2013 Newest Room Thermostat, Mechanical Thermostat FZK011




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. 



  • High switching capacity
  • Small hysteresis
  • Terminals easily accessible
  • Clip fixing
  • Change-over contact
