Thermostat N/O + N/C

This dual adjustable temperature thermostat, ETR203, for any enclosure, houses two independent thermostats, which reduces space requirements within the enclosure. One has a normally open (NO) contact, and one has a normally closed (NC) contact, which means that one thermostat's temperature setting could control cooling and the other thermostat could control heating. The devices controlled, such as a filter fan or a fan heater, will then turn on or off at the required temperature level, set by the user, which results in reduced operational cost.
