¹ 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 determi
ned
for each individual application.
² When connecting with wires, wire end ferrules must be used.
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 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.
> Adjustable temperature
> High switching capacity
> Small hysteresis

Important note: The contact system of the regulator is subjected to environmental influences, thus the contact resistance may
change. This can lead to a voltage drop and/or self-heating of the contacts.
