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.

• Unit Controllers - York's Sunline™ series offer factory
mounted Simplicity® SE UCB, with optional
Communication board, a 4-stage board if 4 stages are
required, an Economizer board, and an FDD (Fault
Detection and Diagnostic) board. A MAP Device can be
used to remotely access.

• 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:

• Dry Bulb 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.

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.

use with a standard thermostat (easy to connect screw
terminals), A zone sensor, or can be setup to
communicate with multiple BAS communication protocols
to integrate with building automation systems.

• Reduce field installed complexity - Each unit will comes
equipped with factory installed supply air, return air, and
outdoor air temperature sensors providing key
temperature readings thus reduce field installed
complexity.

• On-board USB Port - The new control comes with a long
list of features including data logging, current and
previous system faults and software update capabilities
using the on board USB port and common flash drive.
Energy use monitoring capabilities allow custom tailoring
to allow a system to work more efficiently at all times and
occupancy levels. Self test and start-up reports also
available from the board VIA the USB port.

• Embedded LCD Display - The board has a easy to read,
built-in LCD display and easy to use navigation joystick
and buttons allowing the user to quickly navigate the
menus displaying unit status, options, current function,
supply, return and outdoor temperatures, fault codes and
other information.

• Safety Monitoring - The control monitors the outdoor,
supply, and return air temperatures and the high and low
pressure switch status on the independent refrigerant
circuits. On units with heating the gas valve and high
temperature limit switches are monitored on gas and
electric heating units. The control also monitors the
voltage supplied to the unit and will protect the unit if low
voltage due to a brown out, or other electrical issue
occurs.

• Low Ambient - An integrated low-ambient control allows
units to operate in the cooling mode down to 0°F outdoor
ambient without additional components or intervention.
Optionally, the control board can be programmed to
lockout the compressors when the outdoor air
temperature is low or when free cooling is available.

• Anti-Short Cycle Protection - To aid compressor life, an
anti- short cycle delay is incorporated into the standard
control. Compressor reliability is further ensured by
programmable minimum run times. For testing, the anti­short cycle delay can be temporarily overridden with the
push of a button.

• 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/or heating capacity.

• Nuisance Trip Protection and Three Strikes - To
prevent nuisance calls, the control board uses a three
times, you're out philosophy. The high, low-pressure
switch, anti-freeze protection, low voltage or heating high
limit must trip three times within two hours before the unit

control board will lock out the associated compressor.An
alarm message will be displayed on the LCD screen.

• 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.

• 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
tubular heat exchangers carry a 10 year warranty.
Stainless steel heat exchangers a 15 year warranty.

Factory Installed Options

YORK® offers several equipment options factory installed, for
the ZJ/ZR/ZF Series.

• Dry Bulb 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

6 Johnson Controls Unitary Products

251934-YTG-BB-1014

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
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 for
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 multi-speed 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 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 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.

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).

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.
