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.

Abstract: A humidifier for adding humidity to an air stream of an HVAC system includes a housing configured to be mounted to a surface of an HVAC duct. A back side of the housing may be positioned adjacent to an opening in the surface of the HVAC duct, and the housing may be configured to hold a humidifier pad in an operating position. The housing may define a first air flow path from a first side of the humidifier pad to the opening in the surface of the HVAC duct when the housing is mounted to the surface of the HVAC duct. The housing may further define a second air flow path from a second side of the humidifier pad to a bypass aperture. At least part of the second air flow path may be defined by a bypass duct member. The bypass duct member may be field-reconfigurable between at least a first position resulting in the bypass aperture being located at a first location, and a second position resulting in the bypass aperture being located at a second location.
