Installation – Vitotronic 100, GC1
Connection of the boiler temperature sensor
The sensor measures the boiler water
temperature of the boiler.
The boiler temperature sensor is
installed at the same time as the boiler
insulation.
Check the sensor
1. Disconnect plug § in the terminal
compartment of the boiler control.
2. Measure resistance of sensor at
terminals ”1” and ”2” of the plug.

3. Compare the value measured with
the current temperature. If the value
differs significantly, check
installation and, if necessary, replace
sensor.
