Features and Benefits
Standard Features
• High Efficiency - High efficiency units reach as high as
12.4 EER. Gas/electric units have electronic spark ignition
and power vented combustion with steady state efficiencies
of 80%. These efficiencies exceed all legislated minimum
levels and provide low operating costs.
• Balanced Heating -
• Gas Heat - All gas heat units are built with two heating
sections for two equal stages of capacity control. Each
section includes a durable heat exchanger with
aluminized steel or optional stainless steel tubes, a
redundant gas valve, spark ignition, power venting, an
ignition module for 100% shut-off and all of the safety
controls required to meet the latest ANSI standards.
The gas supply piping can be routed into the heating
compartment through a hole in the base pan of the unit
or through a knockout in the piping panel on the front of
the unit.
• Electric Heat - All electric heat models (factory installed
only) are wired for a single power source and include a
bank of nickel chromium elements mounted at the
discharge of the supply air blower to provide a high velocity
and uniform distribution of air across the heating elements.
Every element is fully protected against excessive current
and temperature by fuses and two thermal limit switches.
The power supply wiring can be routed into the control
box through a threaded pipe connection in the base pan
of the unit or through a knockout in the wiring panel on
the front of the unit.
• BAS Controls - York's Sunline™ series units offer factory
mounted BAS controls such as Simplicity® SE with BAS
Option, CPC, JOHNSON, HONEYWELL, NOVAR, YORK
COMMERCIAL COMFORT SYSTEM (YCCS).
• Convertible Airflow Design - All models (including those
with an economizer) are suitable for either bottom or
horizontal duct connections. Models with factory
installed power exhaust are suitable for bottom duct
connections only. For bottom duct, you remove the sheet
metal panels from the supply and return air openings
through the base of the unit. For horizontal duct, you
replace the supply and return air panels on the rear of the
unit with a side duct flange accessory.
• Factory Mounted Outdoor Air Dampers - All models are
available with these "factory mounted" outdoor air damper
options:
• Single enthalpy economizer with or without power
exhaust
• BAS-ready economizer with or without power exhaust
• Motorized outdoor air damper
• Barometric Relief Damper
A fixed outdoor air intake assembly will be shipped in the
return air compartment of all units ordered without an
economizer or motorized outdoor air damper option. The
assembly includes a rain hood with a baffle that can be set
for 10, 15 or 25% outdoor air. With bottom duct connections,
the fixed outdoor air intake assembly should be mounted
over the opening in the return air panel. With horizontal
ductwork, it should be mounted on the return air duct.
• System Protection - Suction line freezestats are supplied
on all units to protect against loss of charge and coil frosting
when the economizer operates at low outdoor air
temperatures while the compressors are running. Every unit
has solid-core liquid line filter-driers and high and lowpressure switches. Internal compressor protection is
standard on all compressors. Phase Monitors are optional
on all units. This accessory monitors the incoming power to
the unit and protects the unit from phase loss and reversed
phase rotation.
• Advanced Controls - ZJ/ZR/ZF Models have Simplicity®
SE control boards that standardized a number of features
previously available only as options or by utilizing
additional controls.
• Low Ambient
allows all units to operate in the cooling mode down to
0F outdoor ambient without additional assistance.
Optionally, the control board can be programmed to
lockout the compressors when the outdoor air
temperature is low or when free cooling is available.
The Simplicity™ SE control board used in this
product will effectively operate the cooling system
down to 0°F when this product is applied in a comfort
cooling application for people. An economizer is
typically included in this type of application. When
applying this product for process cooling applications
(computer rooms, switchgear, etc.), please
reference applications bulletin AE-011-07 or call the
applications department for Unitary Products @ 1877-UPG-SERV for guidance. Additional
accessories may be needed for stable operation at
temperatures below 30°F.
• Anti-Short Cycle Protection - To aid compressor life,
an anti-short cycle delay is incorporated into the
standard controls. Compressor reliability is further
ensured by programmable minimum run times. For
testing, the anti-short cycle delay can be temporarily
overridden with the push of a button.
• Lead-Lag - An integrated Lead-Lag option allows equal
run time hours on all compressors, thereby extending
the life of all compressors. This option is selectable on
the unit control board.
• Fan Delays - Fan on and fan off delays are fully
programmable. Furthermore, the heating and cooling
fan delay times are independent of one another. All units
are programmed with default values based upon their
configuration of cooling and heat.
• Safety Monitoring - The control board monitors the
high and low-pressure switches, the freezestats, the gas
valve, if applicable, and the temperature limit switch on
gas and electric heat units. The unit control board will
- An integrated low-ambient control
Johnson Controls Unitary Products 5
251934-YTG-AA-0914
alarm on ignition failures, compressor lockouts and
repeated limit switch trips.
• Nuisance Trip Protection and Strikes - To prevent
nuisance trouble calls, the control board uses a “three
times, you’re out” philosophy. The high and lowpressure switches and the freezestats must trip three
times within two hours before the unit control board will
lock out the associated compressor.
• On Board Diagnostics - Each alarm will energize a
trouble light on the thermostat, if so equipp ed, an d flash
an alarm code on the control board LED. Each high and
low-pressure switch alarm as well as each freezestat
alarm has its own flash code. The control board saves
the five most recent alarms in memory, and these alarms
can be reviewed at any time. Alarms and programmed
values are retained through the loss of power.
• Reliable - From the beginning - All units undergo
computer automated testing before they leave the factory.
Units are tested for refrigerant charge and pressure, unit
amperage, and 100% functionality. For the long term - All
units are painted with a long lasting, powder paint that
stands up over the life of the unit. The paint used has
been proven by a 1000 hour salt spray test.
• Full Perimeter Base Rails - The permanently attached
base rails provide a solid foundation for the entire unit and
protect the unit during shipment. The rails offer rigging
holes so that an overhead crane can be used to place the
units on a roof.
• Easy Installation - Gas and electric utility knockouts are
supplied in the unit underside as well as the side of the
unit. Utility connections can be made quickly and with a
minimum amount of field labor. All units are shipped with
2" throw-away filters installed.
• Wide Range of Indoor Airflows - All supply air blowers
are equipped with a belt drive that can be adjusted to
meet the exact requirements of the job. A high static drive
option is available for applications with a higher CFM and/
or static pressure requirement.
• Warranty - All models include a 1-year limited warranty
on the complete unit. Compressors and electric heater
elements each carry a 5-year warranty. Aluminized steel
and stainless steel tubular heat exchangers carry a 10year warranty.
Factory Installed Options
YORK® offers several equipment options factory installed, for
the ZJ/ZR/ZF Series.
• Single Input Electronic Enthalpy Economizers - All
units offer a variety of optional factory installed down flow
economizers that are shipped, installed and wired with low
leak dampers designed to meet ASHRAE 90.1-2010,
AMCA 511 Class 1A damper, and the International
Energy Conservation Code (IECC) certification
requirements by achieving leakage rates of 3 cfm/sq. ft. at
1" of static pressure. Each economizer goes through a
rigorous 60,000 cycle test. Dry bulb, single enthalpy, and
dual enthalpy (with field installed kit) can be selected. All
economizer options are fully integrated into the
Simplicity® SE controls. The economizer has spring
return, fully modulating damper actuators and is capable
of introducing up to 100% outdoor air. As the outdoor air
intake dampers open, the return air dampers close. The
changeover from mechanical refrigeration to economizer
operation is regulated by the outdoor air dry bulb
temperature or the outdoor air enthalpy input. The dual
enthalpy kit provides a second input used to monitor the
return air (field installed). The installer needs only to
assemble the outdoor air hood, attach the enthalpy control
the hood and mount the hood to the unit (Hood and
control are provided).
• Power Exhaust - Our 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 must be assembled
and installed in the field.
The power exhaust option can only be used on bottom
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 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.
• Barometric Relief Damper - This damper option can be
used to relieve internal building air pressure on units with
an economizer without power exhaust. This accessory
includes a rain hood, a bird screen and a fully assembled
damper. With bottom duct connections, the damper
should be mounted over the opening in the return air
panel. With horizontal ductwork, the accessory should be
mounted on the return air duct.
• Technicoat Condenser Coils - The condenser coils are
coated with a phenolic coating for protection against
corrosion due to harsh environments.
• Technicoat Evaporator Coil - The evaporator coils are
coated with a phenolic coating for protection against
corrosion due to harsh environments.
• E-Coat Condenser Coils - The condenser coils are
coated with an epoxy polymer coating to protect against
corrosion.
• E-Coat Evaporator Coils - The evaporator coils are
coated with an epoxy polymer coating to protect against
corrosion.
• Electric Heaters - wired for single point power supply.
These nickel chromium heater elements are provided with
limit and automatic reset capability to prevent operation at
excessive temperatures.
• Variable Air Volume (VAV) - A factory-installed variable
frequency drive (VFD), mounted in the Blower Access
compartment, is used to control the speed of the indoor
blower motor in order to maintain a constant static
pressure in the supply duct. A pressure transducer and
6 Johnson Controls Unitary Products
251934-YTG-AA-0914
VAV control board are mounted inside the control box.
The drive comes completely wired and pre-programmed
from the factory.
An optional, factory-installed manual bypass switch
available with factory-installed VFD can be found in the
Blower Motor Access compartment. The switch can be
used to either route power to the VFD for modulating
control of the blower motor, to bypass the drive and
operate the motor at full speed, or to power the drive (and
not the motor) for diagnostic purposes.
Due to space limitations, VAV is not available with any of
the factory-installed BAS options described below, but is
available with ‘BAS-ready’ models. Terminal blocks are
provided in the control box for field wiring of the customerinstalled BAS.
A ‘VFD-ready’ option provides the provisions for a
customer-installed drive. The unit comes with a mounting
bracket installed in the Blower Access compartment which
may accommodate other vendor’s drives depending on
their size. In order to utilize the unit’s mounting bracket,
the maximum recommended drive dimensions are as
follows:
For 5-hp motor applications........................ 13” H x 6” W x 7” D
For 7.5 thru 15-hp motor applications ........ 13” H x 8” W x 8” D
If the drive will not fit in the allotted space, then it will have
to be mounted elsewhere; either within the building on a
perpendicular wall which is not subjected to excessive
temperature, vibration, humidity, dust, corrosive gas,
explosive gas, etc., or within an appropriate enclosure
rated for outside installation to safeguard against
moisture, dust and excessive heat.
A terminal block located in the control box is provided fo r
field connection of the VFD controls.
• IntelliSpeed™ Supply Fan Control Option (ASHRAE
90.1 compliant, section 6.4.3.10) - Units configured with
the IntelliSpeed™ Supply Fan Option will contain a VFD
for variable volume supply fan operation. This option
allows the supply fan RPM to vary based on the number
of compressors or heating stages energized. The
economizer's minimum position will also be configurable
to vary based on the supply fan VFD frequency output.
• Hot Gas Bypass - To allow for low cooling load operation,
a direct-acting pressure-modulating bypass control valve
installed on the system #1 discharge line is used to divert
high temperature, high pressure refrigerant around the
TXV in order to maintain a desired minimum evaporator
pressure. HGBP is standard on all units with VAV and
optional with CV units.
• Filter Options - Standard units are shipped with 2" throwaway filters installed. 2" pleated and 4" 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 you
may order the unit 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 th e 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 pressures and impact
forces. The heavy-duty construction provides excellent
acoustic and thermal insulation and eliminates erosion of
insulation material and contamination of the air stream.
• York Commercial Comfort System (YCCS) - Provides
rooftop system integration for YCCS single zone, changeover bypass and VAV systems.
• Smoke Detectors - (supply air & return air) The smoke
detectors stop operation of the unit by interrupting power
to the control board if smoke is detected within the air
compartment.
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.
• Coil Guard - Customers can purchase a coil guard kit to
protect the condenser coil from damage. This is not a hail
guard kit.
• Stainless Steel Heat Exchanger - For applications in
corrosive environments, this option provides a full
stainless steel heat exchanger assembly.

Field Installed Accessories
YORK® offers several equipment accessories for field
installation, for the ZJ/ZR/ZF Series.
• Single Input Electronic Enthalpy Economizers - All
units offer a variety of optional factory installed down flow
economizers that are shipped, installed and wired with low
leak dampers designed to meet ASHRAE 90.1-2010,
AMCA 511 Class 1A damper, and the International
Energy Conservation Code (IECC) certification
requirements by achieving leakage rates of 3 cfm/sq. ft. at
1" of static pressure. Each economizer goes through a
rigorous 60,000 cycle test. Dry bulb, single enthalpy, and
dual enthalpy (with field installed kit) can be selected. All
economizer options are fully integrated into the Simplicity
SE controls. The economizer has spring return, fully
modulating damper actuators and is capable of
introducing up to 100% outdoor air. As the outdoor air
intake dampers open, the return air dampers close. The
changeover from mechanical refrigeration to economizer
operation is regulated by the outdoor air dry bulb
temperature or the outdoor air enthalpy input. The dual
enthalpy kit provides a second input used to monitor the
return air (field installed). The installer needs only to
assemble the outdoor air hood, attach the enthalpy control
the hood and mount the hood to the unit (Hood and
control are provided).
• Motorized Outdoor Air Intake Damper - Includes a
slide-in / plug-in damper assembly with a 2-position,
spring return motor actuator which opens to some 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.
• Roof Curbs - Fourteen-inch high roof curbs provide a
water-tight seal between the unit and the finished roof.
These full perimeter curbs meet the requirements of the
National Roofing Contractors Association (NRCA) and are
shipped knocked-down for field assembly.
They're designed to fit inside the base rails of the unit and
include both a wood nailing strip and duct hanger supports.
• High Altitude Natural Gas - Burner orifices and pilot
orifices are provided for proper furnace operation at
altitudes up to 6,000 feet.
• Propane - Burner orifices, pilot orifices and gas valve parts
are provided to convert a natural gas furnace to propane.
• High Altitude Propane - Burner orifices and pilot orifices
are provided for proper furnace operation at altitudes up
to 6,000 feet. This accessory supplements the basi c
propane conversion kit.
• Side Duct Flanges - One-inch flanges replace the supply
and return air panels on the rear of the unit to accommodate
horizontal duct connections. These flanges can also be used
individually for bottom supply / horizontal return or horizontal
supply/bottom return. They cannot be used on units with
power exhaust.
• Barometric Relief Damper - This damper accessory can
be used to relieve internal building air pressure on units
with an economizer without power exhaust. This
accessory includes a rain hood, a bird screen and a fully
assembled damper. With bottom duct connections, the
damper should be mounted over the opening in the return
air panel. With horizontal ductwork, the accessory should
be mounted on the return air duct.
• High Static Drive - May include a belt, blower pulley,
motor pulley or a motor change to enhance blower
performance.
• Enthalpy Accessory Control Kit - This kit contains the
required components to convert a single enthalpy
economizer to dual enthalpy.

• Burglar Bars - Mount in the supply and return openings
to prevent entry into the duct work.
• Flue Exhaust Extension Kit - In locations with wind or
weather conditions which may interfere with proper
exhausting of furnace combustion products, this kit can be
installed to prevent the flue exhaust from entering nearby
fresh air intakes.
• Wood Skid - Allows unit to be handled with 90" forks.
Sensor - Senses CO2 levels and automatically

Normal Occupied Operation Mode
If the return humidity is greater than or equal to the Hot Gas
Reheat Humidity Setpoint, and no demand for cooling, C1
output energizes and the AUX-HGR output energizes.
If there is a demand for one stage of cooling and the return
humidity is greater than or equal to the Hot Gas Reheat
Humidity Setpoint, C1 output energizes but the AUX-HGR
output de-energizes.
Any additional cooling demands energize compressor outputs,
but do not change the status of the AUX-HGR output.
NOTE: If HGR Enabled for Unoccupied Operation is enabled,
during unoccupied mode the control works the same as
described above, except it uses the HGR Unoccupied
Humidity Setpoint instead.
Alternate Mode
If the return humidity is greater than or equal to the Hot Gas
Reheat Humidity Setpoint, and no demand for cooling, C1 and
AUX-HGR outputs energize, and C2 energizes.
If there is a demand for one stage of cooling and the return
humidity is greater than or equal to the Hot Gas Reheat
Humidity Setpoint, C1 and AUX-HGR outputs energize, and C2

1. Add these values to the available static resistance in the respective Blower Performance Tables.
2. Deduct these values from the available external static pressure shown in the respective Blower Performance Tables.
3. The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the
return air duct is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.

For units with VFD and gas heat, the speed of the indoor
blower motor continues to be controlled by duct static
pressure via the VAV control board.
If there are VAV boxes present in the duct system,
the boxes must be driven to the full-open position
using a customer-supplied power source to assure
adequate airflow across electric heating elements
or gas heat exchanger tubes.
