1. A method of interactively and graphically interfacing with a user of an HVAC system controlled by a thermostat, the method comprising:

  • storing a plurality of programmed setpoints on a memory on the thermostat, each of the setpoints being associated with a setpoint temperature and a time at which the setpoint is programmed to become active;

    on a small format touch-screen display device in a location remote from the thermostat, graphically displaying a two dimensional plot including one or more setpoint icons each being associated with one of the plurality of programmed setpoints, such that the position of each setpoint icon indicates to the user the temperature by virtue of a position of the icon along a first axis and the time by virtue of a position of the icon along a second axis associated with the associated setpoint;

    receiving user input in a form of a single touch-dragging motion by the user of a displayed setpoint icon indicating an intention by the user to adjust (1) the temperature of the setpoint associated with the icon by virtue of the single touch-dragging motion being primarily in a direction parallel to the first axis, or (2) the time of the setpoint associated with the icon by virtue of the single touch-dragging motion being primarily in the direction of the second axis; and

    constraining user adjustments to time adjustments when the received user input indicates an intention to adjust the time, and constraining user adjustments to temperature adjustments when the received user input indicates an intention to adjust the temperature.
