Hi All,
Got a problem with a misubishi/daiya Unit
Model FDCP508HES3 R407 3 phase.
Problems: Outdoor unit not cutting in, fitted gauges only 20 psi each side poss low on gas, do they have LP Switches ?
To test my theroy i put in 150psi of OFN & disconnected the wires from the compressor and switched on to see if the contactor pulled in (It Didn't).
Quick look at the diagram it looks like the A1 of the contactor comes off a relay which switches fom the crank heater to the A1 does this mean the A1 which comes off output 52c on the board only comes on once the crank heater has warmed the pot up. If so how does it tell when its wam enough.
I couldn't find a leak to left the unit under pressure overnight to see how much it drops.
There are wo LED's on the board, one red & one green. Nothing going on the the red but the green one just keeps flashing, as far as i am aware this means the system should be OK.
Just had another thought, The label on the unit say's Mitsubishi/daiya Heavy industries. Does this mean its from a seperate part of the mitsi empire than the one that makes the M Series. Sould have also said the fault codes i was getting was U57 E01, I am assuming this is a general outdoor fault code but cannot see this on any Mitsi list i have got.
Any help would be appreciated.
Regards
Raymond
