Function

Heating: The preset setpoint (scale value) is equivalent to the switch-off value of the heating.

The switch-on value is lower by the amount of operating difference.

Contact 2 - 3 breaks when temperature rises to the preset value.

Cooling: The preset setpoint (scale value) is equivalent to the switch-on value of the cooling.

The switch-off value is lower by the amount of operating difference.

Contact 1 - 2 closes when temperature rises to the preset value.
