GENERAL
General Information
The economizer should only be installed by a trained
heating and air conditioning technician. These
instructions serve as a guide to the technician
installing an economizer package, not as a step-by-step
procedure with which the mechanically inclined owner
can install the package.
The economizer housing is shipped in one carton,
which contains the electrical harness, miscellaneous
hardware and installation instructions.
The economizer installation requires the use of a 2-stage
cooling thermostat (if there is not one already present)
and requisite amounts of low voltage conductor wire for
two-stage cooling. The number of low-voltage control
conductors will vary depending upon application.
If using a master controller, the MC4002 controller is
designed specically to control two (2) redundant wall
mount units equipped with economizers.
Any wall mount unit equipped with an economizer must
also have a factory/eld installed low ambient control.
Please refer to appropriate model/year Specication
Sheet for requisite eld installed low ambient control
kit part numbers.
Field-Supplied Tools Needed
• Appropriate personal protection equipment,
including gloves and safety glasses
• 5/16" nut driver
• Phillips head screwdriver
• Small flat head screwdriver for securing wire in
terminal blocks
• Electrical tools
• Multimeter
Unpacking
Upon receipt of the equipment, be sure to compare the
model number found on the shipping label with the
accessory identication information on the orders and
shipping document to verify that the correct accessory
has been shipped.
Inspect the carton housing of each economizer assembly
as it is received and, before signing the freight bill, verify
that all items have been received and there is no visible
damage. Note any shortages or damage on all copies
of the freight bill. The receiving party must contact the
last carrier immediately, preferably in writing, requesting
inspection by the carrier’s agent. Concealed damage not
discovered until after loading must be reported to the
carrier within 15 days of its receipt.
Description
ECON-DB and ECON-WD economizers are designed
to be used with the wall mount series air conditioners
and heat pumps, shown in Table 1, equipped with
low ambient controls. They are electromechanical
economizer systems designed to provide “free” cooling
where the outdoor air temperature/enthalpy is cool
enough to provide the needed cooling without running
the compressor, or in addition to the compressor. When
cooling is required, the system automatically takes
advantage of cold outdoor air when available and uses
it for rst stage cooling. This then reduces the need
to run the air conditioning compressor providing lower
operating costs and increasing the service life of the
equipment. If the outdoor air temperature/enthalpy
is too warm to be sufcient for cooling, the dry bulb
outdoor air temperature sensor detects the condition
and automatically closes the outdoor air intake/exhaust
damper, opens the return air damper and switches to
compressor-only operation.
Without attention from the end user, the economizer
assembly is meant to automatically achieve maximum
savings while ensuring appropriately cool space
temperatures. The economizer utilizes a fully
modulating damper actuator, which will control intake/
exhaust in order to obtain and maintain a factory-set
minimum supply air temperature. As a secondary
feature, the economizer assembly can be programmed
for a minimum ventilation based on an “occupied”
(or otherwise dedicated) 24V signal to satisfy fresh
air ventilation on populated structures or dilution of
internal pollutants.
ECON-DB and ECON-WD Series economizers are not
for use with variable capacity ECU models.

with the economizer. If the lters are set at a
30°angle, they must be removed and discarded for
economizer installation. The circuit breaker offset
plate must be loosened and moved slightly to gain
access to several of the screws holding the lter
brackets in place. Tighten screws holding control
panel after lter brackets have been removed.
If lter brackets were removed in Step 6, proceed to
Step 7. If the brackets were not removed, proceed

Economizer Checkout
Since observation of motor/damper operation is difcult
after air hood installation, it is recommended the unit
be enabled for start-up now. If no power is available, or
if immediate start-up is not desired, continue with the
basic installation process by skipping to Step 4. The air
hood assembly can be partially disassembled at a later
time for start-up/checkout procedures.
1. Attach wall unit outer and indoor control panel
doors.
2. Turn power to unit on.
3. Complete economizer checkout using economizer
control touchpad (see CHECKOUT on page 17).
4. After conrming economizer operation, attach the
economizer hood mist eliminator (with airow arrow
pointed towards unit), control door and front door.
Control Wiring Connection Diagrams
The control wiring diagrams on pages 11 – 14
represent typical control wiring for single units
controlled by individual thermostats. If thermostats
other than those referenced are used, the installer must
verify output functions accordingly.
For dual unit installation utilizing lead/lag controller
systems, complete details are contained in MC4002
Series Lead/Lag Controller installation manual 2100-
614. For operation with MV5000 lead/lag controller,
see MV5000 installation manual 2100-636.

Enthalpy Settings
If economizer is enthalpy-based and was shipped with
the temp/humidity sensor, the economizer must be
programmed for the specic enthalpy curve boundary
desired for “free” outdoor cooling. The available
enthalpy boundaries are all subject to specic OA
temperature, OA humidity and OA dew points. If all of
the OA conditions are below the specic points outlined
in each boundary, the conditions are good to economize
and economizer mode is set to “YES”. If some or all
the OA conditions are above the specic points outlined
in each boundary, the conditions are not good to
economize and the economizer mode is set to “NO”.
ES3 is factory default.

Economizer Sequence of Operation
Condition – Cool/Dry OA Conditions
• 1st Stage Cooling closes and sends signal to
JADE™ control. Since the air temperature outside
is cooler than the preset DRYBULB SET setting,
or is below the ENTH CURVE boundary in the
SETPOINTS menu, the actuator will power the
economizer damper to “economizer” mode as the
indoor blower motor starts. The mixed air sensor
senses a mixture of return air and cool outdoor
air and modulates opening to achieve preset MAT
SET setting in SETPOINTS menu. Compressor
operation is inhibited (see Figure 14).
• 2nd Stage Cooling closes and sends a signal to
JADE™ control, which closes the Y1-O relay to
begin mechanical cooling. The economizer damper
REMAINS OPEN in tandem operation with the
compressor as long as the OA conditions do not
drop below the preset DRYBULB SET/ENTH
CURVE settings in the SETPOINTS menu (see
Figure 15).
• 3rd Stage Cooling (if available) closes and sends a
signal to JADE™ control, which closes the Y2-O
relay to begin 2nd stage mechanical cooling. The
economizer damper REMAINS OPEN in tandem
operation with the compressor as long as the
temperature outside does not drop below the
preset DRYBULB SET setting in the SETPOINTS
menu (see Figure 15).
Condition – Warm/Humid OA Conditions
• 1st Stage Cooling closes and sends signal to
JADE™ control. Since the OA conditions are above
the preset DRYBULB SET/ENTH CURVE setting
in the SETPOINTS menu, the control will simply
close the Y1-O relay to initiate mechanical cooling.
The economizer damper will remain closed or in
a minimum ventilation setting depending upon
occupied status (see Figure 16).
• 2nd Stage Cooling (if available) closes and sends a
signal to JADE™ control. Since the OA conditions
are still above than the preset DRYBULB SET/
ENTH CURVE setting in the SETPOINTS menu,
the control will simply close the Y2-O relay
to initiate 2nd stage mechanical cooling. The
economizer damper will remain closed or in a
minimum ventilation setting depending upon
occupied status (see Figure 16).
