An HVAC system includes an indoor unit, an outdoor unit, a thermostat, and a remote control device. The indoor unit comprises a first variable speed drive (VSD) to control a speed of HVAC rotary components within the indoor unit, and the outdoor unit comprises a second VSD to control a speed of HVAC rotary components within the outdoor unit. The thermostat in communication with the indoor unit and the outdoor unit comprises a communication interface, and a system controller in communication with the communication interface. The remote control device transmits a signal to the system controller to alter the speed of the HVAC rotary components, where the HVAC rotary components operate at a high speed mode which is above the preset speed limit of the respective HVAC rotary component to achieve an enhanced cooling mode.

Time-constrained control of an HVAC system

A control device includes a graphical user interface for an automated schedule. The automated schedule may include multiple schedule periods. Schedule parameters may be adjusted by selecting a portion of one of the schedule periods, for example, on a touchscreen display. The control device may be a thermostat to control temperature in a building.

System and method for configuring a schedule

A zoned HVAC system comprises an HVAC unit including a climate control system and an air mover. In addition, the system comprises a supply air duct in fluid communication with the outlet of the HVAC unit. Further, the system comprises a return air duct in fluid communication with the inlet of the HVAC unit. Still further, the system comprises a plurality of zones positioned between the supply air duct and the return air duct. Moreover, the system comprises a bypass duct extending between the supply air duct and the return air duct. The bypass duct includes an active bypass damper having an open position, a closed position, and a plurality of partially opened positions. The system also comprises a control device configured to control the position of the bypass duct.

Method of adaptive control of a bypass damper in a zoned HVAC system

A heating, ventilation, and/or air conditioning (HVAC) system includes a bypass duct configured to selectively receive a bypass airflow therethrough in response to a supply air pressure of the HVAC system and a supply air temperature of the HVAC system.
