tact

Closed

Open

A

– The boiler is blocked and

has been removed from
the boiler sequence.

– Butterfly valve is closed

and the boiler circuit
pump stops.

– The other boilers provide

the required heating.

The boiler is integrated into
the current boiler sequence.

B

This boiler is started if the
other boilers in the heating
system cannot provide suf-
ficient heat.

The boiler is integrated into
the current boiler sequence.

.

Note
The contact at terminals 2 and 3 of plug 

aVH

 is always required to

prevent boiler damage.
This contact must always be closed on the lead boiler.

Hook-up of on-site control units via LON

The Vitotronic control units are equipped with an open standard LON
interface. With standard LONWORKS network variables (SNVT).
This universal, decentralised network for automated building control
systems not only allows communication between Vitotronic control
units, but also the hook-up of on-site systems and devices from various
manufacturers.

It enables, for example, individual room control units or building man-
agement systems to be directly connected to Vitotronic control units.
Further information can be found in the LON manual; see
www.viessmann.de\lon.
