ABSTRACT:
HVAC systems are employed to control the indoor environmental characteristics of a building structure to make it comfortable for its inhabitants. An HVAC system includes one single integrated central control to regulate an indoor temperature level, an indoor relative humidity level and an indoor fresh air level of a building structure during both a heating season and a cooling season. Further, the single integrated central control is operable to selectively activate/deactivate an indoor blower to control a sensible ratio within a building structure. In addition, a protection feature for avoiding condensation on the interior surfaces of the building structure is included as an user selectable option.
