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® Intelli-Comfort
II, Novar, Honeywell, Johnson, York Commercial
Comfort System (YCCS) and CPC.
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 damper 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 low-
pressure 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 - Simplicity™ ZJ/ZR/ZF control
boards have standardized a number of features
previously available only as options or by utilizing
additional controls.
Low Ambient - An integrated low-ambient control
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.
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
The Simplicity® 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 @ 1-
877-UPG-SERV for guidance. Additional
accessories may be needed for stable operation at
temperatures below 30°F.

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 low-
pressure 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 equipped, and 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 10-
year warranty.
Factory Installed Options
YORK® offers several equipment options factory installed, for
the ZJ/ZR/ZF Series.
Single Input Electronic Enthalpy Economizers -
Includes a slide-in / plug-in damper assembly with fully
modulating spring-return motor actuator capable 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.
BAS-Ready Economizer - Includes a slide-in / plug-in
damper assembly with fully modulating spring-return
motor actuator with zero to 95-degree rotation capable of
introducing up to 100% outdoor air with nominal 1%
leakage type dampers.
Actuator requires 2-10 VDC input from an external source,
such as a field-installed or factory-installed BAS
controller. BAS-ready actuators have an adjustable
auxiliary end-switch for optional power exhaust control.
For units with optional VAV or Simplicity® Intelli-Comfort
II™ control, a factory-installed, dry bulb sensor
determines if outdoor air temperature is low enough to
provide free-cooling operation. (Field-installed humidity
sensors for either outdoor air or outdoor & return air
streams are available for single enthalpy and differential
enthalpy configurations, respectively).
The rain hood is painted to match the basic unit and must
be field-assembled before installing.
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

251934-YTG-R-0612
Johnson Controls Unitary Products 7
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 customer-
installed 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.
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" throw-
away 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

Reheat Mode Sequence Of Operation
The reheat control board allows the user to select two different
modes of operation via a jumper connection on the board. (See
Reheat Control Board.) Each mode is described below. Refer to
Reheat Controls - Part 1 and Part 2 when reading this section.
“Normal” Mode
When the reheat control board (RCB) detects a need for
dehumidification (24VAC) at "HUM" via the field supplied
dehumidistat connected to RHTB-1 and RHTB-2 and there is
not a call for cooling, it energizes the hot gas relay (HGR),
which energizes the 3-way valve (SOL 3), the condenser coil
valve (SOL 2), and de-energizes the reheat coil bleed valve
(SOL 1). The Y1 signal is passed to the unit control board
(UCB), which engages circuit # 1, resulting in circuit #1 reheat
mode operation.
When the room thermostat calls for first stage cooling, with or
without a call for dehumidification, the RCB senses a signal
through "Y1", de-energizing the HGR, which de-energizes SOL
3 and SOL 2, and energizes SOL 1, engaging circuit # 1,
resulting in circuit #1 cooling mode operation.
When the room thermostat calls for second stage cooling, the
RCB senses a signal through "Y1" & "Y2" and engages circuit
#1 and circuit #2 in the cooling mode.
Indoor blower operation is initiated upon a call for first stage
cooling, second stage cooling or dehumidification.
Anytime there is a call for 2 stages of cooling, the unit will not
operate in the reheat mode, even if there is a call for
dehumidification at "HUM".
The unit will not operate in the reheat mode if there is any call
for heating.
On units with economizers, the unit will not operate in the
reheat mode if there is a call for cooling and the economizer is
operating as first stage of cooling.
All safety devices function as previously described.
"Alternate” Mode
When the RCB detects a need for dehumidification (24VAC) at
"HUM" via the field supplied dehumidistat connected to RHTB-1
and RHTB-2, and there is not a call for cooling, it energizes the
HGR, which energizes the SOL 3, SOL 2, and de-energizes
SOL 1. The unit then operates with circuit #1 in reheat mode
and circuit #2 in cooling mode.
When the room thermostat calls for first stage cooling while
there is still a call for dehumidification, no operational change is
made. The call for cooling is ignored and the unit continues to
operate with circuit #1 in reheat mode and circuit #2 in cooling
mode.
When the room thermostat calls for second stage cooling, the
RCB senses a signal through "Y1" & "Y2" and de-energizes the
HGR, which de-energizes SOL 3 and SOL 2, and energizes
SOL 1. Both circuits operate in the cooling mode.
Indoor blower operation is initiated upon a call for first stage
cooling, second stage cooling or dehumidification.
Anytime there is a call for 2 stages of cooling, the unit will not
operate in the reheat mode, even if there is still a call for
dehumidification at "HUM".
The unit will not operate in the reheat mode if there is any call
for heating.
All safety devices function as previously described.

1. Add these values to the available static resistance in the respective Blower Performance Tables.
Economizer2 3
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.

Drive Selection
1. Determine side or bottom supply duct application.
2. Determine desired airflow
3. Calculate or measure the amount of external static pressure.
4. Using the operating point determined from steps 1, 2 & 3, locate this point on the appropriate supply air blower performance
table. (Linear interpolation may be necessary.)
5. Noting the RPM and BHP from step 4, locate the appropriate motor and/or drive on the RPM selection table.
6. Review the BHP compared to the motor options available. Select the appropriate motor and/or drive.
7. Review the RPM range for the motor options available. Select the appropriate drive if multiple drives are available for the
chosen motor.
8. Determine turns open to obtain the desired operation point.
Example
1. 6800 CFM
2. 2.0 iwg
3. Using the supply air blower performance table below, the following data point was located: 1020 RPM & 5.92 BHP.
4. Using the RPM selection table below, Size X and Model Y is found.
5. 5.92 BHP exceeds the maximum continuous BHP rating of the 5.0 HP motor. The 7.5 HP motor is required.
6. 1020 RPM is within the range of the 7.5 HP drives.
7. Using the 7.5 HP motor and drive, 3.5 turns open will achieve 1020 RPM.

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.
