Hi guys,
Having a problem with a City Multi PURY P500YGMA.
Unit has 12 indoor units, 2 BC's.
There was complaints of poor heating performance in the areas being fed by the slave BC. Checked the outdoor unit and found the system running but the suction heavily iced up and the evaporator slightly iced up. PAR27 controllers showing "DEFROST" frequently also.
Units seemed to be working fine up until two weeks ago when the ambient dropped dramatically from about 14 degrees to 5-6 degrees celcius.
I read somewhere that sometimes the LEV's (not sure which one) can open and bypass the indoor coils and therefore flooding the suction returning to the compressor? am I right or way off? could LEV 3 in the slave BC be faulty? or the temp sensors controlling it?
Any thoughts guys?
thanks in advance
