In an embodiment, the method includes querying a second unit controller that has replaced the first unit controller. In addition, the method includes determining that the second unit controller lacks personality data that is unique to the first unit. Further, the method includes transferring the personality data to the second unit controller from a memory of the climate control system that is separate from the second unit controller. ## Claims ### Claim 1 A repaired climate control system comprising: a system controller; and a first unit, the first unit including a replacement unit controller, wherein the replacement unit controller is separate from the system controller, wherein the system controller is configured to: query the replacement unit controller after it has been installed in the first unit, determine that the replacement unit controller as installed lacks personality data, transfer personality data to the replacement unit controller from a memory of the repaired climate control system that is separate from the replacement unit controller, wherein the personality data is unique to the first unit and was previously stored on a separate unit controller, and select an operational parameter for the first unit based on the personality data transferred to the replacement unit controller and additional data associated with the first unit, wherein the replacement unit controller is configured to: control the operation of the first unit, and operate the first unit based on the operational parameter selected. ### Claim 2 (depends on 1) The repaired climate control system of claim 1, wherein the first unit comprises a fan, and wherein the operational parameter comprises a speed of the fan. ### Claim 3 (depends on 1) The repaired climate control system of claim 1, wherein the first unit comprises a compressor, and wherein the operational parameter comprises a speed of the compressor. ### Claim 4 (depends on 1) The repaired climate control system of claim 1, wherein the memory is a memory of the system controller. ### Claim 5 (depends on 1) The repaired climate control system of claim 1, further comprising a second unit with a second unit controller, wherein the memory is a memory of the second unit controller. ### Claim 6 (depends on 5) The repaired climate control system of claim 5, wherein the system controller is further configured to transfer second unit personality data to the replacement unit controller, wherein the second unit personality data comprises data that is unique to the second unit. ### Claim 7 (depends on 1) The repaired climate control system of claim 1, wherein the personality data includes a serial number of the first unit, and the climate control system is coupled to a communication network configured to transmit the serial number. ### Claim 8 (depends on 1) The repaired climate control system of claim 1, wherein the additional data associated with the first unit includes a plurality of target values, and the system controller configured to select the operational parameter for the first unit is further configured to select a first of the plurality of target values based the personality data. ### Claim 9 (depends on 1) The repaired climate control system of claim 1, wherein the separate unit controller is a controller that has been removed from the first unit prior to the replacement controller being installed in the first unit. ### Claim 10 A repaired climate control system comprising: a system controller; and a first unit, the first unit including a replacement unit controller, wherein the replacement unit controller is separate from the system controller, wherein the system controller is configured to: query the replacement unit controller after it has been installed in the first unit, determine that the replacement unit controller as installed lacks personality data, and transfer personality data to the replacement unit controller from a memory of the repaired climate control system that is separate from the replacement unit controller, wherein the personality data is unique to the first unit and was previously stored on a separate unit controller, wherein the replacement unit controller is configured to: control the operation of the first unit, select an operational parameter for the first unit based on the personality data transferred to the replacement unit controller and additional data associated with the first unit, and operate the first unit based on the operational parameter selected. ### Claim 11 (depends on 10) The repaired climate control system of claim 10, wherein the first unit comprises a fan, and wherein the operational parameter comprises a speed of the fan. ### Claim 12 (depends on 10) The repaired climate control system of claim 10, wherein the first unit comprises a compressor, and wherein the operational parameter comprises a speed of the compressor. ### Claim 13 (depends on 10) The repaired climate control system of claim 10, wherein the memory is a memory of the system controller. ### Claim 14 (depends on 10) The repaired climate control system of claim 10, wherein the personality data includes a serial number of the first unit, and the climate control system is coupled to a communication network configured to transmit the serial number. ### Claim 15 (depends on 10) The repaired climate control system of claim 10, wherein the personality data includes an installation date for the first unit, and the climate control system is coupled to a communication network configured to transmit the installation date. ### Claim 16 (depends on 10) The repaired climate control system of claim 10, wherein the additional data associated with the first unit includes data stored on the replacement unit controller before it has been installed in the first unit. ### Claim 17 A repaired climate control system coupled to a communication network, the repaired climate control system comprising: a system controller; and a first unit, the first unit including a replacement unit controller; wherein the replacement unit controller is separate from the system controller; wherein the system controller is configured to: query the replacement unit controller after it has been installed in the first unit, determine that the replacement unit controller as installed lacks personality data, transfer personality data to the replacement unit controller from a memory of the repaired climate control system that is separate from the unit controller, wherein the personality data is unique to the first unit and was previously stored on a separate unit controller, the personality data comprising warranty information, the warranty information being directed to the first unit is different from warranty information directed to a second unit of the repaired climate control system, and transmit warranty information regarding the first unit via a communication network. ### Claim 18 (depends on 17) The repaired climate control system of claim 17, wherein the warranty information comprises a serial number. ### Claim 19 (depends on 17) The repaired climate control system of claim 17, wherein the warranty information comprises an installation date. ### Claim 20 (depends on 19) The repaired climate control system of claim 19, further comprising a second unit with a second unit controller, wherein the memory is a memory of the second unit controller.
