THERMASREG
Electronic frost protection thermostat ⁄ frost monitor THERMASREG
copper, additional control input 0 -10 V and summation output 0 -10 V, optional with or without display. The frost sensor is used for monitoring air
conditioning systems, heat exchangers, heating registers and similar equipment preventing frost damage and freezing up. The sensor can detect when
the temperature falls below the limit value at the coldest measuring point of the capillary tube. In case of capillary breakage, power failure, or electrical
damage at the device, the frost protection monitor's relay automatically switches to frost. Mounting clamps MK-05-K are included in the delivery.
