Abstract: A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. The PTAC includes a vent aperture defined in a bulkhead of the PTAC and an auxiliary fan for urging a flow of make-up air through the vent aperture. A controller is configured for obtaining a room occupancy status from an occupancy system and determining a target make-up air flow rate based on the room occupancy status. The controller operates an exhaust fan, such as a bathroom fan, to urge a flow of exhaust air through an exhaust duct at an exhaust flow rate and operates the auxiliary fan to urge the flow of auxiliary air at an auxiliary flow rate, the auxiliary flow rate being substantially equivalent to the target make-up air flow rate minus the exhaust flow rate.

Abstract: A bulkhead assembly includes bulkhead having a first surface facing a first direction and a second surface facing a second direction. The second surface is opposite the first surface. A first connector is disposed on the bulkhead facing the first direction. A second connector is disposed on the bulkhead facing the second direction.

Abstract: An conditioner appliance, including methods for operating the same, is provided herein. The air conditioner appliance may include a housing, an outdoor heat exchanger, an indoor heat exchanger, a bulkhead, an outdoor fan, an indoor fan, one or more sensors, and a substitute control board. The housing may define an outdoor portion and an indoor portion. The outdoor fan may be disposed in the outdoor portion to direct an airflow across the outdoor heat exchanger. The indoor fan may be disposed in the indoor portion to direct an airflow across the indoor heat exchanger. The one or more sensors may be mounted within the housing. The substitute control board may be operably coupled to the outdoor fan, the indoor fan, and the one or more sensors. The substitute control board may be configured to initiate a service operation.

Abstract: A packaged terminal air conditioner unit (PTAC) and methods of operating the same are provided. The PTAC includes a bulkhead having a vent aperture through which an auxiliary fan urges a flow of make-up air into the room and a vent door for controlling the flow of make-up air. A method for detecting the position of the vent door includes operating the auxiliary fan at a first power level to reach a target speed, switching the position of the vent door, and operating the auxiliary fan at a second power level to maintain the target speed. The first power level and the second power level are compared to determine whether the vent door is in the open position or the closed position, with an increased power level indicating that the door is closed and a decreased power level indicating that the door is open.
