Ambient temperature
influence based on the
control / limit value range
When the ambient temperature on the case deviates from the calibration ambient temperature 22°C,
a switch point offset occurs.
Higher ambient temperature = lower switching point
Lower ambient temperature = higher switching point

Limit value can be set on the set point value setter after removing the case lid.
ATH-EXx-70 Limit value can be set on the set point value setter after removing the case lid.
The set point value setter must be subsequently sealed by the fitter to secure the set limit
value.
