JV 24-PT Frostguard Thermostat

Description: The JV 24-PT Frostguard Thermostat is specifically engineered to prevent water heaters within ventilation units from freezing while also serving as a return water temperature transmitter. If the temperature falls below the preset value, the JV 24-PT initiates an alarm and shuts down the ventilation unit. Additionally, it triggers an alarm in the event of a sensor malfunction. Once the defect is rectified, the device remains in an "alert" state until the reset button is pressed or the power supply is temporarily disconnected. The JV 24-PT is compatible with Pt1000 sensors with a resistance of 1000 ohms at 0°C (TEV PT1000). The relay direction can be configured during installation to suit specific requirements.
