Hello,
It is because the charge temp.
When I use temperature below 0?, the chiller and charge loop will not work normally.
When I change the supply chw temperature to 0?(ice-making chiller), and change the charge loop temperature to 0? the charge loop will work.

But change the temperature setting is not very correct, because actually ice-making chiller will not work at a higher efficiency (0? supply CHW).

All friends,
Do you find this bug?
