Universal capillary thermostat, 20…150 °C, hysteresis -10…-15 K, TB, internal setting, external reset
This series of devices has been specially developed for use in heating technology in boiler systems or storage tanks, district heating transfer stations and heat transfer systems, in ventilation technology as supply air monitoring or as limiters for electric heating registers and for controlling and monitoring temperatures on pipes and tanks. Thermowells, protective coils and fixing set are not included in the scope of delivery. The fixing set JZ-29 must be used in conjunction with thermowells or protective coils. When used as a contact regulator (pipe mounting), the fixing set JZ-31 must be used.
