Vitosolic 100 or Vitosolic 200 at KM-BUS
■ If a solar circuit is connected to the HKK, no
Vitosolic 100 or Vitosolic 200 may be connected to
the KM-BUS.
■ If a solar circuit is controlled via a Vitosolic 100 or
Vitosolic 200, only reheating suppression can be car-
ried out via the KM-BUS connection.
A Vitosolic 100 or Vitosolic 200 can be connected to
■
the KM-BUS in addition to 3 extension kits.
