Storage tank temp max	If the storage tank reaches the maximum storage tank temperature set here, the
	collector pump will be deactivated. It will be released again when the storage tank
	temperature drops 1 °C below the maximum storage tank temperature.

The protective collector overtemperature function can reactivate the collector pump until the storage tank’ s safety temperature is reached.

Automatic push	The DHW push can be triggered either manually or automatically.
	With the DHW push, the DHW is heated up once until the nominal setpoint is reached.
	Off
	The DHW push must be triggered manually.
	On
	If the DHW temperature falls below the reduced setpoint (operating line 1612) by at
	least 2 switching differentials (operating line 5024), one-time charging to the nominal
	DHW setpoint (operating line 1610) will take place again.
	The automatic DHW push only works when the DHW operating mode is activated.
