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.

Abstract: Controllers for controlling heating, ventilating, air conditioning, and cooling (HVAC) systems are provided. The controllers include graphical user interfaces for user adjustment of system settings. The graphical user interfaces also may be designed to present information that facilitates user understanding of system operations. In certain embodiments, the controllers may allow users to adjust balance point and/or LTCO temperature values. In these embodiments, the graphical user interfaces may include slide bars for adjusting the balance point and/or LTCO temperature values.
