Abstract
A system for smart HVAC controllers that is capable of automatically detecting and handling all HVAC control wires, whether the HVAC system is a single or dual transformer system. The system comprises a channel selector for selecting the various channels of an HVAC system for detection, one or more voltage and current limiters for conditioning channel signals for input to a microcontroller unit, a microcontroller comprising an intelligent detection algorithm for operating the channel selector and detecting and handling channel signals, and a one-way gate for protecting against damage from connection of two transformers during wire detection.
