at operation:
32ºF to 194ºF (0ºC to 90ºC)
-
when storing
or transporting:
- 4ºF to+158ºF (-20ºC to+70ºC)
Room Temperature Sensor
Separate room temperature sensor as supplement to
the Vitotrol and 300A; to be used if the 300A cannot
be installed inside the main living room or in a suitable
position where the unit can capture and adjust the
temperature.
Installation in the main living room on an internal wall
opposite radiators. Never install inside shelf units,
recesses, immediately by a door or heat source (e.g.
direct sunlight, fireplace, TV set, etc.).
Connect the room temperature sensor to the Vitotrol 300A.
Electrical connection:
-
2-wire cable with a wire size of min. AWG 18 copper
-
The cable length between the control unit, remote
control unit and room temperature sensor must not
exceed 98 ft. (30 m)
Max. ambient temp.
- at operation:
32ºF to 104ºF (0ºC to 40ºC)
- when storing
or transporting:
-4ºF to+149ºF (-20ºC to+65ºC)
Immersion Temperature Sensor
To capture the low loss temperature
Specification
