Devices of the STW Honeywell / FEMA Series measure temperature. If the sensor temperature exceeds the set value, a snap-action switch opens, interrupting the electrical circuit. As soon the sensor temperature drops by more than 10 K, the snap-action switch again closes automatically. (Also, if the sensor tem-perature drops to below approx. -20 °C, the snap-action switch opens, but closes again automatically after the tem-perature rises again.)
Devices of the STB Honeywell / FEMA Series likewise measure temperature. If the sensor temperature exceeds the set value, a snap-action switch opens, interrupting the electrical circuit, and remains open until reset manually. (Also, if the sensor temperature drops to below approx. -20 °C, the snap-action switch opens, but closes again automatically after the temperature rises again.) To manually reset the device, the sensor temperature must drop by more than approx. 10 K.
