protection

 Er41

1) Phase 

protection 

of power supply: 

When the chiller is powered on, if there is wrong sequence of power phase, lack of power phase, it will 
show Er41, the chiller can not run. 

2) Compressor 

current 

protection: 

If the operating current of compressor reaches the value below, system stops and shows Er41: 

Capacity ( kW) 

Compressor current value (A) 

Capacity ( kW)
