A climate-control system includes a variable-capacity compressor, an outdoor ambient temperature sensor, a user-controlled device, and a control module. The outdoor ambient temperature sensor indicates a temperature of outdoor ambient air. The user-controlled device provides a demand signal indicating a demand for at least one of heating and cooling. The control module commands a compressor stage and a stage run time based on the temperature from the outdoor ambient temperature sensor and the demand signal. The control module also modifies a lockout threshold based on a cycle run time, where the cycle run time is an actual run time for the compressor to meet a setpoint temperature.
