Anti-freeze alarm configuration in heat pump
0= to turn the compressors off when the anti-freeze control probe is
lower than AL33 (after the time delay), the display shows the alarm
label.
Buzzer and Alarm relay are not activated.
1= to turn the compressors off when the anti-freeze control probe is
lower than AL33 (after the time delay), the display shows the alarm
label.
Buzzer and Alarm relay are activated.
