THERMASREG ®
Electronic frost protection thermostat ⁄ frost monitor THERMASREG
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 from frost damages and freezing up. Falling below the limit value at
the coldest measuring point of the capillary tube is detected. 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.
