Double Wall Construction – Double-wall construction
is the standard construction of the Eco
powder coated pre-fabricated outer panels and corner
post for maximum exterior surface protection.
Factory Shrink-wrap – Eco2 rooftop units are shipped
from the factory with factory-fresh shrink-wrap packaging. No longer does the contractor need to worry about
dirt and debris clogging up condenser coils or moisture
leaking into the air handler on the units way to the job
site or rigging yard.
Copper Fins – For more extreme climates that aggressively can attack aluminum, copper tube evaporator coils
with copper fi ns are available. (This is not recommended
for units in areas where they may be exposed to acid
rain or environments where ammonia is present)
CONDENSER FEATURES AND OPTIONS
Scroll Compressors – Reliable, effi cient, trouble-free
operation is the true measure of a packaged rooftop’s
value. That’s why YORK Eco2 Packaged Rooftop
Air Conditioners use established scroll compressor
technology to deliver dependable, economical performance in a wide range of applications. With the
Eco2 Packaged Rooftop, you get the latest generation
of compressor enhancements added to the scroll’s
inherent strengths. The simplicity of a hermetic scroll
compressor allows the use of fewer moving parts to
minimize breakdown.

and incorporates
Condenser Fan Motors – The condenser fan motors
used on the Eco2 unit are Totally Enclosed Air Over
(TEAO) to provide maximum durability through any
season.
Hot Gas Bypass – This options permits continuous,
stable operation at capacities below the minimum step
of unloading by introducing an artifi cial load on the
evaporator. For models YPAL050-061, it is used on the
lead circuit and standard on VAV units.
Replaceable Core Liquid Line Driers – Liquid line
driers are standard on the Eco2 rooftop unit. An option
is provided for replaceable core driers.

rain or environments where ammonia is present)
Pre-Coated Fins – An epoxy-coated aluminum fi n stock
to guard from corrosive agents and insulate against
galvanic potential. Recommended for mild seashore or
industrial locations.
Post-Coated Fins – Technicoat coil-coating process
used on condenser coils for seashore and other corrosive applications (with the exception of strong alkalis,
oxidizers, wet bromide, chlorine and fl uorine in concen-
trations greater than 100ppm).
Compressor Sound Blankets – Optional compressor
acoustic sound blankets are available for sound sensitive applications.
Multiple Compressor Staging – Through the use of the
scroll compressor, the Eco2 has the ability to stage its
cooling by enabling and disabling multiple single stage
compressors on multiple circuits. These compressors
are manifolded together in pairs on a single refrigeration circuit.
Compressor Circuiting – the Eco2 is designed so that
only 2 scroll compressors are in tandem within one refrigeration circuit. This means more reliable compressors,
and less equipment down time. With multiple circuits, if
a compressor should ever fail on one circuit, the other
circuit will remain operational to work to maintain occupied loads. The Eco2 system has 2 circuits in a unit.

GENERAL
2
The Eco
air conditioning units are designed for outdoor
installation. When selecting a site for installation, be
guided by the following conditions:
• Unit must be installed on a level surface.
• For the outdoor location of the unit, select a place
having a minimum sun exposure and an adequate
supply of fresh air for the condenser.
• Also avoid locations beneath windows or between
structures.
• Optional condenser coil protection should be used
for seashore locations or other harsh environments.
• The unit should be installed on a roof that is structur-
ally strong enough to support the weight of the unit
with a minimum of defl ection. It is recommended that
the unit(s) be installed not more than 15 feet from
a main support beam to provide proper structural
support and to minimize the transmission of sound
and vibration. Ideally, the center of gravity should
be located over a structural support or building
column.
• Location of unit(s) should also be away from build-
ing fl ue stacks or exhaust ventilators to prevent
possible reintroduction of contaminated air through
the outside air intakes.
• Be sure the supporting structures will not obstruct
the duct, gas or wiring connections.
• Proper service clearance space of 6-feet around
the perimeter of the unit, 8-feet on one side for coil
servicing, and 12-feet to any adjacent units is required to eliminate cross contamination of exhaust
and outdoor air, and for maintenance tasks such
as coil pull and cleaning. No obstructions should
be above the condensing unit section.
LOCATION
Of the many factors that can effect the location of
equipment, some of the most important to consider are
Structural, Acoustical and Service clearances. Proper
attention should be made at the design stage to ensure
proper structural support. In cases where equipment is
being replaced, be aware of building design to insure
support is adequate for the application.
The next most important consideration in applying roof
top equipment is that of sound from the equipment.
Special care should be made to keep the roof top unit
away from sound sensitive areas such as conference
rooms, auditoriums and executive offi ces and any other
room that may have potential for tenant occupancy . Possible locations could be above hallways, mechanical or
utility rooms.
8
Finally, service clearances should be maintained in
rooftop design to insure safe access to the unit. Unit
clearances are designed so that technicians have
enough space between units, building walls, and edges
of building to gain access safely . In cases where space
is limited, please call your local YORK representative
for additional information.

NOTE:
1. Under certain conditions these clearances may be encroached upon.
2. This is a visual reference for all Eco

units.
LD08044
RIGGING
Proper rigging and handling of the equipment is mandatory during unloading and setting it into position to retain
warranty status.
Spreader bars must be used by cranes to prevent damage to the unit casing. All lifting lugs must be used when
lifting the rooftop unit. Fork lifts will damage the rooftop
unit and are not recommended. Care must be taken to
keep the unit in the upright position during rigging and
to prevent damage to the watertight seams in the unit
casing. Avoid unnecessary jarring or rough handling.
UNIT PLACEMENT
• Elevated – Elevated roof curbs or dunnage steel
can be used to support the unit in order to raise it
to specifi c heights. When this type of placement
is required, be sure to keep unit access in mind.
Cat-walks or other forms of unit access may be
required to one or both sides of the unit, depending on your area of the country and the local codes
that are enforced. Please check with local offi cials
to ensure the application conforms to local codes
and regulations.
• Ground Level Locations – It is important that the
units be installed on a substantial base that will not
settle, causing strain on the refrigerant lines and
sheet metal and resulting in possible leaks. A onepiece concrete slab with footers extended below
the frost line is highly recommended. Additionally,
the slab should be isolated from the main building
foundation to prevent noise and vibration transmission to the building structure. For ground level
installations, precautions should be taken to protect
the unit from tampering by , or injury to, unauthorized
JOHNSON CONTROLS

persons. Erecting a fence around the unit is common
practice.
• Roof curb – YORK offers optional roof curbs
2
designed specifi cally for the Eco
footprint. This
curb comes as an open condenser model and is
shipped disassembled and requires fi eld assem-
bly and installation. For bottom supply and return
openings, the curbs have matching connections to
ease installation. A pipe chase that matches the
rooftop unit pipe chase is also included in the curb
footprint for through-the-curb utility connections.
The curb should be located according to the location recommendations above, and properly sealed
to prevent moisture and air leakage into and out of
the duct system. Flexible collars should be used
when connecting the duct work to prevent unit noise
transmission and vibration into the building.
Duct work should be supported independently of the unit.

UNIT ORIENTATION
For applications with multiple rooftop units located in
close proximity on the roof, the orientation of the unit
may be important to reduce the potential for re-entrainment of outside airfl ow. Regardless of the outside air and
exhaust air openings on a unit, all rooftop applications
can permit recirculation of exhaust air to the return, if
applied improperly.
HORIZONT AL APPLICATIONS
The spectrum of applications for roof top units in today’s
market is continuing to grow wider by the day. Flexibility in unit design and construction is a must in today’s
market in order to insure safe and sound applications of
HV AC equipment. The Eco2 has been designed for specifi c application of horizontal supply and return airfl ow
taking the guess work out of unit application by building
a unit specifi c to these needs. If the application calls for
horizontal supply and return air, YORK can ship it from
the factory as a horizontal unit. This option elevates the
need for fi eld modifi cation of equipment, saving time
and money . The Eco2 can support a left discharge on all
units except 1,125 MBH gas, and/or right discharge on
all cooling-only units. Return air can be brought through
the end or side return air inlet making the unit specifi c
to building needs.

DUCT CONSIDERATIONS
Unlike competitive units where air can leave the rooftop
unit stratifi ed across the width of the unit, the Eco2 unit
suffi ciently mixes airfl ow to ensure consistent air tem-
perature from the unit. No special T ee considerations are
required and the unit may be oriented either way.
ECONOMIZER
The economizer section is used for ventilation of the
conditioned space to maintain indoor air quality, and
also to reduce energy consumption by using outdoor
air cooling in lieu of mechanical cooling. If outdoor air is
appropriate for cooling, but not suffi cient for the cooling
demand, mechanical cooling will stage on as necessary
until the cooling load is met.
Dual (comparative or differential) enthalpy operation is
the most accurate and effi cient means of economizer
operation. The unit controller monitors the return and
outside air energy content, and selects the lower of the
two for operation.

VAV SUPPLY AIR PRESSURE CONTROL
Traditional packaged rooftop systems use inlet guide
vanes (IGVs) for duct static pressure control. These
control supply duct pressure by modulating dampers
(introducing losses and ineffi ciencies) on the inlet of the
fan, open and closed. YORK’s variable frequency drives
(VFDs) offer superior fan speed control and quieter,
energy effi cient operation.

For V AV applications, the YORK Eco

operation of the unit at part load, and offer the additional
benefi ts of quieter and more effi cient operation when
compared to IGV.
unit uses a VFD
potential. It is used for mild seashore or industrial
locations. This can provide corrosion resistance
comparable to copper fi n coils in typical seashore
locations.
• Post-Coated Condenser Fins – Technicoat (a
post-coated application of epoxy) can be used for
seashore and other corrosive applications with the
exception of strong alkaloides, oxidizers, wet bromide, chlorine and fl uorine in concentrations greater
than 100 ppm. Any of the above suitable options
should be selected based on the particular project
design parameters and related environmental factors. The application should be further reviewed and
approved by the consulting engineer or owner based
on their knowledge of the job site conditions.
BUILDING PRESSURE CONTROL SYSTEMS
Building pressure control systems are often necessary when economizers are used to bring in outdoor
air. Without proper building exhaust, the building may
become over pressurized. The pressure control system
maintains the proper building pressure by expelling the
appropriate amount of air from the building.
FIG. 1. TRADITIONAL OVERHEAD VAV AIR
DELIVERY SYSTEM
HARSH ENVIRONMENTS – CONDENSER AND
EVAPORATOR COIL PROTECTION
For harsh environmental conditions such as seashore
applications, YORK offers three types of coil protection:
copper fi n material, black fi n and Technicoat coatings.
YORK recommends that for corrosive environments that
copper fi ns be used to protect the evaporator and/or
condenser coils. In areas where chemicals that can
corrode copper are present, such as ammonia, YORK
recommends that the black fi n or T echnicoat coating be
used for maximum protection.
• Copper-Fin Evaporator and Condenser Coil
– Copper fi ns can be used instead of aluminum for
additional corrosion protection. However, it is not
suitable for areas that are subject to acid rain or
exposed to ammonia.
• Pre-Coated Condenser Fins – Black fi n coating
(yellow fi n for evaporator fi ns) is pre-coated appli-
cation epoxy on aluminum fi n stock to guard from
corrosive agents and insulate against galvanic
Exhaust/relief fans – In this application, a powered
exhaust fan may be suitable, however careful consideration of the fan type is necessary. YORK offers a
centrifugal powered exhaust fan to perform this function.
Some manufacturers use a propeller exhaust fan, which
cannot handle the static pressure requirements.
For systems with moderate to low return static pressure,
an exhaust fan is recommended. The benefi t of the ex-
haust fan is that it does not run all of the time, and may
facilitate compliance with the ASHRAE 90.1 fan motor
horsepower requirement.
The exhaust fan operates in parallel with the supply
fan. In this arrangement, the supply fan handles the full
static pressure requirements of the system. For normal
building pressure control, the exhaust fan operates to
draw air from the return plenum and exhaust it out of
the building.
The exhaust fan confi guration is available in two forms,
modulating and non-modulating. Modulating is the most
common and recommended for the majority of applications, while non-modulating should be used with in only
certain circumstances.
In the modulating exhaust system, the volume of airfl ow
exhausted from the building is proportional to the entering volume of outside air. Control is accomplished via
either a discharge damper or a variable-frequencydrive
(VFD). YORK recommends the use of a VFD to reduce
energy consumption, sound levels and improved reliability due to fewer moving parts.
10
JOHNSON CONTROLS
Page 11
FORM 100.50-EG5 (108)
In the non-modulating exhaust system, the exhaust airfl ow is constant whenever the exhaust fan is operating.
This type of control should only be used to either assist
a smoke purge system or when a system requires a
constant volume of exhaust airfl ow.
ACOUSTICAL CONSIDERATIONS
2
The Eco
unit is designed for lower sound levels than
competitive units by using fl exible fan connections, fan
spring isolators, double-wall construction, multiple fan
options, and lower speed and horsepower fans. For
V AV applications, VFDs are used instead of inlet guide
vanes. Additional sound attenuation can be obtained
using compressor sound blankets and fi eld-supplied
sound attenuators when necessary.
Even with these equipment design features, the acoustical characteristics of the entire installation must never be
overlooked. Additional steps for the acoustical characteristics of a rooftop installation should be addressed during
the design phase of a project to avoid costly alterations
after the installation of the equipment. During the design
phase of a project, the designing engineer should consider, at a minimum, the impact of the equipment location,
rooftop installation, building structure, and duct work.

Altitude and Temperature Corrections
The information below should be used to assist in
application of product when being applied at altitudes
at or exceeding 1000 feet above sea level.
The airfl ow rates listed in the standard blower perfor-
mance tables are based on standard air at sea level.
As the altitude or temperature increases, the density
of air decreases. In order to use the indoor blower
tables for high-altitude applications, certain corrections
A centrifugal fan is a “constant-volume” device. This
means that if the RPM remains constant, the CFM delivered is the same regardless of the density of the air.
However, since the air at high altitude is less dense,
less static pressure will be generated and less power
will be required than a similar application at sea level.
Air-density-correction factors are shown in Table 7 and
Figure 2.

Altitude (feet)
The examples below will assist in determining the airfl ow
performance of the product at altitude.
Example 1: What are the corrected CFM, static
pressure, and BHP at an elevation of 5,000 ft. if the
blower performance data is 6,000 CFM, 1.5 IWC and
4.0 BHP?
Solution: At an elevation of 5,000 ft, the indoor blower
will still deliver 6,000 CFM if the RPM is unchanged.
However, Table 7 must be used to determine the static
pressure and BHP.
Since no temperature data is given, we will assume an
air temperature of 70°F. Table 7 shows the correction
factor to be 0.832.
Corrected static pressure = 1.5 x 0.832 = 1.248 IWC
Corrected BHP = 4.0 x 0.832 = 3.328
Example 2: A system, located at 5,000 feet of elevation,
is to deliver 6,000 CFM at a static pressure of 1.5”. Use
the unit blower tables to select the blower speed and
the BHP requirement.
Solution: As in the example above, no temperature
information is given so 70°F is assumed.
The 1.5" static pressure given is at an elevation of
5,000 ft. The fi rst step is to convert this static pressure
to equivalent sea-level conditions.
Sea-level static pressure = 1.5 / 0.832 = 1.80"
Enter the blower table at 6000 sCFM and static pressure
of 1.8”. The RPM listed will be the same RPM needed
at 5,000 ft.
Suppose that the corresponding BHP listed in the blower
table is 3.2.
This value must be corrected for elevation.
BHP at 5,000 ft = 3.2 x .832 = 2.66

ELECTRICAL SERVICE SIZING
In order to use the electrical service required for the cool-
2
ing-only Eco
rooftop, use the appropriate calculations
listed below from U.L. 1995. Based on the confi guration
of the rooftop, the calculations will yield different MCA
(minimum circuit ampacity), and MOP (maximum overcurrent protection).
Using the following load defi nitions and calculations,
determine the correct electrical sizing for your unit. All
concurrent load conditions must be considered in the
calculations, and you must use the highest value for any
combination of loads.
Load Defi nitions:
• LOAD1 is the current of the largest motor – com-
pressor or fan motor.
• LOAD2 is the sum of the remaining motor currents
that may run concurrently with LOAD1.

• LOAD3 is the current of the electric heaters – zero
for cooling-only units.
• LOAD4 is the sum of any remaining currents greater
than or equal to 1.0 amp.
Use the following calculations to determine MCA and
MOP for units supplied with a single-point power connection:
MCA = (1.25 x LOAD1) + LOAD2 + LOAD3 + LOAD4
MOP = (2.25 x LOAD1) + LOAD2 + LOAD3 + LOAD4
If the MOP does not equal a standard current rating
of an overcurrent protective device, then the marked
maximum rating is to be the next lower standard rating.
However, if the device selected for MOP is less than the
MCA, then select the lowest standard maximum fuse
size greater than or equal to the MCA.

CONTROL SEQUENCES FOR SIMPLICITY ELITE CONTROLLED UNITS
GENERAL
The control system for the YORK Eco² Packaged
Rooftop Unit is fully self-contained and based around
a Rooftop Unit controller. To aid in unit setup, unit controller is equipped with a user visual LCD interface that
consists of a 2 character above a 4-character display
on the front of the Simplicity Elite control board. The two
digit indicates the parameter of point number, and the
4-digit displays the current value or setting such as time
delay , cooling set point temperature, etc. This interface
provides verifi cation of the systems operating status,
enables fi eld installed options, and aids in troubleshoot-
ing system faults.
Four program buttons, located around the LCDs, allow
the user to view and/or change 89 default parameter
settings, acknowledge 42 alarm codes, and perform a
unit run test. Up to fi ve (5) alarm Codes are displayed
on the 4-character LCD.
Greater access to programming can be gained through
a Palm Pilot or Personal Computer (PC). Additionally,
up to 64 of the Simplicity family of controllers can be
networked together using a 3-conductor shielded cable
to communicate with your PC via the available YORK
recommended FREE net Serial Adapter and free YORK
downloaded software.
An LED located on the lower center of the board provides
a fl ash rate of 1 second (heart beat) when no alarms are
present. A fl ash rate of 250 ms indicated that a current
alarm is present. The LED lights up constantly if the
board has failed and needs replaced, and will not light
when the board power is lost.

tion. Optional BACnet (MSTP) is available with a Modlinc
translator, which allows communication to a BACNet
(MSTP) based BAS.
UNOCCUPIED / OCCUPIED SWITCHING
Depending on application, the unit can be indexed
between unoccupied and occupied modes of operation
by one of three methods: hard-wired input, internal time
clock, or BAS. A contact-closure input is provided for
hard-wiring to an external indexing device such as a
central time clock, thermostat with built-in scheduling,
or a manual switch. The unit controller is also equipped
with a built-in 7-day time clock which can be used, in
lieu of the contact closure input, to switch the unit between Unoccupied and Occupied modes of operation.
The internal time clock is fully confi gurable via the user
interface and includes Holiday scheduling. In addition to
the hard-wired input or the internal time clock, the unit
can also be indexed between unoccupied and occupied
modes of operation via BAS command.
GAS HEATING OPERATION
Units supplied with gas heat can be equipped with one,
two, or three independently operated burner modules.
Each module is a fully self-contained furnace with all
necessary ignition controls, safeties, and gas valves.
The rooftop Unit Controller determines how the furnaces
are started and stopped and prevents furnace operation
if the Supply Fan airfl ow is not suffi cient or if the Supply
Air Temperature is excessively high.
If a furnace module receives a signal to start from the
Unit Controller, the ignition control engages the furnace
inducer (draft) fan for a 30-second pre-purge cycle. At
the end of the 30-second pre-purge, the ignition control
will stop the furnace and allows the inducer fan to operate for a 30-second post-purge. Each furnace contains
a direct-spark-ignition system and includes safeties for
fl ame and inducer fan verifi cation, high temperature and
fl ame roll-out.
MORNING WARM-UP
For the maximum in system fl exibility, the YORK Eco²
Packaged Rooftop Unit can be operated by either a
typical 7-wire thermostat (2 cool/2 heat), a space temperature sensor, or stand-alone (V A V only). Note, a fi eld
wiring terminal block is provided to facilitate unit setup
and installation.
In lieu of the hard-wired control options, the rooftop
unit controller can be connected to and operated by a
Building Automation System (BAS). The Rooftop Unit
controller is equipped with a Modbus (RTU) communica-
28
Morning Warm-Up can be initialized by BAS or by the
Unit Controller if the Intelli-Start is used. If the Intelli-Start
is used, the Morning Warm-Up start time is calculated
through an adaptive algorithm.
When Morning Warm-Up is required, the Unit Controller
energizes the V A V heat relay , starts the Supply Fan and
qualifi es the Return Air Temperature for 5 minutes.
The internal heat source (Gas, HW/Steam, or Electric)
is controlled to maintain the Return Air Temperature to
JOHNSON CONTROLS
Page 29
FORM 100.50-EG5 (108)
the Return Air Temperature Setpoint, Morning WarmUp ends when occupancy occurs (BAS, Intelli-Start, or
contact closure), or when the Maximum Morning WarmUp Time has expired.
ECONOMIZER OPERATION
The unit can be equipped with one of three types of
optional economizers: dry-bulb, single-enthalpy , or comparative-enthalpy. When the unit controller determines
that Outside Air is suitable for economizing, the unit
controller will control the outside air damper(s) open
to provide economizer cooling. If economizer cooling
alone is insuffi cient for the cooling load, the unit control-
ler shall stage up compressors, one at a time, to meet
demand.
The control logic for the three types of economizers is
as follows:
Dry-Bulb Economizer
The dry-bulb economizer is the default economizer
control scheme. With the dry-bulb economizer, the unit
controller monitors the Outside Air temperature only
and compares it to a reference temperature setting.
Outside Air is deemed suitable for economizing when
the Outside Air temperature is determined to be less
than the reference temperature setting. This method of
economizing is effective, but is prone to some changeover ineffi ciencies due to the fact that this method is
based on sensible temperatures only and does not take
Outside Air moisture content into consideration.
Single-Enthalpy Economizer
perature is less than the reference temperature setting.
This method of economizing is the most accurate and
provides the highest degree of energy effi ciency for a
packaged rooftop economizer.
VENTILATION CONTROL SEQUENCES
Minimum OA Damper Position (CV Units)
When the unit goes into the Occupied mode of operation,
the unit controller shall open the Outside Air Damper to
a fi xed minimum position. The damper shall remain at
this position as long as the unit is in the occupied mode,
and the economizer is not suitable for cooling.
Minimum OA Damper Position (VAV Units)
With Variable Air Volume units, there are two Minimum
OA Damper Positions: one when the unit is at full speed
and the second when the unit is at approximately half
speed. These two points allow the control to linearly
reset the position of the OA damper in response to fan
speed.
When the unit goes into the Occupied mode of operation,
the unit controller shall monitor the speed of the supply
fan and open the Outside Air damper to a calculated
minimum position based on the fan speed. This minimum
position shall vary as the speed of the fan changes. The
damper shall remain at this calculated position as long
as the unit is in the occupied mode, and the economizer
is not suitable for cooling.
EXHAUST CONTROL SEQUENCES
With the optional, single-enthalpy economizer, the unit
controller monitors the Outside Air enthalpy in addition
to the Outside Air temperature and compares it to a
reference enthalpy setting and a reference temperature
setting. Outside Air is deemed suitable for economizing
when the Outside Air enthalpy is determined to be less
than the reference enthalpy setting and the Outside Air
temperature is less than the reference temperature setting. This method of economizing allows the reference
temperature setting to be set higher than the dry-bulb
Economizer and is a more effi cient packaged rooftop
economizer.
Dual-Enthalpy Economizer
With the optional, dual-enthalpy economizer, the unit
controller monitors and compares the Outside Air and
Return Air enthalpies, in addition to comparing the
Outside Air temperature to the reference temperature
setting. Outside Air is deemed suitable for economizing
when the Outside Air enthalpy is determined to be less
than the Return Air enthalpy and the Outside Air tem-
JOHNSON CONTROLS
Barometric
The optional barometric exhaust system consists of a
lightweight barometric relief damper installed on the end
of the unit in the Return Air section. As more outside air
is introduced into the controlled zone due to Economizer
and Ventilation control sequences, the pressure inside
the building rises. As building static pressure increases
to overcome any exhaust duct static pressure, air will be
allowed to escape through the barometric relief damper.
Because this type of exhaust is not powered, the amount
of air exhausted will be limited to the static pressure that
will need to be overcome.
Powered, Variable-Volume Exhaust-Discharge
Damper Controlled
This optional variable-volume, powered-exhaust system
consists of a fi xed-speed fan confi gured with a propor-
tionally controlled discharge damper. The Rooftop Unit
controller monitors the pressure inside the building and
controls the Exhaust Damper and the Exhaust Fan.
If the Building Pressure rises, the Exhaust Damper is
29
Page 30
Controls (continued)
FORM 100.50-EG5 (108)
proportionally controlled open and the Exhaust Fan is
controlled ON. If the Building Pressure falls, the Exhaust
Damper is proportionally controlled closed and the Exhaust Fan is controlled OFF . The position of the Exhaust
Damper in which the Exhaust Fan is controlled ON and
OFF as well as the Building Pressure setpoint are userselectable from the Rooftop Unit User Interface.
Powered, Variable-Volume Exhaust-VFD
Controlled
This optional variable-volume, powered-exhaust system
consists of an Exhaust Fan driven by a Variable Frequency Drive (VFD), which is controlled by the Rooftop
Unit controller. The Rooftop Unit controller monitors the
pressure within the building. As the pressure rises, the
VFD is controlled to increase Exhaust Fan speed. As
the pressure falls, the VFD is controlled to decrease
Exhaust Fan speed. The Building Pressure Setpoint is
user-selectable from the Rooftop Unit User Interface.
On/Off control is maintained the same as Exhaust-Discharge Damper control stated above.
LOW-AMBIENT/HEAD-PRESSURE CONTROL
OPERATION
SMOKE PURGE SEQUENCE
A contact closure input (PURGE) is provided to place the
unit in smoke purge mode. When the contact is closed
the unit will operate as follows:
• Turn off all heating and cooling operation
• Set the outdoor air damper output to 100%
• Close the return to 0%
• Turn the supply fan on
• On VAV unit set the supply fan output to 100%.
• Turn the power exhaust fan on
• On VFD driven exhaust fans set the exhaust fan
output to 100%
Note that 24 volts terminal (R) on the Simplicity control
board must be used as the 24 Volt AC source for switch
the contact to the Unit Controller Smoke Purge (PURGE)
input. Use of any power source external to the controller
will result in damage to the Unit Controller.
VAV SPECIFIC SEQUENCES
SUPPLY FAN OPERATION
The Rooftop Unit controller continuously monitors the
outside air temperature to determine if mechanical cooling should be allowed. As a safety, if the Outside Air
temperature falls to or below the Low Ambient Lockout
temperature, mechanical cooling is prevented from
operating.
For units with economizers, the Low Ambient Lockout
temperature is typically low enough that mechanical
cooling will rarely be required. However, for some applications, mechanical cooling is required when the
Outside Air temperature is lower than the Low Ambient
Lockout temperature.
For these applications, the unit must be equipped with
optional Low Ambient controls. For optional Low Ambient operation, the Rooftop Unit controller monitors the
refrigeration-system discharge pressure and controls the
speed of the fi rst stage condenser fan. If the discharge
pressure falls, the speeds of the condenser fan is reduced to maintain acceptable condensing pressures in
the refrigeration system. With the optional Low Ambient
controls, mechanical cooling is allowed down to Outside
Air temperatures of 0°F.
For V A V units, the supply fan is controlled ON and OFF
based on the occupancy state. When the unit goes
into the Occupied mode of operation, the Rooftop Unit
controller will monitor the static pressure within the
supply-duct system and control the speed of the supply
fan to maintain a specifi ed Duct Static Pressure setpoint.
A Variable Frequency Drive (VFD) is used on all VAV
units to vary the speed of the supply fan. Note, the use
of a VFD in lieu of inlet guide vanes provides for higher
energy effi ciency for the unit by eliminating the losses
(air-pressure drop) typical of inlet guide vane systems.
