HVAC Attic Fan Operation
The routine of operation to secure the best and most efficient results with an attic fan is important. Atypical operating routine might require that, in the late afternoon when the outdoor temperature begins to fall, the windows on the first floor and the grilles in the ceiling or the attic floor be opened and the second-floor windows kept closed. This will place the principal cooling effect in the living rooms. Shortly before bedtime, the first-floor windows may be closed and those on the second floor opened to transfer the cooling effect to the bedrooms. Asuitable time clock may be used to shut the motor off before arising time.
