The complete kit measures about 36 in along each horizontal axis and stands 20 in tall, with an approximate shipping weight of 75 lb. This low ambient control is intended for commercial rooftop and larger HVAC installations where precise outdoor-fan-speed control helps sustain system performance in cold weather.
