For room temperature hook-up, the Vitotrol 300A must be installed
in the living space (lead room).
Installation location:
■ Weather-compensated mode:
Installation anywhere 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 recesss, 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 quick heat-up at the start of the heating oper-
ation (if suitably encoded).
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
