Abstract
A method for adjusting an economic balance point in a dual fuel HVAC system includes a furnace, a heat pump and a control system. The method comprises providing a control device having a preprogrammed algorithm for controlling the HVAC system, providing a communication path between the control device and at least one component of the HVAC system, and accessing current fuel cost data; determining an economic balance point temperature based on the current fuel cost data; and updating the economic balance point temperature in the preprogrammed algorithm to adjust an actual balance point of the HVAC system.
