Abstract
A method and system for providing HVAC signaling over a two-wire circuit is disclosed which also provides operating power for a thermostat. The system is relatively inexpensive to implement and produces only low levels of heat at the sender unit to avoid adversely affecting the ability of the thermostat to monitor the temperature of its surroundings.
