These system examples are merely recommendations
and must therefore be checked on site for completeness
and function.
The heating circuits must be regulated by an external
control unit.
Connect three-phase consumers via additional
contactors.
For multi boiler systems, the cascade and DHW tank
temperature must be controlled by a higher third party
control unit.
For multi boiler systems, all the relevant coding
addresses must be set on each Vitotronic 100.
For connecting a single boiler system to a higher third
party control unit, see page 62.
For connecting a multi boiler system to a higher third
party control unit, see page 66.
