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.
Power exhaust is not available as a field installed
option.
•
POWER EXHAUST
- Our single economizer options are
available with power exhaust. Whenever the outdoor air
intake dampers are opened for free cooling, the exhaust
fan will be energized to prevent the conditioned space
from being over-pressurized during economizer operation.
The exhaust fan, motor and controls are installed and
wired at the factory. The rain hood and the back-draft
damper need to be assembled and installed in the field.
The power exhaust option can only be used on bot-
tom duct configurations.
•
MOTORIZED OUTDOOR AIR INTAKE DAMPER
-
Includes a slide-in / plug-in damper assembly with a 2-
position, spring return motor actuator which opens to a
pre-set position whenever the supply air blower is oper-
ating 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, REHEAT, AND
CONDENSER COILS
- Special coating process that uti-
lizes Technicoat 10-1" processes. Coating is applied by total
immersion of the complete coil for maximum protection.
•
ELECTRIC HEATERS
wired for single point power sup-
ply. 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 2”
throw-away filters installed. 2” pleated and 4” pleated fil-
ters are offered as a factory installed option.
•
CONVENIENCE OUTLET
- This 110 volt outlet can be
“powered” by the unit with a stepdown transformer or
you may order the unit with a “non-powered” conve-
nience 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.
•
DOUBLE WALL CONSTRUCTION -
Optional double
wall construction is available to provide smooth inner
surfaces for easy and effective cleaning to reduce risk of
dirt and bacterial accumulation. Fiberglass insulation is
sandwiched between heavy gauge steel sheets to form a
durable, rigid casing to withstand higher working pres-
sures and impact forces. The heavy-duty construction
provides excellent acoustic and thermal insulation and
eliminates erosion of insulation material and contamina-
tion of the air stream.

BAS - Building Automation System Controls
Simplic-
ity
® INTELLI-Comfort™ CONTROL -
The York®
Sim-
plicity
® 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 Outside Air Humidity sensor, a Return Air Humidity
sensor, an Inside IAQ sensor, and an Outside Air IAQ
sensor. Construction 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
sen-
sors. It uses an inside CO
2
sensor to perform Demand
Ventilation. It can also use an Outside CO
2
sensor to
perform Differential Demand Ventilation. It uses a Pat-
ented Comfort Ventilation algorithm to provide comfort-
able ventilation air temperature. The patented
economizer-loading algorithm will protect the equipment
when harsh operating conditions exist. Humidity in the
occupied space or return duct can be monitored and con-
trolled via humidity sensors and the on-board connection
for hot gas re-heat system. It uses the INTELLI-Start™
algorithm to maximize energy savings by recovering the
building from the Unoccupied Setpoints to the Occupied
Setpoints just in time for the Occupied Time Period to
begin. The
Simplicity
® INTELLI-Comfort™ balances
space temperature, ventilation air temperature, CO
2
and
humidity for ultimate comfort.
•
Simplicity
® INTELLI-Comfort™ with ModLINC CON-
TROL -
The York®
Simplicity
® INTELLI-Comfort™ with
ModLINC control is factory installed. It includes all the
features of the INTELLI-Comfort™ control with an addi-
tional control to translate communications from MOD-
BUS to the BACnet MSTP protocol.
