7 Cooling function
Note
If the temperature at the store sensor reaches 95 °C, the cooling function
will be blocked. The switch-on hysteresis is -5 K.
Note
If the cooling function is activated, the drainback option will not be avail-
able.
Store cooling
When the store cooling function is activated, the controller aims to cool down the
store during the night in order to prepare it for solar loading on the following day.
If the adjusted maximum store temperature is exceeded and the collector temper-
ature falls below the store temperature, the system will be reactivated in order to
cool down the store.
DTCO and DTCF are used as the reference temperature differences.
