Abstract

The disclosure provides an auxiliary controller of a HVAC system, a method of manufacturing a HVAC system, a method of starting a HVAC system and a HVAC system. In one embodiment, the HVAC system includes: (1) a main system controller having a main non-volatile memory and configured to direct operation of the HVAC system and store main controller application information associated therewith on the main non-volatile memory (2) an auxiliary controller having (2A) an interface coupled to the main system controller and configured to communicate therewith, (2B) a processor, coupled to the interface and configured to direct the operation of a component of the HVAC system and (2C) an auxiliary non-volatile memory configured to receive a copy of the main controller application information via the interface and store the main controller application information thereon.

Claims

1. An auxiliary controller of a heating, ventilating and air conditioning (HVAC) system, comprising:

an interface coupled to a main system controller of said HVAC system and configured to communicate therewith, said main system controller having main controller application information stored thereon;

a processor, coupled to said interface and configured to direct the operation of an auxiliary component of said HVAC system, wherein said auxiliary component is one of a plurality of HVAC components in said HVAC system; and

a non-volatile memory configured to receive a copy of said main controller application information via said interface and store said main controller application information thereon.

2. The controller as recited in claim 1 wherein said main controller application information includes model identification data or model specific data for said main system controller.

3. The controller as recited in claim 1 wherein said main controller application information includes application specific data for said main system controller.

4. The controller as recited in claim 1 wherein said auxiliary controller is an indoor blower motor controller for said HVAC system.

5. The controller as recited in claim 1 wherein said interface is configured to receive said main controller application information from said main system controller during manufacturing.
