Hi guys,
I've got a city multi system, PUMY-P140YKM1 outdoor, one of the indoor units PEFY-P32VMS1 shows h0 then controller goes blank. (PAC-YT52CRA) No centralised controller.
Electrician on site has just confirmed there is 240V to the indoor unit.
System was installed by ourselves last year, with another 3x PUMY systems, commissioned by Mitsubishi, so all addressing etc ok, any help on what to start looking at before I go to site? (500 mile round trip)
Many thanks,
