Notes: this function allows antifreeze protection with low
3.0
ambient temperature conditions and the chiller in OFF.
37.4
Operation:
1) when probe b5 detects temperatures below 41 °C, the
0.0
antifreeze function is activated and the pump turns ON;
2) probe b1 has the task of activating the resistance when
the water inlet temperatures drop below 41 °C.
