ABSTRACT:
The present invention is a diagnosis and testing system for a temperature control system which includes a communication bus, a control processor, and a service thermostat. The communication bus is coupled to substantially all of the components of the system. The control processor initiates communication between components by sending a bus address over the bus. The control processor includes an address decoder for recognizing various bus address signals, including a normal thermostat bus address and a service thermostat bus address. The service thermostat has a switch, a processor, and a bus interface unit. The switch selects the operating mode of the service thermostat, e.g. either normal or service modes. The bus interface unit communicates over the bus for the service thermostat processor. The service thermostat processor operates the service thermostat and is adapted to communicate over the bus using a bus address according to the operating mode which is determined by the switch.
