1. INSTALLATION

Horizontal/Vertical Economizers

1. Attach mixing box to unit evaporator return,

using the metal securing strip provided.

Fasteners may also be used around the

perimeter of the mixing box, at the location of

the filter frame, for additional security. This is

intended to connect the units, and not to support

the full weight of the economizer mixing box –

ADDITIONAL FIELD SUPPORT IS REQUIRED.

This may be from the ceiling, or from beneath

the unit.

2. Determine which inlet will be outside air, and

which will be return air. If the normal

open/closed position of the dampers needs to be

reversed, remove the actuator, reset the damper

positions so that the outside air damper is

closed and the return air damper is fully open.

Adjust the linkage rod to these normal positions,

and secure. Reattach the actuator so that it is

rotating in the appropriate direction.

3. The module is connected to the unit wiring via a

2-part molex wiring harness. Minimal field

rewiring of the unit is required in order to

accommodate the Air-Side Economizer option.

Refer to Section 6 for detailed instructions.

Connect the wiring harness to the

microprocessor board as indicated in Section 4

– Wiring Harness Installation.

4. With the power to the module, the actuator

springs will wind and lock. The enthalpy

changeover setting may be altered, and the

outside air damper minimum position adjusted.

See the attached Honeywell JADE – W7220

Economizer Controller Manual for details.

NOTE: Jade will be in the "set up" mode for the

first 60 minutes after powered. If a sensor for

Outdoor Air (OA) is disconnected during the set

up mode, the Jade will not alarm that failure. The

Mixed Air (MA) sensor is a system "critical"

sensor, if the MA sensor is removed during the

set up mode, the Jade will alarm. After 60

minutes the Jade controller will change to

operation mode and all components removed or

failed will alarm in the operation mode.

Prior to installing or servicing the

unit, lock all electrical power supply

switches in the OFF position. Failure

to disconnect power supply may

result in electrical shock or even

death.

Additional field support of the mixing

box is required. Failure to provide

adequate support for the unit may

result in injury or even death.

Exercise care when working around

the sharp metal edges of door panels

or flanges. These edges are sharp

and can cause injury.

4. WIRING HARNESS INSTALLATION -

AIRSIDE ECONOMIZER TO UNIT

CONNECTION

Each Air-Side Economizer is shipped complete with

a two-part wiring harness. The terminated end of the

wiring harness that is shipped in a package with the

economizer must be field wired into microprocessor

board. The second part of the harness assembly is

pre-wired into the Economizer module panel. The

two parts of the harness are connected together by

integrated polarized molex plugs.

For split unit applications (horizontal units only)

the harness will need to be extended in the field

using 18 gauge wire.

Locate the Mixed Air sensor (C7250A1001) inside

supply discharge duct. Wire other end into the MAT

terminals of the W7220 module.

Locate the Outdoor Air Temp/Humidity Sensor

(C7400S1000) in the outdoor air duct. This will be

wired into the S-BUS terminals of W7220 module.

and that there are no loose wires that can be

pulled into the blower inlet. Coil excess wire

length, and secure with cable clips (see photo).

5) The plug end of the harness should terminate

inside the rear corner post. The economizer half

of the harness will enter through the knockout

hole in this area. Ensure the harness is secured

on the outside of the unit using the cable clips

provided.

Installing Harness (Horizontal Units):

1) Working from the evaporator blower access

door, feed the loose pre-terminated ends of the

harness along the base of the unit towards the

right end and back out, using the low voltage

electrical conduit, to the condenser section and

into the condenser electrical panel. For split

unit applications the harness will need to be

extended in the field using 18 gauge wire.

Ensure the cable is protected from damage and

the wiring meets all local code requirements.

2) Inside the condenser electrical box, connect the

harness terminations to the microprocessor

board economizer harness terminations (Y-Out,

G-Out, ECON, and OCCUPIED), as shown in

the electrical schematic. Note the Occupied

terminal is not being used in the standard factory

setup and has been provided if required in the

field.

3) Connect the WHITE COMMON wire from the

harness onto the Common tab on the

microprocessor board, using the provided tab

adapter, as shown in the electrical schematic.

4) Inside the blower section of the evaporator unit

secure the harness along base towards the left

corner post using the supplied cable clips.

Ensure that the harness is routed clear of

moving parts and sharp edges, and that there

are no loose wires that can be pulled into the

blower inlet. Coil excess wire length, and secure

with cable clips (see photo).

5) The plug end of the harness should terminate

inside the bottom left corner post. The

economizer half of the harness will enter through

the knockout hole in this area. Use a punch out

tool or screwdriver. Feed the plug end harness

through and connect to the other half of the

economizer harness. Ensure the harness is

secured on the outside of the unit using the

cable clips provided.

6. SEQUENCE OF OPERATION

NOTE: Refer to the ‘Honeywell JADE (W7220)

ECONOMIZER MODULE’ manual accompanied

with this kit for additional information regarding

additional sensors, enthalpy settings and alarms

Modulating Economizer with Typical Electro -

Mechanical Thermostat

The Honeywell W7220 module, ML series actuators,

JCI damper sections, and factory wiring harness

comprise an integrated economizer. These

economizers are used to provide ventilation and free

cooling for the JCI Series of vertical and horizontal

air handlers.

The Honeywell W7220 can accept inputs from

additional optional sensors (field provided), including

a return-air enthalpy sensor (for differential enthalpy

control) or a CO

sensor for Indoor Air quality

strategies.

The economizer module setup is done through the

LCD keypad display. For more information regarding

setup and other features, consult the Honeywell

JADE - W7220 Economizer Controller Manual

included with the Economizer kit.

Powering the Thermostat (24vac) -

Power to the electromechanical thermostat is

provided from R terminal of the JCI unit’s low voltage

terminal strip. Electromechanical thermostats do not

require a 24vac common connection.

Powering the W7220 (24vac) -

The W7220 is powered from the JCI unit’s

microprocessor board at the G-Out pin whenever the

fan of the evaporator section is operating. To ensure

that the W7220 is continuously powered, the fan

switch on the thermostat sub-base should be left on

at all times.

High Enthalpy Sequence:

Enthalpy sensor C7400S on all units should be

located in the outdoor air duct. When the outside air

enthalpy exceeds the enthalpy set-point, the

economizer W7220 module Y1-In and Y1-Out

terminals are closed and economizer will be forced

into the minimum damper position setting. The JCI

unit’s microprocessor board will control cooling

requirements.

Low Enthalpy Sequence:

When the outside air enthalpy is below the enthalpy

set-point, W7220 economizer Y1-In and Y1-Out

terminals are opened and free cooling is activated.

The JCI unit’s microprocessor board turns off

compressor operation.

Damper Modulation:

On all JCI units' the C7250A temperature sensor

should be located in the supply discharge air duct.

Locating the sensor in the discharge air provides

effective 'low-limit' sensing and control. The outside-

air damper remains at minimum position if the

discharge air temperature is below 50

F or 10

C. If

the discharge air temperature is between 50

to 56

F (10

to 13.3

C) the outside air damper will

modulate between minimum position and fully open.

Above 56

F (13.3

C) the outside air damper will

remain in the fully open position.

Occupied:

The OCCUPIED harness terminal is not connected

to the economizer OCC terminal in the economizer

box. It has been provided if site conditions require

field connection of an Occupied function. Consult the

Honeywell JADE - W7220 Economizer Controller

Manual for more information.
