Cause of problem
×
(Operation) ◑ (Timer) ◑ (Fan) ◑ (Filter) × (Defrost)
• Oil valve (balance keeping valve)’s temperature sensor dislocation
• Oil valve (balance keeping valve) breakdown
• Coil defect or terminal contact defect
Criteria
1. When only one outdoor unit is installed, it does not diagnose
2. When more than 2 outdoor units are connected and exchange their oil, the oil valve (balance keeping valve)
1 is broken or temperature sensor of breakdown detection for balance keeping valve 1 is dislocated, the error
is displayed.
3. When temperature rises for more than 5bC after closing balance keeping valve 1 and opens hot gas bypass
before entering a balance keeping operation, the error is displayed.
4. At the stage of releasing oils during balance keeping operation, if there is less than 44.6°F/7°C temperature
change after opening an oil valve (balance keeping valve) and opening the hot gas bypass, the error is displayed.
