THERMASREG® FS20-UW LCD 6M

Item No. 1102-1011-2102-030
EAN 4 251325 618784

Electronic frost protection thermostat/ frost monitor THERMASREG® FS-20 with fully active copper sensor rod, switching relay output, continuous temperature and valve output (summation output 0 -10 V), and control and cascading input (0 -10 V). 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.
