Temperature sensors with water
temperature sensor and integrated
overheating protection
The water temperature sensor captures the coolant
temperature at the heat exchanger outlet as electrical
resistance.
This signal is transmitted to the control unit, where it is
processed.
The overheating protection integrated into the tempera-
ture sensor is responsible for temperature limitation.
Similar to the water temperature sensor, the coolant
temperature is captured at the heat exchanger outlet as
electrical resistance and transmitted to the control unit.
Overheating protection prevents inadmissibly high heater
operating temperatures.
At a temperature greater than 135°C heater deactivation
and interlocking is initiated.
It is not necessary to manually reset the overheating
protection.
