Suppression of reheating by the boiler with central heating backup, with solar control module

If a sufficiently high temperature is available in the multi-mode heating
water buffer cylinder to heat the heating circuits, reheating is sup-
pressed.

Auxiliary function for DHW heating with solar control module

For detailed information see chapter "Auxiliary function for DHW heat-
ing".
Enabling the auxiliary function for DHW heating must be encoded at
the boiler control unit. The solar preheat stage can be heated up at the
selectable times.

Auxiliary function for DHW heating with Vitosolic 100

For detailed information see chapter "Auxiliary function for DHW heat-
ing".
Only possible in conjunction with Vitotronic control units with KM
BUS.
Control units from the current Viessmann product range are equipped
with the necessary software. When retrofitting an existing system, the
boiler control unit may have to be equipped with a PCB (see
Viessmann pricelist).

Boiler control unit settings:
■ The set DHW temperature 2 must be encoded
■ The DHW phase 4 for DHW heating must be enabled
Via a KM BUS, this signal will be transferred to the Vitosolic 100, and
the transfer pump will be started.
