If the DHW temperature is lower than the current setpoint minus the switching
differential set here, DHW charging is started.
DHW charging is completed when the temperature reaches the current setpoint.
When DHW heating is released for the first time in a 24-hour period, forced charging is
initiated. DHW charging is also started when the DHW temperature lies within the
switching differential, provided it does not lie less than K below the setpoint.
Line no. Operating line
5030 Charging time limitation
During DHW charging, space heating may obtain no or too little energy, depending on
the selected charging priority (1630) and the type of hydraulic circuit. For this reason, it
is often practical to set a time limit to DHW charging.
- - -
Charging time limitation is deactivated. The DHW is heated up to the nominal setpoint,
even if space heating cannot draw sufficient heat for a certain period of time.
10 – 600
DHW charging is stopped after the set period of time in minutes and then locked for the
same time before it is resumed. During this period of time, the heat produced is made
available for space heating. This cycle is repeated until the nominal DHW setpoint is
reached.
When space heating is off (summer operation, Eco function, etc.), DHW charging is not
stopped, independent of the selected setting.
Line no. Operating line
5050 Charging temp max
The solar collector charges the DHW storage tank until the set "Charging temp max" is
reached.
The protective collector overtemperature function can reactivate the collector pump
until the maximum storage tank temperature is reached.

An activated recooling function remains in operation until the set recooling temperature
in the DHW storage tank is reached.
Excess heat can be drawn off either by space heating or the DHW storage tank. Heat
consumption via a heating circuit can be set separately for every heating circuit (menu
"Heating circuit X...").
When the collector is cold, surplus energy can be emitted to the environment via the
collector's surfaces
