Example
set = 7°C; dif = 4 ° C; ambient temp. <10°C
- when the water inlet temperature reaches 9 ° C (7 + 2) :
compressor 1 starts;
- when the water inlet temperature reaches 11 ° C (7 + 4):
compressor 2 starts.
set = 7°C; dif = 4 ° C; ambient temp. >10°C
- when the water inlet temperature reaches 11 ° C (7 + 4) :
compressors 1 and 2 starts;
