Functions of the DHW circuit

Stop storage tank charging

The controller stops charging the storage tank when the water temperature in the storage tank measured at sensor SF1 reaches the value T = DHW heating ON + Hysteresis. In systems with two storage tank sensors, the controller stops charging the storage tank when the water temper- ature in the storage tank measured at sensor SF2 reaches the value DHW heating OFF. In sys- tems with storage tank thermostat, the Hysteresis of the thermostat determines when the storage tank charging is finished.

DHW heating from the secondary circuit (Anl 3, 8):

When a high flow temperature is required by the system, the heat exchanger charging pump is immediately switched off. If no heating is taking place or if the flow temperature demand in the system is lower, the End charging process parameter applies for switching off the heat exchanger charging pump.

The heat exchanger charging pump is switched off at the latest after two transit time periods of the control valve (2 x TY); 15 seconds after the heat exchanger charging pump has been switched off, the storage tank charging pump stops operating.

DHW heating from the primary circuit (Anl 5, 11):

The storage tank charging pump (Anl 5) or the heat exchanger charging pump (Anl 11) is switched off when the temperature reaches End charging process parameter, at the latest, how- ever, two transit time periods of the DHW control valve (2 x TY).

In system Anl 11, 15 seconds after the heat exchanger charging pump has been switched off, the storage tank charging pump stops operating.
