C wire creation system

Abstract

An HVAC system where either/both the heating apparatus or cooling apparatus are single or multistage and controlled by a thermostat capable of single or multistage operation through two connecting wires. A single control wire is repurposed to act as a “C” common wire to provide a return path for current in order to power a room thermostat. A code is transmitted via a wireless signal to a receiving microcontroller located in the HVAC heating or cooling unit. The receiving microcontroller interprets the signal and provides power, via relays, from the transformer to the appropriate terminal in the heating control thereby replacing the function of the repurposed wire. In essence, the wireless transmission in combination with a relay, replace the function of the white wire allowing it to be repurposed to a C wire. There is no possibility of a false trigger that commonly exists in shared wire systems.
