39/40deg max.
I did manage the get it to run full speed but only briefly on test mode.
Checked there is definitely 240V at the mains in connection.

Before I return, are there any obvious/common things I need to check?
Service manual is showing a few connections to check.

Thanks,
