Daikin E2

Critical

VRV / Sky Air — E2 = current leakage detected in the earth-leakage detection circuit (triggers when leakage current is sensed). Causes: earth fault (defective wiring or current sensor), defective compressor insulation (or insulation of other parts), or temporary liquid back / refrigerant stagnation.

Daikin E2: E2 = current leakage detected in the earth-leakage detection circuit (triggers when leakage current is sensed). Causes: earth fault (defective wiring or current sensor), defective compressor insulation (or insulation of other parts), or temporary liquid back / refrigerant stagnation. This fault typically halts operation and needs immediate attention.
