1. A furnace controller for controlling a modulating furnace, comprising:

  • an input device configured to;

    receive a first input comprising a heat request signal from a thermostat based on a temperature setpoint;

    receive a second input for an efficiency/comfort preference setting,wherein the efficiency/comfort preference setting is distinct from the temperature setpoint, andwherein the efficiency/comfort preference setting biases a control algorithm for controlling one or more plenum parameters of the modulating furnace, excluding the temperature setpoint; and

    a controller operatively coupled to the input device, the controller is configured to control the modulating furnace in accordance with the control algorithm,wherein the control algorithm causes an air temperature in a plenum of the modulating furnace to be dependent on the received efficiency/comfort preference setting for a given burner firing rate of the modulating furnace, andwherein the air temperature in the plenum is distinct from the temperature setpoint.
