Patent ID: 8091375

Claim:
A method of controlling an HVAC system, comprising: allowing a user of a thermostat controller of the HVAC system to select between enabling and disabling a humidity control for use in a cooling mode of the HVAC system that selectively operates a compressor in response to a call for cooling, wherein the disabling the humidity control comprises allowing the user to override an otherwise automatic enablement of the humidity control; Enabling the humidity control in response to the user selecting to enable the humidity control via the thermostat controller; operating a fan of the HVAC system according to an overridable user selectable fan control preference that, when not overridden by the humidity control, causes operation of the fan independent of a call for cooling of the HVAC system; and in response to enabling the humidity control, operating the humidity control to selectively override the overridable user selectable fan control preference that, but for being selectively overridden by the humidity control, causes operation of the fan independent of the call for cooling; wherein operating the humidity control comprises after selectively overriding the overridable user selectable fan control preference, discontinuing the overriding of the overridable user selectable fan control preference; and wherein the discontinuing the overriding of the overridable user selectable fan control preference is conditioned on a comparison between a humidity setpoint selected via the thermostat controller and a sensed humidity.
