5.3.3 Disabling heating sources depending on external air temperature
The value of the external air temperature is used as reference to disable the heating sources in the unit. The heating
sources are disabled when the temperature is either high or low.
The parameters involved are shown in the table.
The values of the parameters are representative. In specific cases, different values can be set.
Parameter Value UM Description
STH14 -20.0 °C Mechanical heating - Deactivation threshold for low external air temperature
STH15 30.0 °C Mechanical heating - Deactivation threshold for high external air temperature
STH123 -30.0 °C Auxiliary heating - Deactivation threshold for low external air temperature
STH124 50.0 °C Auxiliary heating - Deactivation threshold for high external air temperature
Heating generated using the refrigerant circuit is disabled when:
- the external air temperature is low - it drops below the setpoint in parameter “STH14”; heating is enabled again
when the temperature value rises above the setpoint in parameter “STH14”, plus +1°C;
- the external air temperature is high - it rises above the setpoint in parameter “STH15”; heating is enabled again
when the temperature value drops below the setpoint in parameter “STH15”, minus +1°C.
Auxiliary heating is disabled when:
- the external air temperature is low - it drops below the setpoint in parameter “STH123”.Auxiliary heating is
enabled again when the temperature value rises above the setpoint in parameter “STH123”, plus +1°C;
- the external air temperature is high - it rises above the setpoint in parameter “STH124”. Auxiliary heating is
enabled again when the temperature value drops below the setpoint in parameter “STH124”, minus +1°C.
