I have a Air-Con 2 ton split ductless heat pump in my shop. It worked great until recently where the control board in the inside unit keeps throwing an error code (E4, Condenser Abnormal).
I've gone through the troubleshooting steps mentioned in the manual and checked the charge. The last suggestion in the manual is a bad control board. But the system is old and I don't think I value it enough to find a new one or replace it. It seems to work fine until it errors out...
So... My question is: would it be a horrible idea to bypass all of the controls on the board and use a standard house thermostat? I know I would loose the remote control (don't care) and the movement offered by the vanes but I could live with them being in a fixed position. It just sends 240v out to the compressor contactor coil and fan from the inside unit so I think I could do it with a few 24Vac relays. Any thing I'm not thinking of? Anyone else done something like this before?
