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.
