Abstract

An integrated attic ventilation, air conditioning and heating system electronic controller, with a system and method for use of the same, is disclosed. In one embodiment, the integrated electronic controller includes a housing configured to be secured within an attic space in a building structure having a living area. A temperature input and humidity input receive ambient temperature and humidity readings, respectively. The ambient measurements are compared to pre-determined temperature and humidity thresholds. If a threshold is exceeded, signals are send to actuate, in a coordinated fashion, a powered air intake and powered attic exhaust assembly. The powered air intake and powered attic exhaust assembly are operated intermittently, in coordination with the HVAC system, initially at a first set of extreme thresholds and operated constantly at a second set of more extreme thresholds.
