Thermostat de sécurité 85 °C De Dietrich JJJ030006939

The Limit Thermostat 85°C is a safety device that monitors water temperature in boilers and heating systems. When the temperature reaches 85°C, the thermostat opens its contacts to interrupt the burner operation, preventing overheating and potential damage. This component is essential for safe boiler operation and is often replaced when the system fails to shut off at the correct temperature or when error codes indicate a thermostat fault. It ensures your heating system operates within safe thermal limits.
