An HVAC actuator configured to actuate an HVAC component may include a rotatable output shaft having a range of rotation between a first end position and a second end position, a drive mechanism configured to selectively drive the output shaft, and a housing for housing the drive mechanism. The HVAC actuator may include a position indicator viewable from a front side of the housing that moves as the output shaft is rotated such that the position indicator indicates a current position of the output shaft. The position indicator may include an indicator wheel that is directly coupled to the output shaft of the HVAC actuator and may rotate with the output shaft. The indicator wheel may have one or more markings that move with the indicator wheel. The one or more markings may include a line extending in a radial direction from a rotation axis of the indicator wheel.

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.

An HVAC actuator may include a rotatable output shaft, a drive mechanism configured to selectively drive the output shaft, two or more wiring terminals, and a removable blocking tab configured to block wire attachment to at least one of the two or more wiring terminals. When the removable tab is removed, wire attachment to the previously blocked at least one wire terminals may no longer blocked. The removable block tab may be a break-away tab. The HVAC actuator may include a housing enclosing the drive mechanism, and the break-away tab may be integral to the housing. In some instances, the removable tab, once removed, is not configured to be reattached, but this is not required.

An illustrative electronic assembly includes a housing and a wall plate, where the wall plate is releasably connectable to the housing. The housing and the wall plate may be configured such that the housing and the wall plate may be able to initially engage each other with the wall plate misaligned relative to the housing. The housing and the wall plate may be configured to guide one another into alignment as the housing and the wall plate are moved together.

A mount for mounting an ultraviolet (UV) lamp assembly or other device to a duct wall of an HVAC system. The mount may have a base having a first side and a second side, an aperture extending through the base from the first side to the second side, one or more first mounting features, and one or more second mounting features. To secure a UV lamp assembly to the base, the mount may have a socket allowing at least a portion of the UV lamp to extend through the aperture of the base. To secure the first side of the mount to the duct wall, the first mounting features receives connectors. To secure the second side of the mount to the duct wall, the second mounting features receive connectors. A recess between the second mounting features may facilitate connecting connectors to a duct wall without the duct wall interfering with the secured UV lamp assembly.

Thermostat housing

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. In some cases, the first and second locations are on the left and right sides, respectively, of the humidifier housing.
