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 service air-conditioning equipment.

Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other operations sh o uld be perfor me d by trai ne d se rvi ce personnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that apply.

Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for unbrazing operations. Have fire extinguishers available for all brazing opera tions.

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 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.

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

CAUTION: Ensure voltage listed on unit data plate agrees with electrical supply p r ov ided fo r t he unit .

Unit is ship ped in t he ve rti cal d uc t con figu rat ion . To convert t o 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 accessory roof curb in accordance with instructions shipped with curb. See Fig. 3. Install insulation, cant strips, roofing felt, and counter flashing as shown. Duct-

work must be attached to curb, not to the unit. The accessory thru-the-bottom power and gas connection package must be installed before the unit is set on the roof curb. If field-

installed (thru-the-roof curb) gas connections are desired, use factory-supplied to mount the thru-the-roof curb connection to the roof curb. Gas connections and power connections to the unit must be field installed after the unit is installed on the roo f curb.

If electric and control wiring is to be routed through the basepan, attach the accessory thru-the-bottom service connections to the basepan in accordance with the accessory installation instructions.

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 result in air 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.

B. Slab Mount (Horizontal Units Only)

Provide a level concrete slab tha t extends a minimum of 6 in. beyond unit cabi ne t. I nsta ll a grav el apr on in f ron t of con dens er coil air inlet to prevent grass and foliage from obstructing airflow.

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

C. Alternate Unit Support

A non-combustible sleepe r rail can be used in the unit curb support area. If sleeper rails cannot be used, support the long sides of the unit with a minimum of 3 equally spaced 4-in. x 4-in. pads on each side.

II. STEP 2 — FIELD FABRICATE DUCTWORK

Secure all ducts to roof curb and building s tructure on verti cal ducted units. Do not connect ductwork to unit. For h or izontal applications, fiel d-supplie d flanges sh ould b e attach ed to horizontal duct openings and all ductwork should be secured to the flanges. Insulate and weatherproof all external ductwork, joints , and roo f 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 –.20 in. wg with economizer or –.45 in. wg without economizer.

These units are designed for a minimum continuous heating return-air temperature of 50 F (dry bulb), or 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 when these lower air temperatures are used with insufficient heating temperature rise.

III. STEP 3 — INSTALL EXTERNAL TRAP FOR CONDENSATE DRAIN

The unit’s

/4-in. condensate drain connections are located on the bottom and side of the unit. Unit discharge connections do not determine the use of drain connections; eit her 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-i nstalle d plug (Re d) from t he bott om connection to the side connection. The center dr ain plug l ooks like a star connection, however it can be removed with a

/2-in. socket drive. 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 at least 4-in. deep and protect against freeze-up. If drain line is installed downstream from the external trap, pitch the li ne away fr om th e unit a t 1 i n. per 10 ft of run . Do not use a pipe size smaller than the unit connection (

/4 in.).

See Fig. 5B.

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 ref erence. See Table 1 and Fi g. 6 for additional information.

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

CAUTION: All panels must be in place when rigging.

A. Positioning

Maintain clearan ce around and above un it to provide minimum distance from combustible materials, proper airflow, and service access. See Fig. 1A a nd 1B. A properly positioned unit will have the follo wing c l ea ranc es betw een unit a nd r oof

curb:

/4-in. clearance between roof curb and base rails on each side and duct end of unit; 1/4-in. clearance between roof curb and condenser coil end of unit. (S ee Fig. 3, section C-C.)

Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contaminated air.

Be sure that unit is installed such that snow will not block the combustion intake or flue outlet.

Unit may be installed dire ctly on wood flooring or on Class A, B, or C roof-covering material when roo f curb is used.

Although unit is weatherproof, guard against water from higher level runoff and overhangs.

Flue vent discharge must have a minimum horizontal clearance of 4 ft from electric and gas meters, gas regulators, and gas relief equipment.

Minimum distance between unit and other electrically live parts is 48 inches.

Flue gas can deteriorate building materials . Orie nt unit suc h that flue gas will not affect building materials.

Adequate combustion-air space must be provided for proper operation of this equipment. Be sure that installation complies with all local codes and Section 5.3, Air for Combustion and Ventilation, NFGC (National Fuel Gas Code), and ANSI (American National Standards Institute) Z223.1, and NFPA (National Fire Protectio n Association) 54 TIA-54-84-1. In Canada, installation must be in accordance with the CAN1-B149 installation codes for gas burning appliances.

After unit is in position, remove rigging skids and shipping materials.

V. STEP 5 — INSTALL FLUE HOOD

Flue hood is shipped screwed to the basepan beside 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 equipped for use wi th type of gas shown on nameplate. Refer to local building codes, or in the absence of local codes, to ANSI Z223.1 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.

For natural gas applications, gas pressure at unit gas connection must not be less than 4 in. wg or greater than

13.0 in. wg while unit is oper atin g. On 580F04 8,0 60,072 high heat units, the gas pressure at unit gas connection must not be less than 5 in. wg or greater than 13 in. wg while the unit is operating. For propane applications, the gas pressure must not be less than 5 in. wg or greater than 13 in. wg at the unit connection.

Size gas supply piping for 0.5 in. wg maximum pressure drop. Do not use supply pipe smaller than unit gas connection. Support gas pipi ng as shown in the ta ble in Fig. 8. For example, a

/4-in. gas pipe must have one field-fabricated support beam every 8 ft. Therefore, an 18-ft long gas pipe would have a minimum of 2 support beams, a 48-ft long pipe would have a minimum of 6 support beams.

See Fig. 8 for typical pipe guide and locations of external manual main shutoff valve.

CAUTION: When connecting the gas line to the unit gas valve, the installer MUST use a backup wrench to prevent valve damage.

/4-in. male terminal on the primary side of the

transformer. Refer to unit label diagram for additional information.

Pigtails are provided for fie ld wire connectio ns. Use factorysupplied splices or UL (Underwriters’ Laboratories) approved copper/aluminum connector.

When installing units, provide a disconnect per the NEC. All field wiring must comply with NEC and local require-

ments. Install field wiring as foll ows:

1. Install conduit through side panel openings. Install conduit between disconnect and control box.

2. Install power lines to terminal connections as shown in Fig. 9.

Voltage to compressor terminals during operation must be within voltage range indicated on unit nameplate (see Tables 2A and 2B). On 3-phase units, voltages between phases must be balanced within 2% and the current within 10%. Use the formula shown in the legend for Tables 2A and 2B, Note 2 to determine the percent of voltage imbalance. Operation on impr op er lin e volta ge or excess ive phase imbalance constitutes abuse and may cause damage to electrical components. Such operation would invalidate any applicable Bryant warranty.

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. Connect thermostat wires to terminal board.

Route thermostat cable or equivalent single leads of colored wire from subbase terminals through connector on unit to low-voltage connections (shown in Fig. 10).

NOTE: For wire runs up 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

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.

3. For units with power exhaust: If a single power source is to be used, size wire to include power exhaust MCA and MOCP. Check MCA and MOCP when power exhaust is powered through the unit (must be in accordance with NEC and/or local codes). 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 580F060 unit with MCA = 28.9 and MOCP = 35, with

CRPWREXH030A00 power exhaust. MCA New = 28.9 amps + 1.6 amps = 30.5 amps If the new MCA does not exceed the published MOCP, then MOCP would not change. The

MOCP in this example is 35 amps, the MCA New is below 35, 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. R efer 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 minim um position. If the outdoor air tem perature is below the set point, the position should be controlled to maintain the leaving air temperature set point. The set point 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 supports outside air enthalpy changeover 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 for details on how to configure and enable the contro l mode. The user can check the o peration of the sensors using the Read function.

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

trol. This requir es the factory -supplied ou tside air tempera ture sensor, an accessory outdoor air humidity sensor, an accessory return air temperature sensor, and an accessory indoor air humidi ty 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 economizer position. Refer to the setup examples on page 42.

E. EconoMi$er+ Controller Wiring

The EconoMi$er+ is sup plied fr om the factory with a supply air temperature sensor and an outside air temperature sensor. This allows for op eration of the EconoMi$e r+ with outside 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$er+ co ntrol works with conventional t hermostats that have a Y1 (cool stage 1), Y2 (cool stage 2), W1 (heat stage 1), W2 (heat stage 2), and G (fan). The EconoMi$er+ control does not support sensor thermostats like the T56 and T57. Connections are made at the thermostat terminal connection board located in the main control box.

I. Indoor Air Quality (IAQ) Sensor

Any indoor air quality or CO 20 mA output can be used as the IAQ sensor. The controller will modulate the o utdoor-air damper to pr ovide ventilati on based on the sensor output and the IAQ setting of the controller . The CO from the minimum po sition ( IAQ minimum damper po sition set point) to the maximum position (occupied minimum damper positi on). When th ere i s no CO go to the unoccupied minimum position. When there is a CO call, the damper will be between the IAQ minimum economizer set point position and the occupied minimum damper position.

Mount the sensor according to manufacturer specifications. In order to wire this sensor, an accessory 5-pin plug (part number CRE+PLUG001A00) is required. See Fig. 22.

The IAQ sensor is wired to the g round a nd IAQ w ires in the harness. The a ccesso r y 5-pin wi ring plug is c onnec ted to pi ns 13-17 of J3 on the EconoMi$er+ controller. Push the plug

The sensor is factory-installed on the EconoMi$er+ in the outdoor airstream. The operating range of temperature measurement is 0° to 158 F. See Tables 5 and 6 for thermistor resistance and resolution values.

The temperature sensor l ooks like an eyelet terminal with wires running to it. The sensor is located in the “crimp end” and is sealed from moisture.

The user can read the value of the sensor using the Read mode, described in the Start-Up section.

H. Supply Air Temperature (SAT) Sensor (Provided)

The supply air temperature sensor is a 10K thermistor located at the inlet to the indoor fan. This sensor must be field installed . Th e o per ating range of temperature me as ur ement is 0° to 158 F. See Tables 5 and 6 for thermistor resistance and resolution values.

The temperature sensor l ooks like an eyelet terminal with wires running to it. The sensor is located in the “crimp end” and is sealed from moisture.

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

Pins 13 and 14 are used for the IAQ sensor. Pins 15-17 are used for the field-installed remote potentiometer. Connect the IAQ sensor to the BRN and WHT wires o f the accessor y 5-pin plug.

NOTE: Pin numbers are not shown on the controller. They are provided only as reference for the installer. On the EconoMi$er+ board, they numbered 1-17 from left to right, but only the 1 and the 17 are printed on the board.

Sensor wiring should be extended with wire and wire nuts and routed to the IAQ sensor location. Adjust the IAQ setting at the controller to correspond to the IAQ voltage output of the sensor at the user-determined set point. See Fig. 26. Power the sensor with a field-supplied transformer.

J. Return Air Temperature (RAT) Sensor

The EconoMi$er+ controller will accept input from the accessory 10K return air temperature sensor (CRTEMPSN001A00) in addition to the outdoor air temperature sensor shipped with the EconoMi$er+. By using both sensors, the outdoor air and the return air temp eratures are compared (differential dry bulb) for optimal energy savings. See Tables 5 and 6 for thermistor resistance and resolution values.

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

Mount the return air temperature sensor on the EconoMi$er+, through pre-punched holes. See Fig. 27.

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$er+ controller to the sensor. The controller compares the temperatures of the two airstreams, chooses the best one, and modulates the EconoMi$er+ actuator accordingly.

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

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. The controller selects the lower enthalpy ai r (return or outdoor) for cooling. For example, when the outdoor air has a lower enthalpy than the return air, the EconoMi$er+ controller opens the damper to bring in outdoor air for free cooling.

Mount the return-air humidity sensor in the return-air duct. See Fig. 31.

The outdoor enthalpy changeover curve is set with at the EconoMi$er+ controller. The selectable curves are A, B, C, and D. The factory default is curve “A.” See Fig. 29. See Fig. 30 for Sensor Curve vs. Humidity.

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 occupied mode and when open, there is no signal to indicate unoccupied mode. The control can be configured to allow different minimum economizer damper positio ns and to control how mechanic al cooling will and will not be used in the occupied mode.

NOTE: The remote potentiometer (see below) will override the occupied minimum position if the potentiometer s etting is greater than the occupied minimum position.

A wire from J1-OCC (pin 4) and a wire from J1-24V (pin 5) are wire-nutted together to jumper the terminals.

An occupied/unoccupied switch can be field-installed in place of the jumper to allow the user to force the control into occupied or unoccup ied 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+ d a mp e r vent positions in th e u noc c up ie d m od e.

N. Power Exhaust

Refer to the Accessor y Power Exhaust i nstallation instructions for information on installing the power exhaust accessory.

O. Remote EconoMi$er+ Enable Control

When the control is used with energy ma nagement syst ems that enable and disable the EconoMi$er+, the user can install a field-supplied 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 th e control.

P. R e mote Potentiometer Occupied Minimum Position

The occupied minimum position set point remote potentiometer (field-sup plied) is used when requ iring 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 from the harness is connected to pin 16 (MIN). The yellow wire from the harness 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 minimum position can only be set at the controller. The occupied minimum position set point configured at the EconoMi$er+ controller shou ld 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+ control ler unoccupie d 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$er+ damper is established based on the demand occupancy of the space. The IAQ sensor will be used to modulate the EconoMi$er + minimum damper position below the normal minimum position based on full occupancy. The lower limit is called the base ventilat ion r ate . S ee 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

—22—

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 esta blish the base ventilation rate (IAQMIN_SP) and the design 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 lo wer I AQ differ ential set point is DAQLO.

The differential set points represent the differential CO level (in ppm) above the outdoor reference IAQ levels. Normally, the outdoor reference IAQ levels are around 400 ppm, bu t the value should be configured bas ed on the reference levels taken at the job site.

The following equation is used to determine EconoMi$er+ damper position (ECONOMIN_POS):

IAQMIN_SP +=

R. CO

(ECONOMIN_SP – IAQMIN_SP) * (IAQ – OAQ – DAQLO)

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 sens or. 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 warnings

could result in serious personal injury .

1. Follow recognized safety practices and wear protective goggles when checking or the servicing refrigerant system.

2. Do not opera te the compres sor or provide an y electric power to the unit unless the compres sor termina l cover is in place and secured.

3. Do not remove the com pre ssor termi nal cover unti l all electrical sources are disconn ected.

4. Relieve all pressure from the system before touching or disturbing anything in side the c omp ress or term ina l box if refrigerant leak is suspected around the compressor terminals.

5. Never attempt to repai r a soldered connection while the refrigerant system is under pressure.

6. Do not use torch to remove any component. The system contains oil and refrigerant under pressure. To remove a component, wear protective goggles and proceed as follows: a. Shut off gas and then electrical power to the unit.

Install lockout tag.

b. Relieve all pressure from the system using both

high-pressure and low-pressure ports.

c. Cut the component connection tubing with a tubing

cutter, and remove the component from the unit.

d. Carefully unsweat the 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, the unit.

3. Make the following inspections: a. Inspect for shipping and handling damages such

as broken lines, loose p arts, or discon nec ted wires, etc.

b. Inspect for oil at all refrigerant tubing connections

and on unit base. Detecting oil generally indicates a refrigerant leak. Leak-test all refrigerant tubing connections using an electronic leak detector, halide torch, or liquid-soap solution.

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

Be sure that connections are completed and tight.

d. Inspect coil fins. If damaged during shipping and

handling, carefully straighten the fins with a fin comb.

4. Verify the following conditions: a. Make sure that condenser fan blade is correctly

positioned in the fan orifice. See Condenser-Fan

Adjustment section on page 48 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 bee n installed in accordance with these installation instructions and applicable codes. Make

sure Start-Up Checklist on back page is filled out and completed.

II. RETURN-AIR FILTERS

Make sure correct filters are installed in filter tracks. See Table 1. Do not operate unit without return-air filters.

III. COMPRESSOR MOUNTING

Compressors are internally spring mounted. Do not loosen or remove compressor holddown bolts.

IV INTERNAL WIRING

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

V. GAS PIPING

Check gas piping for leaks.

WARNING: Disconnect gas piping from unit when

leak testing at pressure greater than

sures greater tha n

/2 psig will cause g as valve damage

/2 psig. Pres-

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 the gas valve.

VI. REFRIGERANT SERVICE PORTS

To service refrigerant service ports, remove compressor access panel. Each unit system has 4 Schrader-type service gage ports: one on the suction line, one on the liquid line, and two on the compressor discharge line. Be sure that caps on the ports are tight. One of the Schrader-type valves on the compressor discharge line is located under the low-pressure switch.

The Schrader valve on the compr essor di scharge li ne that is located under the high pressure switch does not contain a Schrader core in the valve.

VII. 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- r in gs located inside the c aps. These valv es cannot be accessed for service in the field. Ensure the plastic caps are in place and tight or the possibility of refrigerant leakage could occur.

VIII. 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 gage s 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.

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 tag disconnect.

3. Reverse any two of the unit power leads.

4. Reapply power to the unit.

—37—

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

NOTE: When the compres sor is rotating in the wrong direction, the unit makes an elevated level of noise and does not provide cooling.

IX. COOLING

Set space thermostat to OFF position. To start unit, turn on main power supply. Set system selector switch at COO L position and fan switch at AUTO. position. Adjust thermostat to a setting below room temperature. Compressor, outdoor fan and evaporator motor start on closure of contactor.

Check unit charge. Refer to Service, Refrigerant Charge section, page 48.

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

To Shut Off Unit

Set system selector switch at OFF position. Resetting thermostat at a position ab ove room temperature shu ts unit off temporarily until space temperature exceeds thermostat setting.

X. 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 abov e room tem perature a nd verify that the burners light and evaporator fan is energized. After ensuring that the unit continues to heat the building, lower the thermostat setting below room temperature and verify that the burners and evaporator fan turn off. (Fan will turn off only if fan selector switch is in the AUTO. position.)

Refer to Table 34A and 34B for the correct orifice to use at high altitudes.

XI. HEATING

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

2. Turn on electrical supply and manual gas val ve .

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.

5. After a call for heating, the main burners should light within 5 seconds. If the burner does not light, then there is a 22-second delay before another 5-second try. If the burner still does not light, the time delay is repeated. If the burner does 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 wil l turn on 45 seconds after the burners are ignited.

7. The evaporator-fan motor will turn off 45 seconds after thermo st a t te m p e r at u r e i s sa t isfied.

8. Adjust airflow to obtain a temperature rise within the range specified on the unit nameplate.

NOTE: The default value for the evaporator-fan motor ON/ OFF delay is 45 seconds. The Integrated Gas Unit Controller (IGC) modifies this value when abnormal limit switch cycles occur . Based upon unit operating conditions, the ON delay can be reduced to 0 seconds and the OFF delay can be extended

to 180 seconds. When one flash of the LED is observed, t he evaporator-fan ON/OFF delay has been modified.

If the limit switch trips at the start of the heating cycle during the evap or ator ON delay, t he time period of the ON delay for the next cycle will be 5 seconds less than the time at which the swit ch trip ped. (Exa mple: If th e l imit switch trip s at 30 seconds, t he ev aporator-fan ON delay for the next cycle will occur at 25 seconds.) To prevent short-cycling, a 5-second reduction will only occur if a minimum of 10 minutes has elapsed since the last call for heating.

The evaporator-fan OFF delay can also be modified. Once the call for heating has ended, there is a 10-minute period during which the modification can occur. If the limit switch trips during this period, the evaporator-fan OFF delay will increase by 15 seconds. 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.

To Shut Off Unit

Set system selector switch at OFF position. Resetting heating selector lever bel ow room temperature will temporar ily shut unit off until space temperature falls below thermostat setting.

XII. SAFETY RELIEF

A soft solder joint at the suction service Schrader port provides pressure relief under abnormal temperature and pressure conditions (i.e., fire in building).

XIII. 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.

XIV. 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$er+ controller is protected by a sheet metal enclosure mounted over the controller. Remove the single screw on the front of the enclosure and lift off the top for access to the controller . The primary purpose of the controller is to provide control of the EconoMi$er+ dampers and the cooling compression stages. The status of the indoor fan is monitored through the G input but is not directly controlled 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 electron ic thermostats wi th a proportional room temperature input, or with Variable Air Volume systems.

There are 4 LEDs on the con troller, which are used to rea d 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 co ntrol See Table 35 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 con figure

the control.

B. Startup Mode

During the first 3 seconds after power is applied to the control, the four LEDs flash as shown in Table 36, 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 economiz e r is b ein g us ed f or f re e cool i ng. 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 37) and I/O channel status (Table 38). 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 tens digit and the DS4 LED will the n 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 read the display again, push the READ/ADJUST (#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 cycl e through all the setup channels (Table 37) and then the I/O channels (Table 38) and then back to the first setup channel.

NOTE: The user can only advance forward, not reset to #1 or go backwards. Cycling the EconoMi$er + po we r will r eset 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.

—41—

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 38. 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 greater than 4 the controller will count out the increments of 5 a t a high fl ash rate foll owed by the remaining digits. The channel number will be counted out through the DS2 LED (yellow). Th e status value wil l 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 D S3 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 37 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 Setup mode, all routines including safety routines will continue to run and control the unit.

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 c omes on, and agai n when th e 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.

—42—

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%, which is higher than the 2% value in this example.)

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

NOTE: Before performing Step 8, be ready to push button #1; there is a limited time window that can ea sily be missed when the DS3 green LED com es on, and ag ain wh en the DS 4 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 and 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 S tep 13, be ready to push button #1; there is a limited time window that can ea sily be missed when the DS3 green LED com es on, and ag ain wh en the DS 4 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 and 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 Table 37) are dependent upo n other items. Befo re 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 38.

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 Manual mode from the RUN mode, which is entered by pushing buttons #1 and #2 for at least 3 seconds.

All EconoMi$er+ control outputs are turned 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 c han nel . Se e Table 38. If th e val u e is le ss th an 5, the yellow DS2 LED will count out the valu e using 1-secon d 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 exiting the Manual mode, the controller will re-initialize 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 recen t err or”). De termi ne the error by reading the value in items 20 to 24 and referring to the Troubleshooting section.

One the error has been fixed, press 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.

XV. ECONOMI$ER+ CONFIGURATION

For most applications, the factory setting will be used to control the EconoMi$er+. However, there are 19 diff erent variables that can be used to co nfig ure the contr ol for wide r an g e of applications. The factory settings and variable s are shown in Table 37.

—43—

IMPORTANT: There is no way to reset/restore the factory default c onfig urati ons; us e ca utio n when makin g chang es to any set point or operational variabl e.

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 37 items 2 (ECONOMIN_SP) and 3 (U_ECONOMIN_SP). These va lues represent the minimu m damper position. In addition, the controls allows for different modes of compressor operation in the unoccupied mode. Using item 13 in Table 37 (OCC_MODE), the user can select one of the following unoccupied modes:

• No unoccupied cooling

• Unoccupied free cooling (Econ oMi$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 unoccupied mode. Depen ding on the configuration, the control will move the outside air damper to the ventilati on position. If the outside air co nditions are acceptable, then the control will use the EconoMi$er+ for free cool ing. If the supply air temperature 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 from 1 to 4 compressor stages. For the 3 to 12

/2 ton units, there will only be 1 or 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 37. 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 te mperatur e using Y1 and Y2 as a low cool and high cool demand based on the supply air set point and the rate of ch ange of supply air tem perature. For low cool the leaving air temperature set point will be SAT_SP+2° F. For high cool the leaving air temperature 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 set 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 logic includes time guards on the compressors to provide a minimum of 3 minutes on and 3 minutes off time. The control will also prevent two compressors from starting at the same time. The lo gic use s the EconoMi $er+ to prev ent 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 37. 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 t o the approp riate occupied and unoccupied 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 2 F higher.

Minimum Damp er Position Set the occupied minimum damper position

(ECONOMIN_SP) and unoccupied minimum position (U_ECONOMIN_SP). These should be set to provide 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 measured CO

levels in the space 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:

OA =

SAT – RAT OAT – RAT

*100

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 differen ce between the OAT and RAT temperatures.

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).

—44—

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$er+ w ill be enabled based on the outsid e -air temperature. The EconoMi$er+ is shipped with an outside air tempe rature sensor. The outside 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 select the differential dry b ulb function.

4. Outdoor Enthalpy — For this changeover setting, the control will enable the EconoMi$er+ based on the outside-air enthalpy curves as shown in Fig. 29. Using the EconoMi$er+ Changeover set point (ENTHALPY_SP), select curves A, B, C or D. The control will then us e 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+ p osition that brings in enough fresh ai r to remove conta minants and CO generated by sources other than people. The ECONOMIN_SP should be set to an EconoMi$er+ positi on that brings in enough fresh air to remove contaminants and

generated by all sources including people a t 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_FLG).

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

NOTE: The value entered into the co ntrol 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 co ntrol 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 co ntrol will be the CO

ppm level divided by 10. For example 700 ppm

would be entered as 70.

D. Power Exhaust Configuration

The EconoMi$er+ can control up to 2 stages of power exhaust. Power exhaust activation is done through configurable damper pos ition set points. The first s tage of power is controlled by relay C4 on the EconoMi$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).

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

—45—

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 changed 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 a t least 3 mi nutes. If, dur ing th is pe riod , th e lea ving temperature dr ops 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 stages 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 controlled to the supply air set 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 unoccupie d cool ing, 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 mode

• 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 the DAQ HIG H limi t. The dampe r posit ion wi ll be at the ECONOMIN_SP set point.

When the EconoMi$er+ is being used for free cool ing and the position exceeds the power exhaust 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 occupied configuration whenever G or Y1 are closed. Without the jumper wire, the unit will alw a ys be in unoccupi ed mode.

The 2 minimum position settings are also used in the IAQ sequence of operation. See Indoor Air Quality Sensor on page 18.

NOTE: The minimum pos ition signal tak es priority over the maximum position signal. If the maximum damper position is set below the min imu m damper position, the Econ oMi $e r+ controller will maintain the actuator at minimum position.

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 between the outdoor and return air temperatu res.

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

Calculate the app ropriate supply-ai r temperature usin g the following formula: (T O x OA) + (T R 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

—46—

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 Economi$er+

When the room temperature calls for heat through terminal W1, the indoor (evaporator) fan contactor (IFC) and heater contactor no. 1 (HC1) are energized. On units equipped for 2 stages of heat, when additional heat is needed, W2 is energized and the hig h-fire sole noid o n the main gas v alve (MG V) is energized. The economizer damper moves to the minimum position. When the thermostat is satisfied, the damper moves to the fully closed position.
