A system and a method are provided for returning oil in a heating, ventilation, and air conditioning (HVAC) system by determining when an ambient zone temperature is equal to or less than a temperature limit and reversing a direction of refrigerant flow of the HVAC system based on the length of time. Also, a system and a method are provided for monitoring the length of operation in a first and a second heating mode and for reversing a direction of refrigerant flow based on the length of time operation occurs in the first and second heating modes. A system and a method having a first compressor, a first heating mode, a second heating mode, a defrost mode, and a controller is disclosed. The controller selectively controls initiation of the defrost mode in response to an HVAC system operating in a heating mode of operation for a predetermined amount of time.

System and Method for Oil Return in an HVAC system

A system and a method are provided for monitoring a condition and selectively executing a certification defrost algorithm for a heating, ventilation, and air conditioning (HVAC) system in response to the status of the monitored condition. A system and a method are provided for selectively operating a certification defrost algorithm in parallel to a field defrost algorithm. A system and a method are also provided for causing a controller to execute a first algorithm and for causing the controller to selectively execute a second algorithm while also executing the first algorithm where each of the first algorithm and the second algorithm are configured to selectively cause the HVAC system to operate in a defrost mode.

A system and method is provided for monitoring a system pressure to infer whether a high pressure cut out (HPCO) switch has opened disabling a heating, ventilating, and air conditioning (HVAC) compressor. A system and method are also provided for determining whether to disable the heating, ventilating, and air conditioning (HVAC) compressor based on a status of a low pressure cut out (LPCO) switch, an ambient temperature, and system mode state. The systems and methods may be used interchangeably with the appropriate adjustments to decision limits, such as where the LPCO may be monitored to infer status and the HPCO status may be directly used with temperature and system mode state.

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.

Device and method for recording air conditioning system information

A system and a method are provided for powering up a heating, ventilation, and air conditioning (HVAC) system and operating a sump heater for a compressor for a first predetermined period of time in response to the HVAC system being powered up. A heating, ventilation, and air conditioning system and a method for controlling the system are provided. The HVAC system includes a compressor, a sump heater associated with the compressor, and a controller configured to control the compressor and the sump heater so that the sump heater is not operated while the compressor is operated.

An anti-theft vehicle subsystem disabling device including a digital controller and one or more remote receiving vehicle subsystem interface units for randomly simulating problematic vehicle behavior. The system determines user authorization based on keycode entry of either a master code or a programmable user code. Once authorized all vehicle subsystems under control operate normally. While authorized, the system also allows optional entry into a valet mode and constantly monitors a hidden anti-hijacking button. Any time unauthorized use is determined, the digital controller randomly generates a unique controlling signal with random timing variations that is communicated to the remote receiving subsystem interface units. These units can be connected in series with vital vehicle subsystem components in order to interfere with typical subsystem component operation, thereby inducing the illusion of an actual vehicle problem severe enough to inhibit vehicle driveability. This system allows unique implementation by locating disabling receivers on any variety of vital vehicle subsystems, presenting thieves with multiple unknowns specific to each vehicle. Due to this, in addition to the random nature of the device, there is no chance for a pattern to develop, and therefore very little possibility that the device will be recognized by an unauthorized operator.

A combination drinking cup and lid for liquid. A cup has a continuous, substantially cylindrical wall and a substantially circular opening at a longitudinal end of the cylindrical wall. A removable lid for closure of the opening has an edge mating with the circular opening of the cup. A spout is located near the circumferential edge of the lid and a weight is located near the circumferential edge radially opposed from the spout. When the cylindrical wall rests on a surface, the force of gravity will radially rotate the cup and the lid so that the weight will rotate towards the surface and the spout will rotate away from the surface.
