Abstract
A method of calculating a control parameter for a component in an HVAC system includes receiving a plurality of input signals, and calculating a value of the control parameter using a control parameter equation having a plurality of predetermined coefficients and a plurality of variables, each variable corresponding to one of the input signals. This equation is stored in and subsequently fetched from memory associated with a component of the HVAC system, such as a blower motor controller or a system controller. In some embodiments, the equation is stored in a device for interfacing a system controller with a blower motor assembly.
