The Jumo built-in thermostat is a mechanical double thermostat designed for use in demanding conditions. With an impact-resistant housing made of high-quality plastic and a robust aluminum die-cast base, this device offers high durability. It combines the functions of a temperature controller and a safety temperature monitor (STW), allowing for precise temperature monitoring and regulation. The temperature setting is done via a setpoint adjuster, while the cutoff temperature of the safety temperature monitor can be adjusted with a screwdriver after removing the housing cover. The thermostat ensures high switching point accuracy and a reliable return to the original state after reaching the cutoff temperature. The self-monitoring function of the STW provides additional safety by interrupting the circuit in the event of damage to the measuring system.
