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.

Abstract: An HVAC controller includes a first input terminal configured to be electrically coupled with a first field wire and a second input terminal configured to be electrically coupled with a second field wire, and a double pole relay including two input terminals and two output terminals. Control circuitry is operably coupled to the temperature sensor and the double pole relay and is configured to determine whether the first field wire is electrically coupled with the first input terminal and whether the second field wire is electrically coupled with the second input terminal.

Abstract: A thermostat assembly includes a thermostat and a trim ring.

The trim ring includes an outer surface that transitions from a larger back side profile to a smaller front side profile. A front side of the trim ring includes a thermostat recess that is configured to receive at least part of the back portion of the thermostat.

Abstract: A filterwell cartridge holder having a face for compressible engaging pleats on a water filter cartridge and a further face holding a dispensing cartridge thereon in a position to release dispersants into a filterwell containing a water filter cartridge.

Abstract: A filterwell cartridge holder mountable within a hot tub filterwell with the filterwell cartridge holder having a handhold on one end and a feed pipe connector on an opposite end that is attachable to or removable from a filterwell feed pipe with the filterwell cartridge holder engaging and supporting dispensing cartridges thereon to maintain the dispensing cartridges in a dispensing mode within the filterwell.

Abstract: An illustrative damper system includes a damper blade that is configured to be positioned within a duct, such as a bypass duct of an HVAC system. A shaft is in communication with the damper blade, and an actuator or force adjustment mechanism is in communication with the shaft. The actuator or force adjustment mechanism may include a housing and a spring therein, where the spring is in communication with the shaft. The shaft, the damper blade, and the spring may be configured such that the shaft may affect movement of the damper blade about a rotation axis offset from a diametrical axis of the damper blade.

Abstract: An HVAC controller that monitors a current performance level of an HVAC system, and determines if the current performance level falls below a minimum performance threshold level for at least a first predetermined amount of time. The HVAC controller may be configured it display an alert on the display of the HVAC controller if the HVAC controller determines that the current performance level has fallen below the minimum performance threshold level for at least the first period of time. In some cases, the HVAC controller may remove the alert from the display of the HVAC controller if the current performance level subsequently rises and remains above the minimum performance threshold level for at least a second predetermined amount of time. In some cases, the first predetermined amount of time may include a utility shutoff period component and/or a defrost cycle period component.

Abstract: A filterwell cartridge having ports for dispensing a dispersant directly into a filterwell of a hot tub, spa or the like with the filterwell cartridge peripherally and postionally supportable in a quick release mode through facial engagement of compound surfaces located on opposite sides of the filterwell cartridge.

Abstract: An illustrative damper system includes a damper blade that is configured to be positioned within a duct, such as a bypass duct of an HVAC system. A shaft is in communication with the damper blade, a torsion spring is in communication with the shaft, and a force adjustment mechanism is in communication with the torsion spring. The shaft, the damper blade, and the torsion spring may be configured such that the shaft may affect movement of the damper blade about a rotation axis and the torsion spring may provide a bias force to the shaft for biasing the damper blade toward a desired position (e.g. closed position).

Abstract: A wireless occupancy sensor that is configured to be deployed within a building space includes a sensor body, an occupancy sensor that is housed by the sensor body, a light emitting diode (LED) that is housed by the sensor body, a wireless transceiver that is housed by the sensor body and is configured to be in wireless communication with a remote device. A controller is housed by the sensor body and is operably coupled to the occupancy sensor, the LED and the wireless transceiver and is configured to receive via the wireless transceiver a request to illuminate the LED from the remote device and in response to receiving the request, illuminate the LED in order to help visually identify the wireless occupancy sensor in the building space.

Abstract: An HVAC controller may be programmed to identify one or more faults with respect to the operation of a connected HVAC system. In some cases, the HVAC controller may record a fault to a fault log and/or display an alert on the display of the HVAC controller only after a predetermined number of faults of the same fault type have been identified by the HVAC controller, sometime within a predetermined number of cycles of the HVAC system or within a predetermined amount of time.

Abstract: An HVAC controller is configured to log and record performance related data related to a performance of an HVAC system over a period of time in one or more performance logs stored in a memory of the HVAC controller. In some cases, the HVAC controller may be configured to retrieve at least some of the performance related data from the performance log that corresponds to a selected period of time that may be selected by a user, and display the retrieved performance related data on a display of the HVAC controller.

Abstract: An electrical connector includes a housing having contact channels with electrical contacts received therein each having a poke-in spring beam configured to engage an electrical wire when poked-in to the housing. The electrical contact is movable between a resting position when no wire is present in the wire channel and a clearance position where the electrical contact allows the electrical wire to be removed from the wire channel. Pivot levers are held by the housing and are coupled to corresponding electrical contacts with a pivot end pivotably coupled to the housing and a push button end having a push button pressed to move the corresponding electrical contact to the clearance position. When the electrical wire is loaded into the wire channel, the electrical contact is positioned in a pinching position in which the spring beam pinches against the electrical wire in physical contact with the electrical wire.
