How can resolved PJ error in daikin vrv 2


PJ is an error that has to do with the outdoor unit not matching the indoor unit. This means the outdoor board thinks it's a 2 ton unit and the indoor thinks it's a 1 ton unit. (Just throwing those numbers in)...but, the indoor is not matching the outdoor. You need to read the manual and go through the setup process.

My air conditioner has just stopped working with error code CH61 what does this mean?


Not enough air being drawn over the outside condenser unit. This could be for a number of reasons. The unit may be covered, restricted, or blocked. The condensor fan may be inoperable on the unit. Without a model number I would first check the outdoor fan for proper operation, and contactor and run capacitor. It sounds as though the compressor is coming on and going into thermal overload.
