Honeywell Freeze Stat Refrigeration Controller

The L482A Low Limit Controller provides temperature or limit control of air conditioning systems by operating electric motors for dampers, valves, compressors, or fans. It responds to the lowest temperature to which any one-foot portion of the 20 ft., temperature-sensitive element is exposed. It can be used to close electrically operated dampers, open electrically operated valves or to shut off compressor or fan motors when the element senses temperatures below a critical point. The L482A can also act as a frost alarm sensor in storehouses or other locations where low temperatures would damage building contents. Used to limit or control temperature in air conditioning systems or refrigerated enclosures. L482A has a manual reset.
