Via a long-distance heat line, a building is supplied with separate heat
distribution. The long-distance line is controlled upstream according to
the demand of the heating circuits. The heating circuits of the separate
heat distribution must be controlled via the Vitotrol 350.
Note
The long-distance heat line can only be used if Köb extensions are
also being used in the sub-distributor.
Adjacent building
The line to the adjacent building is controlled with weather compen-
sation via the heating circuit control unit.
An adjacent building line can be implemented using a controller mod-
ule for the adjacent building and the required controllers.
D-SUB 9 adapter
Part no. 7395 520
Adapter for connecting the data cable to the boiler.
Information on room temperature hook-up (RS function) for remote control units Vitotrol 200A and Vitotrol
300A
Never activate the RS function in the case of underfloor heating circuits
(inertia).
In heating systems that have heating circuits with and without mixers,
the RS function must only affect the heating circuits with mixers.
Information on the Vitotrol 200A and Vitotrol 300A
One Vitotrol 200A or one Vitotrol 300A can be used for every heating
circuit in a heating system.
The Vitotrol 200A can regulate one heating circuit; the Vitotrol 300A
up to three heating circuits.
No more than two Vitotrol 200A or one Vitotrol 300A can be connected
to the control unit.
