Claim 7:
8. A method comprising, by a controller of a heating, ventilation and air conditioning (HVAC) system:
receiving an indoor air temperature (IAT) of an enclosed space to which conditioned air is provided by the HVAC system;
determining, based on a difference between the received IAT and the indoor temperature setpoint, that the IAT is not within a threshold range of an indoor temperature setpoint;
after determining that the IAT is not within the threshold range of the indoor temperature setpoint, determining an adaptive discharge air temperature setpoint based on a default discharge air temperature setpoint and the difference between the received IAT and the indoor temperature setpoint;
determining a compressor speed at which to operate a variable-speed compressor of the HVAC system based on the adaptive discharge air temperature setpoint; and
causing the variable-speed compressor to operate at the determined compressor speed.
