ROOF CURB -- Assemble and install accesso U roof curb in
accor&mce with instructions shipped with curb. See Fig. 2.
Install insulation, cant strips, roofing felt, and counter flashing
as shown. Ductwork must be attached to curb, not to unit.
If electric or control power is to be routed through rite basepan,
attach the accessory thru-the-bottom
service connections to the
basepan in accor&mce with the accessory installation instructions. Connection must be installed b@re unit is set on roof

CONSIDERATIONS

Installation and servicing ah-conditioning
equipment can be
hazardous due to system pressure and electrical components.
Only tlained and qualified service personnel should install,
repair, or service air-conditioning equipment.

Step 3 --

-- The unit's 3/4-in. condensate drain connections are
located at the bottom and side of the unit. Unit discharge
connections do not determine the use of &'ain connections;
either drain connection can be used with vertical or horizont;fl
applications.
When using the standard side drain connection, make sure
the red plug in the alternate bottom connection is tight before
inst;dling the unit.
To use the bottom drain connection for a roof curb installation, lelocate the factory-installed
red plug from the bottom
connection to file side connection. See Fig. 4. The piping for
the condensate drain and external trap can be completed after
the unit is in place. Tile center drain plug looks like a star
connection, howevek it can be removed with a l/2-in, socket
drive extension.

Step 2 --

Field Fabricate Ductwork -- Secure _fll
ducts to roof curb and building structure on vertical discharge
units. Do not connect dm_'ork
to unit. For horizontal applications, field-supplied flanges should be attached to horizontal
discharge openings and all ductwork should be attached to the
flanges. Insulate and weatherproof
all extern_d ductwork,
joints, and roof openings with counter flashing and mastic in
accor&mce with applicable codes.

All units must have an extern;d trap for condensate drainage. Install a trap at least 4 in. deep and protect against freezeup. If drain line is installed downsneam from the external trap,
pitch the line away from the unit at 1 in. per 10 fl of run. Do not
use a pipe size sm;dler than the unit connection (3/4-in.). See
Fig. 5.

PREMIERLINK
rM CONTROL
-- Tile PremierLink controllet is compatible
with Career Comfort Network®
(CCN)
devices. This control is designed to allow usel5 file access and
ability to change factory-defined
settings, thus expanding the
function of the stan&trd unit control board. CmTier's diagnostic
standard tier display tools such as Navigator TM or Scrolling
Marquee can be used with the PremierLink contmfler.

NOTE: The sensor must be mounted in the discharge airstream
downstream of file cooling coil and any heating devices. Be
sure the probe tip does not come in contact with any of the unit
or heat surfaces.
Outdoor Air Temperature (OAT) Sensor -- When the unit is
supplied with a factou-mounted PremierLink control, the
outdoor-air temperature sensor (OAT) is factou-supplied and
wimdi

The PremierLink contmfler (see Fig. 15A and 15B) requires
the use of a Canier electronic thermostat or a CCN connection
for time broadcast to initiate its intermfl fimeclock. This is
necessary for broadcast of time of day functions (occupied/
unoccupied). No sensors am supplied wifli the field-mounted
PremierLink control. The factory-installed
PmmierLink
control includes only file supply-air temperature (SAT) sensor and
the outdoor air temperature
((-)AT) sensor as standard. An
indoor air qutflity (CO2) sensor can be added as tin option.
Refer to Table 3 for sensor usage_ Refer to Fig. 16 for
PremierLink controller wiring. The PmmierLink control may
be mounted in the control panel or an area below the control

Install the Indoor Air Quality (CO2'_Sensor -- Mount the
optional indoor air quality (CO2) sensor according to manufacturer specifications.
A separate field-supplied transformer must be used to power the CO 2 sensol:
Wire the CO 2 sensor to the COM and IAQI terminals of J5
on the PremierLink controller Refer to the PremierLink [nstallation, Start-up, and Configuration Instructions for detailed
wiring and configuration information.
Enthalpy Sensors and Control -- The enthalpy control
(HH57AC077) is supplied as a field-installed accesso U to be
used with the economizer damper control option. The outdoor
air enthalpy sensor is part of the enthalpy control. The separate
field-installed
accessory
return
mr enthalpy
sensor
(HH57AC078) is required for differential enthalpy control.
NOTE: The enthalpy control must be set to the "D" setting for
diffemnfial enthalpy control to work properly.
The enthalpy control receives the indoor and return
enthalpy from the outdoor and return air enthalpy sensors and
provides a diy contact switch input to the PremierLink controllel: Locate the controller in place of an existing economizer
controller or near the actuatol: The mounting plate may not be
needed if existing bracket is used.
A closed contact indicates that outside air is prefened to the
return ail: An open contact indicates that the economizer
should remain at minimum position.

panel.
NOTE: PremierLink
controller versions 1.3 and later me
shipped in Sensor mode. If used with a thennostat,
the
PremierLink controller must be configured to Thermostat mode.
Install the Supply Air Temperature
(SAT) Sensor -- When
the unit is supplied with a factou-mounted
PremierLink control, the supply-air temperature (SAT) sensor (33ZCSENSAT)
is factou-supplied
and wired. The wiring is muted fl_)m the
PremierLink control over the control box, through a grommet,
into the fan section, down tflong the back side of the fan, and
along the fan deck over to file supply-air opening.
The SAT probe is wire-tied to the supply-air opening (on the
horizontal opening end) in its shipping position. Remove the
sensor for installation. Re-position the sensor in the flange of
the supply-air opening or in the supply air duct (as required by
local codes). Drill or punch a I/_-in. hole in the flange or duct.
Use two field-supplied, self-diilling screws to secure the sensor
probe in a horizontal orientation.

temperature airstream is used for cooling. When using this
mode of changeover control, turn the enthalpy set point potentiometer fully clockwise to the D setting. See Fig. 32.

IMPORTANT:
Tile optional
EconoMiSer2
does not
include a controllel: The EconoMiSer2 is operated by a 4 to
20 mA signal from an existing field-supplied
controller
(such as PremierLink TM control). See Fig. 27 for wiring
information.

Outdoor Enthalpy Changeover
-- For enthalpy control, accessory enthalpy sensor (part number HH57AC078)
is required. Replace the stan&_rd outdoor dry bulb temperature sensor with the accessory enthalpy sensor in the same mounting
location. See Fig. 19. When the outdoor air enthalpy rises
above the outdoor enthalpy changeover set point, the outdoortdr dmnper moves to its minimum position. The outdoor
enthalpy changeover set point is set with the outdoor enthalpy
set point potentiometer on the EconoMiSer IV controllec The
set points are A, B, C, and D. See Fig. 35. The factory-installed
620-ohm jumper must be in place across terminals SR and SR+
on the EconoMiSer IV controllel: See Fig. 19 and 36.

Determine tile EconoMiSer IV control mode befole set up of
the control. Some modes of operation may requile diffelent sensors. Refer to Ntble 5. The EconoMiSer IV is supplied from the
factory with a supply air temperature sensor and an outdoor air
temperature
sensol: This allows
for operation
of the
EconoMiSer IV with outdoor air dry bulb changeover control.
Additional accessories c_m be added to allow for different types
of changeover control and operation of the EconoMiSer IV and
unit.

Differential Enthalpy Control
-- For differential
enthalpy
control, the EconoMiSer IV controller uses two enthalpy sensors (HH57AC078
and CRENTDIF004A00),
one in the outside air and one in the return air duct. The EconoMiSer IV
controller compares the outdoor air enthalpy to the return air
enth_dpy to determine EconoMiSer
IV use. The controller
selects the lower enthalpy air (return or outdoor) for cooling.
For example, when the outdoor air has a lower enth_dpy than
the return ail, the EconoMiSer IV opens to bring in outdoor air
for free cooling.

Outdoor Dry Bulb Changeover
-- The stan&_rd controller is
shipped from the factory configured
for outdoor dry bulb
changeover control. The outdoor air and supply air temperature
sensors are included as stan&_rd. For this control mode, the
outdoor temperature is compmed to an adjustable set point
selected on the control. If the outdoor-air temperature is above
the set point, the EconoMi$er
IV will adjust the outdoor-air
dampers to minimum position. If the outdoor-air temperature is
below the set point, the position of the outdoor-air dampel.s will
be controlled to provide free cooling using outdoor all: When
in this mode, the LED next to the free cooling set point potentiometer will be on. The changeover
temperature set point is
controlled by the free cooling set point potentiometer
located
on the control. See Fig. 32. The scale on the potentiometer is A,
B, C, and D. See Fig. 33 for the conesponding

Exhaust Set Point Adjustment
-- The exhaust set point will
determine when the exhaust fan runs based on &_mper position
(if accessory power exhaust is installed). The set point is modified with the Exhaust Fan Set Point (EXH SET) potentiometer
See Fig. 32. The set point represents the damper position above
which the exhaust fans will be turned on. When there is a call
for exhaust, the EconoMiSer IV controller provides a 45 _+15
second delay before exhaust fan activation to allow the dampers to open. This delay allows the &tmper to reach the appropriate position to avoid unnecessary fan overload.

Damper Movement
-- Damper movement from full open to
lull closed (or vice versa) takes 21/2 minutes.
Thermostats
-- The EconoMiSer IV control works with conventional thermostats that have a YI (cool stage 1), Y2 (cool
stage 2), WI (heat stage 1), W2 (heat stage 2), and G (fan). The
EconoMi$er
[V control does not support space temperature
sensors. Connections me made at the themlostat terminal connection board located in the main control box.
Occupancy Control -- The factory default configuration for
the EconoMiSer IV control is occupied mode. Occupied status
is provided by the black jumper from terminal TR to terminal
N. When unoccupied mode is desired, install a field-supplied
timeclock lunction in place of the jumper between TR and N.
See Fig. 26. When the timeclock contacts are closed, the
EconoMiSer IV control will be in occupied mode. When the
timeclock contacts are open (removing the 24-v signal from
terminal N), the EconoMiSer IV will be in unoccupied mode.

Minimum Position Control -- There is a minimum &tmper
position potentiometer on the EconoMiSer IV controllel: See
Fig. 32. The minimum dmnper position maintains the minimum airflow into the building during the occupied period.
When using demand ventilation, the minimum damper position represents the minimum ventilation position for VOC
(volatile organic compound)
ventilation requirements.
The
maximum demand ventilation position is used for fully occupied ventilation.

since the CO 2 sensor voltage will be ignored by the
EconoMiSer IV controller until it rises above the 3.6 volt setting of the minimum position potentiometel:

A proportional anticipatory strategy should be taken with
the following conditions: a zone with a large area, varied occupancy, and equipment that cannot exceed the required ventilation rate at design conditions. Exceeding the required ventilation rate means the equipment can condition air at a maximum
ventilation rate that is greater than the lequired ventilation rate
for maximum occupancy. A proportional-anticipatory
strategy
will cause tile fresh air supplied to increase as the room CO2
level increases even though the CO 2 set point has not been
reached. By the time the CO 2 level reaches the set point, the
damper will be at maximum ventilation and should maintain
the set point.
In order to have the CO2 sensor control the economizer
damper in this manner, first detemfine file damper voltage output for minimum or base ventilation. Base ventilation is the
ventilation required to remove contaminants
during unoccupied periods. The following equation may be used to determine
the percent of outside-air entering the building for a given
damper position. For best results thele should be at least a
10 degree difference in outside and leturn-air temperatures.

Once the fully occupied dmnper position has been determined, set ti3e maximum dalnper demand control ventilation
potentiometer to this position. Do not set to the maximum position as this can result in over-ventilation to the space and potential high-humidity levels.

Once base ventilation has been detemfined, set the minimum dmnper position potentiometer to the correct position.
The same equation can be used to determine the occupied or
maximum ventilation rate to the building. For example, an output of 3.6 volts to the actuator provides a base ventilation rate
of 5% and an output of 6.7 volts provides the maximum ventihttion rate of 20% (or base plus 15 cfln per person). Use Fig. 37
to determine the maximum setting of the CO 2 sensor For example, a 1100 ppm set point relates to a 15 cfln per person design. Use the 1100 ppm curve on Fig. 37 to find the point when
the CO 2 sensor output will be 6.7 volts. Line up the point on the
graph with the left side of the chart to determine that the range
configuration for the CO 2 sensor should be 1800 ppm. The
EconoMiSer IV controller will output the 6.7 volts from the
CO 2 sensor to the actuator when the CO 2 concentration in the

GENERAL FAN PERFORMANCE

NOTES

1. Values include losses for filters, unit casing, and wet coils.
2. Extensive motor and electrical testing on these units ensures that the full
range of the motor can be utilized with confidence. Using fan motors up to
the wattage ratings shown will not result in nuisance tripping or premature
motor failure. Unit warranty will not be affected. For additional information
on motor performance, refer to Table 8 on page 32.
3. Use of a field-supplied motor may affect wire sizing. Contact your Carrier
representative for details.
4. Interpolation is permissible. Do not extrapolate.

START-UP

Unit Preparationstalled in accordance
ble codes.

F;filure to observe the following warnings could result in
serious personal injuu:
1. Follow recognized safety practices and wear protective
goggles when checking or servicing refrigerant system.
2. Do not operate compressor or provide any electric
power to unit unless compressor terminal cover is in
place and secured.
3. Do not remove compressor terminal cover until all
electrical sources are disconnected.
4.

Return-Air Filters-

Make sure correct filters ale installed in unit (see Tables IA and IB). Do not operate unit
without return-air filters.

High

Flow Refrigerant
Valves -- Two high flow
valves are located on the hot gas tube coming out of the
compressor and the suction tube going into the compressol:
L;uge black plastic caps identify these valves with O-rings
inside screwing the cap and onto a brass body. No field access
to these wdves is available at this time. Ensure the plastic caps
remain on the valves and are tight or the possibility of refrigerant leakage could occm:

Compressor

Rotation-- On 50TFF,
TM007 scroll
compressor units, it is important to be certain compressor is
rotating in the proper direction. To determine whether or not
compressor is rotating in the proper direction:
1. Connect service gages to suction and discharge pressure
fittings.
2. Energize the compressol:
3. The suction pressure should diop and the discharge
pressure should rise, as is normal on any start-up.

inspections:

Inspect for shipping and handling damages
such
as broken lines, loose parts, or disconnected
wires.
Inspect for oil at all refrigerant tubing connections
and on unit base. Detecting oil generally indicates
a refrigerant
leak. Leak-test all refrigerant tubing
connections
using electronic
leak detector, halide
torch, or liquid-soap solution.
Inspect all field-wiring
and factory-wiring
connections. Be sure that connections
are completed
and tight. Ensure no electrical wiring is in contact
with refrigerant tubing or sharp edges.
Inspect coil fins. If damaged during shipping and
handling, carefully straighten fins with a fin comb.

If the suction pressure does not diop and the discharge
pressure does not rise to norlnal levels:
1. Note that the evaporator fan is probably _dso rotating
the wrong direction.
2. Turn off power to the unit. Install lock-out tag.
3. Reverse any two of the unit power leads.
4. Reapply power to the unit.

When fiee cooling is available the PremierLiuk control will
control the compressors and economizer to provide a supply;fir temperature determined to meet the YI and Y2 calls from
the thermostat using the following thlee routines. The three
control routines are based on OAT.

HEATING, UNITS WITHOUT ECONOMIZER
-- Upon a
request for heating from the space therlnostat, terminal WI will
be energized with 24 v. The IFC and heater contactor (HCI)
are energized.
COOLING, UNITS WITH ECONOMISER
IV -- When free
cooling is not available, the complessors will be controlled by
the zone thermostat.
When flee cooling is available, the
outdoor-air
dmnper is modulated
by the EconoMi$er
IV
control to provide a 50 to 55 F supply-air temperatme into the
zone. As the supply-air temperatme fluctuates above 55 or below 50 E the &_mpers will be modulated (open or close) to
bring the supply-air tempemtme back within the set point limits.

The 3 routines ale based on OAT where:

•

Integrated EconoMi$er IV operation on single-stage units requires a 2-stage thennostat (YI and Y2).
For EconoMi$er
IV operation, there must be a therlnostat
call for the fan (G). This will move the damper to its minimum
position during the occupied mode.

•

If the increase in cooling capacity causes the supply-air temperature to drop below 45 E then the outdoor-air cklmper position will be lully closed. If the supply-air temperature continues to fall, the outdoor-air dmnper will close. Control returns to
normal once the supply-air temperature rises above 48 E

•

•

•
•
•

If optional power exhaust is installed, as the outdoor-air
damper opens and closes, the power exhaust fans will be energized and deenergized.

•

If field-installed accesso U CO 2 sensors are connected to the
EconoMiSer IV control, a demand controlled ventilation strategy will begin to operate. As the CO,_ level in the zone increases
above the CO2 set point, the minimum position of the &_mper
will be increased proportionally. As the CO 2 level decreases
because of the inclease in fresh all: the outdoor-air damper will
be proportionally closed. Dmnper position will follow the higher demand condition from DCV mode or free cooling mode.

Damper movement from full closed to lull open (or vice

If optional power exhaust is installed, as the outdoor-air
damper opens and closes, the power exhaust fans will be energized and deenergized.
If field-installed accessory CO 2 sensors ;ue connected to the
PremierLink
control, a PlD-controlled
demand ventilation
strategy will begin to operate. As the CO2 level in the zone
increases above the CO_ set point, the minimum position of the
cklmper will be increased proportionally.
As the CO 2 level
decreases because of the increase in fresh ;fir, the outdoor-air
&_mper will be proportionally closed.

If fiee cooling can be used as determined fiom the appropriate changeover command (switch, d U bulb, enthalpy curve,
diffelential d U bulb, or differential enthalpy), a call for cooling
(YI closes at the thermostat) will cause the control to modulate
the &impels open to maintain the supply air temperature set
point at 50 to 55 E

COOLING.
UNITS WITH ECONOMI$ER2,
PREMIERLINK CONTROL
AND A ROOM SENSOR -- When free
cooling is not available, the compressors will be controlled by
the PremierLink controller using a PID Error reduction c_dculation as indicated by Fig 40.
The PremierLink controller will use the following information to deterraine if free cooling is available:
• Indoor fan has been on for at least 30 seconds.
• The SPT. SAT. and OAT inputs must have valid readings.
• OAT must be less than 75 tv.
• OAT must be less than SPT.
• Enthalpy
must be LOW (may be jumpered
if and
enthalpy sensor is not available).
• Economizer
position is NOT forced.
When free cooling is available, the outdoor-air damper is
positioned through the use of a Proportional
Integral (PID)
control process to provide a calculated supply-air temperature
into the zone. The supply air will maintain the space temperature between the heating and cooling set points as indicated in
Fig. 41.
The PremierLink controller will integrate the compressoLs
stages with the economizer based on similar logic as the three
routines listed in the previous section. The SASP will float up
and down based on the error reduction calculations that compare space temperature and space set point.
When outside-air temperature conditions require the economizer to close for a compressor stage-up sequence, the economizer control integrator is reset to zero after the stage-up sequence is completed. This prevents the supply-air temperature
from diopping too quickly and creating a freeze condition that
would make the compressor turn off prematurely.
The high space set point is used for DX (direct expansion)
cooling control, while the economizer space set point is a
c_dculated value between the heating and cooling set points.
The economizer set point will always be at least one degree
below the cooling set point, allowing for a smooth transition
from mechanical
cooling with economizer
assist, back to
economizer
cooling as the cooling set point is achieved.
The compressors
may be used for initial cooling then the
PremierLink controller will modulate the economizer using an
error reduction calculation
to hold the space temperature
between the heating and cooling set points. See Fig. 41.
The controller uses the following conditions to determine
economizer cooling:
• Enthalpy is Low
• SAT reading is available
• OAT reading is available
• SPT reading is available
• OAT < SPT
• Economizer
Position is NOT forced

If field-installed accessory CO 2 sensors gue connected to
the PremierLink TM control, a PID-controlled demand 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 flesh aik the outdoor-air
damper will be proportionally closed.
HEATING UNIT WITH ECONOMI$ER2, PREMIERLINK
CONTROL AND A ROOM SENSOR -- Eve U 40 seconds
the controller will calculate the required heat stages (maximum
of 3) to maintain supply-air temperature (SAT) if the following
qualifying conditions am met:
• Indoor fan has been on for at least 30 seconds.
• COOL mode is not active.
• OCCUPIED, TEMP.COMPENSATED START or HEAT
mode is active.
• SAT reading is available.
• Fire shutdown mode is not active.
If all of the above conditions gue met, the number of heat
stages is c_dculated; otherwise the required number of heat
stages will be set to 0.
If the PremierLink controller determines that heat stages am
required, the economizer damper will be moved to minimum
position if occupied and closed if unoccupied.
Staging should be as follows:
If Heating PID STAGES=2
• HEAT STAGES=I (50% capacity) will energize HSI
• HEAT STAGES=2 (100% capacity) will energize HS2
If Heating PID STAGES=3 and AUXOUT = HS3
• HEAT STAGES=I (33% capacity) will energize HSI
• HEAT STAGES=2 (66% capacity) will energize HS2
• HEAT STAGES=3 (100% capacity) will energize HS3
