Low voltage power line communication for climate control system
First Claim
1. A climate control system comprising:
- an alternating current low voltage transformer that conducts a low-frequency low-voltage waveform across hot and common power transmission lines;
a thermostat controller, a controller for a heating system, and at least a controller for a compressor of a heat pump or air conditioning system, the thermostat controller, heating system controller and compressor controller being connected to each other only through each controller'"'"'s individual connection to the hot and common power transmission lines;
wherein each of the individual thermostat, heating system and compressor controllers are configured to recognize a command that is unique to the specific thermostat, heating system controller or compressor controller, which unique command will only request operation of the specific controller, and each controller is capable of transmitting one or more signals that are superimposed onto the low-frequency low-voltage waveform and include information identifying a destination controller that the signals are intended for.

Abstract
A system for controlling one or more components of a climate control system is provided that includes one or more controllers in connection with low voltage power lines for powering the one or more controllers. The controllers are further capable of transmitting one or more communication signals via the low voltage waveform. The system includes a thermostat controller, at least one system controller for a heating or cooling system, and a controller for a circulating air blower. The thermostat controller, system controller and circulating air blower controller are connected to each other only through each controller'"'"'s individual connection to the hot and common low voltage power transmission lines. Each controller is capable of transmitting one or more signals that are superimposed onto the low-frequency low-voltage waveform and include information identifying a destination controller that the signals are intended for.
