Coating is applied by totalimmersion of the complete coil for maximum protection.• ELECTRIC HEATERS - Wired for single point powersupply. These nickel chromium heater elements are pro-vided with limit and automatic reset capability to preventoperation at excessive temperatures.• FILTER OPTIONS - Standard units are shipped with 1”throw-away filters installed. 2” pleated filters are offeredas a factory installed option.• CONVENIENCE OUTLET - This 110 volt outlet can be“powered” by the unit with a stepdown transformer or theunit may be ordered with a “non-powered” convenienceoutlet that can be wired in the field.• DISCONNECT SWITCH - For gas heat units and coolingunits with electric heat, a HACR breaker sized to the unitis provided. For cooling only units, a switch sized to thelargest electric heat available for the particular unit isprovided. Factory installed option only.• BAS - Building Automation System ControlsSimplicity® INTELLI-Comfort™ CONTROL - The York®Simplicity® INTELLI-Comfort™ control is factory installed.It includes a supply air sensor, a return air sensor, and anoutside air sensor. There are provisions for a field installeddirty filter indicator switch, an air-proving switch, an Out-side Air Humidity sensor, a Return Air Humidity sensor, anInside IAQ sensor, and an Outside Air IAQ sensor. Con-struction mode operation, 365-day real time clock with 7day programming plus holiday scheduling is built-in. Twodifferent modes of demand ventilation are achievedthrough the INTELLI-Comfort™ using CO2 sensors. Ituses an inside CO2 sensor to perform Demand Ventila-tion. It can also use an Outside CO2 sensor to performDifferential Demand Ventilation. It uses a Patented Com-fort Ventilation algorithm to provide comfortable ventilationFIGURE 1 - UNIT CUTAWAY
