Information regarding room temperature hook-up (RS function) for remote control units
Due to the "inertia" of underfloor heating systems, the RS function
should not be applied to an underfloor heating circuit.
The RS function must only affect the heating circuit with mixer.
Information regarding the Vitotrol 200A and 300A
Vitotrol 200A and 300A may be combined in a single heating sys-
tem.
The Vitotrol 200A can regulate one heating circuit, the Vitotrol 300A
up to 3 heating circuits.
Vitotrol 200A
Part no. Z008 341
KM BUS subscriber
A Vitotrol 200A can be used for each heating circuit in a heating sys-
tem. Up to 2 remote controls may be connected to the control unit.
Functions:
■ Display of room temperature, outside temperature and the operating
condition.
■ Setting the standard room temperature (day temperature) and oper-
ating program via the standard display.
Note
The reduced room temperature (night temperature) is set at the con-
trol unit.
■ Party and economy mode can be enabled via keys
■ Only for heating circuit with mixer:
Room temperature sensor for room temperature hook-up
Note
For room temperature hook-up, the Vitotrol 200A must be installed
in the living space (lead room).
Installation location:
■ Weather-compensated mode:
Installation at any point in the building.
■ Room temperature hook-up:
Installation in the main living room on an internal wall opposite radi-
ators. Never install inside shelving units, in recesses, or immediately
by a door or heat source (e.g. direct sunlight, fireplace, TV set, etc.).
The integral room temperature sensor captures the actual room
temperature and effects any necessary correction of the flow tem-
perature as well as a rapid heat-up at the start of the heating oper-
ation (if suitably encoded).
