Two thermostats in one casing:
   Tamper-proof (Pre-set) Thermostat/Contact breaker (NC) for regulating heaters or for switching signal devices when temperature has fallen below the minimum value. The contact opens when temperature is rising.
   Tamper-proof (Pre-set) Thermostat/Contact maker (NO) for regulating filter fans, heat exchangers or for switching signal devices when temperature limit has been exceeded. The contact closes when temperaure is rising.
   Heaters and cooling equipment can be switched independently from each other with a temperature offset as opposed to the usual change-over contacts.
