Universal capillary double thermostat, TW 0…120 °C, TW 0…120 °C, hysteresis 2x 3 K
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. Thermowells/protective coils are not included in the scope of delivery. The JZ-30 accessory must be used in conjunction with thermowells or protective coils.
The control range / hysteresis for both temperature monitors is 0…120 °C / 3 K.
