Tamperproof (Pre-set) Thermostat NC (normally closed): Thermostatopens on temperature rise (red module

housing) – for regulating heaters or for switching signal devices when temperature has fallen below the minimum
value.

Tamperproof (Pre-set) Thermostat NO (normally open):Thermostatcloses on temperature rise (blue module

housing) – for regulating filter fans, heat exchangers, cooling devices or for switching signal devices when
temperature limit has been exceeded.
