This achieves a high switching point accuracy. With a maximum switching point deviation of +/- 5% over a total lifespan of 250,000 switching cycles (TR, TW), the thermostat is ideally suited for precise long-term use. The environmental friendliness of the heatTHERM is ensured by a cadmium-free design and RoHS compliance. Without the need for additional auxiliary power for temperature measurement, the electromechanical thermostat offers a significant advantage. Applications: Control and monitoring of thermal processes, such as in open and closed heating systems or in steam boilers.
