This achieves high switching point accuracy. Long-term stability: 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. 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 for temperature measurement, the electromechanical thermostat offers a significant advantage. Applications: Control and monitoring of thermal processes, e.g., in open and closed heating systems and in steam boilers.
