Abstract: A method for controlling an actuator of a terminal unit in a climate control system includes, in a calibration mode: applying a range of drive signals to the actuator; determining a range of terminal unit capacities over the range of drive signals; and generating a model relating the range of terminal unit capacities to the range of drive signals.

Abstract: A method for controlling a terminal unit in a climate control system includes detecting a stuck position of a first actuator in the terminal unit; receiving a command signal identifying a commanded capacity; and controlling a second actuator in the terminal unit in response to the stuck position of the first actuator and the commanded capacity.

Abstract: A method for selecting a fluid pressure of a fluid supplied to a plurality of terminal units in a climate control system includes adjusting the fluid pressure over a range over fluid pressures; determining a terminal unit efficiency for each terminal unit over the range of fluid pressures; determining a range of combined terminal unit efficiencies over the range of fluid pressures; identifying a range of bottom terminal unit efficiencies over the range of fluid pressures; and selecting a selected fluid pressure at which (i) a combined terminal unit efficiency is within a first threshold of a combined terminal unit efficiency limit and/or (ii) a bottom terminal unit efficiency is within a second threshold of a bottom terminal unit efficiency limit.
