ductwork, it should be mounted on the return air duct.  
Features and Benefits  
Standard Features  
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  
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.  
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. Crankcase heaters are  
standard on reciprocating compressors. Scroll compressors  
do not require crankcase heaters. Phase Monitors are  
standard on units with scroll compressors. This accessory  
monitors the incoming power to the unit and protects the  
unit from phase loss and reversed phase rotation.  
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.  
Advanced Controls - Simplicity™ ZJ/ZR/ZF control  
boards have standardized a number of features  
previously available only as options or by utilizing  
additional controls.  
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.  
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  
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.  
temperature is low or when free cooling is available.  
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.  
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  
BAS Controls - York’s Sunline™ series units offer factory  
®
mounted BAS controls such as Simplicity Intelli-  
Comfort, 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.  
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.  
Factory Mounted Outdoor Air Dampers - All models are  
available with these "factory mounted" outdoor air damper  
options:  
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.  
• Single enthalpy economizer with or without power  
exhaust  
• BAS-ready economizer with or without power exhaust  
• Motorized outdoor air damper  
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.  
• 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,  
Safety Monitoring - The control board monitors the  
high and low-pressure switches, the freezestats, the gas

be field-assembled before installing.  
gas and electric heat units. The unit control board will  
alarm on ignition failures, compressor lockouts and  
repeated limit switch trips.  
• 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.  
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.  
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.  
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.  
For units with optional VAV or Simplicity® Intelli-  
Comfort™ 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).  
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.  
The rainhood 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.  
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.  
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.  
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.  
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.  
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.  
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.  
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.

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.  
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.  
York Commercial Comfort System (YCCS) - Provides  
rooftop system integration for YCCS single zone, change-  
over 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.  
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.  
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.  
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

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.  
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.  
“Normal” 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.  
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.  
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".  
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  
The unit will not operate in the reheat mode if there is any call  
for heating.

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.

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.

1. These values have been accessed using a model of sound propagation from a point source into the hemispheric/free field. The dBA values  
provided are to be used for reference only. Calculation of dBA values cover matters of system design and the fan manufacturer has no way  
of knowing the details of each system. This constitutes an exception to any specification or guarantee requiring a dBA value of sound data  
in any other form than sound power level ratings.
