Important note: The contact system of the regulator is subjected to environmental influences, thus the contact resistance may change. This can lead to a voltage drop and/or self-heating of the contacts.

Suitability of this product for its intended use and any associated risks must be determined by the end customer/buyer in its final application. The ST 011 thermostat is an SPST regulator with small hysteresis. The housing design ensures optimized air circulation around the sensor element. Thermostat NC (normally closed): Thermostat opens on temperature rise (red thumbwheel) – for regulating heaters or for switching signal devices when temperature has fallen below the minimum value. Thermostat NO (normally open): Thermostat closes on temperature rise (blue thumbwheel) – for regulating filter fans, heat exchangers, cooling devices or for switching signal devices when temperature limit has been exceeded.
