Honeywell Frost Thermostat

Honeywell Frost Thermostat is a mains voltage thermostat designed to give frost protection to boilers and pipework as well as the building. When the temperature reduces to the set point, the thermostat heats the boiler to protect from frost. It should be fitted in the coldest area such as the loft or a garage so that it can respond to a rise in temperature. It is suitable for surface or switch box mounting and features a heat anticipator for close temperature control. It should not be fitted outdoors.
