0
Temperature control by b1, activation by b3 (ambient
temperature sensor)
1
Temperature control by b3 (ambient temp. sensor) with
ARA set point.
4.7.8.2. AbrA antifreeze heater activation mode
0
Activation only when controller is ‘On’
1
Activation also when controller is ‘Off’
2
Activation also when controller is ‘Off’. During heater
operation the pump is activated.
Notes: this function allows antifreeze protection with low
ambient temperature conditions and the chiller in OFF.
Operation :
1) when probe b3 (optional) detects temperatures below 5
° C, the 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 5 ° C.
