Abstract

A system controller is provided that includes a communication network for transmitting and receiving information from an installed blower motor controller, and a removable memory device connected to the system controller. The removable memory device includes stored system parameter information related to a particular heating or cooling system, which information includes at least motor related parameters related to one or more types of blower motors. The system controller further includes a processor that receives, via the communication network, identifying information from the blower motor controller that identifies the type of blower motor that is installed. The processor is configured to retrieve motor related parameters corresponding to the specific identified blower motor from the memory device, and to send the corresponding motor related parameters to the blower motor controller.

2. The system controller of claim 1 wherein said identifying information includes a manufacturer identification number associated with the type of blower motor.

3. The system controller of claim 1 wherein said identifying information includes the horsepower rating of the installed blower motor.

4. The system controller of claim 1 wherein the processor is configured to request the operation of the blower motor through the communication of one or more command signals to the blower motor controller, where each command signal includes embedded therein parameter information that is specific to the identified blower motor, which the blower motor controller utilizes in determining the requested operation.

5. The system of claim 1 wherein the system controller requests the operation of the blower motor at a particular airflow in terms of cubic feet per minute (CFM), by communicating command signals to the blower motor controller, where the command signals include embedded therein the requested CFM and parameter information that is specific to the identified blower motor, which the blower motor controller utilizes in determining the speed for establishing blower motor operation at the requested CFM.

6. The system controller of claim 1 further comprising a removable memory device connected to the system controller, on which the system-specific parameter information input to the controller is saved.

7. The system controller of claim 6 wherein the memory device on which the parameter information is stored may be removed from the system controller, to thereby retain the system-specific parameter information in the event that the installed system controller requires replacement with another system controller for any reason.

8. The system controller of claim 1 wherein the processor is configured to request the operation of the blower motor at a particular airflow in terms of cubic feet per minute (CFM), by communicating command signals to the blower motor controller, where the command signals include embedded therein the requested CFM and parameter information that is specific to the identified blower motor, which the blower motor controller utilizes in determining the speed for establishing blower motor operation at the requested CFM.

9. A system controller for controlling the operation of a heating or cooling system having a blower motor controller within the heating or cooling system, comprising:
