Abstract: An electric heating system controlled with a remote thermostat. The system may incorporate wireless technology and a line voltage equipment interface sub-system. The sub-system may have a line voltage relay and an antenna. The relay may be mounted within an electric heater enclosure. The antenna may be mounted directly on the enclosure. The antenna may receive temperature control signals from a transmitter of the thermostat. The signals may be processed to control a connection of the heater to power with a relay receiving the processed control signals. The control of power to the heater may maintain a temperature approximately equal to a thermostat temperature setting. The antenna and relay electronics may provide a backup control of the heater in the event of, for example, a loss of signals from the thermostat. The backup control may prevent the temperature proximate to equipment interface sub-system from approaching a freezing point.
