*If the Normally Closed contact is used, the switch temperature difference could be reduced by connecting
terminal “N” (RF heating resistor). It causes the thermal feedback which is subject to surrounding conditions and
thus has to be determined for each individual application.

Connection diagram
The mechanical thermostat is used for controlling heating and cooling equipment, filter fans or
signal devices. The thermostat registers the surrounding air and can switch both inductive and
resistive loads via snap-action contact. Due to the integrated thermal feedback the switch
temperature difference could be reduced.Functionality: The temperature setting on the scale
equals to the upper switch point, which means that the NC contact opens. The temperature
setting minus switch temperature difference (and tolerances) equals to the lower switch point,
which means that the NC contact closes.
