6.4 DHW heating with solar system
The systems Anl 1.3 and 2.3 include a solar system for DHW heating. In these systems, the
difference between the temperatures measured at storage sensor SF2 and the sensor at the
solar collector VF3 is determined. The
Solar pump ON
parameter determines the minimum
temperature difference between sensors VF3 and SF2 required to activate the solar pump. If
the temperature difference falls below the value of
Solar pump OFF,
the solar pump is
switched off. Basically, the solar pump is also switched off when the water temperature mea
-
sured 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 pump are dis-
played in extended operating level.

Solar pump ON 10 °C PA4 / 1 to 30 °C

6.5 Intermediate heating operation
This function is only available in systems Anl 2.x, 4.1 and 4.5. With the setting
CO4 -> F07 - 1, heating operation of the UP1 heating circuit is reactivated for a period of
10 minutes after 20 minutes of priority (heating deactivated during DHW heating). By setting
CO4 -> F07 - 0, storage tank charging is given unlimited priority over the heating operation
in the UP1 heating circuit.
