Notes regarding room temperature hook-up (RS function) for remote control units

Never activate the RS function for underfloor heating circuits (iner-
tia).
Information on the Vitotrol 200-A and Vitotrol 300-A
For every heating circuit in a heating system, a Vitotrol 200-A or
Vitotrol 300-A can be used.
The Vitotrol 200-A can regulate one heating circuit; the
Vitotrol 300-A up to three heating circuits.
5
Up to two remote controls can be connected to the control unit.

In heating systems with a heating circuit without mixer and heating
circuits with mixer, the RS function must only affect the heating cir-
cuit with mixer.
Note
Hardwired remote control units cannot be combined with the wire-
less base station.
Installation location:
■ Weather-compensated mode:
installation anywhere in the building
■ Room temperature hook-up:
the integral room temperature sensor captures the actual room
temperature and effects any necessary correction of the flow tem-
perature.
The captured room temperature depends on the installation site:
– Main living room on an internal wall opposite radiators
– Not on shelves or in recesses
– Never in the immediate vicinity of doors or close to heat sources
(e.g. direct insolation, fireplace, TV set, etc.).
Connection:
■ 2-core lead, length max. 50 m (even if connecting several remote
control units)
■ Never route this cable immediately next to 230/400 V cables.
■ LV plug as standard delivery
