FACTORY OPTIONS AND/OR ACCESSORIES
2−Speed VFD Drive Motor
The 2−speed VFD drive motor system saves energy and
installation time by utilizing a Variable Frequency Drive (VFD) to
automatically adjust the indoor fan motor speed in sequence
with the units cooling operation. Per ASHRAE 90.1 2010
standard section 6.4.3.10.b, during the first stage of cooling
operation the VFD will adjust the fan motor to provide 2/3rd of
the total cfm established for the unit. When a call for the second
stage of cooling is required, the VFD will allow the total cfm for
the unit established (100%). During the heating mode the VFD
will allow total design cfm (100%) operation and during the
ventilation mode the VFD will allow operation to 2/3rd of total
cfm.
Compared to single speed indoor fan motor systems, 2 speed
system can save substantial energy, 25%+, versus single speed
indoor fan motor systems.
The VFD used in the system has soft start capabilities to slowly
ramp up the speeds, thus eliminating any high in rush air volume
during initial start−up. It also has internal over−current protection
4
for the fan motor and a field installed display kit that allows
adjustment and in depth diagnostics of the VFD.
This system is available on models with 2−stage cooling
operation with electro−mechanical controls. Both space sensor
and conventional thermostats/controls can be used to provide
accurate control in any application.
The system is very flexible for initial fan performance set up and
adjustment. The standard factory shipped VFD is
pre−programmed to automatically stage the fan speed between
the first and second stage of cooling. The unit fan performance
static pressure and cfm can be easily adjusted using the
traditional means of pulley adjustments. The other means to
adjust the unit static and cfm performance is to utilize the field
installed Display Kit and adjust the frequency and voltage in the
VFD to performance requirements. In either case, once set up,
the VFD will automatically adjust the speed between the cooling
stage operations.

Economizer
Economizers save energy, money and improve comfort levels in
the conditioned space: They bring in fresh, outside air for
ventilation; and provide cool outside air to cool your building.
This also is the preferred method of low ambient cooling. When
integrated with CO2 sensors, economizers can provide even
more savings by coupling the ventilation air to only that amount
required based on space occupancy.
Economizers are available, installed and tested by the factory,
with either enthalpy or temperature dry − bulb inputs. There are
also models for electromechanical and single speed fan or 2
speed indoor fan motors. Additional sensors are available as
accessories to optimize the economizer. Economizers include
gravity controlled barometric relief that helps equalize building
pressure and ambient air pressures. This can be a cost effective
solution to prevent building pressurization.
Economizers are available in Ultra Low Leak and standard low
leak versions.
CO2 Sensor
Improves productivity and saves money by working with the
economizer to intake only the correct amount of outside air for
ventilation. As occupants fill your building, the CO2 sensor
detects their presence through increasing CO2 levels, and opens
the economizer appropriately.
When the occupants leave, the CO2 levels decrease, and the
sensor appropriately closes the economizer. This intelligent
control of the ventilation air, called Demand Control Ventilation
(DCV) reduces the overall load on the rooftop, saving money.
CO2 sensors are available with the economizer, installed and
tested by the factory.
Smoke Detectors
Smoke detectors immediately shut down the rooftop unit when
smoke is detected. Supply air smoke detectors are available,
installed by the factory.
Louvered Hail Guards
Sleek, accessory louvered panels protect the condenser coil
from hail damage, foreign objects, and incidental contact.
Convenience Outlet (un−powered)
Lower service bills by including a convenience outlet in your
specification. Provides a convenient, 15 amp, 115v GFCI
receptacle.
Non−fused Disconnect
This OSHA−compliant, factory−installed, safety switch allows a
service technician to locally secure power to the rooftop.
Barometric Relief
Gravity controlled, barometric relief equalizes building pressure
and ambient air pressures. This can be a cost effective solution
to prevent building pressurization.
Power Exhaust
Superior internal building pressure control. This field−installed
accessory may eliminate the need for costly, external pressure
control fans.
Time Guard II Control Circuit
This accessory protects your compressor by preventing
short−cycling in the event of some other failure, prevents the
compressor from restarting for 30 seconds after stopping. Not
required with authorized commercial thermostats.
Motorized 2−Position Damper
A 2−position, motorized outdoor air damper is available factory
installed and admits up to 100% outside air. Using reliable,
gear−driven technology, the 2−position damper opens to allow
ventilation air and closes when the rooftop stops, stopping
unwanted infiltration.
Manual OA Damper
Accessory manual outdoor air dampers are an economical way
to bring in ventilation air.
Head Pressure Controller
The motor controller is a low ambient, head pressure controller
kit that is designed to maintain the unit’s condenser head
pressure during periods of low ambient cooling operation. This
device should be used as an alternative to economizer free
cooling not when economizer usage is either not appropriate or
desired. The controller will either cycle the outdoor−fan motors
or operate them at reduced speed to maintain the unit operation,
depending on the model.
509 11 3510 00
Winter Start Kit
The accessory winter start kit extends the low ambient limit of
your rooftop to 25F (−9C). The kit bypasses the low pressure
switch, preventing nuisance tripping of the low pressure switch.
Other low ambient precautions may still be prudent.
Liquid Propane Heating
Convert your gas heat rooftop from standard natural gas
operation to liquid propane using this field−installed kit.
High Altitude Heating
High altitudes have less oxygen, which means heat exchangers
need less fuel. The new gas orifices in this field−installed kit
make the necessary adjustment for high altitude applications.
They restore the optimal fuel to air mixture and maintain healthy
combustion at altitudes above 2000 ft (610m). Kits may not be
required in all areas.
Flue Discharge Deflector
The flue discharge deflector is a useful accessory when flue gas
recirculation is a concern. By venting the flue discharge
upwards, the deflector minimizes the chance for a neighboring
unit to intake the flue exhaust.
Stainless Steel Heat Exchanger (Optional)
The stainless steel heat exchanger option provides the tubular
heat exchanger be made out of a minimum 20 gage type 409
stainless steel for applications where the mixed air to the heat
exchanger is expected to drop below 45F (7C). Stainless steel
may be specified on applications where the presence of airborne
contaminants require its use ( applications such as paper mills )
or in areas with very high outdoor humidity that may result in
severe condensation in the heat exchanger during cooling
operation.
Flue Discharge Heat Shield
The flue discharge heat shield keeps people from touching the
rooftop unit’s potentially hot flue discharge. This is especially
useful for ground level applications, where more, untrained
people could have access to the unit’s exterior.
Alternate Motors and Drives
Some applications need larger horsepower motors, some need
more airflow, and some need both. Regardless of the case, your
unit has a factory installed combination to meet your application.
A wide selection of motors and pulleys (drives) are available,
factory installed, to handle nearly any application.
Thru−the−Base Connections
Thru−the−base connections, available as accessory, are
necessary to ensure proper connection and seal when routing
wire and piping through the rooftop’s basepan and curb. These
couplings eliminate roof penetration and should be considered
for gas lines, main power lines, as well as control power.
Supply Duct Cover
This supply duct cover is required when field converting the
factory standard vertical duct supply to horizontal duct supply
configuration. One required per unit. (180 size only)
Optional Hot Gas Reheat System
The Hot Gas Reheat System is an all−inclusive factory−installed
option that can be ordered with any 3 phase RGS unit.
This system expands the envelope of operation of our rooftop
products to provide unprecedented flexibility to meet year−round
comfort conditions.
The Hot Gas Reheat System has the industry’s only dual
dehumidification mode setting. The Hot Gas Reheat System
includes two new modes of operation.
The RGS rooftop coupled with the Hot Gas Reheat system is
capable of operating in normal design cooling mode, subcooling
mode, and hot gas reheat mode. Normal design cooling mode is
when the unit will operate under its normal sequence of
operation by cycling compressors to maintain comfort
conditions.
Subcooling mode will operate to satisfy part load type conditions
when the space requires combined sensible and a higher
proportion of latent load control. Hot Gas Reheat mode will
operate when outdoor temperatures diminish and the need for
latent capacity is required for sole humidity control. Hot Gas
Reheat mode will provide neutral air for maximum
dehumidification operation.
Hinged Access Panels
Allows access to unit’s major components with specifically
designed hinged access panels. Panels are: filters, control box,
fan motor and compressor.

NOTE:
1. Heat ratings are for natural gas heat exchangers operated at or below 2000 ft. For information on LP or altitudes above 2000 ft
(610m), see the Application Data section of this book. Accessory LP/High Altitude kits are also available.
2. In the USA the input rating for altitudes above 2000 ft (610m) must be derated by 4% for each 1000 ft (305 m) above sea level. In
Canada, the input rating must be derated by 10% for altitudes of 2000 ft (610 m) to 4500 ft (1372 m) above sea level.

NOTES:
1. Outdoor sound data is measure in accordance with AHRI
standard 270−95.
2. Measurements are expressed in terms of sound power. Do
not compare these values to sound pressure values because
sound pressure depends on specific environmental factors
which normally do not match individual applications. Sound
power values are independent of the environment and therefore
more accurate.
3. A−weighted sound ratings filter out very high and very low
frequencies, to better approximate the response of “average”
human ear. A−weighted measurements are taken in accordance
with AHRI standard 270−95.

APPLICATION DATA
Min operating ambient temp (cooling):
Propane heating:
In mechanical cooling mode, your rooftop can safely operate
down to an outdoor ambient temperature of 25F (−4C), with
an accessory winter start kit; 40F (4C) standard min operating
temperature. It is possible to provide cooling at lower outdoor
ambient temperatures by using less outside air, economizers,
and/or accessory low ambient kits.
Liquid propane (LP) has different physical qualities than natural
gas. As a result, LP requires different fuel to air mixture. To
optimize the fuel/air mixture for LP, different burner orifices in an
easy to install accessory kits are available from your distributor.
To select the correct burner orifices or determine the heat
capacity for an LP application the selection software, or the
unit’s service manual.
Max operating ambient temp (cooling):
The maximum operating ambient temperature for cooling mode
is 115F (46C). While cooling operation above 115F (46C)
may be possible, it could cause either a reduction in
performance, reliability, or a protective action by the unit’s
internal safety devices.
Min mixed air temp (heating):
Using the factory settings, the minimum temperatures for the
mixed air (the combined temperature of the warm return air and
the cold outdoor air) entering the dimpled, gas heat exchangers
are:
Aluminized
50F (10C) continuous
Stainless Steel
40F (4C) continuous
45F (7C) intermittent
35F (2C) intermittent
Operating at lower mixed−air temperatures may be possible, if a
field−supplied, outdoor air thermostat initiates both heat stages
when the temperature is less than the minimum temperatures
listed above. Please contact your local representative for
assistance.
Min and max airflow (heating and cooling):
To maintain safe and reliable operation of your rooftop, operate
within the heating airflow limits during heating mode and cooling
airflow limits during cooling mode. Operating above the max
may cause blow−off, undesired airflow noise, or airflow related
problems with the rooftop unit. Operating below the min may
cause problems with coil freeze−up and unsafe heating
operation. Heating and cooling limitations differ when evaluating
operating CFM, the minimum value is the HIGHER of the cooling
and heating minimum CFM values published in Table 7 and the
maximum value is the LOWER of the cooling and heating
minimum values published in Table 7.
Heating−to−cooling changeover:
Your unit will automatically change from heating to cooling mode
when using a thermostat with an auto−change−over feature.
Airflow:
All units are draw−though in cooling mode and blow−through in
heating mode.
Outdoor air application strategies:
Economizers reduce operating expenses and compressor run
time by providing a free source of cooling and a means of
ventilation to match application changing needs. In fact, they
should be considered for most applications. Also, consider the
various economizer control methods and their benefits, as well
as sensors required to accomplish your application goals.
Please contact your local sales representative for assistance.
Motor limits, break horsepower (BHP):
Due to the internal unit design, air path, and specially designed
motors, the full horsepower (maximum continuous BHP) band,
as listed in Table 8, 10, and 11, can be used with the utmost
confidence. There is no need for extra safety factors, the motors
are designed and rigorously tested to use the entire, listed BHP
range without either nuisance tripping or premature motor
failure.
34
High altitude heating:
High altitudes have less oxygen, which affects the fuel/air
mixture in heat exchangers. In order to maintain a proper fuel/air
mixture, heat exchangers operating in altitudes above 2000 ft
(610m) require different orifices. To select the correct burner
orifices or determine the heat capacity for a high altitude
application either the selection software, or the unit’s service
manual.
High altitudes have less oxygen, which means heat exchangers
need less fuel. The new gas orifices in this field−installed kit
make the necessary adjustment for high altitude applications.
They restore the optimal fuel to air mixture and maintain healthy
combustion on altitudes above 2000 ft (610m).
NOTE: Typical natural gas heating value ranges from 975 to
1050 Btu/ft3 at sea level nationally. The heating value goes down
approximately 1.7% per every thousand feet elevation. Standard
factory orifices can typically be used up to 2000 ft (610m)
elevation without any operational issues.
NOTE: For installations in Canada, the input rating should be
derated by 10% for altitudes from 2000 ft (610m) to 4500 ft
(1372m) above sea level.
Sizing a rooftop
Bigger isn’t necessarily better. While an air conditioner needs to
have enough capacity to meet the design loads, it doesn’t need
excess capacity. In fact, excess capacity typically results in very
poor part load performance and humidity control.
Using higher design temperatures than ASHRAE recommends
for your location, adding “safety factors” to the calculated load,
are all signs of oversizing air conditioners. Oversizing the air
conditioner leads to short cycling ( quick on−off cycles ) which
results in poor humidity control, reduced efficiency, higher utility
bills, larger indoor temperature swings, excessive noise, and
increased wear and tear on the air conditioner.
Rather than oversizing an air conditioner, engineers should
“right−size” or even slightly undersize air conditioners. Correctly
sizing an air conditioner controls humidity better; promotes
efficiency; reduces utility bills; extends equipment life, and
maintains even, comfortable temperatures. Please contact your
local representative for assistance.
Low ambient applications
The optional economizer can adequately cool your space by
bringing in fresh, cool outside air. In fact, when so equipped,
accessory low−ambient kit may not be necessary. In low
ambient conditions, unless the outdoor air is excessively humid
or contaminated, economizer−based “free cooling” is the
preferred less costly and energy conscious method.
In low ambient applications where outside air might not be
desired (such as contaminated or excessively humid outdoor
environments), your rooftop can operate to ambient
temperatures down to −20F (−29C) using the recommended
accessory Motormaster low ambient controller.

2−Speed Indoor Fan Motor System with
Variable Frequency Drive (VFD)
The 2−Speed Indoor Fan Motor System utilizes a Variable
Frequency Drive (VFD) to automatically adjust the indoor
fan motor speed in sequence with the units cooling
operation. Per ASHRAE 90.1 2010 standard section
6.4.3.10.b, during the first stage of cooling operation the
VFD will adjust the fan motor to provide 2/3rd of the total
cfm established for the unit. When a call for the second
stage of cooling is required, the VFD will allow the total
cfm for the unit established (100%). During the heating
mode, the VFD will allow total design cfm (100%)
operation and during the ventilation mode the VFD will
allow operation to 2/3rd of total cfm.
The VFD used in the 2−Speed Indoor Fan Motor System
has soft start capabilities to slowly ramp up the speeds,
thus eliminating any high inrush air volume during initial
start−up. It also has internal over current protection for the
fan motor and a field installed display kit that allows
adjustment and in depth diagnostics of the VFD.
509 11 3510 00
This 2−Speed Indoor Fan Motor System is available on
models with 2−stage cooling operation with electrical
mechanical or RTU Open (multi Protocol) controls. Both
space sensor and conventional thermostats/controls can
be used to provide accurate control in any application.
The 2−Speed Indoor Fan Motor System is very flexible for
initial fan performance set up and adjustment. The
standard factory shipped VFD is pre programmed to
automatically stage the fan speed between the first and
second stage of cooling. The unit fan performance static
pressure and cfm can be easily adjusted using the
traditional means of pulley adjustments. The other means
to adjust the unit static and cfm performance is to utilize
the field installed display module and adjust the frequency
and voltage in the VFD to required performance
requirements. In either case, once set up the VFD will
automatically adjust the speed between the cooling stage
operation.

II.
III.
IV.
Make an initial guess at cooling tons.
Refrig. tons = TCLoad / 12 MBH per ton
Refrig. tons = 72.0 / 12 = 6.0 tons
In this case, start by looking at the RGS072.
Look up the rooftop’s TC and SHC.
Table 18 shows that, at the application’s supply air
CFM, mixed air and ambient temperatures, the
RGS072 supplies:
TC = 73.7 MBH
SHC = 54.3 MBH.
Calculate the building latent heat load.
LHCLoad = TCLoad − SHCLoad
LHCLoad = 72.0 MBH − 54.0 MBH = 18.0 MBH
V.
Calculate RTU latent heat capacity.
LHC = TC − SHC
LHC = 73.7 MBH − 54.3 MBH = 19.4 MBH
VI.
Compare RTU capacities to loads. 2,3
Compare the rooftop’s SHC and LHC to the
building’s sensible and latent heat loads.

Look up the indoor fan RPM & BHP.
Table 39 shows, at 2100 CFM & ESP= 0.8,
RPM = 1358 & BHP = 1.52
X.
Convert BHP (Step VIII) into fan motor heat.
Fan motor heat = 2.546* BHP/Motor Eff.4
Fan motor heat = 4.9 MBH
XI.
Calculate RTU heating capacity.

XII. Select a gas heater.
Table 4 shows the heating capacities of the
RGS072 = 93.0 MBH. Select the RGS072
XIII. Determine electrical requirements.
Table 75 shows the MCA and MOCP of a RGS072
(without convenience outlet) as:
MCA = 30.5 amps & MOCP = 45.0 amps
Min. disconnect size: FLA = 30 & LRA = 157.
NOTES:
1. Selection software saves time by performing many of the
steps above. Contact your sales representative for assistance.
2. Unit ratings are gross capacities and do not include the effect
of evaporator fan motor heat. See Step X. for determining
amount of evaporator fan motor heat to subtract from total and
sensible capacities to obtain net cooling and net sensible
capacities.
3. Selecting a unit with a SHC slightly lower than the SHCLoad is
often better than oversizing. Slightly lower SHC’s will help
control indoor humidity, and prevent temperature swings.
4. Indoor fan motor efficiency is available in Tables 51−67. Use
the decimal form in the equation, eg. 80% = .8.

1.Interpolation is permissible. Do not extrapolate.
2.External static pressure is the static pressure difference between the return duct and the supply duct plus the static
pressure caused by any FIOPs or accessories.
3.Tabular data accounts for pressure loss due to clean filters, unit casing, and wet coils. Factory options and
accessories may add static pressure losses. Selection software is available to help you select the best motor/drive
combination for your application.
4.The Fan Performance tables offer motor/drive recommendations. In cases when two motor/drive combinations
would work, recommend the lower horsepower option.
5.For information on the electrical properties of motors, please see the Electrical information section of this book.
6.For more information on the performance limits of motors, see the application data section of this book.
7.The EPACT (Energy Policy Act of 1992) regulates energy requirements for specific types of indoor fan motors.
Motors regulated by EPACT include any general purpose, T−frame (three−digit, 143 and larger), single−speed,
foot mounted, polyphase, squirrel cage induction motors of NEMA (National Electrical Manufacturers Association)
design A and B, manufactured for use in the United States. Ranging from 1 to 200 Hp, these continuous−duty
motors operate on 230 and 460 volt, 60 Hz power. If a motor does not fit into these specifications, the motor does
not have to be replaced by an EPACT compliant energy efficient motor. Variable speed motors are exempt from
EPACT compliance requirements. Therefore, the indoor fan motors for RGS036−180 units are exempt from these
requirements.

1. Unbalanced 3‐Phase Supply Voltage
Never operate a motor where a phase imbalance in supply
voltage is greater than 2%. Use the following formula to de­
termine the percentage of voltage imbalance.
Example: Supply voltage is 230‐3‐60
AB = 224 v
BC = 231 v
AC = 226 v
Average Voltage =
(224 + 231 + 226)

Determine maximum deviation from average voltage.
(AB) 227 – 224 = 3 v
(BC) 231 – 227 = 4 v
(AC) 227 – 226 = 1 v
Maximum deviation is 4 v.

General
SEQUENCE OF OPERATION
The sequence below describes the sequence of operation for an
electro−mechanical unit with and without a factory installed
Economizer IV or X. For information regarding a direct digital
controller, see the start−up, operations, and troubleshooting
manual for the applicable controller.
Units with no Economizer
Cooling —
When the thermostat calls for cooling, terminals G and Y1 are
energized. As a result, the indoor fan contactor (IFC) and the
compressor contactor (C1) are energized, causing the indoor fan
motor (IFM), compressor #1, and outdoor fan to start. If the unit
has 2 stages of cooling, the thermostat will additionally energize
Y2. The Y2 signal will energize compressor contactor #2 (C2),
causing compressor #2 to start. Regardless of the number of
stages, the outdoor fan motor runs continuously while unit is
cooling. When 2−speed motor with VFD system is utilized,
indoor fan motor runs at design CFM (full speed) during the
heating operation.
Cooling (2−speed indoor fan motor) —Per ASHRAE 90.1
standard section 6.4.3.10.b, during the first stage of cooling
operation the VFD will adjust the fan motor to provide 2/3rd of
the total cfm established for the unit. When a call for the second
stage of cooling is required, the VFD will allow the total cfm for
the unit established (100%).
Heating
NOTE: RGS units have either 1 or 2 stages of gas heat. When
2−speed indoor fan motor system is utilized, indoor fan motor
runs at design cfm (full speed) during the heating operation.
When the thermostat calls for heating, power is sent to W on the
Integrated Gas Controller (IGC) board. An LED (light−emitting
diode) on the IGC board turns on and remains on during normal
operation. A check is made to ensure that the rollout switch and
limit switch are closed and the induced−draft motor is running. If
the check was successful, the induced−draft motor is energized,
and when its speed is satisfactory, as proven by the “hall effect”
sensor, the ignition activation period begins. The burners will
ignite within 5 seconds. If the burners do not light, there is a
22−second delay before another 5−second attempt. This
sequence is repeated for 15 minutes or until the burners light. If,
after the 15 minutes, the burners still have not lit, heating is
84
This amount of phase imbalance is satisfactory as it is below the max­
imum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than 2%,
contact your local electric utility company immediately.
locked out. To reset the control, break 24−v power to the
thermostat.
When ignition occurs, the IGC board will continue to monitor the
condition of the rollout switch, the limit switches, the “hall effect”
sensor, as well as the flame sensor. 45 seconds after ignition
occurs, assuming the unit is controlled through a room
thermostat set for fan auto, the indoor−fan motor will energize
(and the outdoor−air dampers will open to their minimum
position). If, for some reason, the over−temperature limit opens
prior to the start of the indoor fan blower, the unit will shorten the
45−second delay to 5 seconds less than the time from initiation
of heat to when the limit tripped. Gas will not be interrupted to
the burners and heating will continue. Once the fan−on delay
has been modified, it will not change back to 45 seconds until
power is reset to the control.
On units with 2 stages of heat, when additional heat is required,
W2 closes and initiates power to the second stage of the main
gas valve. When the thermostat is satisfied, W1 and W2 open
and the gas valve closes, interrupting the flow of gas to the main
burners.
If the call for W1 lasted less than 1 minute, the heating cycle will
not terminate until 1 minute after W1 became active. If the unit is
controlled through a room thermostat set for fan auto, the
indoor−fan motor will continue to operate for an additional 45
seconds then stop. If the over−temperature limit opens after the
indoor motor is stopped, but within 10 minutes of W1 becoming
inactive, on the next cycle the time will be extended by 15
seconds. The maximum delay is 3 minutes. Once modified, the
fan off delay will not change back to 45 seconds unless power is
reset to the control. A LED indicator is provided on the IGC to
monitor operation.
Units with an Economizer
Cooling —
When free cooling is not available, the compressors will be
controlled by the zone thermostat. When free cooling is
available, the outdoor−air damper is modulated by the
economizer control to provide a 50F (10C) to 55F (13C)
mixed−air temperature into the zone. As the mixed air
temperature fluctuates above 55F (13C)or below 50F (10C)
dampers will be modulated (open or close) to bring the
mixed−air temperature back within control. If mechanical cooling
is utilized with free cooling, the outdoor−air damper will maintain
its current position at the time the compressor is started. If the

increase in cooling capacity causes the mixed−air temperature
to drop below 45F (7C), then the outdoor−air damper position
will be decreased to the minimum position. If the mixed−air
temperature continues to fall, the outdoor−air damper will close.
Control returns to normal once the mixed−air temperature rises
above 48F (9C). The power exhaust fans will be energized
and de−energized, if installed, as the outdoor−air damper opens
and closes.
If field−installed accessory CO2 sensors are connected to the
economizer control, a demand controlled ventilation strategy will
begin to operate. As the CO2 level in the zone increases above
the CO2 set point, the minimum position of the damper will be
increased proportionally. As the CO2 level decreases because
of the increase in fresh air, the outdoor−air damper will be
proportionally closed. For economizer operation, there must be a
thermostat call for the fan (G). If the unit is occupied and the fan
is on, the damper will operate at minimum position. Otherwise,
the damper will be closed.
When the economizer control is in the occupied mode and a call
for cooling exists (Y1 on the thermostat), the control will first
check for indoor fan operation. If the fan is not on, then cooling
will not be activated. If the fan is on, then the control will open
the economizer damper to the minimum position.
On the initial power to the economizer control, it will take the
damper up to 2 1/2 minutes before it begins to position itself.
After the initial power−up, further changes in damper position
can take up to 30 seconds to initiate. Damper movement from
full closed to full open (or vice versa) will take between 1 1/2 and
2 1/2 minutes. If free cooling can be used as determined from
the appropriate changeover command (switch, dry bulb,
enthalpy curve, differential dry bulb, or differential enthalpy),
then the control will modulate the dampers open to maintain the
mixed−air temperature set point at 50F (10C) to 55F (13C).
If there is a further demand for cooling (cooling second stage −
Y2 is energized), then the control will bring on compressor stage
1 to maintain the mixed−air temperature set point. The
economizer damper will be open at maximum position.
economizer operation is limited to a single compressor.
509 11 3510 00
2−Speed Note: When operating in ventilation mode only, the
indoor fan motor will automatically adjust to 2/3rd of the total cfm
established.
Heating
The sequence of operation for the heating is the same as an unit
with no economizer. The only difference is how the economizer
acts. The economizer will stay at the Economizer Minimum
Position while the evaporator fan is operating. The outdoor−air
damper is closed when the indoor fan is not operating.
Optional Hot Gas Reheat Dehumidification System
Units with the factory equipped Hot Gas Reheat option are
capable of providing multiple modes of improved
dehumidification as a variation of the normal cooling cycle. The
Hot Gas Reheat option includes additional valves in the liquid
line and discharge line of each refrigerant circuit, a small reheat
condenser coil downstream of the evaporator, and Motormaster
variable−speed control of some or all outdoor fans. Operation of
the revised refrigerant circuit for each mode is described below.
The Hot Gas Reheat system provides three sub−modes of
operation: Cool, Reheat1, and Reheat2.
Cool mode − provides a normal ratio of Sensible and Latent
Cooling effect from the evaporator coil.
Reheat1 − provides increased Latent Cooling while slightly
reducing the Sensible Cooling effect.
Reheat2 − provides normal Latent Cooling but with null or
minimum Sensible Cooling effect delivered to the space.
The Reheat1 and Reheat2 modes are available when the unit is
not in a Heating mode and when the Low Ambient Lockout
switch is closed.
The following diagrams depict piping for Single Stage cooling
units.
