ALRE JTF Thermostat

The JTF is a fail-safe frost protection thermostat. The device has been specially designed for anti freezing protection purposes. It detects the temperatures in air or water flows around or inside of warm water heating spirals and heat exchangers in ventilation-, heating- and/or air conditioning systems and triggers the corresponding control commands. With this thermostat, the adjusted set value can be protected against misadjustment by applying a lead seal. All devices of this series have been tested and certified by the TÜV (Association for Technical Inspection) in compliance with DIN EN 14597
