THERMASREG
The mechanical frost protection thermostat ⁄ frost monitor THERMASREG
reset, or with mechanical locking and manual reset, is available with capillaries in lengths of 0.6 m, 1.8 m, 3 m, 6 m, or 12 m. This frost protection
monitor is used for air- and water-side temperature monitoring at heat exchangers, water circulation systems, and heating registers to prevent
freezing up and to avoid frost damages, e. g. in ventilation and air conditioning ducts. All devices are self-secure with sensor breakage detection. In
case of damage to the capillary tube – membrane system, the relay automatically switches to heating function. FST - 3 can also be used for monitoring
liquids. The sensor tube can be installed inside an immersion sleeve. Mounting clamps MK - 05 -K are included in the delivery.
