Room temperature sensor for supply air heating via
ventilation heating circuit A1/HC1 ("Enable reheater
bank hydraulic 7D02" set to "1").
The room temperature sensor is required in the follow-
ing cases:
Weather-compensated control unit with room tem-
■
perature hook-up ("Room temperature hook-up
200B" set to "1", "2" or "3")
■ Room temperature-dependent control unit

■ With central heating via the set heating circuit, the
bypass is not activated for passive cooling.
This prevents the heat supplied via the heating cir-
cuit being routed outside via the bypass of the venti-
lation unit.
■ Vitovent 200-C and Vitovent 300-F only:
With room cooling via the set heating/cooling cir-
cuit, the bypass is not activated for passive heating.
This prevents the heat drawn off via the heating/cool-
ing circuit being reintroduced from outside via the
ventilation unit bypass.
Note
Passive heating is not available for the other ventila-
tion units.
Additional conditions where passive heating or cooling
is not switched on: See chapter "Passive heating" and
"Passives cooling" in the "Function description".
