Temperature, humidity levels and air quality can all affect physical health, mental attitude, general comfort and energy savings. With today’s technological advances, you can achieve a “Perfect Climate” indoors. The Honeywell Perfect Window™ Fresh Air Ventilation System removes stale, unhealthy air and replaces it with a stream of fresh air. Its powerful centrifugal blowers bring fresh air into your home and at the same time, exhaust stale air in an equal amount. Both incoming and outgoing airstreams pass through either a heat transfer core or an energy transfer core where the heat only or the heat and the moisture from the exhaust air are efficiently transferred to the incoming fresh air. An air duct system supplies the fresh air brought in by the Perfect Window™ ventilator and distributes it throughout your home. Another duct draws the existing stale, air back to the Perfect Window™ ventilator and then exhausts it outdoors. It’s really very simple...and remarkably effective! The Perfect Window™ Fresh Air Ventilation System consists of: 1. Air Circulation FAN and Motor Inside the casing are two fans, one for exhaust and one for fresh air supply. The electric motor that operates the fan is 1/15 hp to 1/20 hp (depending on the ventilator model) and uses the same amount of power as a 100 watt light bulb. 2. Air Filters There are two permanent washable air filters in your ventilator. The filters lower the amount of dust and outside particulates entering the ventilator core and your fresh air supply. 3 69-1188—03 3. Condensate Tray and Drain (Some Models) Condensation normally forms on the energy transfer core during the cold weather (below 27°F or -3°C). Moisture can build up when the warm air from your home comes in contact with the cold air from outside. The tray collects the moisture and funnels it to the drain. The drain pans are made of thermoformed plastic for easy cleaning. 4. Defrost Mechanism (Some Models) Some models have an electronically-controlled damper frost control mechanism to prevent frost buildup on the core. Defrost timing will change based on incoming outdoor air temperature. Outdoor Temperature Defrost Timer 27°F (-3°C) 3 minute defrost/25 minute run -4°F (-20°C) 4.5 minute defrost/17 minute run -31°F (-35°C) 7 minute defrost/15 minute run Example: When the outside temperature drops below 27°F (-3°C) the defrost timer is activated. At the end of the 25-minute run cycle, when the core can experience some nominal fr...
