FACTORY-INSTALLED OPTIONS
• SINGLE INPUT ELECTRONIC ENTHALPY ECONO-
MIZERS - Includes a slide-in / plug-in damper assembly
with fully modulating spring-return motor actuator capa-
ble of introducing up to 100% outdoor air with nominal
1% leakage type dampers.
The enthalpy system contains one sensor that monitors
the outdoor air and determines when the air is cool
enough and dry enough to provide free cooling.
The rainhood is painted to match the basic unit and must
be field-assembled before installing.
• MOTORIZED OUTDOOR AIR INTAKE DAMPER -
Includes a slide-in / plug-in damper assembly with a 2-posi-
tion, spring return motor actuator which opens to a pre-set
position whenever the supply air blower is operating and
will drive fully closed when the blower unit shuts down.
The rain hood is painted to match the basic unit and
must be field assembled before installing.
• PHENOLIC COATED EVAPORATOR AND CON-
DENSER COILS - Special coating process that utilizes
Technicoat 10-1™ processes. Coating is applied by total
immersion of the complete coil for maximum protection.
• ELECTRIC HEATERS - Wired for single point power
supply. These nickel chromium heater elements are pro-
vided with limit and automatic reset capability to prevent
operation at excessive temperatures.
• FILTER OPTIONS - Standard units are shipped with 1”
throw-away filters installed. 2” pleated filters are offered
as a factory installed option.
• CONVENIENCE OUTLET - This 110 volt outlet can be
“powered” by the unit with a stepdown transformer or the
unit may be ordered with a “non-powered” convenience
outlet that can be wired in the field.
• DISCONNECT SWITCH - For gas heat units and cooling
units with electric heat, a HACR breaker sized to the unit
is provided. For cooling only units, a switch sized to the
largest electric heat available for the particular unit is
provided. Factory installed option only.

INTELLI-Comfort™ CONTROL - The York®
Simplicity
®
INTELLI-Comfort™ control is factory installed.
It includes a supply air sensor, a return air sensor, and an
outside air sensor. There are provisions for a field installed
dirty filter indicator switch, an air-proving switch, an Out-
side Air Humidity sensor, a Return Air Humidity sensor, an
Inside IAQ sensor, and an Outside Air IAQ sensor. Con-
struction mode operation, 365-day real time clock with 7
day programming plus holiday scheduling is built-in. Two
different modes of demand ventilation are achieved
through the INTELLI-Comfort™using CO
2
sensors. It
uses an inside CO
2
sensor to perform Demand Ventila-
tion. It can also use an Outside CO
2
sensor to perform
Differential Demand Ventilation. It uses a Patented Com-
fort Ventilation algorithm to provide comfortable ventilation
air temperature. The patented economizer-loading algo-
rithm will protect the equipment when harsh operating
conditions exist. Humidity in the occupied space or return
