4-4-8 Simultaneous Indoor Heat Exchanger's EVA IN, OUT sensor dislocation error (Open/Short)
1. How to diagnose
1) During Cooling Operation
Tcond, out - Tair, out > 3°C
Tair, in - Teva, out > 4°C
Tair, in - Teva, out > 4°C
Compressor in operation &
Indoor unit operation & Thermo On
Error details
2) During Heating operation
Average high pressure > 25kg/㎠
Average low pressure > 8.2kg/㎠
Teva, out - Tair, out ≥ 3°C
Tair, in - Teva, out ≥ 2°C
Tcond, out - Tair, out < -2°C
Compressor in operation &
Indoor unit operation & Thermo On
