This achieves a high switching point accuracy. Long-term stability: With a maximum switching point deviation of +/- 5% over a lifespan of 250,000 switching cycles, the thermostat is ideally suited for precise long-term use. Environmentally friendly: The environmental friendliness of the JUMO heatTHERM is ensured by a cadmium-free design and RoHS compliance. Energy-saving: Without the need for additional auxiliary energy during temperature measurement, the electromechanical thermostat offers a significant advantage. Applications: Regulation and monitoring of thermal processes, e.g., in open and closed heating systems and in steam boilers.
