Multi boiler systems
Every boiler in a multi boiler system must be equipped with a
Vitotronic 100 (type GC1B or GC4B). The Vitotronic 300-K (type
MW1B) is supplied with one boiler (see pricelist) and should be instal-
led separately.
The LON communication module must be fitted into the Vitotronic 100.
See pricelist.
In multi boiler systems with external control unit, the load-dependent
burner and boiler control as well as the cylinder temperature control
must be implemented by the higher ranking (external) control unit.
