Abstract:
1. A single integrated control for an HVAC system comprising: an indoor temperature sensor; an indoor relative humidity sensor; an outdoor temperature sensor; an indoor relative humidity sensor; a central control unit that operates in a heating mode and a cooling mode, wherein said central control unit is operable to receive inputs from said indoor temperature sensor, said indoor relative humidity sensor and said outdoor temperature sensor to manipulate an actual indoor temperature level, an actual indoor relative humidity level, and an actual indoor fresh air level during both a heating season and a cooling season; and a user interface operable for a user to input an at least one user desired indoor temperature, an at least one user desired indoor relative humidity, and a user desired indoor fresh air level, wherein said central control unit generated signals based upon said inputs to manipulate said actual indoor temperature level, said actual indoor relative humidity level, and said actual indoor, fresh air level to achieve said at least one user desired indoor temperature, said at least one user desired indoor relative humidity, and said use desired indoor fresh air level; and wherein when said central control operates in said cooling mode, said at least on user desired indoor temperature includes a user desired indoor cooling temperature, and said at least on user desired indoor relative humidity includes a user desired indoor relative cooling humidity, said actual indoor relative humidity level being increased when said actual indoor relative humidity level is lower than said user desired indoor relative cooling humidity.
