1.Features:

Adjustable temperatureSmall hysteresisEasy install,clip fixingHigh switching capacity 

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.Functionality: The temperature setting on the scale equals to the upper switch point, which means that the Normally Closed contact opens. The temperature setting minus switch temperature difference (and tolerances) equals to the lower switch point, which means that the Normally Closed contact closes.

*Connecting terminal "N" (RF heating resistor) causes the thermal feedback to work and allows for a possible reduction of the switch temperature difference. Thermal feedback is subject to surrounding conditions and thus has to be determined for each individual application.
