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 temperatures = lower switching point
Lower ambient temperature = higher switching point
