Claim 23:
24. A climate control system comprising:
an outdoor unit including:
a housing,
an adjustable compressor located within the housing and configured to circulate a refrigerant fluid through the climate control system,
a humidity sensor located within the housing and configured to detect a measurement representative of a humidity condition of an outdoor ambient environment,
a pressure sensor coupled to the housing and configured to detect a pressure representative of the refrigerant fluid proximate an inlet to the adjustable compressor, and
control circuitry located within the housing and coupled to the adjustable compressor, the humidity sensor, and the pressure sensor; and

a non-communicating thermostat located outside the housing and associated with a conditioned space,
wherein the control circuitry is further coupled to the non-communicating thermostat via a 24 volt (24V) communication protocol and configured to:
receive a request for a cooling mode from the non-communicating thermostat via the 24V communication protocol;
operate the outdoor unit in the cooling mode in response to the request;
establish a target parameter for controlling an operation of the adjustable compressor, the target parameter associated with the temperature of the refrigerant fluid circulated within the climate control system;
receive a signal indicative of the measurement associated with the humidity condition of the outdoor ambient environment from the humidity sensor;
convert the measurement representative of the humidity condition to an offset value, the offset value indicative of a latent cooling load associated with an indoor space conditioned by the climate control system;
adjust the target parameter based on the offset value, the adjustment establishing an adjusted target parameter,
monitor the temperature of the refrigerant fluid proximate the inlet to the adjustable compressor using the measurements received from the pressure sensor,
compare the monitored temperature to the adjusted target parameter, and
adjust an operation of the adjustable compressor based, at least in part, on the comparison of the monitored temperature to the adjusted target parameter.
