Electric Heaters - The electric heaters range from 9kW

to 54kW and are available in all the voltage options of the

base units. All heaters are dual staged. All heaters are

intended for single point power supply.

•

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.

•

Convenience Outlet - (Non-Powered / Powered) - This

option locates a 120V single-phase GFCI outlet with

cover, on the corner of the unit housing adjacent to the

compressors. The "Non-powered" option requires the

installer to provide the 120V single-phase power source

and wiring. The "Powered" option is powered by a step-

down transformer in the unit. Factory installed option only.

•

Smoke Detectors - The smoke detectors stop operation

of the unit by interrupting power to the control board if

smoke is detected within the air compartment. Available

for both the supply and/or return air.

Factory installed smoke detectors in the return air,

may be subjected to freezing temperatures during

"off" times due to out side air infiltration. These

smoke detectors have an operational limit of 32 °F

to 131°F. Smoke detectors installed in areas that

could be out side those limitations will have to be

moved to prevent having false alarms.

•

Phase Monitors - Designed to prevent unit damage.

The phase monitor will shut the unit down in an out-of

phase condition. (Standard on units with Scroll Com-

pressors.)

•

Coil Guard - Customers can purchase a coil guard kit to

protect the condenser coil from damage. Additionally,

this kit stops animals and foreign objects from entering

the space between the inner condenser coil and the

main cabinet. This is not a hail guard kit.

•

Dirty Filter Switch - This kit includes a differential pres-

sure switch that energizes the fault light on the unit ther-

mostat, indicating that there is an abnormally high

pressure drop across the filters. Factory installed option

or field installed accessory.

•

Technicoat Condenser Coils - The condenser coils are

coated with a phenolic coating for protection against cor-

rosion due to harsh environments.

•

Technicoat Evaporator Coil - The evaporator coils are

coated with a phenolic coating for protection against cor-

rosion due to harsh environments.

BAS - Building Automation System Controls Simplic-

ity™ INTELLI-Comfort™ Control - The York® Simplic-

ity™ 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

sensors. It uses an inside CO

Demand Ventilation. It can also use an Outside CO

sor to perform Differential Demand Ventilation. It uses a

Patented Comfort Ventilation algorithm to provide com-

fortable ventilation air temperature. The patented econo-

mizer-loading algorithm will protect the equipment when

harsh operating conditions exist. Humidity in the occu-

pied 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

humidity for ultimate comfort.

•

Simplicity™ INTELLI-Comfort™ with ModLINC

Control - The York® Simplicity™ INTELLI-Comfort™

with ModLINC control is factory installed. It includes all

the features of the INTELLI-Comfort™ control with an

additional control to translate communications from

MODBUS to the BACnet MSTP protocol.

•

YK-UNT-1126 building automation system controller is

factory installed. Includes supply air sensor, return air

sensor, dirty filter indicator switch, and air proving switch.

•

Model 810-3060 ARTC Advanced Rooftop building auto-

mation system controller is factory installed. Includes

supply air sensor, return air sensor, dirty filter indicator

switch and air proving switch.

•
