An HVAC controller may be configured to control any of a variety of different types of HVAC systems that may include any of a variety of different HVAC components. The HVAC controller may be configured to solicit inputs from an installer or other user that enables the HVAC controller to help prioritize installer setup parameter settings for the HVAC controller to properly control the particular HVAC equipment that is present at the installation.

A ventilating system includes a main housing defining an inlet configured to receive air into the main housing and an outlet configured to allow the air to exit the main housing. The system further includes a fan in the main housing and configured and arranged to generate a flow of air into the main housing through the inlet and from the main housing through the outlet. The system further includes a grille configured to be coupled to the main housing, a plate configured to be coupled to the grille, and a lens coupled to the plate.

A support assembly for a heating, ventilation, and/or air conditioning (HVAC) system includes a bracket comprising a base and an arm extending from the base. The arm includes a flange having a plurality of connectors configured to facilitate coupling to a clamp at each of a plurality of positions along the arm. The arm is configured to engage with and support a conduit of the HVAC system via the clamp.

A low profile shaft adaptor for coupling an output drive member of an HVAC actuator with an input drive member of a valve. The shaft adaptor may include a clamp for selectively clamping onto the input drive member of the valve, a drive interface configured to form an interference fit with an output drive member of the HVAC actuator, and a bracket configured to mechanically couple the drive interface and the clamp such that rotational movement of the drive interface by way of the interference fit with the output drive member of the HVAC actuator causes corresponding rotational movement of the clamp and thus the input drive member of the valve.

A process for air sealing penetrations in a building which includes locating a group of penetrations and covering the penetrations with an air sealing material.

An air conditioner includes: a stepped portion provided on a side of an outlet of an air passage wall; an air passage extension having a rotary shaft in the outlet, the air passage extension being rotatable in an opening direction about the rotary shaft to bring a rear end into abutment with the stepped portion in such a manner that the air passage extension integrates with the air passage wall to form a curved surface of a predetermined curvature; and a rotary mechanism configured to cause the air passage extension to rotate in such a manner as to bring the rear end into abutment with the stepped portion when the air conditioner is put into operation.

A monitoring system is disclosed for a heating, ventilation, or air conditioning (HVAC) system of a residential or commercial building. The monitoring system includes an evaporator unit device including a first current sensor that measures current supplied to a circulator blower. The measured current from the first current sensor is used to diagnose a problem with the circulator blower. The monitoring system includes a first temperature sensor that measures refrigerant temperature between a condenser and an expansion valve. The monitoring system includes a second temperature sensor that measures refrigerant temperature between an evaporator and a compressor. The monitoring system includes a condenser unit device that communicates with the evaporator unit device. The condenser unit device includes a second current sensor that measures current supplied to the compressor. The evaporator unit device transmits sensor data to a remote monitoring service over a data network.
