Duct frost protection thermostat-THERMASREG® FST-K

Mechanical frost protection thermostat ⁄ frost monitor THERMASREG® FST-K with switching output, duct tube monitored across the entire length, with automatic reset or with mechanical locking, with / without optional manual reset. The frost protector is suitable for air or water-side temperature monitoring at heat exchangers, water circulation systems and heating registers to prevent freezing up and to avoid frost damage, e.g. in ventilation and air conditioning ducts. The FST-K is intrinsically safe and is equipped with sensor breakage detection. In the event of damage to the capillary membrane system, the frost sensor automatically switches to the heating function. The scope of delivery includes the mounting flange MF-14-K.
