GENERAL INFORMATION

Unpacking

Upon receipt of the equipment be sure to compare the
model number found on the shipping label with the
accessory identification information on the ordering and
shipping document to verify that the correct accessory
has been shipped.

Inspect the carton housing of each ventilator as it is
received, and before signing the freight bill, verify that
all items have been received and that there is no visible
damage (check parts list below). 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.

General

The economizer should only be installed by a trained
heating and air conditioning technician. These
instructions serve as a guide to the technician installing
the ventilator package. They are not intended as a step­by-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.

Economizer Features

• One piece construction – easy to install.

• Exhaust air damper – built in with positive closed
position. Provides exhaust air capability to prevent
pressurization of tight buildings.

• Actuator motor – 24 volt, power open, spring return
with built in torque limiting switch.

to automatically modulate damper position.

Description

The ECON-WD5 and ECON-DB5 ventilators are
designed to be used with the specific models with
"letter" revision codes as designated on the front page
of this installation instructions manual.

The economizer is an electromechanical vent system
designed to provide fresh air to meet indoor air quality
standards.

Models

When installed in the models listed on the front page,
ECON-WD5 and ECON-DB5 provide built-in exhaust
provisions. When the damper blade opens to bring
fresh air in, the damper also opens an exhaust relief.
The exhaust air will flow into the condenser section of
the unit. The condenser fan will help draw exhaust air
out when it is operating with compressor in cooling or
heat pump mode.

Blade Adjustment for Desired
Ventilator Air

The amount of ventilation air supplied by the
commercial room ventilator is dependant on four
factors.

1. Return air duct static pressure drop.

2. Supply air duct static pressure drop.

3. Indoor blower motor speed.

4. Damper blade open position setting.

Refer to the appropriate graph on pages 29 – 31 to
determine minimum blade position settings.

– Push the SELECT (ENTER) BUTTON to choose the

STATUS menu.

– Navigate through the multiple levels of STATUS by

pushing the SCROLL (UP/DOWN) BUTTONS.

– As the STATUS menu simply gives input/output

information in real-time, there is no way to
change or otherwise alter the displayed criteria.
It is simply a window into the operation of the
economizer controller.

– For specific STATUS level information, refer to

Table 6.

NOTE: Upon power-up (or after power failure or low

voltage condition), the controller will begin a 5-minute
time delay before enabling mechanical cooling.

in the form of an alarm in the ALARM(S) menu. If
there is a period of inactivity AND there is an alarm
registering, the controller will randomly scroll through
the ALARM(S) menu items as a screensaver.

Enthalpy Settings

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

ES3 is factory default.

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 34).

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 35).

JADE™ control. Since the OA conditions are above
the preset DRYBULB SET/ENTH CURVE setting

close the Y1-O relay to initiate mechanical cooling.

The economizer damper will remain closed or in
a minimum ventilation setting depending upon

Stage Cooling (if available) closes and sends a
signal to JADE™ control. Since the OA conditions
are still above than the preset DRYBULB SET/

to initiate 2nd stage mechanical cooling. The

economizer damper will remain closed or in a

Balanced Climate Mode – S, Y and Z Option
Economizer Sequence of Operation

Call for cooling and ECONOMIZER IS NOT AVAILABLE
(due to outdoor conditions):

Y1 energizes mechanical cooling and the Balance
Climate fan speed simultaneously. If the outdoor
conditions are not acceptable, the Y2 terminal will
energize full load compressor and increase the fan
speed to the rated airflow. When the temperature drops
below the Y2 setpoint, the unit will return to part load
and Balanced Climate fan speed. When the cooling
call is satisfied, the compressor will shut down and the
economizer will move to minimum position (ventilation
setting) and the fan will continue to run at RATED
airflow if A is energized on the low voltage terminal
strip.

Unit Operation with S (Part Flow), Y and Z (Full Flow) Economizer Options

Single Stage Compressor Units (Balanced Climate Available)

Call for cooling and ECONOMIZER IS AVAILABLE (due
to outdoor conditions):

Two stage cooling thermostat is required and connector
is disconnected at JADE
Balanced Climate mode (see Figure 7 on page 5).

Unit has a call for ventilation: Damper to Min position
and fan will run at RATED airflow. Y1 energizes
economizer and the Balance Climate fan speed
simultaneously. If the temperature continues to rise,
the Y2 terminal will energize part load compressor and
increase the fan speed to the RATED airflow. When the
temperature drops below the Y2 setpoint, the unit will
return to part load and Balanced Climate fan speed.
When the cooling call is satisfied, the compressor will
shut down and the economizer will move to minimum
position (ventilation setting) and the fan will increase
to run at RATED airflow if A is energized on the low
voltage terminal strip.
