Publication number: 20080059833Abstract: A control panel for an HVAC unit is disclosed. The control panel includes a memory device storing a predetermined reset code that corresponds to a plurality of control signals and which memory device is configured to store a plurality of fault codes resulting from faults occurring during operation of the HVAC unit. The control panel also includes a plurality of terminals capable of receiving control signals from a source external the control panel and a processing unit configured to compare control signals received from the plurality of terminals to the predetermined reset code and further configured to erase the stored fault codes in the memory device in response to a determination that the received control signals match the predetermined reset code.Type: ApplicationFiled: November 5, 2007Publication date: March 6, 2008Applicant: JOHNSON CONTROLS TECHNOLOGY COMPANYInventor: Gregory Harrod

Publication number: 20070116442Abstract: A heating arrangement is provided for use in an air handling unit. The heating arrangement includes at least one heating device to be disposed in the airflow of an air handling unit. A base is configured to support the at least one heating device and a first guide member to be mounted on a structural component inside the air handling unit. A second guide member is mounted on the base, the second guide member being configured to slidably engage the first guide member. Sliding engagement of the first guide member and the second guide member positions the at least one heating device to an installed position inside the air handling unit.Type: ApplicationFiled: November 22, 2005Publication date: May 24, 2007Applicant: YORK INTERNATIONAL CORPORATIONInventors: Gregory Harrod, Bennie Hoyt, Cosimo Caronna, Elmer Romero

Publication number: 20060196202Abstract: An HVAC system and method for configuring a controller to control a compressor including a detection system provided to determine a type of compressor. The detection system includes a processor; and a load sensing circuit connected between the processor and a controller. The controller has a plurality of output connections connectable to a compressor. The load sensing circuit senses whether a load is present on each output connection of the plurality of output connections and provides a load signal to the processor indicating whether a load is present on each output connection. The load signals are processed with the processor to determine the type of compressor is present. The controller is configured to control the compressor in response to the determined type of compressor.Type: ApplicationFiled: January 6, 2006Publication date: September 7, 2006Applicant: YORK INTERNATIONAL CORPORATIONInventors: Gregory Harrod, Jeffrey Tucker

Publication number: 20060196200Abstract: A method for configuring a controller for an HVAC system. The method comprises providing a closed loop refrigerant system and a control system to control the closed loop refrigerant system. The control system comprises a controller, an input device, and a processor including a signal sensing circuit. The input device is activated to provide one or more signals to the controller to control the components of the closed loop refrigerant system. One or more signals are sensed with the signal sensing circuit to determine whether signals are present between the input device and the controller. The signals are processed with the processor to determine what type of closed loop refrigerant system is present. The controller is then configured to control the type of system determined by the processor.Type: ApplicationFiled: January 23, 2006Publication date: September 7, 2006Applicant: York International CorporationInventors: Gregory Harrod, Jeffrey Tucker

Publication number: 20060122733Abstract: A heating control method is provided for a multi-stage heating system including a heating circuit having a compressor, a condenser and an evaporator. An auxiliary heater is provided that is selectively controlled independently of the heating circuit. During a heating cycle in which the ambient outside temperature is greater than the balance point temperature associated with the operation of the heating circuit, the auxiliary heating circuit is normally prevented from operating. However, if the heating requirements are not satisfied after a predetermined time or the compressor is non-functional or operating improperly, the auxiliary heater is enabled.Type: ApplicationFiled: January 27, 2006Publication date: June 8, 2006Applicant: YORK INTERNATIONAL CORPORATIONInventors: Gregory Harrod, Jeffrey Tucker
