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 200A and Vitotrol 300A

One Vitotrol 200A or one Vitotrol 300A can be used for every heating
circuit in a heating system.
5
The Vitotrol 200A can regulate one heating circuit; the Vitotrol 300A
up to three heating circuits.
Up to two remote controls may 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 circuit
with mixer.
Note
Hardwired remote control units cannot be combined with the wireless
base station.
Installation site:
■ 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 sunlight, fireplace, TV set, etc.)
Connection:
■ 2-core lead, length max. 50 m (even if connecting several remote
control units)
■ Never route this lead immediately next to 230/400 V cables
■ LV plug as standard delivery
