SAFETY CONSIDERATIONS

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

Untrained personnel can perform basic maintenance functions 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 precautions 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 extinguishers available for all brazing operations.

CAUTION: Ensure voltage listed on unit data plate

agrees with electrical supply provided for the unit.

WARNING: Disconnect gas piping from unit when leak testing at pressure greater than 1/2 psig. Pressures greater tha n resulting in hazardous condition. If gas valve is ever subjected to pressure greater than replaced before use. When pressure testing fieldsupplied gas piping at pressures of unit connected to such piping must be isolated by manually closing the gas valve(s).

WARNING: Before performing service or maintenance operations on unit, turn off main power switch to unit and install lockout tag. Electrical shock could cause personal injury.

Unit is shipped in the vertical discharge configuration. To convert to horizontal configuration, remove screws from side duct opening covers and remove covers. Using the same screws, install covers on vertical duct openings with the insulation side down. Seals around duct openings must be tight. See Fig. 2.

Confirm before installation of unit that voltage, amperage and circuit protection requirements listed on unit data plate agree with power supply provided.

I. STEP 1 — PROVIDE UNIT SUPPORT

A. Roof Curb

Assemble and install access ory roof curb in accorda nce with instructions shipped with curb. See Fig. 3. Install insulation, cant strips, roofi ng fe lt, and counter flashing as shown. Duct- work must be attached to curb. If gas or electr ical co nnec tion s are to be routed through the curb, attach the access ory thruthe-curb service connectio n plate to the roof curb in accordance with the accessory installation instructions. Connections must be installed before unit is set on roof curb.

IMPORTANT: The gasketing of the unit to the roof curb is critical for a watertight seal. Install gasket supplied with the roof curb as shown in Fig. 3. Improperly applied gasket can also result in air or water leaks and poor unit performance.

Curb should be level. Unit leveling tolerances are shown in Fig. 4. This is necessary for unit drain to function properly. Refer to Accessory Roof Curb Installation Instructions for additional information as required.

If gas or electrical connections are to be routed through the bottom of the unit, attach accessory thru-the-bottom service connections to the basepan in accordance with the accessory installation instructions.

B. Alternate Unit Support

When the curb or adapter cannot be used, su pport unit with sleepers using un it curb or adapter supp ort area. If sleeper s cannot be used, support long sides of unit with a minimum of three 4-in. x 4-in. pads, two at the corners and one at the unit’s center of gravity. If more than 3 pads are used, equally space them along the side.

C. Slab Mount (Horizontal Units Only)

Provide a level concrete slab tha t extends a min imum of 6 in. beyond unit cabinet. Ins tall a 6-in. g ravel apron in f ront of condenser coil air inlet to prevent grass and foliage from obstructing airflow.

NOTE: Horizontal units may be installed on a roof curb if required.

II. STEP 2 — FIELD FABRICATE DUCTWORK

Secure all ducts to roof curb and building s tructure on verti cal units. Do not connect ductwork to unit. For horizontal applications, field-supplied flanges should be attached to horizontal discharge openings and all ductwork secured to the flanges. Insulate and weatherproof all external ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes.

Ducts passing through a n unc ondit i one d spa ce must be insulated and covered with a vapor barrier.

If a plenum return is used on a vertical unit, the return should be ducted through the roof deck to comply with applicable fire codes.

A minimum clearance is not required around ductwork. Cabinet return-air static shall not exceed –.30 in. wg with EconoMi$er+ or .45 in. wg without economizer.

These units are designed for a minimum heating operation continuous return-air te mperature of 50 F (dry bulb), o r an intermittent operation down to 45 F (dry bulb), such as when used with a night set-back thermostat.

To operate at lower return air temperatures, a field-supplied outdoor-air temperature control must be used to initiate both stages of heat when the temperature is below 45 F. Indoor

comfort may be compromised wh en these lo wer ai r temperatures are used with insufficient heating temperature ri se.

III. STEP 3 — INSTALL EXTERNAL TRAP FOR CONDENSATE DRAIN

The unit’s

/4-in. condensate drain connections ar e located on the bottom and side of the unit. Unit discharge connections do not determine the use of drain connections; either drain connection can be used with vertical or horizontal applications.

When using the standard side drain connection, make sure the plug (Red) in the alternate bottom connection is tight before installing the unit.

To use the bottom drain connection for a roof curb installation, relocate the factory-installed plug (Red) from the bottom connection to the side connection. See Fig. 5A. The piping for the condensate drain and external trap can be completed after the unit is in place.

All units must have an external trap for condensate drainage. Install a trap a minimum of 4-in. deep and protect against freeze-up. If drain line is installed downstream from the external trap, pitch the line away from the unit at 1 in. per 10 ft of run. Do not use a pipe size smaller than the unit connection (

/4 in.). See Fig. 5B .

The center drain plug looks lik e a star conne ctio n, however it can be removed with a

/2 in. socket drive extension.

IV. STEP 4 — RIG AND PLACE UNIT

Inspect unit for transportation damage. File any claim with transportation agency. Keep unit upright and do not drop. Spreader bars are not required if top crating is left on unit. Rollers may be used to move unit across a roof. Level by using unit frame as a reference. See Tables 1A and 1B and Fig. 6 for additional inf ormat ion. Op era ting we ight is s hown in Table 1 and Fig. 6.

Lifting holes are provided in base rails as shown in Fig. 1 and 6. Refer to rigging instructions on unit.

CAUTION: Al l panels must be in place wh en rig-

ging and lifting.

V. STEP 5 — INSTALL FLUE HOOD

Flue hood is shipped screwed to the burner compartment access panel. Remove from shipping location and, using screws provided, install flue hood and screen in location shown in Fig. 7.

VI. STEP 6 — INSTALL GAS PIPING

Unit is equipp ed for use with type of gas shown on nameplate. Refer to local building codes, or in the absence of local codes, to ANSI Z223.1-latest year and addendum Z223.1Alatest year entitled National Fuel Gas Code. In Canada, installation must be in accordance with the CAN1.B149.1 and CAN1.B149.2 installation codes for gas burning appliances when installing gas piping.

For natural gas applications, gas pressure at unit gas connection must not be less than 4.0 in. wg (5.0 in. wg in high heat units) or greater than 13.0 in. wg while unit is operating. For liquid propane applications, the pressure must not be less than 5.0 in. wg or greater than 13.0 in. wg at the unit connection.

Size gas supply piping for 0.5 i n. wg ma ximum pre ssure drop . Do not use supply pip e smaller than unit gas connection.

CAUTION: When installing gas piping to gas valve inlet, use properly sized back-up wrench on inlet flange flats to prevent valve damage.

Support gas piping as shown in the table in Fig. 8. For exam-

ple, a

/4-in. gas pipe must have one field-fabricated support

beam every 8 ft. See Fig. 8 for typical pipe guide and locations of external

manual gas shutoff valve. NOTE: If field-installed thru-the-bottom connections are

used, refer to the accessory installation instructions for power wiring and gas connections. Refer to Fig. 1A and 1B for drilling holes in basepan.

VII. STEP 7 — MAKE ELECTRICAL CONNECTIONS

WARNING: Unit cabinet must have an uninter-

rupted, unbroken electrical ground to minimize the possibility of personal injury if an electrical fault should occur. This ground may consist of electric al wir e connected to unit ground lug in control compartment, or conduit approved for electrical ground when installed in accordance with NEC (National Electrical Code), ANSI/NFPA (National Fire Protection Association), latest edition, and local electrical codes. Do not use gas piping as an electrical ground. Failure to follow this warning could result in the installer being liable for personal injury of other s.

A. Field Power Supply

All units except 208/230-v units are factory wired for the voltage shown on the na meplate. If the 208/230-v u nit is to be connected to a 208-v power supply, the transformer must

be rewired by moving the black wire from the 230- v

/4-in. male spade terminal on the transformer and connecting it to the 208-v

/4-in. male spade terminal from the transformer.

Refer to unit label diagram for additional information. Pigtails are provided for field service.

When installing units, provide a disconnect per NEC. Use copper conductors only when splice connectors are used.

All field wiring must comply with NEC and local requirements. In Canada, electrical connections must be in accordance with CSA (Canadian Standards Association) C22.1 Canadian Electrical Code Part One.

Fig.8—GasPipingGuide(With Accessory

Thru-the-Curb Service Connections)

Install conduit through side panel openings indicated in Fig. 1A and 1B. Route power lines through connector to terminal connections as shown in Fig. 9.

On 3-phase units, voltages between ph ase s must be balanced within 2% and the current within 10%. Use the formula shown in Tables 2A and 2B, Note 2 to determine the percentage of voltage im balance. Operation on improper line voltage or excessive phase imbalance constitutes abuse and may cause damage to electrical components. Such operation would invalidate any applicable Bryant warranty.

NOTE: If field-installed thru-the-bottom connections are used, refer to the accessory installation instructions for power wiring and gas connectio ns. Refer to Fig. 1A and 1B for drilling holes in basepan.

B. Field Control Wiring

Install a Bryant-approved accessory thermostat assembly according to installation instructions included with the accessory. Locate thermostat assembly on a solid wall in the conditioned space to sense average temperature in accordance with thermostat installation instructions.

NOTE: For wire runs up to 50 ft, use no. 18 AWG (American Wire Gage) insulated wire (35 C minimum). For 50 to 75 ft, use no. 16 AWG insulated wire (35 C minimum). For over 75 ft, use no. 14 AWG insulated wire (35 C minimum). All wire larger than n o. 18 AWG cannot be dir ectly con nect ed to the thermos tat and wi ll req uire a j unction box and s plice a t the thermostat.

NOTES:

1. In compliance with NEC requirements for multimotor and combination load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker. Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply voltage is greater than 2%.

of voltage imbalance. % Voltage Imbalance

= 100 x

Example: Supply voltage is 460-3-60.

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

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%, contact your local electric utility company immediately.

Use the following formula to determine the percent

max voltage deviation from average voltage

AB = 452 v BC = 464 v AC = 455 v

average voltage

Average Voltage =

457

=1.53%

452 + 464 + 455

1371

= 457

NOTE: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Must be in accordance with NEC or local codes.

Check MCA and MOCP when power exhaust is powered through the unit. Determine the new MCA including the power exhaust using the following formula:

MCA New = MCA unit only + MCA of Power Exhaust For example, using a 580FPV090 unit with MCA = 40.1 and MOCP

= 45, with CRPWREXH030A00 power exhaust. MCA New = 40.1 amps + 1.6 amps = 41.7 amps If the new MCA does not exceed the published MOCP, then MOCP

would not change. The MOCP in this example is 45 amps and the MCA New is below 45; therefore the MOCP is acceptable. If “MCA New” is larger than the published MOCP, raise the MOCP to the next larger size. For separate power, the MOCP for the power exhaust will be 15 amps per NEC.

C. EconoMi$er+ Control Mode

Determine the EconoMi$er+ control mode before installing sensors and accessories. Different sensors are required for different control modes, and a number of accessories are available. Refer to Tables 3 and 4.

Outdoor Dry Bulb Changeover The standard control mode for the EconoMi$er+ is Outdoor

Dry Bulb Changeover. The outdoor air an d supply air temperature sensors are also included as standard. EconoMi$er+ control is based on the outdoor temperature relative to a set point in the software. If the outdoor-air temperature is above the set point then the EconoMi$er should be in minimum position. If the outdoor-air temperature is below the set point, the position should be controlled to maintain the l eav ing a ir t emper ature set po in t. The s et po int range is 45 to 70 F.

Differential D r y Bulb Changeover The control supports differential dry bulb changeover con-

trol. This requires an accessory return air temperature sensor CRTEMPSN001A00 installed in the return airstream. Refer to the Start-up section for details on how to configure and enable the control mode. The user can check the operation of the s ensor using the Read function.

Outdoor Air Enthalpy Changeover The control support s ou tdoor air e nthal py cha ngeo ver con trol.

This mode requires a factory-supplied outdoor air temperature sensor (OAT) and an accessory outdoor air humidity sensor (ORH) (part no. CRHUMDSN001B00). Refer to the Start-Up section fo r details on how to con figure and enable th e control mode. The user ca n check the operation of the sensors using the Read function.

Differential Ent halpy Changeover The control supports differential enthalpy changeover con-

trol. This requires the factory-supplied outdoor air temperature sensor, an accessory outdoor air humidity sensor, an accessory return air temperature sensor, and an accessory indoor air humidit y sensor. Refer to the Start-Up section fo r details on how to configure and enable the control mode. The user can check the o peration of the sens ors using the Read function.

D. Damper Movement

When the EconoMi$e r+ board receives initia l power, it will take the damper up to 2

/2 minutes before it begins to position itself. After the initial positioning, subsequent changes to damper position will take up to 30 seconds to initiate. Damper movement from full open to full closed (or vice versa) takes 2

/2 minutes.

If the damper is in the process of changing positions (for example it is trying to open to 100%) and the fan signal is turned off, the damper will con tinue to its 100% open position before closing.

NOTE: Occupied minimum position can not be set lower than +1% higher than the value of IAQ minimum ec onomizer position. Refer to the setup examples on page 56.

E. EconoMi$er+ Controller Wiring

The EconoMi$er+ is sup plied fr om the factor y with a suppl y air temperature sensor and an outside air temperature sensor. This allows for operation of the EconoMi$er+ with outdoor air dry bulb changeover control. Additional accessories can be added to allow for different types of change over control and operation of the EconoMi$er+ and unit.

F. T hermostats

The EconoMi$er+ control works with conventional thermostats that have a Y1 (cool stage 1), Y2 (cool stage 2), W1 (heat stage 1), W2 (heat stage 2) , and G (fan). The EconoMi$er+ control does not support sensor thermostats l ike the T56 and T57. Connections are made at the thermos tat terminal connection board located in the main control box.

The user can read the value of the sensor using the Read mode, described in the EconoMi$er+ Controller section.

Mount the return air temp erature sens or on the Eco noMi$er+, through pre-punched holes. See F ig . 2 7.

The return air temperature (RAT) sensor is provided with a 2-wire, 42-in. long wiring harness with a 2-pin connector. The plug is installed on pins 5 and 6 on J3 of the EconoMi$er+ controller. The pins are labeled with a ground symbol and RAT on the EconoMi$er+ controller. See Fig. 22. The red wire of the harness is connected to pin 5 (ground). The black wire of the harness is connected to pin 6 (RAT). The wiring harness should be routed from the EconoMi$er+ controller to the sensor. The controller compares the temperatures of the two ai rstream s, chooses the be st one, and mod ulates the EconoMi$er+ actuator accordingly.

This 10K thermistor is used to measure the return air temperature vs. resistance curve, per Table 5. The range of temperature measurement is between 0° and 158 F. See Table 6 for resolution.

K. Outdoor Air Humidity Sensor

The EconoMi$er+ controller accepts input from the accessory outdoor air humidity sensor in ad dition to the out door air temperature sensor shipped with the EconoMi$er+. By using both sensors, the total ent halpy of the out sid e air is ca lcula ted.

Mount the outdoor-air humidity sensor in to the EconoMi$er+, through the pre-punched holes. See Fig. 28. The outdoor-air humidity senso r is provided with a 2-wire, 42-in. wiring harness with a 2-pin connector. The plug is installed on pins 11 and 12 on J3 of the EconoMi$er+ controller. The pins are labeled ORH and VREF on the EconoMi$er+ controller. See Fig. 22. The orange wire of the harness is connected to pin 11 (ORH). The blue wire of the harness is connected to pin 12 (VREF). The wiring harness should be rout ed from the Eco noMi$ er+ cont roll er to the se nsor location.

The outdoor enthalpy changeover curve is set at the EconoMi$er+ controller. The factory default is curve “A.” See Fig. 29. See Fig. 30 for Sensor Curve vs. Humidity.

L. Indoor Air Humidity Sensor

For differential enthalpy sensing, the EconoMi$er+ controller uses the standard outdoor air temperature sensor, the outdoor air humidity sensor, and the optional indoor air humidity sensor, an optional return air t emperature sensor (RAT). The indoor-air humidity sensor is provided with a 2-wire, 42-in. wiring harness with a 2-pin connector. The plug is installed on pins 8 and 9 on J3 of the EconoMi$er+ controller. The pins are labeled IRH and VREF on the EconoMi$er+ controller. See Fig. 22. The orange wire of the harness is connected to pin 8 (IRH). The blue wire of th e harness is connected to pin 9 (VREF). The wiring harness should be extended with wires and wire nuts and routed from the EconoMi$er+ controller to the sensor location. The EconoMi$er+ controller compares the outdoor air enthalpy to the return air enthalpy to determine EconoMi$er+ use.

M. Occupied/Unoccupied Switch

The EconoMi$er+ supports the use of a field-supplied occupied/

unoccupied switch. When the switch is closed it provides a

24-vac signal to the unit for occu pied mode and when open,

there is no signal to indicate unoccupied mode. The control can

be configured to allow di fferent m inimum e conomizer damper

positions and t o control how mechanical cool ing will and wi ll

not be used in the occupied mode.

NOTE: The remote potentiometer (see below) will overri de th e

occupied minimum position if the potentiometer setting is

greater than the occupied minimum position.

An occupied/unoccupied switch can be field-installed in place of the jumper to allo w the use r to forc e t he co ntrol i nto o ccupied or unoccupied mode of operation for EconoMi$er+ damper position. The occupied/unoccupied switch is required if the user wants to use unoccupied free cooling or different EconoMi$er+ damper vent positions in the unoccupied mode.

N. Power Exhaust

Refer to the Accessory Power Exhaust installation instructions for information o n i n stal ling the power exhaust acc es so ry.

O. Remote EconoMi$er+ Enable Control

When the control is used with energy management systems that enable and disable the EconoMi$er+, the user can install a fieldsupplied enable/disable switch. The switch must be wired in series with a 3K ohm, 1 watt or greater resistor. The switch is wired to terminals ORH (pin 11) and VREF (pin 12) on J3. Refer to the Start-Up section for details on how to configure the control.

P. R e mote Potentiometer Occupied Minimum Position

The occupied minimum position set point remote potentiometer (field-supplied) is used when requiring additional temporary ventilation. The remote potentiometer (10K ohm closed damper, 100K ohm - open damper) will only control the occupied minimum position.

The accessory 5-in wiring plug, CRE+PLUG001A00 is required to connect the potentiometer.

The plug is installed on pins 15, 16 and 17 on J3 of the EconoMi$er+ controller. The pins are labeled with the ground symbol, MIN and VREF on the EconoMi$er+ controller. See Fig. 22. The pink wire from the harness is connected to pin 15 (ground symbol). The gray wire fr om the harness is connected to pin 16 (MIN). The yello w wire from the harn ess is connected to pin 16 (VREF). The wiring harness should be extended with wires and wire nuts and routed from the EconoMi$er+ controller to the remote potentiometer location.

NOTE: Pins 13 (ground symbol) and 14 (IAQ), which are wired to the accessory 5-pin plug, are not used for the remote potentiometer installation. They are used for an accessory IAQ sensor (if required).

The unoccupied m ini mum posi tio n ca n onl y b e se t a t the co ntroller. The occupied minimum position set point configured at the EconoMi$er+ controller should be set to 0 when using a remote potentiometer. The occupied minimum position will also be used as part of the IAQ routing; it will be the maximum position the damper moves to when there is an IAQ call.

If the remote potentiometer (occupied) position is greater than the EconoMi$er+ controller unoccupied minimum position, then the remote potentiometer setting will be used. The remote potentiometer is field supplied and must be a 3-wire, linear potentiometer with a resistance between 10K ohm and 100K ohm (such as the Honeywell S963B1128).

Q.Demand Ventilation Control

Demand ventilation control uses an IAQ sensor (CRE+PLUG001A00 required) to control the amount of outside air admitted into the system. Normally, the minimum position of the EconoMi$ er+ damper is est ablished based on the demand occ upancy of the space. The IAQ s ensor wil l be used to modulate the EconoMi$er+ minimum damper position below the normal minimum position based on full occupancy. The lowe r li mit is called the base ventilation r at e. See Fig. 32.

If there is no IAQ signal the damper will be in the unoccupied minimum position (configuration item number 3). If there is an IAQ signal the damper will be in the occupied minimum position (configuration item number 15), unless the remote potentiometer is used to override it.

For the demand ventilation control logic, the user configures the lower and upper actuator position to establish the base ventilation rate (IAQMIN_SP) and the de sign ventilation rate (ECONOMIN_SP) for full occupancy. When the EconoMi$er+ damper is being modulated for demand ventilation control, the damper position will be between IAQMIN_SP and ECONOMIN_SP. The upper IAQ differential set point is DAQHI. The lower IAQ differential set point is DAQLO.

The differential set points represent the differential CO level (in ppm) above the outdoor reference IAQ le vels. Normally, the outdoor ref er ence IAQ le vel s ar e a ro und 4 0 0 ppm , but the value should be configured based on the reference levels taken at the job site.

5. Press Mode to move through the variables.

6. Press Enter to lock in the selection, then press Mode to continue to the next variable.

S. Dehumidification of Fresh Air with Demand Control Ventilation (DCV)

Information from ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) indi cates that

the largest humidity load on any zone is the fresh air introduced. For some applications, a device such as a energy recovery unit is added to reduce the moist ure content of the fresh air being brought into the building when the enthalpy is high. In most cases, the normal heating and cooling processes are more than adequate to remove the humidity loads for most commercial applications.

This makes the control of the dehumidification device simple when using the enthalpy or differential enthalpy sensor. The enthalpy sensor or diffe rential enthalpy sensor is installed on the equipment to determine economizer operation. The high enthalpy signal from the temperature and humidity sensors or differential temperature and humidity sensors can be used to turn on the outdoor air moisture removal device any time fresh air is required for the space.

The energy recovery device should be sized for maximum latent and sensible conditioning at maximum ventilation on a design day.

A calculation for leaving-air temperature on a low ambient, low ventilation day should also be done to determine the supply-air temperature of the return and pre-conditioned outside air. The design should produce air temperature somewhat near room conditions to prevent reheat of the air mixture. The energy recovery device should be interlocked with the heat to turn off the device when in the heat mode.

PRE-START-UP

WARNING: Failure to observe the following warn-

ings could result in serious personal injury.

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 comp ressor terminal cover until all electrical sou rc e s are disco nnected.

4. Relieve all pressure from system before touching or disturbing anything inside terminal box if refrigerant leak is su spe cte d arou nd c ompre ssor terminals.

5. Never attempt to repair soldered connection while refrigerant system is under pressure.

6. Do not use torch to remove any component. System contains oil and refrigerant under pressure. To remove a component, wear protective goggles and proceed as follows:

a. Shut off electrical power and then gas to

unit.

b. Reclai m refrigerant to relie ve all pressure

from system using both high- and lo w-pre ssure ports.

c. Cut component connection tubing with tub-

ing cutter and remove component from unit.

d. Carefully unsweat remaining tubing stubs

when necessary. Oil can ignite when exposed to torch flame.

Proceed as follows to ins pect and prep are the unit f or initial start-up:

1. Remove all access panels.

2. Read and follow instructions on all WARNING, CAUTION, and INFORMATION labels attached to, or shipped with, unit.

3. Make the following inspections:

a. Inspect for shipping and handling damages such

as broken lines, loose parts, or disconnected wires, etc.

b. Inspect for oil at all refrigerant tubing connec-

tions 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.

c. Inspect all field-wiring and factory-wiring con-

nections. Be sure that connections are completed and tight. Be sure that wires are not in contact with refrigerant tubing or sharp edges.

d. Inspect coil fins. If damaged during shipping and

handling, carefully straighten fins with a fin comb.

4. Verify the following conditions:

a. Make sure that condenser-fan blade are correctl y

positioned in fan orifice. See Condenser-Fan Adjustment section on page 62 for more details.

b. Make sure that air filter(s) is in place.

c. Make sure that condensate drain trap is filled

with water to ensure proper drainage.

d. Make sure that all tools and miscellaneous loose

parts have been removed.

START-UP

I. UNIT PREPARATION

Make sure that unit has b een installed in accordance with these installation instructions and applicable codes. Make sure that Start-Up Checklist, located on back page of this booklet, has been completed and filled out.

II. RETURN-AIR FILTERS

Make sure correct filters are inst alled in filter trac ks (see T ables 1A and 1B). Do not operate unit without return-air filters .

III. OUTDOOR-AIR INLET SCREENS

Outdoor-air inlet screens must be in place before op erating unit.

IV. COMPRESSOR MOUNTING

Compressors are internally spring mounted. Do not loosen or remove compressor holddown bolts. On 580F150 and 151 units, remove the tiedown bands that hold the compressors together.

V. INTERNAL WIRING

Check all electrical connections in unit control boxes. Tighten as required. Ensure wiring does not come into direct contact with refrigerant tubing.

VI. GAS PIPING

Check gas piping for leaks.

WARNING: Disconnect gas piping from unit when

leak testing at pressure greater than

/2 psig. Pressures greater tha n 1/2 psig will cause g as valve damage resulting in hazardous condition. If gas valve is subjected to pressure greater than

/2 psig, it must be replaced before use. When pressure testing fieldsupplied gas piping at pressures of

/2 psig or less, a unit connected to such piping must be isolated by manually closing t he ga s valve.

VII. REFRIGERANT SERVICE PORTS

To service refrigerant service ports, remove compressor access panel. Each unit system has 3 Schrader-type service gage ports: one on the suction line, one on the liquid line, and one on the compressor discharg e line. Be sure that caps on the ports are tight. The Schrader-type valve on the discharge line is located under th e low-pressu re switch. Anoth er valve is located on the discharge line underneath the highpressure switch. It is screwed on a Schrader fitting but there is no Schrader core.

VIII. HIGH FLOW VALVES

Located on the compressor hot gas and suction tubes are High Flow Valves. Large black plastic caps distinguish these valves with O-rings located in s i de th e ca p s. These valves can not be accessed for service in the field. Ensure the plastic caps are in place and tight or the possibility of refrigerant leakage could occur.

IX. COMPRESSOR ROTATION

On 3-phase units with scroll compressors, it is important to be certain compressor is rotating i n the proper direc tion. 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 compressor.

3. The suction pressure should drop and the discharge pressure should rise, as is normal on any start-up.

—50—

Page 51

If the suction pressure does not drop and the discharge pressure does not rise to normal levels:

1. Note that the evaporator fan is probably also rotating in the wrong direction.

2. Turn off power to the unit and install lockout tag.

3. Reverse any two of the unit power leads.

4. Reapply power to unit. Reen ergize compressor.

The suction and discharge pressure levels should now move to their normal start-up levels.

NOTE: When the compressor is rotating in the wrong direction, the unit will make an elevated level of noise and will not provide cooling.

X. COOLING

To start unit, turn on m ain power supply. Set system selector switch at CO OL positi on and fan switch at AUT O. position. Adjust thermostat to a setting below room temperature. Compressor, indoor and outdoor fans start on closure of contactors.

Check unit charge. Refer to Checking and Adjusting Refrigerant Charge section, page 62. Unit must operate a minimum of 10 minutes before adjusting charge.

Reset thermostat at a position above room temperature. Compressor and outdoo r fans will shut off. Evaporator fan will shut off after 30-second delay.

A. To Shut Off Unit

Set system selector switch at OFF position. Resetting thermostat at a positio n above room temperature sh uts unit off temporarily until space temperature exceeds thermostat setting.

XI. MAIN BURNERS

Main burners are factory set and should require no adjustment.

TO CHECK ignition of main burners and heating controls, move thermostat set p oint abo ve room t emperat ure and ve rify that the burne rs light and evaporator fan is energized. After ensuring that the unit continues to heat the building, lower the thermostat setting below the room temperature and verify that the burne rs and evapor ator fan turn off ( fan will turn off only if fan selector switch is in the AUTO. position). Refer to Table 31 for the correct orifice to use at high altitudes.

NOTE: Upon a call for heat, the main burners will remain on for a minimum of 60 seconds.

A. Adjust Gas Input

The gas input to the unit is determined by mea suring the gas flow at the m eter o r by me asuri ng th e ma nifold pres sure . Manifold pressure should be 3.5 in. wg. in high-fire operation.

NOTE: Unit uses a 2-stage gas valve. There is no need to adjust the “Low Fire” manifold pressure.

Measure Gas Flow (Natural Gas Units) Minor adjustment to the gas flow can be made by changing

the manifold pressure. The manifold pressure must be

3.5 in. wg. Normal manifold pressure is 3.5 in. wg in high fire (W1 and W2 inputs to gas valve).

Proceed as follows:

1. Turn off gas supply to unit.

2. Remove pipe plug on manifold then connect manometer at this point. Turn on gas to unit. Ensure gas valve is in high fire operation.

Observe manifold pressure in high fire (W1 and W2 energized) and proceed as follows to adjust gas input:

1. Remove cover screw ove r regulator a djustment s crew on gas valve. Ensure gas valve is operating in high fire mode.

2. Turn regulator adjustment screw clockwise to increase gas input, or turn regulator adjustment screw counterclockwise to decrease input. High fire manifold pressure must be 3.5 in. wg.

WARNING: Unsafe operation of the unit may result if manifold pressure is outside 3.4 to 3.6 in. wg range. Personal injury or unit damage may result.

3. Replace cover screw cap on gas valve.

4. Turn off gas supply to un it. Rem ove m anometer from pressure tap and replace pipe plug on gas valve. Turn on gas to unit and check for leaks.

XII. HEATING

1. Purge gas supply line of air by opening union ahead of gas valve. When gas odor is detected, tighten union and wait 5 minutes before proceeding.

2. Turn on electrical supply and open manual gas valve.

3. Set system switch selector at HEAT position and fan switch at AUTO. or ON position. Set heating temperature lever above room temperature.

4. The induced-draft motor will start, purging heat exchangers.

5. After a call for heating, the main burners should light within 5 seconds. If the burners do not light, then there is a 22-second delay before another 5-second ignition try. If the burners still do not light, the time delay is repeated. If the burners do not light within 15 minutes, there is a lockout. To reset the control, break the 24 v power to W1.

6. The evaporator-fan motor will turn on 45 seconds after the burners are ignited.

7. The evaporator-fan motor will turn off 45 seconds after the thermostat temperature is satisfied.

8. Adjust airflow to obtain a temperature rise within the range specified on the unit nameplate and in Tables 1A and 1B.

XIII. INTEGRATED GAS CONTROLLER (IGC) OPERATION

NOTE: The default value for the evaporator-fan motor ON

and OFF delay is 45 sec ond s. The I ntegr ate d Gas Con trol ler (IGC) modifies this valu e when a bnormal limi t switch cycl es occur. Based up on unit operating conditions, the O N delay can be reduced to 0 seconds and the OFF delay can be extended to 180 seconds.

When one flash of the LED (light-emitting diode) is observed, the evap orator-fan ON/OFF del ay has been modified. If the limit switch trips at the star t of t he he ating cycle during the evaporator ON delay, the time period of the ON delay for the next cycle will be 5 seco nds less than the time at which the switch tripped. (Example: If the limit switch trips at 30 seconds, the evaporator-fan ON delay for the next cycle will occur at 25 seconds.) To prevent short-cycling, a 5-second reduction w ill only occur if a minimum of 10 minutes has elapsed since the last call for heating.

The evaporator -fan O FF dela y can also be m odified. O nce th e call for heating has ended, there is a 10-min ute period during which the modification can occur. If the limit switch trips during this period, the evaporator-fan OFF delay will increase by 15 seco nds on the next cycle. A maximum of 9 trips can occur, extending the evaporator-fan OFF delay to 180 seconds. To restore the original default value, reset the power to the unit.

A. To Shut Off Unit

Set system selector sw itch at OFF p osition. Re setting h eating selector lever below room temperature will shut unit off temporarily until space temperature falls below thermostat setting.

XIV. SAFETY RELIEF

A soft-solder joint at the suction l ine Schrader port provi des pressure relief under abnormal temperature and pressure conditions.

XV. VENTILATION (Continuous Fan)

Set fan and system selector switches at ON and OFF positions, respectively. Evaporator fan operates continuous ly to provide constant air circulation. When the evaporator-fan selector switch is turned to the OFF position, there is a 30-second del a y be f or e th e f an tur ns off.

XVI. ECONOMI$ER+ CONTROLLER

The EconoMi$er+ controller is mounted to the top of the EconoMi$er+ d amp er and is acce ssibl e by remo ving the fi lter access door of the unit.

The EconoMi$er+ controller is protected by a sheet metal enclosure mounted over the controller. Remove the single screw on the front of the enclosure and lift off the top for access to the contro ller. The primary purpose of the control ler is to provide cont rol of the EconoMi$er+ da mpers and the cooling compression stages. The status of the indoor fan is monitored through the G input but is n ot directly cont rolled by the controller. The heating function is completely independent of the controller.

IMPORTANT: The controller can only be used with conventional thermostats with Y1, Y2 and G input to the controller; it can NOT be used with electroni c thermostats with a proportional room temperature input, or with Variable Air Volume systems.

There are 4 LEDs on the controller, which are used to read values and display status and configuration information. There are 2 buttons (READ/ADJUST and ADVANCE/MANUAL), which change modes and configure the controller . See Fig. 36.

The EconoMi$er+ microprocessor based control system provides the following control functions:

• EconoMi$er+ damper control for free cooling

• Minimum position control for ventilation

• Demand Ventilation Control using a CO

sensor

• Compressor Cooling Stage Control

• Occupied/Unoccupied Control

• Diagnostics Display and History

• Manual test control See Table 32 for Inputs and Outputs.

A. Integrated Display

The control board includes an integrated display, which is used for the following functions:

• Configuration and setup

• Set point and control adjustment

• Error status and alarm monitoring

• Manual control

• Reading sensor values There are 5 modes of display operation:

•Startup Mode

•Run Mode

• Read Mode

•Setup Mode

• Manual Mode External devices are not required to operate and configure

the control.

B. Startup Mode

During the first 3 secon ds after power is applied to the control, the four LEDs flash as shown in Table 33, indicating that the control is being initialized. The buttons are not operational during Startup mode.

C. Run Mode

Run mode indicates status of control ler and unit. The mode can be changed to the Read, Setup, or Manual modes by pushing va ri ous buttons.

While the control is in Run mode, the DS1 heartbeat indicator LED (red) will flas h to indi cat e the cont rolle r is ope rat ing properly. The DS2 Econo indicator LED (yellow) will flash whenever econom ize r is b ein g us ed f o r fre e co olin g. The DS3 first stage cooling indicator LED (green) will be on steady indicate demand for sta ge 1 cooling. The DS4 second stage cooling indicator LED (green) will be on steady to indicate demand for stage 2 cooling.

If the controller is in a different mode, the controller will return to Run mode after 10 minutes of user inactivity or if the READ/ADJUST (#1) and ADVANCE/MANUAL (#2) buttons are held for at least 3 seconds until all LEDs flash.

D. Read Mode

Read mode is used to check set points (Table 34) and I/O channel status (Table 35). Enter the Read mode by pushing and releasing the READ/ADJUST (#1) button. A user can only enter Read mode from the Run mode (to get to Run mode, press both the #1 and #2 buttons for at least 3 seconds until all LEDs flash). In Read mode, LEDs are not lit until the READ/ADJUST button (#1) is pushed.

NOTE: If the user pushes and holds the READ/ADJUST button (#1) for more than 3 seconds, then the control will go into the Setup mode, indicated by the yellow LED (on steady).

While in Read mode, push button #1 then the DS1 LED (Red) flashes to indicate setup point number as defined in the setup table. The two green LEDs will then show the value of the display item. The DS3 LED will first display the

—52—

Page 53

tens digit and the DS4 LED will then display the ones digit. For example to display 54, the DS3 LED will flash 1 group of 5 at a high flash rate to indicate 50, and then follow with 4 flashes (DS4) at 1-second intervals to complete the display of the number 54.

NOTE: Do not try to count the “5 Fast Flashes” individually, but instead count how many groups of 5 flashes were displayed. In this case, 1 group of 5 flashes, plus the 4 flashes at 1 second results in the value of 54.

To re ad the di splay again, push the READ/AD JUST (# 1) button and the sequence will repeat as many times as needed.

To advance to the next setup point, push the ADVANCE/ MANUAL (#2) button. The controller will cycle throu gh all the setup channels (Table 34) and then the I/O channels (Table 35) and then back to the first setup channel.

NOTE: Th e user can only advance forw ard, no t reset to # 1 or go backwards. Cycling the EconoMi$er+ power will reset the item number (but not the item value) to item #1.

In the Read mode for setup variables, the LEDs will not turn on steady; the LEDs will always flash. Steady-on indicators are reserved for the configuration modes. No data is modified in the Read mode. The con troller will always remain at the last read number even if reset back to normal operat ion.

NOTE: To enter another mode, the user first must exit the Read mode.

If no button is pushed in 10 minutes, Read mode will automatically be exited. Also, if the READ/ADJUST (#1) and ADVANCE/MANUAL (#2) buttons are pushed and held for more than 3 seconds, then Read mode will be exited to Run mode. While i n the Read mod e , the c ontro ller will conti nue to operate with normal unit control.

After advancing through all the configuration variables in the Read mode, the controller will then advance through t he status of the I/O channels. As in the Read mode, there will be no LEDs on. Push the READ/ADJUST (#1) button and the yellow LED will flash the “I/O Point” numbe r and the green LEDs will flash the “I/O Values” in the same manner described in the Read mode section. See Ta ble 35. At the first I/O point (Compressor 1 Ou tput), the DS2 LED (Yellow) will flash with the number of the I/O channel and the DS1 LED (red) will stop fla shi ng. This will be followed b y the I/O c h annel status. To read the value ag ain, pus h the R EAD/ADJU ST (#1) button.

To advance to the next channel, push the ADVANCE/ MANUAL (#2) button. If the number of the channel or the status value is greate r than 4 the controller will co unt out the increments of 5 at a high flash rate followed by the remaining digits. The channel number will be counted out through the DS2 LED (yellow). The status value will be counted out through the DS3 and DS4 LEDs (green).

If the status value is an analog value then the numeric value will be displayed by using the DS3 Green LED to display the tens digit and the DS4 will be used to display the ones digit.

If the channel is a digital output (relay), the DS3 LED (flashing green) will in dicate ON stat us and the DS4 LED (flashing green) will indicate OFF status. If the output is the economizer control signal then the DS3 LED will be used to indicate the motor is being driven open, and the DS4 LED will be used to indicate it is being closed. If the motor i s not being commanded in either direction then both the DS3 and DS4 LEDs will be on. The controller will first go through the output relays, then the economizer motor, and will then fol low with the values currently being read for the analog input channels as defined in the configuration table. All values are maintained in memory even during a power loss. To exit Setup mode, push and hold the READ/ADJUST (#1) and ADVANCE/MANUAL (#2) buttons for more than 3 seconds. Setup mode wil l automati cally be exited aft er 10 minu tes of no activity.

E. Setup Mode

The Setup mode is used to change set points and configuration values.

Enter the Setup mode by pushing and holding the READ/ ADJUST (#1) button 1 for at least 3 seconds until all LEDs flash once. Then, the yellow LED will come on steady. A user can only enter the Setup mode from the Run m ode (to get to Run mode, press buttons both buttons #1 and #2 for at least 3 seconds).

In Setup mode, all configurations can be modifi ed e ven w hil e the unit is running, but the use r will not be able to adjus t the I/O channels . O nly c ha nne ls 1 th roug h 20 on Table 34 will b e accessible in the Setup mode. Channel 20 will be used to reset any alarms that may have occurred. As an option, alarms can also be reset by cycling power to the cont roller.

NOTE: During the Se tup mode, all routines including safety routines will co ntinu e to ru n a nd c ontr ol the uni t.

While in this mode, the DS1 LED (red) will flash to indicate the number of the configuration item. The DS2 LED (yellow) will be on continuousl y to i ndi cate tha t the uni t is i n c on figuration mode. Use the ADVANCE/MANUAL button to sequence through the setup channels. If the value of the channel is less than 5 it will count out the value of the channel on the DS1 LED at 1-second intervals. If the channel value is 5 or great er, the DS1 LED will first c ount out the groups of 5 and then following with the remaining digit.

Verify what Setup Point is being read by pushing the READ/ ADJUST button (#1). First the Red LED will flash the set point number, then the Green LEDs will flash the value. Then, the green DS3 and DS4 LEDs will each come on steady for about 2 seconds. While DS3 is on steady, its new value can be entered by pushing READ/ADJUST (#1), and entering the value for the ten’s digit. When the DS4 comes on steady, enter the value for th e one's d igit. Afte r the green LEDs are off, push the READ/ADJUST button (#1) again to verify that the correct value has been entered. If the configuration is a discrete On/off setting, push the READ/ADJUST button (#1) to toggle LED 3 or 4 on or off.

Setup Example 1: Change “Occupied Minimum Position” (configuration item 2) to 53%.

1. Read the General Notes about reading and entering values found on the label on the top of the EconoMi$er+.

2. Push and hold button #1 (READ/ADJUST) for at least 3 seconds until all LEDs flash. The yellow LED will go on steady.

3. Read the current configuration point by pushing button #1. The red LED flashes the configuration point number and the green LEDs flash the current setting for that setup point number.

4. On the label (on top of the EconoMi$er+), read Step 2 and Note 1 for Setup mode operation.

5. Use button #2 (ADVANCE/MANUAL) to advance to configuration point number 2, Occupied Min.

NOTE: Before performing Step 6, be ready to push button #1; there is a limited time window that can easily be missed when the DS3 green LED comes on, and agai n when the DS4 green LED comes on.

6. Verify the configuration point by pushing button #1. The red LED should flash twice to indic ate point 2, and then the green LEDs will flash the current setting.

7. Next, the green DS3 LED wil l turn on steady for 2 seconds. During this time, push button #1 five times.

8. The DS3 LED wi ll turn off and the gree n DS4 LED will go on steady for 2 seconds. During this time, push button #1 three times.

9. The 5 button #1 pushes, followed by the 3 button #1 pushes is the sequ ence that sets the occupied mini mum position to 53%.

10. Wait until the green LEDs turn off then verify the setting by pushing button #1 to read the value. There should be 5 fast blinks of DS3 and 3 slow blinks of DS4.

Setup Example 2: Change the Occupied Minimum Position (item 2) to 2% (lowest value).

1. Read the General Notes about reading and entering values found on the label on the top of the EconoMi$er+.

2. Push and hold button #1 (READ/ADJUST) for at least 3 seconds until all LEDs flash. The yellow LED will go on steady.

3. Read the current configuration point by pushing button #1. The red LED flashes the configuration point number and the green LEDs flash the current setting for that setup point number.

4. On the label (on top of the EconoMi$er+), read Step 2 and Note 1 for Setup mode operation.

5. Use button #2 (ADVANCE/MANUAL) to advance to configuration point number 2, Occupied Min.

6. Verify the configuration point by pushing button #1. The red LED should flash twice to indicate point 2, and then the green LEDs will flash the current setting.

NOTE: Since the occupied minimum position MUST be 1 greater than the IAQ minimum position (item 15), the IAQ minimum position must be changed first. (IAQ min has a default value of 5%, whi ch is higher tha n the 2% value i n this example.)

7. Use button #2 (ADV ANCE/MANUAL) to get to configuration point 15 (IAQ Minimum Position).

NOTE: Before performing Step 8, be read y to pus h button #1; there is a limited time window that can easily be missed when the DS3 green LED comes on, and again wh en the DS4 green LED comes on.

8. Verify the configuration point by pushing button #1. The red LED should flash 15 times to indicate point 15, then the green LEDs will flash the current setting.

9. Next, the green DS3 LED will turn on steady for 2 seconds. During this time, do NOT do anything so that the position defaults to 0.

10. The DS3 LED will turn off an d the green DS4 LED will go on steady for 2 seconds. During this time, push button #1 once to set the point to 1%.

11. Wait until the green LEDs turn off then verify the setting by pushing button #1 to read the value. DS3 should not blink, and DS4 should blink once.

12. Now configure the Occupied Minimum Position to 2%. Use button #2 (ADVANCE/MANUAL) to get to configuration point 2.

NOTE: Before performing Step 13, be ready to push button #1; there is a limited time window that can easily be missed when the DS3 green LED comes on, and again wh en the DS4 green LED comes on.

13. Verify the configuration point by pushing button #1. The red LED should flash twice to indicate point 2, then the green LEDs will flash the current setting.

14. Next, the green DS3 LED will turn on steady for 2 seconds. During this time, do NOT do anything so that the position goes to 0.

15. The DS3 LED will turn off an d the green DS4 LED will go on steady for 2 seconds. During this time, push button #1 twice to set the point to 2%.

16. Wait until the green LEDs turn off then verify the setting by pushing button #1 to read the value. DS3 should not blink, and DS4 should blink twice.

NOTE: Configuration items 2, 15, 11, 12, 18 and 19 (in Tabl e 34) are dependent upon other items . Before attempting to change one of these items, be sure to check the value of the item it depends upon (as described in Example 2 above).

IMPORTANT: During SETUP MODE, changes are allowed when the DS3 LED and DS4 LED are lit for 2 seconds (as described in Example 1 and 2 above). During this time, if button #1 is pushed to change one position and not the other, the value for that one position will change and the oth er will default to zero (unless a dependency prevents the zero). However, if button #1 is not pushed at all during the 2 seconds that the green LEDs are lit, the configuration item will not change.

F. Manual Mode

Manual mode is used to contr ol the status of I/O channels for use in troubleshooting. See Table 35.

Enter the Manual mode by holding down the ADVANCE/ MANUAL (#2) button for at least 3 seconds until all LEDs flash and then the red LED comes on steady.

NOTE: A user can only enter the M anual mode from the Run mode, which is entered by pushing buttons #1 and #2 for at least 3 seconds.

All EconoMi$er+ c ontrol output s are tu rned off. “I/O Inputs” 1-5 can be adjusted even if the unit is in operation.

In manual mode, the yellow DS2 LED flashes once to indicate the I/O channel. See Table 35. If the value is less than 5, the yellow DS2 LED will count out the value using 1-second flashes. If the value is greater than 4, the yellow DS2 LED will count out groups of 5 at a high flash rate and then follow with the additional value at a flash rate of once per second. For example a flash of 1 indicates Compressor Relay Output 1.

Push READ/ADJUST button (#1) to read the value. The yellow LED will flash the I/O Ch annel number being viewed.

Once the channel number is displayed it will then turn on the appropriate green LED (DS3 or DS4) to i ndicate the status of the output. For relay outputs i f the DS3 LED is on, then the output is on. If DS4 is on, then the output is off. The green DS3 and DS4 LEDs will remain on for about 2 seconds and if during this time the READ/ADJUST (#1) button is pushed, then the output will toggle to the alternate state. To change again, push the READ/ADJUST button and re peat the test or change the status of the output. As an example, for channel 5 (EconoMi$er+ control damper motor) use the READ/ADJUST button to toggle the motor from open to close in %.

At any time, the ADVANCE/MANUAL (#2) button can be used to advance to the next SET I/ O. To exit the mode, push and hold the READ/ADJUST and ADVANCE/MANUAL buttons (#1 and #2) for more than 3 seconds.

NOTE: After exiti ng the Manual mode, the controller will reinitialize and start with all outputs off.

G. Error Mode

The error mode is used to indicate that an error has occurred The error is indicated by LED #1 red and #2 yellow are on steady.

Enter the RUN mode by pushing the READ/ADJUST and ADVANCE/MANUAL buttons (#1 and #2) for at least 3 seconds until all LEDs flash. Next, push and release button #1 to enter the Read mode. Then push button #2 to advance to item 20 (“first most recent error”). Determine the e rror by reading the value in items 20 to 24 and referring to the Troubleshooting sect io n.

Once the error has b een fixed, pres s buttons #1 and 2 for at least 3 second s to exit Read mode. All LEDs will flash.

Enter Setup mode by pressing the READ/ADJUST button (#1) for at least 3 seconds. All LEDs will flash. Push the ADVANCE/MANUAL button (#2) to advance to item 20. Push READ/ADJUST to read item 20.

To reset the error code while the green DS4 LED is on, press the READ/ADJUST button (#1) once. In addition to resetting the error mode, this will er ase all error codes. Cycling the power will also erase the error code.

XVII. ECONOMI$ER+ CONFIGURATION

For most applications, the factory setting will be used to control the EconoMi$er+. How ever, there are 19 differe nt variables that can be used to co nfig ure the control for wide r a nge of applications. The factory settings and variables are shown in Table 34.

IMPORTANT:

There is no way to reset/restore the factory default configurations; use caution when making changes to any set point or operational variable.

The EconoMi$er+ control accepts an occupied/unoccupied switch input. This input is used to control the occupied and unoccupied minimum ventilation damper position as shown in Table 34 items 2 (ECONOMIN_SP) and 3 (U_ECONOMIN_SP). These values represent the minimum damper position. In addition, the controls allows for different modes of compressor operation in the unoccupied mode. Using item 13 in Table 34 (OCC_MODE), the user can select one of the following unoccupied modes:

• No unoccupied cooling

• Unoccupied free cooling (EconoM i$er+)

• Unoccupied free cooling and mechanical cooling The EconoMi$er+ will control the cooling operation of the

unit based on the demand from the thermostat outpu ts Y1 and Y2. The EconoMi$er+ will monitor the fan output G, but will not control the fan directly. Note that G must be energized for any cooling to take place. Gas or electric heating will be controlled dire ctly from the thermostat.

When a demand for coo ling occurs, the control will check to see if it is in the occupied or un occupied mode. Depen ding on the configuration, the control will move the outdoor air damper to the vent ilation position . If the outdoor a ir conditions are acceptable, then the control will use the EconoMi$er+ for free c ooling. If the supply-air temper ature does not meet the configurable set point, then the control will turn on additional stages of mechanical cooling. Several compressor sequences can be used depending on the application requiremen ts; these will be covered in t he mechanical compressor staging section.

A. Compressor Configuration And Control

The EconoMi$er+ control can support fro m 1 to 4 compressor stages. For the 3 to 12 2 stages of compressor cooling, so the control is factory configured for 2 stages. There is no difference between 1 and 2 stages. The control also provides the option to configure for high sensible o r hi gh latent loads , but for units with o nl y t wo compressors this option does not apply.

Compressors are co nfigured using item 10 (STAGE_TYPE) in Table 34. The control also has the capability of controlling directly to Y1 and Y2 inputs. The contr ol can be configured to control to the leaving-air temperature using Y1 and Y2 as a low cool and high cool demand based on the supply air set point and the rate of change of supply-air temperature. For low cool the leaving air temperature set point will be SAT_SP +2° F. For high cool the leaving air temperatur e set point will be the supply-air temperature set point (SAT_SP).

To use this option, configure the compressor sequencing variable (STAGE_ TYPE ) to a valu e of 3. Con figur e the supply air temperature set point (SAT_SP) to the desired leaving air temperature.

NOTE: The supply air temperature s et point is also the temperature used for EconoMi$er+ control.

The logic will control the operation of the compressors depending on the configuration selected. If free cooling can be used, then the compressors will be integrated with the EconoMi$er+ to provide the lowest cost cooling control. The

/2 ton units, there will only be 1 or

logic includes time guards on the compr essors to provide a minimum of 3 minutes on and 3 minut es off time. T he control will also prevent two compress ors from starting at the same time. The logic uses th e Econo Mi$er+ to pre vent r apid cycling of the compressors and l ow air temperatures.

B. Ventilation Air And Free Cooling

In order for the EconoMi $er+ to control ventilation air and free cooling, several items must be configured.

EconoMi$er+ Type First, select the EconoMi$e r+ control type that will be used.

This is the EconoMi$er+ Type function (ECONO_TYPE) defined by item 5 in Table 34. The choices are:

1. Vent only — This is used to have just ventilation control. The EconoMi$er+ will not provide free cooling, but the occupied and unoccupied minimum positions can be used.

2. Proportional — In this configuration, full proportional EconoMi$er+ control will be used. When EconoMi$er+ free cooling cannot be used, the dampers will be set to the appropr iat e occ upie d and unoc cupied minimum positions.

3. Three-Position — This mode of EconoMi$er+ is used to provide a mini mum venti lation Ec onoMi$e r+ position and a fixed free cooling or high ventil ation position. The high ventilation position is controlled by the optional Remote EconoMi$er+ Enable Switch Input connected to terminals 11 and 12 on T3.

Supply Air Temperature Set Point Once the type of Econ oMi$e r+ cont rol ha s been selecte d, the

user will need to set the Supply Air Temperature set point (SAT_SP). The SAT_SP has a range of 40 to 65 F.

NOTE: This will be the set point when both Y1 and Y2 are closed. When just Y1 is closed, the set point will be ° F higher.

Minimum Damp er Position Set the occupied mi nimum damper position (E CONOMIN _SP)

and unoccupied minimum position (U_ECONOMIN_SP). These should be set t o pr ov ide the ventilation requirements at full occupancy as defined by the building specifications. When demand ventilation is used, the control will close the dampers below this position based on measur ed CO to provide additional operation savings.

The control wil l also a llow for the use o f a remo te mini mum position potentiometer. This will only adjust the Occupied Minimum position. If used, the software set point ECONOMIN_SP sho uld be se t to 0 as the contr ol wi ll use the largest set point.

The damper position is not linear with the amount of outside air, so the user will need to set the position of the EconoMi$er + acco rdi ngly. It is best to use the fo llow ing equ ation and measured data to set the position:

SAT – RAT

OA =

OAT – RAT

OA = % outdoor air SAT = supply air temperature RAT = return air temperature OAT = outdoor air temperature

The SAT and OAT val ues can be read from the control and, if the unit is equipped with an RAT sensor, then all three values can be read. For the calculation to work properly, there should be at least a 10° F difference between the OAT and RAT temperatures.

Page 59

Maximum Damper Position Set the maximum EconoMi$er+ position. Normally this is

set at 100%. If using 3-position control or there is a reason not to use 100% outside air, this can be set using the EconoMi$er+ Maximum Position (MAX_POS_SP).

Compressor Lockout Temperature Set the Compressor Lockout Temperature. The Compressor

Lockout Temperature (CMP_LOCK) is used to prevent compressor from running at low ambient conditions when an EconoMi$er+ can easily satisfy the load.

EconoMi$er+ Changeover Control Determine the type of EconoMi$er+ changeover control

which will be used to enable and disable free cooling. This is done using the EconoMi$er+ Changeover Type.

1. Switch — This changeover setting is used when a remote signal from an energy management system will enable and disable the EconoMi$er+. This is done through a remote EconoMi$er+ enable switch.

2. Outdoor Dry Bulb — For this changeover setting, the EconoMi$er+ w ill be en abled b ase d on the ou tdo or-air temperature. The EconoMi$er+ is shipped with an outdoor air temperature sensor. The outdoor air temperature set point can be configured by th e user. The EconoMi$er+ will be disabled when the outdoor-air temperature rises above the set po int. The co nfiguration variable is the EconoMi$er+ Changeover set point (OAT_SP).

3. Differentia l Dry Bulb — For this changeover setting, the EconoMi$er+ will be en abled whenever the outside-air temperature is lower than the return-air temperature. No configuration of set points is required other than to sel ect the differe nt ial dry bu lb function.

4. Outdoor Enthalpy — For this changeover setting, the control will enable the EconoMi$er+ based on the outdoor-air enthalpy curves as shown in Fig. 29. Using the EconoMi$er+ Changeover set point (ENTHALPY_SP), select curves A, B, C or D. The control will then use the EconoMi$er+ at conditions below the curve. The control uses the OAT and optional humidity sensor to calculate the enthalpy and also has the A, B, C, and D curves stored in memory.

5. Differential Enthalpy — For this changeover setting, the EconoMi$er+ will be enabled based o n the comparison of the enthalp y of the return air and outs ide air. If the outside air enthalpy is lower than the return air, then the EconoMi$er+ will be enabled. To use this option, an accessory outside air humidity sensor, a return air dry bulb sensor and a return air humidity sensor must be ordered and installed. No configuratio n of set points is required other th an to select the function.

C. Demand Ventilation Configuration

The EconoMi$er+ control has demand ventilation control capability when using an IAQ sen sor. The indoor air qualit y (IAQ) is measured using a CO

sensor. The IAQ sensor can

be field-installed in the return duct or the occupied space. The EconoMi$er+ control algorithm modulates the po sition

of the EconoMi$er+ damper between two user configurations depending upon the relationship between the IAQ and the Outdoor Air Quality (OAQ). The lower of these two positions is referred to as the Min imum IAQ Min imum EconoM i$er+ Position (IAQMIN_SP).

The higher position is referred to as the Occupied EconoMi$er+ Minimum Position (ECONOMIN_SP). The IAQMIN_SP should be set to an EconoMi$er+ position that brings in enough fresh air to remove contaminants and CO

generated by sources

other than people. The ECONOMIN_SP should be set to an EconoMi$er+ position that brings in enough fresh air to remove contaminants and CO

generated by all sources including peo-

ple at the design value for maximum occupancy. A reference differential CO

level above the outside CO

level is used as the starting point for IAQ control and another reference differential level for maximum ventilation at design occupancy is used for the end of IAQ control. Between these points the control wi ll modulate the da mpers open from the IAQMIN_SP and the ECONOMIN_SP setpoints. The damper position will never go above ECONOMIN_SP or below IAQMIN_SP.

The control does not measure the outdoor IAQ reference level as these levels are relatively constant. The installer should take a measurement at start-up of the unit and enter this value into the control using the Outdoor Air IAQ reference level configuration.

The control is configured for air quality sensors which provide 4 mA at 0 ppm and 20 mA at 2000 ppm. If a sensor has a different range, these bounds must be reconfigured.

To configure the control for an IAQ sensor perform the following steps:

1. Determine the Occupied EconoMi$er+ Minimum position (ECONOMIN_SP) and enter it into the control.

2. Determine the IAQ minimum EconoMi$er+ position (IAQMIN_SP) and enter it into the control.

3. Enable IAQ control using IAQ Enable (IAQ_FL G ).

4. Determine the Outdoor Air IAQ Reference (OAQ) and enter it into the control.

NOTE: The value entered into the control will be the CO ppm level divided by 10. For example, 400 ppm would be entered as 40.

5. Determine the lower control point differential level (DAQLO) and enter it i nto the control. This is a differential level so if the desired level to start IAQ control is 500 ppm and the OAQ reference level is 400 then a value of 100 would be used.

NOTE: The value entered into the control will be the CO ppm level divided by 10. For example 100 ppm would be entered as 10.

6. Determine the upper control point differential level (DAQHI) and enter it into the control. This is a differential level so if the desired leve l to star t IAQ co ntrol is 1100 ppm and the OAQ reference level is 400 then a value of 700 would be used.

NOTE: The value entered into the control will be the CO ppm level divided by 10. For example 700 ppm would be entered as 70.

D. Power Exhaust Configuration

The EconoMi$er+ can control up to 2 stages of power exhaust. Power exhaust activation is done through configurable damper pos ition set points. The first stage of power is controlled by relay C4 on the EconoMi$er+ board. The activation point for the first stage is set using the Power Exhaust Stage 1 Activation set point (PE_SP1 ). The second stage of powe r exhaust mus t be set at a v alue greater than the first stage. It is configured using the Power Exhaust Stage 2 Activation set point (PE_SP2).

XVIII. OPERATING SEQUENCE

A. Cooling, Units Without EconoMi$er+

When thermostat calls for cooling, terminals G and Y1 and the compressor contactor (C) are energized. The indoor (evaporator) fan motor (IFM), compressor, and outdoor (condenser) fan motor (OFM) start. The OFM runs continuously while the unit is in cooling. When the thermostat is satisfied, C is deenergized and the compressor and OFM shut off. After a 30-second delay, the (IFM) shuts off. If the thermostat fan selector switch is in the ON position, the evaporator motor will run continuously.

B. Heating, Units Without EconoMi$er+

When the thermostat call s for heatin g, terminal W1 is energized. The induced-draft motor is energized and the burner ignition seque nce begins. The indoor (evaporator) fan m otor (IFM) is energized 45 seconds after a flame is ignited. When additional he at is n eeded, W 2 is en ergized and t he high- fire solenoid on the main gas valve (MGV) is energized. When the thermostat is sati sfied and W1 is deenergiz ed, the IFM stops after a 45-second time-off delay.

C. Cooling, Units With EconoMi$er+

For EconoMi$er+ operation, there must be a thermostat call for the fan (G). This will move the damper to its minimum position.

When the EconoMi$er+ control is the occupied m ode and a call for cooling exists (Y1 on the thermostat), the control will first check for indoor fan operat ion. If the fan is not on, th en cooling will not be activated. If the fan is on, then the control will open the EconoMi$er+ damper to the minimum position.

On the initial p ower to the EconoMi$er+ board, it will ta ke the damper up to 2

/2 minutes before it begins to position itself. With subsequent fan signal (G) to the board, the change in damper position will take up to 30 seconds to initiate. Damper movement from full closed to full open (or vice versa) will take 2

/2 minutes.

If the damper is in the process of a change (for example going to 100% open) and the signal (G) is turn ed off, the damper will continue to open to 100% before it closes (due to no fan signal [G]).

If free cooling c an be used as determin ed from the appr opriate changeover command (switch, dry b ulb, enthalpy curv e, differential dry bulb, or differential enthalpy), then the control will modulate the dampers open to main the supply air temperature set point plus 2° F.

If there is a further demand for cooli ng (coo li ng secon d st age — Y2 is energized), then the control set point for the l eaving air will be set at the supply air set point to increase the cooling capacity. If this cannot satisfy the load then the control will bring on comp ressor stages as needed to maintain the supply air temperatu re set point. The EconoM i$er+ damper will be locked o pen at 100% or the maximu m damper position set point.

To ensure that there is oil return, the compressors will operate for at least 3 minutes. If, during this period, the leaving temperature drops below the set point by 5° F, then the EconoMi$er+ dampers will be closed to 60% until the compressor is turned off to avoid cold leaving air temperatures.

If the conditions are not suitable for free cooling then the EconoMi$er+ dampers will be closed to the minimum ventilation posit ion.

Compressor stage s will be used to co ol the air. If the control is configured for direct control by Y1 and Y2, then the stages will sequence based on the demand of Y1 and Y2. If the control is configured for leaving air temperature control, then Y1 will maintain the leaving air temperature at the supply air set point plus 2° F. If Y1 and Y2 are closed, then the leaving air will be c ontrolled t o the supp ly air se t point. If Y2 is closed and Y1 is open, then control will shut down and indicate an error due to a thermostat failure or improper wiring of the thermostat.

If the unit is in the unoccupied m ode, then the control of the temperature will depend on the unoccupied free cooling configuration: no unoccupied cooling, unoccupied free cooling with any mechanical cooling, or unoccupied free and mechanical cooling. If free cooling is enabled, then the control will check if free cooling can be used. The EconoMi$er+ will then control to the leaving air temperature set point plus 2° F for a Y1 command, or the leaving air temperature set point for a Y1 and Y2 command. If me chanical coo ling is allowed to be used, then the control will then bring on additional stages o f me chani cal coo lin g i f f ree co ol in g c annot sa tisfy the load.

If the EconoMi$er+ control:

• is in the occupied mo de

• is configured to use demand ventilation

• cannot use free cooling

• has return air or space CO

levels below the DAQLO

limit,

then the EconoMi$er+ damper position will be set to the IAQMIN_SP set point. If the CO2 level rises above the DAQLO limit, then the dampers will modulate open in a linear relationship un til the return air o r space CO

levels are

at or above th e D AQHI l imit . The da mpe r p o siti on w il l be at the ECONOMIN_SP set point.

When the EconoMi$er+ is being used for free cooling and the position exceeds the power ex haust set point, then the control will turn on the appropriate power exhaust fans. Refer to Fig. 23 for barometric relief capacit y, Fig. 24 for outdoor air leakage, and Fig. 25 for pressure drop.

Unoccupied and Occupied Minimum Position Control There is an unoccupied minimum damper position and an

occupied minimum damper position on the EconoMi$er+ controller. When the HVAC fan is off the outdoor air damper will always be closed. W hen the f an is on an d in the unoccu pied mode, the outdoor air damper will be at the unoccupied minimum position . When the fan is on (G call ) and in the occupied mode, the outdoor air damper will be at the occupied minimum position.

A jumper wire is factory-installed to force the unit into o ccupied configurat io n wh ene ver G or Y1 are clos ed. Withou t the jumper wire, the unit will always be in unoccupied mode.

The 2 minimum position settings are also used in the IAQ sequence of operation. See Indoor Air Quality Sensor on page 21.

NOTE: The minimum position signal takes priority over the maximum position sign al. If th e maxi mum da mper positi on is set below the minimum damper position, the EconoMi$er+ controller will maintain the actuator at minimum position.

—60—

Page 61

Adjust the unoccupied minimum position to allow the minimum amount of outdoor air, as required by local codes, to enter the building. Make minimum position adjustments with at least 10 F (6 C) temperature difference b etween the outdoor and return air temperatur es.

To determine the unoccupied minimum position setting, perform the following procedure:

Calculate the appr opriate supply-ai r temperature using the following formula: (TO x OA) + (TR x RA) = TM

TO = Outdoor-Air Temperature OA = Percent of Outdoor Air TR = Return-Air Temperature RA = Percent of Return Air TM = Supply-Air Temperature

As an example, if local codes requ ire 10% outdoor air duri ng occupied conditions, outdoor-air temperature is 60 F, and return-air temperature is 75 F:

(60 x 0.10) + (75 x 0.90) = 73.5 F

Carefully adjust the unoccupied minimum position until the measured supply-air temperature matches the calculated value. Then, carefully adjust the occupied minimum position set point on the controller until the desired position is reached.

D. Heating, Units With Economizer+

When the thermostat call s for heatin g, terminal W1 is energized. The induced-draft motor is energized and the burner ignition seque nce begins. The indoor (evaporator) f an motor (IFM) is energized 45 seconds after a flame is ignited. When additional he at is n eeded, W 2 is en ergized and t he high- fire solenoid on the main gas valve (MGV) is energized. When the thermostat is satisfied and W1 is deenergized, the IFM stops after a 45-second time-off delay. The economizer damper moves to the minimum position. When the thermostat is satisfied, the damper moves to the fully closed position.
