Abstract:
1. An interactive system for controlling the operation of a cooling system having at least a thermostat, a controller for an indoor blower, and a controller for an outdoor condenser unit, the interactive system comprising: an indoor blower including a blower motor, a line voltage sensor, and a motor current sensor; a controller for the indoor blower motor, the blower motor controller being configured to monitor the sensed line voltage and blower motor current and establish baseline values for the sensed line voltage and sensed current of the indoor blower motor; an outdoor condenser unit including a compressor, a compressor motor current sensor, and a compressor discharge temperature sensor; a controller for the outdoor condenser unit, the outdoor condenser unit controller being configured to monitor the sensed compressor motor current and compressor discharge pressure and establish baseline values for the sensed compressor motor current and sensed compressor discharge pressure; and a local network comprising a two-wire peer-to-peer network that is connected to each of the controller for the indoor blower motor, the controller for the outdoor condenser unit, and a thermostat for providing communication between the indoor blower motor, the controller for the outdoor condenser unit, and a thermostat; wherein the thermostat is configured to include a learning mode for initiating operation periods of the compressor and blower during the day and night, to thereby speed the process of obtaining baseline parameter information for the compressor motor and blower motor.
