GENERAL SAFETY GUIDLINES
This equipment is a relatively complicated apparatus.
During installation, operation, maintenance or service,
individuals may be exposed to certain components or
conditions including, but not limited to: refrigerants , oils,
materials under pressure, rotating components and
both high and low voltage. Each of these items has the
potential, if misused or handled improperly, to cause
bodily injury or death. It is the obligation and respon-
sibilty of operating/service personnel to identify and
recognize these inherent hazards, protects
themselves, and proceed safely in completing their
tasks. Failure to comply with any of these
requirements could result in serious damage to the
equipment and the property in which it is situated, as
well as sever personal injury or death to themselves
and people at the site.
This document is intended for use by owner-authorized
operating/service personnel. It is expected that this
individual possesses independent training that will en-
able them to perform their assigned tasks properly and
safely. It is essential that, prior to performing any task
on this equipment, this individual shall have read and
understood this document and any referenced materials.
This individual shall also be familiar with and comply with
all applicable governmental standards and regulations
pertaining to the task in question.
SAFETY SYMBOLS
The following symbols are used in this document to alert the reader to areas of potential hazard.
DANGER indicates an imminently haz-
ardous situation which, if not avoided,
will result in death or serious injury.
WARNING indicates a potentially haz-
ardous situation which, if not avoided,
could result in death or serious injury.
CAUTION identifies a hazard which
could lead to damage to the machine,
damage to other equipment and/or
environmental pollution. Usually and
instruction will be given, together with a
brief explanation.
NOTE is used to highlight additional in-
formation which may be helpful to you.
All wiring must be in accordance with published specifications and must be performed ONLY by
qualified service personnel. Johnson Controls will not be responsible for damages/problems
resulting from improper connections to the controls or application of improper control signals.
Failure to follow this will void the manufacturer’s warranty and cause serious damage to property or
injury to persons.

PRIOR TO INSTALLING OR SERVICING THE UNIT, LOCK ALL ELECTRICAL POWER SUPPLY
SWITCHES IN THE OFF POSTION. FAILURE TO DISCONNECT POWER SUPPLY MAY RESULT IN
ELECTRICAL SHOCK OR EVEN DEATH.

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.

Installing Harness (Vertical Units):
1) Working from the side access door, feed the
loose pre-terminated ends of the harness in
through the back of the low voltage section of
the electrical box, through the bushed hole.
2) Connect the harness terminations to the
microprocessor board economizer harness
terminations (Y-Out, G-Out, ECON, and
OCCUPIED), as shown in the electrical
schematic.
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 condenser section secure the harness
to the side of the blower housing 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 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.
