An air intake unit is ducted to a central heating and cooling installation. The intake fan unit has an outside temperature thermostat associated therewith and which is wired to a control circuit that also monitors temperature in proximity to a thermostat-equipped exhaust fan unit located in an attic or upper crawl space.
