FZK 011 High Sensing Accuracy Mechanical Thermostat

he FZK 011 mechanical thermostat is used for controlling heating and cooling equipment, filter fans, or signal devices where a high degree of sensing accuracy is required. An integrated resistor (RF) can be connected to improve the switch temperature difference (see Option note). The thermostat senses the surrounding air temperature and can switch both resistive and inductive loads via the SPDT (change-over) contact.
