摘要:
An HVAC control system has a first system controller associated with a first HVAC system and configured to control the first HVAC system and a second system controller associated with a HVAC system and configured to control the second HVAC system wherein the first system controller is selectively operable to control the second HVAC system. A method of controlling multiple HVAC systems includes providing a first HVAC system which may include a required first system controller, providing a second HVAC system which may include a required second system controller, and enabling wireless communication between the first system controller and the second system controller.

HVAC apparatus is configured to include a control system with a controller which may be connected directly to a personality module for transferring information stored in the controller related to historic operating conditions of the apparatus to the module, or information may be transferred to the controller from the module to configure the controller for operation of the apparatus at selected operating conditions of temperature, pressure and blower motor speed, for example. The personality module includes a memory circuit and a connector for releasably connecting the module to the control system of the apparatus for transferring information between the module and the controller.
摘要:
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.
