SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can

be hazardous due to system pressure and electrical compo-

nents. Only trained and qualified service personnel should

install, repair, or service air-conditioning equipment.

Untrained personnel can pet-form basic maintenance func-

tions of cleaning coils and filters and replacing filters. All other

operations should be performed by trained service personnel.

When working on air-conditioning equipment, observe precau-

tions in the literature, tags and labels attached to the unit, and

other safety precautions that may apply.

Follow all safety codes. Wear safety glasses and work

gloves. Use quenching cloth for unbrazing operations. Have

fire extinguisher available for all brazing operations.

Before performing service or maintenance operations on

unit, turn off main power switch to unit and install lockout

tag. Ensure voltage listed on unit data pkite agrees with

electrical supply provided for the unit. Electrical shock

could cause personal injury.

INSTALLATION

Unit is shipped in the vegical configuration. To conveg to

hotizont_flconfiguration, remove side duct opening covers. Us-

ing the same screws, install covers on vertical duct openings

with the insulation-side down. Seals around duct openings

must be tight.

Step 1 -- Provide Unit Support

ROOF CURB -- Assemble and install the accessory roof curb

in accordance with instructions shipped with the curb. See

Fig. 1. Install insulation, cant strips, roofing felt, and counter

flashing as shown. Ductwork must be attached to curb. If

electric or control power will be routed through the basepan,

use the proper accessory kit listed in Fig. 1, available fi'om your

local distributor Attach the accessory thru-the-bottom service

connections to the basepan in accordance with the accessory

installation instructions. Connections must be installed before

the unit is set on the roof curb.

IMPORTANT: The gasketing of the unit to the roof curb is [

critical for a water-tight se_d. Install gasket supplied with I

the roof curb as shown in Fig. 1. hnproperly applied gasket

can also result in air leaks and poor unit performance.

The roof curb should be level. Unit leveling tolerances ate

shown in Fig. 2. This is necesstuy for the unit drain to function

properly. Refer to Accessory Roof Curb Installation Instruc-

tions for additional information as tequired.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Fig. 2 -- Unit Leveling Tolerances

SLAB MOUNT (Horizontal Units Only) -- Provide a level

concrete slab that extends a minimum of 6 in. beyond the unit

cabinet on all sides. Inst_dl a grovel apron in front of the

outdoor coil air inlet to prevent grass and foliage fi_)m obstruct-

ing airflow.

NOTE: Holizont_d units may be installed on a roof curb if

required.

ALTERNATE UNIT SUPPORT -- When the curb or

adapter cannot be used, support unit with sleeper rtfils using

unit curb or adapter support mea. If sleeper rails cannot be

used, support the long sides of the unit with a minimum of

3 equ_dly spaced 4-in. x 4-in. pads on each side.

Step 2 -- Field Fabricate Ductwork -- On verti-

c:d discharge units, secure _dlducts to the roof curb and building

structure. Do not connect dm m'ork to the unit. For horizontal

applications, tield-supplied flanges should be attached to

horizontal dischmge openings and all ductwork attached to the

flanges. Insulate and weatherproof all extern_fl ductwoN, joints,

and roof openings with counter flashing and mastic in accor-

dance with applicable codes.

Ducts passing through an unconditioned space must be

insulated and covered with a vapor bamel:

If a plenum return is used on a vertical unit, the return

should be ducted through the roof deck to comply with applica-

ble fire codes.

A minimum clearance is not required around ductwoN.

Cabinet return-air static pressure (a negative condition) should

not exceed 0.35 in. wg with economizel: or 0.45 in. wg without

economizel:

Step 3 -- Install Condensate Drain Line and

External Trap -- Condensate drain connections tire locat-

ed at the bottom and end of the unit. Unit discharge connec-

tions do not determine the use of di'ain connections;

either diain connection can be used in vertic_d or horizont_d

applications.

When using the standard end di'ain connection, make sure

the plug in the alternate bottom connection is tight before in-

stalling the unit.

To use the bottom drain connection for a roof curb inst_dla-

tion, relocate the factory-inst_dled plug from the bottom connec-

tion to the end connection. The center diain plug looks like a stm

connection, bnt can be removed with a I/z-in. socket diive exten-

sion. See Fig. 3. The piping for the condensate di_dn and extermfl

trap can be completed after the unit is in place.

All units must have an extern_d trap for condensate chain-

age. Install a trap at least 4-in. deep and protect against freeze-

up. If di'ain line is installed downstream from the extern_d trap,

pitch the line away from the unit at 1/4-in. per ft of run. Do not

use a pipe size smaller than the unit connection. See Fig. 4.

Step 4 -- Rig and Place Unit --Inspect the unit for

transportation &image. File any claim with the transpollation

agency. Keep the unit upright and do not diop it. Spreader bras

me not required if top crating is left on the unit. Rollers may be

used to move the unit across a roof. Level by using the unit

fi_lme as a reference. See Table 1 and Fig. 5 for additional

information. Operating weight is shown in Table 1 and Fig. 5.

Lifting holes are provided in the base rails as shown in

Fig. 5 and 6. Refer to rigging instructions on the unit.

POSITIONING -- Maintain clearance around and above the

unit to provide proper tdrflow and service access. See Fig. 6.

Position the unit on the roof curb so that the following clear-

traces me maintained: l/4-in, clearance between the roof curb

and base rails on each side and in front of the unit; 35/1(_-in.

clearance between the roof curb and the outdoor fan end of the

unit (see Fig. 1, section C-C).

Do not install the unit indoors. Do not locate the unit _fir

inlet near exhaust vents or other sources of contaminated all:

Although the unit is weatherproof, guard against water from

higher level runoff and overhangs.

After the unit is in position, remove the polyethylene ship-

ping wrapper and rigging skid.

Step 5 -- Make Electrical Connections

Unit cabinet must have an uninterrupted, unbroken electri-

cal ground to minimize the possibility of personal inju Uif

an electrical fault should occm_ This ground may consist of

electrical wire connected to unit ground lug in control com-

partment, or conduit approved for electrical ground when

installed in actor&race with NEC (National Electrical

Code) ANSI (American Nation_d Stand_uds Institute)/

NFPA (National Fire Protection Association) 70 latest yetu

and local electrical codes. Failure to follow this warning

could result in the installer being liable for personal inju U

of others.

FIELD POWER SUPPLY -- All units except 208/230-v

units are factory-wired for the voltage shown on the unit name-

plate. If the 208/230-v unit is to be connected to a 208-v power

supply, the transformer must be rewired by disconnecting the

black wire from the 230-v l/4-in, male spade terminal on the

tmnsforlner and connecting it to the 208-v l/4-in, m_de spade

terminal from the transformel:

Refer to the unit label diagrmn for additional information.

Pigttfils tue provided for field wire connections. Use factory-

supplied splices or a UL Underwriters' Laboratories) approved

copper/tduminum connectoc

When inst_dling units, provide a disconnect per the NEC.

All field wiring must comply with the NEC and local re-

quirements. In Canada, electrical connections must be made in

accor&mce with CSA (Canadian Stan&trds Association) C22.1

Canadian Electric_d Code Part One.

Inst_dl field wiring as follows:

1. Inst_dl conduit through the side panel openings. For units

without electric heat, inst_dl conduit between the discon-

nect and control box.

2. Inst_dl power lines to terminal connections as shown in

Fig. 7.

3. For units with electric heat, refer to Table 2 and Accessory

Installation Instructions.

During operation, voltage to compressor terminals must be

within range indicated on unit nameplate (see Tables 3A and

3B). On 3-phase units, voltages between phases must be bal-

anced within 2%, and the current within 10%. Use the formula

shown in Tables 3A and 3B, Note 2 on page 11 to determine

the percentage of voltage imbalance. Operation on improper

line voltage or excessive phase imbalance constitutes abuse

and may cause damage to electrical components. Such opera-

tion would invalidate any applicable Carrier wammty.

*Two heater packages required to provide kW indicated.

rUse CRSINGLEOO8AOO for units with an electrical convenience outlet.

NOTES:

1. The rated heater voltage is 240,480, and 575 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.

2. To determine heater kW at voltages other than those shown in table, use the following formula:

Heater kW new = Heater kW rated x (unit power distribution voltage/rated heater voltage) 2

As an example:

For a 16 kW heater rated at 240 v with a power distribution voltage of 215 v

kW new = 16 kW (218/240) 2

kW new = 12.8 kW (rating at 215 v)

*Heaters are field installed only.

tUsed to determine minimum disconnect size per NEC.

**Heater capacity (kW) is based on heater voltage of 208 v, 240 v, 480 v, and 575 v. If

power distribution voltage to unit varies from rated heater voltage, heater kW will vary

accordingl_z

ttFuse or HACR circuit breaker.

***Optional disconnect switch is unavailable.

NOTES:

1. In compliance with NED requirements for multimotor and combination load equipment

(refer to NED Articles 430 and 440), the overcurrent protective device for the unit shall

be fuse or HACR breaker.

2. 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 determine the percent of voltage imbalance.

% Voltage Imbalance

max voltage deviation from average voltage

=100x average voltage

Example: Supply voltage is 460-3-60.

AB = 452 v

AB C BC =464 v

(_ AC =455 v 452 + 464 + 455

Average Voltage = 3

1371

=457

Determine maximum deviation from average voltage.

(AB) 457 - 452 = 5 v

(BC) 464 - 457 = 7 v

(AC) 457 - 455 = 2 v

Maximum deviation is 7 v.

Determine percent of voltage imbalance.

% Voltage Imbalance = 100 x 45_

= 1.53%

This amount of phase imbalance is satisfactory as it is below the maximum allowable

2%.

IMPORTANT: If the supply voltage phase imbalance is more than 2°,/o,contact your local

I electric utility company immediately. I

FIELD CONTROL WIRING -- Install a CmTier-approved

accessory thennostat assembly according to the installation

instructions included with the accessory. Locate file thermostat

assembly on a solid wall in the conditioned space to sense aver-

age temperature in accordance with the thermostat installation

instructions.

NOTE: If using a Carrier electronic thermostat, set the thenno-

star configuration for "non-heat pump operation." This family

of products does not require an O tenninal to energize the

reversing valve.

Route the thermostat cable or equivalent single leads of

colored wire fi_m the subbase terminals to the low-voltage

connections on the unit (shown in Fig. 8A and 8B) as described

in Steps 1 through 4 below.

NOTE: For wire runs up to 50 It, use no. 18 AWG (American

Wire Gage) insulated wire (35 Cminimum). For 51 to 75 It,

use no. 16 AWG insulated wire (35 Cminimum). For over

75 It, use no. 14 AWG insulated wire (35 Cminimum). All

wire kuger than no. 18 AWG cannot be directly connected to

the thermostat and will require a junction box and splice at the

thermostat.

1. If the unit is mounted on the roof curb and the accessory

thin-the-curb service plate connection is used, route wire

through the connection plate.

2. Pass control wires through the hole provided on the unit

(see connection D in Connection Sizes table in Fig. 6).

3. Feed wire through the raceway built into the comer post to

the 24-v bmrier located on the left side of the control box.

See Fig. 9. The raceway provides the UL required cletu-

ance between the high-voltage and low-voltage wiring.

4. Connect the thermostat wires to the screw terminals of

the low-voltage connector (see Fig. 8A and 8B).

NOTE: If the unit is mounted on a roof curb and electrical

power will be mn up "thin-the-bottom," use accessory kit

number CRBTMPWR002A01. This kit, available from your

local distributol: ensmes a watertight seal. Refer to the acces-

sory installation instructions for information on power wiring.

an option. Refer to Table 5 for sensor usage.

Install the Supply Air Temperature (SAT) Sensor -- When

the unit is supplied with a factory-mounted PremierLink con-

trol, the supply-air temperature (SAT) sensor (33ZCSENSAT)

is factory-supplied and wired. The wiring is routed from the

PmmierLink control over the control box, through a grommet,

into the fan section, down along the back side of the fan, and

along the fan deck over to the 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 inst¢fllation. Re-position the sensor for installation.

Re-position the sensor in the flange of the supply-air opening

or in the supply air duct (as mquiled by local codes). Drill or

punch a l/2-in, hole in the flange or duct. Use two field-

supplied, self-drilling screws to secure the sensor probe in a

horizontal orientation.

NOTE: The sensor must be mounted in the dischmge airstmam

downstream of the cooling coil and any heating devices. Be

sure that the probe tip does not come in contact with any of the

Enthalpy Sensors and Control -- The enthalpy control

(HH57AC077) is supplied as a field-inst_flled accessory to be

used with the economizer damper control option. The outdoor

air enthalpy sensor is part of the enthalpy control. The separate

field-inst_dled accessory return aw enthalpy sensor

(HH57AC078) is required for differential enthalpy control.

NOTE: The enthalpy control must be set to the "D" setting for

differential enthalpy control to won properly.

The enthalpy control receives the indoor and return

enthalpy from the outdoor and return tfir enthalpy sensors and

provides a @ contact switch input to the PremierLinld TM

controllel: Ix)cate the controller in place of an existing econo-

mizer 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 preferred to the

return all: An open contact indicates that the economizer

should remain at minimum position.

ECONOMI$ER IV STANDARD SENSORS

Outdoor Air Temperature (OAT) Sensor -- The outdoor air

temperature sensor (HH57AC074) is a 10 to 20 mA device

used to measure the outdoor-air temperature. The outdoor-air

temperature is used to determine when the EconoMiSer IV can

be used for free cooling. The sensor is factory-inst_dled on the

EconoMiSer IV in the outdoor airstrealn. See Fig. 19. The op-

erating range of temperature measurement is 40 to 100 E

Supply Air Temperature (SAT) Sensor -- The supply air

temperature sensor is a 3 K thermistor located at the inlet of the

indoor fan. See Fig. 31. This sensor is factory inst_flled. The op-

erating range of temperature measurement is 0° to 158 E See

Table 6 for sensor temperature/resistance v_dues.

The temperature sensor looks like an eyelet terminal with

wires running to it. The sensor is located in the "crimp end"

and is seeded from moisture.

Outdoor Air Lockout Sensor -- The EconomiSer IV is

equipped with an alnbient temperature lockout switch located

in the outdoor air stream which is used to lockout the compres-

sors below a 42 F ambient temperature. See Fig. 19.

ECONOM[$ER IV CONTROL MODES

IMPORTANT: The 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.

Determine the EconoMiSer IV control mode before set up of

the control. Some modes of operation may require different sen-

sors. Refer to Ntble 7. The EconoMiSer IV is supplied from the

factory with a supply air temperature sensor and an outdoor tdr

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.

Outdoor DLy Bulb Changeover -- The standard controller is

shipped from the facto qconfigured for outdoor @ bulb

changeover control. The outdoor air and supply air temperature

sensors me included as standmd. For this control mode, the

outdoor temperature is compared to an adjustable set point

selected on the control. [f the outdoor-air temperature is above

the set point, the EconoMiSer 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 dampers will

be controlled to provide free cooling using outdoor all: When

in this mode, the LED next to the free cooling set point potenti-

ometer 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 sc_fle on the potentiometer is A,

B, C, and D. See Fig. 33 for the corresponding temperature

changeover values.

Differential Dry Bulb Control -- For differential dry bulb

control the standard outdoor dry bulb sensor is used in conjunc-

tion with an additional accessory dry bulb sensor (part number

CRTEMPSN002A00). Tile accessory sensor must be mounted

in the return _fil_tream. See Fig. 34. Wiring is provided in the

EconoMi$er [V wMng harness. See Fig. 26.

In this mode of operation, the outdoor-air temperatme is

compared to the return-tilt temperature and the lower tempera-

ture airsUeam is used for cooling. When using this mode of

changeover control, turn the enthalpy set point potenfiometer

fully clockwise to the D setting. See Fig. 32.

Outdoor Enthalpy Changeover -- For enthalpy control, ac-

cessory enthalpy sensor (part number HH57AC078) is le-

quiredi Replace the standiu'd outdoor dry bulb temperature sen-

sor with the accesso Uenthalpy sensor in the same mounting

location. See Fig. 19. When the outdoor air enthalpy rises

above the outdoor enth_dpy changeover set point, the outdoor-

air damper moves to its minimum position. Tile outdoor

enthalpy changeover set point is set with the outdoor enthalpy

set point potentiometer on the EconoMiSer IV controllel: 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 EconoMi$er IV controllel: See Fig. 19 and 36.

Differential Enthalpy Control -- For differential enthalpy

control, the EconoMiSer IV controller uses two enthalpy sen-

sors (HH57AC078 and CRENTDIF004A00), one in the out-

side air and one in the leturn air duct. The EconoMiSer [V

controller comptues file outdoor air enthalpy to the return air

enthalpy to determine EconoMi$er IV use. The controller

selects the lower enthalpy air (return or outdoor) for cooling.

For example, when file outdoor air has a lower enthalpy than

the return tfir. the EconoMiSer IV opens to bring in outdoor air

for free cooling.

Replace the standard outside air dUbulb temperature sen-

sor with file accessory enthalpy sensor in the same mounting

location. See Fig. 19. Mount the return air enthalpy sensor in

the return air duct. See Fig. 34. Wiring is provided in the

EconoMiSer IV wiring harness. See Fig. 26. The outdoor en-

thalpy changeover set point is set with the outdoor enthalpy set

point potentiometer on the EconoMi$er IV controllel: When

using this mode of changeover control, turn the enthalpy set-

point potentiometer fully clockwise to the D setting.

Indoor Air Ouality (IAO) Sensor Input -- The IAQ input

can be used for demand control ventilation control based on the

level of CO2 measured in the space or leturn air duct.

Mount the accesso UIAQ sensor according to manufacturer

specifications. The IAQ sensor should be wired to file AQ and

AQI terminals of the controllel: Adjust the DCV potentiome-

ters to correspond to file DCV voltage output of the indoor air

quality sensor at the user-determined set point. See Fig. 37.

If a separate field-supplied transformer is used to power the

IAQ sensor, the sensor must not be grounded or the

EconoMi$er IV control bo_ud will be &tmaged.

Exhaust Set Point Adjustment -- The exhaust set point will

determine when the exhaust fan runs based on dalnper position

(if accessory power exhaust is installed). The set point is modi-

fied 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 damp-

ers to open. This delay allows file damper to reach the appro-

priate position to avoid unnecessary fan overload.

Minimum Position Control -- There is a minimum damper

position potentiometer on the EconoMiSer [V controllel: See

Fig. 32. The minimum damper position maintains the mini-

mum airflow into the building during the occupied period.

When using demand ventilation, the minimum dalnper po-

sition represents the minimum ventilation position for VOC

(volatile organic compound) ventilation requirements. The

maximum demand ventilation position is used for fully occu-

pied ventilation.

When demand ventilation control is not being used, the

minimum position potentiometer should be used to set the oc-

cupied ventilation position. The maximum demand ventilation

position should be turned fully clockwise.

Adjust the minimum position potentiometer to allow the

minimum amount of outdoor aik as required by local codes, to

enter the building. Make minimum position adjustments with

at least 10 F temperature difference between the outdoor and

return-air temperatures.

To determine the minimum position setting, perform the

following procedure:

1. Calculate the appropriate mixed air temperature using the

following formula:

OA RA

(Tox 1---_7) +(TRx 1-]Ti-(]-)=TM

To = Outdoor-Air Temperature

OA = Percent of Outdoor Air

TR = Return-Air Temperature

RA = Percent of Return Air

TM = Mixed-Air Temperature

As an example, if local codes require 10% outdoor air

during occupied conditions, outdoor-air temperature is

60 Eand return-air temperature is 75 E

(60 x .10) + (75 x .90) = 73.5 F

2. Disconnect the supply air sensor from temfinals T and

TI.

3. Ensure that the factory-installed jumper is in place across

terminals P and PI. If remote damper positioning is being

used, make sure that the terminals are wired according to

Fig. 26 and that the minimum position potentiometer is

turned fully clockwise.

4. Connect 24 vac across terminals TR and TRI.

5. Carelully adjust the minimum position potentiometer

until the measured mixed-air temperature matches the

calculated value.

6. Reconnect the supply air sensor to termimds T and TI.

Remote control of the EconoMiSer IV damper is desirable

when requiring additional tempormy ventilation. If a

field-supplied remote potentiometer (Honeywell part number

$963B1128) is wired to the EconoMiSer IV controllek the

minimum position of the damper can be controlled from a re-

mote location.

To control the minimum damper position remotely, remove

the factory-installed jumper on the P and PI terminals on the

EconoMiSer IV controllel: Wire the field-supplied potentiome-

ter to the P and PI terminals on the EconoMiSer IV controller.

See Fig. 36.

Damper Movement -- Damper movement trom full open to

full closed (or vice versa) takes 2112minutes.

Thermostats -- The EconoMi$er IV control works with con-

ventional thermostats that have a YI (cool stage 1), Y2 (cool

stage 2), Wl (heat stage 1), W2 (heat stage 2), and G (fan). The

EconoMi$er IV control does not support space temperature

sensors. Connections are made at the thermostat terminal con-

nection board located in the main control box.

Occupancy Control -- The factoUdefault configuration for

the EconoMi$er IV control is occupied mode. Occupied status

is provided by the black jumper fiom terminal TR to terminal

N. When unoccupied mode is desired, inst_dl a field-supplied

timeclock function in place of the jumper between TR and N.

See Fig. 26. When the timeclock contacts are closed, the

EconoMi$er IV control will be in occupied mode. When the

timeclock contacts are open (removing the 24-v signal from

terminal N), the EconoMi$er IV will be in unoccupied mode.

Demand Controlled Ventilation (DCV) -- When using the

EconoMi$er IV for demand controlled ventilation, them are

some equipment selection criteria which should be considered.

When selecting the heat capacity and cool capacity of the

equipment, the maximum ventilation rote must be ev_duated for

design conditions. The maximum damper position must be cal-

culated to provide the desired fresh air

Typically the maximum ventilation rate will be about 5 to

10% more than the typical cfin required per person, using

norm_doutside air design criteria.

A proportional anticipato Ustrategy should be taken with

the following conditions: a zone with a large area, varied occu-

pancy, and equipment that cannot exceed the required ventila-

tion rate at design conditions. Exceeding the required ventila-

tion rate means the equipment can condition air at a maximum

ventilation rate that is greater than the required ventilation rate

for maximum occupancy. A proportional-anticipato Ustrategy

will cause the fresh air supplied to increase as the room CO2

level increases even though the CO2 set point has not been

machedi By the time the CO2 level roaches 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, fil.stdetermine the damper voltage out-

put for minimum or base ventilation. Base ventilation is the

ventilation required to remove contmninants during unoccu-

pied 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 there should be at least a

10 degree difference in outside and return-air temperatures.

OA RA

(To x 1--_) + (TR x 1--_) = TM

To = Outdoor-Air Temperature

OA = Percent of Outdoor Air

TR = Return-Air Temperature

RA = Percent of Return Air

TM = Mixed-Air Temperature

Once base ventilation has been determined, set the mini-

mum damper position potentiometer to the correct position.

The same equation can be used to determine the occupied or

maximum venfihttion rote to the building. For example, an out-

put of 3.6 volts to the actuator provides a base ventihttion rate

of 5% and an output of 6.7 volts provides the maximum venti-

lation rate of 20% (or base plus 15 cfm per person). Use Fig. 37

to determine the maximum setting of the CO2 sensoc For ex-

ample, a 1100 ppm set point relates to a 15 cfm per person de-

sign. Use the 1100 ppm curve on Fig. 37 to find the point when

the CO2 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 CO2 sensor should be 1800 ppm. The

EconoMiSer IV controller will output the 6.7 volts from the

CO2sensortotheactuatorwhentheCO2concentrationinthe

spaceisat1100ppm.TheDCVsetpointmaybeleftat2volts

sincethe CO2 sensor voltage will be ignored by the

EconoMiSer IV controller until it rises above the 3.6 volt set-

ting of the minimum position potentiometel:

Once the fully occupied dmnper position has been deter-

mined, set file maximum damper demand control ventilation

potentiometer to this position. Do not set to file maximum posi-

tion as fills can result in over-ventilation to the space and poten-

tial high-humidity levels.

Dehumidification of Fresh Air with DCV Control -- Infor-

mation from ASHRAE indicates that the largest humidity load

on any zone is the fresh air introduced. For some applications,

a device such as a 62AQ energy recovery unit is added to re-

duce the moisture content of the fiesh tdr being brought into the

building when the enthalpy is high. In most cases, the normal

heating and cooling processes are more than adequate to re-

move the humidity loads for most commercial applications.

If normal rooftop heating and cooling operation is not ade-

quate for the outdoor humidity level, an energy recovery unit

and/or a dehumidification option should be considered.

Step 7 -- Adjust Indoor-Fan Speed -- Adjust the

Table 9 shows indoor-fan motor data. Table 10 shows fan

rpm at motor pulley settings for standard and alternate motors.

Tables 1lA and 11B show static pressure for accessories. Refer

to Tables 12-27 to determine fan speed settings. Fan motor

pulleys are factory set for speed shown in Table 1.

To change fan speeds:

1. Shut offthe unit power supply and tag disconnect.

2. Ix_osen the belt by loosening the fan motor mounting

nuts. See Fig. 38 and 39.

3. Ix_osen the movable pulley flange setscrew (see Fig. 40).

4. Screw the movable flange tow_ud file fixed flange to

increase speed or away from file fixed flange to decrease

speed. Increasing the fan speed increases the load on the

motol: Do not exceed the maximum speed specified in

Table 1.

5. Set the movable flange at nearest keyway of the pulley

hub and tighten the setscrew. (See Table 1 for speed

change for each full turn of the pulley flange.)
