11.1 Sensor curves

DANGER: Risk to life from electric shock.
▶ Isolate the heating system before taking any readings.
Fig. 65 Sensor curves: boiler sensor
Resistance in 
[x]
[y] Temperature in °C
Two identical sensors (dual sensors) installed in one
sensor casing are used as boiler sensors.
All temperature sensors on the GB402 have the same
sensor curve.

Always measure the temperatures being compared (room, flow, outside
and flue gas temperatures) near the relevant sensor. The curves depict
mean values and are subject to tolerances. Measure the resistance at the
cable ends.
