ABSTRACT:
A unit ventilator includes a means for selecting a minimum volume of fresh air to be delivered to a room in accordance with governmental ventilation codes. A control means is responsive to the selecting means and adjusts an outside air damper to achieve the minimum volume of fresh air selected. An outside air temperature sensor provides a signal corresponding to outside air temperature. The damper control means is responsive to said signal for reducing the volume of outside air admitted to the ventilator in corresponding relation to the outside air temperature so that the volume of fresh air delivered to the room is maintained substantially constant.
