Re: City Multi h0 fault code
Remote controller isn't talking to indoor PCB. If the system has been running for a period of time then I'd suspect a power cut has caused the problem or you have a faulty PCB. Get your electrician to check power supply's on all indoors and condenser and carry out full system reset. If this doesn't work enjoy your 500mile round trip
Re: City Multi h0 fault code
Thanks for the reply - I'm travelling to N.London tomorrow so going to call in.
Going to try a full system reset first, I believe this is SW2-2 on the outdoor? Any other steps?
Re: City Multi h0 fault code
Hi..Slim R410a,
switch off all the power of AC including outdoor units up to 1 minutes and switch on
the power of outdoor units and IDU then the setting will reset automatically.i hope
this will work you..
Re: City Multi h0 fault code
Went to site yesterday tried reset first, then found no M-Net voltage on the indoor unit. (last indoor in series so only has 1x 1.5mm 2core cable going into terminals M1 + M2)
Found 30Vdc on the next indoor along so looks like a damaged/mouse chewed through M-Net cable somewhere. Guys on site are going to try temporary cable between indoors to confirm when both rooms are next free. (busy hotel)
