7.4 Domestic hot water heating with solar system
The systems Anl 1.3 and 2.3 are tted with a solar system for DHW heating. In these sys-
tems, the difference between the temperatures measured at storage sensor SF2 and the sen-
sor at the solar collector VF3 is determined. The 'Solar circuit pump ON' parameter deter-
mines the minimum temperature difference between sensors VF3 and SF2 required to acti-
vate the solar circuit pump. If the temperature difference falls below the value of 'Solar circuit
pump OFF', the solar circuit pump is switched off. If the temperature difference falls below
the value of 'Solar circuit pump OFF', the solar circuit pump is switched off. Basically, the so-
lar circuit pump is also switched off when the water temperature measured at sensor SF2 has
reached the 'Max. storage tank temperature'.
Note:
The times-of-use of the DHW circuit do not affect the operation of the solar system.
After the key number 1999 has been entered, the operating hours of the solar circuit pump
are displayed in the extended operating level. See page9.
