A damper assembly is configured for placement within a duct of a ductwork system that supplies conditioned air through a register boot to a register vent. The damper assembly includes a damper that is configured to articulate from a deployment configuration, which facilitates advancement of the damper through the register boot and into the duct, to an operational configuration, in which the damper is positioned within the duct and able to selectively control how much conditioned air being supplied through the duct is permitted to pass by the damper and exit the register vent. The damper assembly includes an elongated deployment member that extends from the damper and is configured to facilitate advancement of the damper through the register boot and into the duct.

Retrofit damper assembly

A control module configured to control operation of a damper assembly includes an air damper configured to be disposed within an air duct and movable between an open end position and a closed end position, the air duct providing conditioned air to a register boot proximate the air duct. The control module includes a control module housing that is securable to the register boot. A controller is disposed within the control module housing and is configured to generate damper position control signals, the controller providing the damper position control signals to the damper assembly via a control cable that operably couples the control module with the damper assembly. An antenna extends from the control module housing and is operably coupled to the controller, and is configured to extend through an opening formed within a wall of the register boot to be positioned exterior to the register boot.

Damper system control module

A damper system is configured for installation in ductwork including a duct supplying conditioned air through a register boot to a register vent. A damper is movable between a closed position and an open position. A control module includes a control module housing, a controller, a power supply and a transceiver. The controller monitors a remaining energy level of the power supply and transmits a first low battery message via the transceiver when the remaining energy level drops to a first energy threshold. The controller instructs the damper assembly to move to a predetermined position and to transmit a second low battery message via the transceiver when the remaining energy level drops to a second energy threshold.

Retrofit damper system with power management

A modular damper system is configured for installation in a ductwork of a building that supplies conditioned air through a register vent of the building and includes a damper unit, a control module and a power module. The damper unit is mountable upstream of the register vent and includes a damper that is movable between a closed position and an open position. The control module includes a controller that provides control commands to the damper unit and includes a housing that is configured to be secured to the ductwork at a position between the register vent and the damper unit. A power module is electrically coupled to the control module to provide power to the control module and includes a housing that is configured to be secured to the ductwork at a position between the register vent and the damper unit.

Modular retrofit damper system

A damper assembly for use in a round forced air duct feeding a register vent through a register boot includes a damper frame having a frame periphery with a first side and a second side that is at least substantially parallel with the first side, the first side and the second side each having a length that is greater than a distance between the first side and the second side. A damper blade is pivotable relative to the damper frame about an axis of rotation, at least substantially parallel with the first side and the second side, between an open position and a closed position. A flexible outer seal extends outwardly from the frame periphery of the damper frame and is at least substantially circular in order to seal against an inner surface of the round forced air duct.

Damper system control module with radio controller antenna for installation

A damper assembly is configured for deployment in a forced air duct that supplies conditioned air through a register boot to a register vent secured relative to the register boot. The damper assembly includes a damper unit and a deployment strap. The deployment strap includes a first end secured relative to the damper unit and an opposing second end and has a length that is sufficient to position the damper unit in the forced air duct when the second end of the deployment strap is secured relative to the register boot. When in a deployment configuration, the damper unit has a reduced profile to facilitate deliver of the damper unit through the register boot and into the forced air duct. When in an operational configuration, the damper unit is configured to operate a damper blade between a closed position and an open position.

Retrofit damper with pivoting connection between deployment and operational configurations

A damper assembly is configured for deployment in an existing forced air duct that supplies conditioned air through a register boot to a vent cover secured relative to the register boot. The damper assembly includes a damper frame having an at least substantially obround shaped frame periphery and a damper blade having an at least substantially obround shaped blade periphery. A damper insert arm is biased into a deployment configuration in which the damper insert arm is at least substantially perpendicular to the damper frame and is movable into an operational configuration in which the damper insert arm is at least substantially parallel with the damper frame. A latch is configured to releasably engage the damper insert arm in order to hold the damper insert arm in the deployment configuration.

A wireless sensor assembly includes a wall plate that is configured to be secured to a wall of a building using either a threaded fastener or a releasable adhesive strip, the wall plate including an aperture therethrough for accommodating the threaded fastener and a recess on a back surface of the wall plate to accommodate at least part of the releasable adhesive strip. The wireless sensor assembly includes a sensor housing including a front housing region and a back housing region, the back housing region configured to be releasably secured to the wall plate, the back housing region including a recess that is configured to receive at least part of the wall plate when the back housing region is releasably secured to the wall plate.

Hydronic zone controller

An HVAC device includes a housing and a conduit tube that defines a lumen into the housing. The conduit tube and/or housing are configured such that rotating the conduit tube relative to the housing changes the direction that an outlet of the conduit tube faces. This may promote easier installation and/or maintenance of the HVAC device in the field, especially in cramped and/or poorly illuminated areas.
