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 > Change-over contact > Clip fixing Connection diagram Heater Thermostat FZK 011 Thermostat FZK 011 e.g. Filter fan for cooling e.g. Signal device Thermostat FZK 011 Examples of connection Heater Filter fan, Cooling equipment, Signal device 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. MECHANICAL THERMOSTAT FZK 011 Art.
