Sensor type
Viessmann NTC 10 kΩ at
25 °C
Permissible ambient temperature
– during operation
0 to +90 °C
– during storage and transport
−20 to +70 °C
For systems with Viessmann DHW cylinders, the cylinder temperature
sensor is installed in the threaded elbow (see chapter "Specification"
of the relevant DHW cylinder and chapter "Installation accessories")
in the heating water return.
Functions
■ Switching the solar circuit pump for DHW and/or swimming pool
heating
■ Electronic limiter for the temperature in the DHW cylinder (safety
shutdown at 90 °C)
■ Collector safety shutdown
Information regarding auxiliary function for DHW heating and
suppression of reheating by the boiler
Systems with Vitotronic control units with KM BUS offer optional sup-
pression of reheating by the boiler and auxiliary function for DHW
heating.
Systems with other Viessmann control units only offer optional sup-
pression of reheating by the boiler.
For further functions, see chapter "Functions".
