Systems and methods for dehumidification using climate control systems

A climate control system comprising:

• an indoor unit that is configured to condition an airflow for a conditioned space;
• an outdoor unit including a compressor configured to circulate a refrigerant between the indoor unit and the outdoor unit, the compressor operable at a first speed in a first stage and operable at a second speed in a second stage, the second speed being is greater than the first speed;
• a thermostat that is configured to determine a relative humidity of the conditioned space and to output a dehumidification signal to the indoor unit in response to a determination that the relative humidity is above a threshold;
• and
• a relay connected between the indoor unit and the outdoor unit that is configured to conduct electrical current from the indoor unit to the outdoor unit to operate the compressor in the second stage in response to the dehumidification signal to reduce the relative humidity in the conditioned space;
• wherein the relay is coupled to an electrical power source terminal, a compressor speed terminal of the indoor unit associated with the second stage of the compressor, and a compressor speed terminal of the outdoor unit associated with the second stage of the compressor;
• wherein the dehumidification signal is configured to change an electrical energization of the relay to cause the relay to conduct the electrical current from the indoor unit to the outdoor unit to operate the compressor in the second stage;
• wherein the dehumidification signal is configured to change an electrical energization of the relay to actuate the relay from a first position to a second position;
• wherein, in the first position, the compressor speed terminal of the indoor unit is electrically coupled the compressor speed terminal of the outdoor unit, and the electrical power source terminal is electrically decoupled from the compressor speed terminal of the outdoor unit;
• and
• wherein, in the second position, the compressor speed terminal of the indoor unit is electrically decoupled from the compressor speed terminal of the outdoor unit, and the electrical power source terminal is electrically coupled to the compressor speed terminal of the outdoor unit.

An air conditioning system, comprising:

• a thermostat configured to monitor a temperature and a relative humidity of a conditioned space, the thermostat comprising:
• a first terminal associated with a first cooling demand based on the temperature;
• a second terminal associated with a second cooling demand based on the temperature, the second cooling demand being greater than the first cooling demand;
• and
• a third terminal associated with the relative humidity;
• a first conditioning unit comprising a first heat exchanger and a blower configured to generate an airflow past the first heat exchanger in at least a first blower speed, a second blower speed, and a third blower speed, the first blower speed being less than the second blower speed, and the second blower speed being less than the third blower speed;
• a second conditioning unit comprising a second heat exchanger and a compressor configured to circulate a refrigerant between the first heat exchanger and the second heat exchanger, the compressor having a first speed and a second speed, the first speed being less than the second speed;
• and
• wiring coupling the thermostat to the first conditioning unit and the second conditioning unit such that:
• when only the first terminal of the first, second, and third terminals is active on the thermostat, the blower operates at the second blower speed and the compressor operates at the first speed;
• when only the first and second terminals of the first, second, and third terminals on the thermostat are active, the blower operates at the third blower speed and the compressor operates at the second speed;
• and
• when only the first and third terminals of the first, second, and third terminals are active, the blower operates at the first blower speed and the compressor operates at the second speed.
