JADE™ Economizer Module
(MODEL W7220)
PRODUCT DESCRIPTION
The JADE™ Economizer System is an expandable
economizer control system, which includes a W7220
Economizer Module (controller) with an LCD and keypad. The
W7220 can be configured with optional sensors.
The W7220 Economizer Module can be used as a stand-
alone economizer module wired directly to a commercial set
back space thermostat and sensors to provide Outdoor Air
dry-bulb economizer control.
The W7220 Economizer Module can be connected to optional
Sylk Bus sensors for single or differential economizer control.
The W7220 Economizer Module provides power and
communications on the Sylk Bus for the Sylk Bus sensors.
The W7220 Economizer Module automatically detects
sensors by polling the Sylk Bus to determine which sensors
are present. If a sensor loses communications after it has
been detected, the W7220 Economizer indicates a device fail
error on its LCD.
System Components
The JADE™ Economizer System includes an Economizer
Module, 20k mixed air sensor, damper actuator, an optional
CO2sensor, and either a 20k outdoor air temperature sensor
or Sylk Bus sensors for measuring Outdoor Air and return air
enthalpy, temperature, and humidity.
Economizer Module
This is the core of the JADE™ Economizer System and
includes the user interface for the system. The W7220
Economizer Module provides the basic inputs and outputs to
provide simple economizer control. When used with the
optional Sylk Bus sensors, the Economizer Module provides
more advanced economizer functionality.
Sylk Bus Sensors (optional)
The Sylk Bus Sensor is a combination temperature and
humidity sensor which is powered by and communicates on
the Sylk Bus. Up to three sensors may be configured with the
JADE™ Economizer Module.
CO2Sensor (optional)
A CO2sensor (non-communicating or non-Sylk Bus) can be
added for Demand Control Ventilation (DCV).

MOUNTING
This section describes the mounting procedures for the
JADE™ Economizer module and the sensors.
Economizer Module Location and
Mounting
IMPORTANT
Avoid mounting in areas where acid fumes or other
deteriorating vapors can attack the metal parts of the
module’s circuit board, or in areas where escaping
gas or other explosive vapors are present.
IMPORTANT
The module must be mounted in a position that allows
clearance for wiring, servicing, and removal.
Mount the Economizer module on any convenient interior
location using the two mounting holes provided on the
enclosure using #6 or #8 screws (screws are not provided and
must be obtained separately). Use the dimensions in Fig. 1 on
page 2 as a guide.
The Economizer module may be mounted in any orientation.
However, mounting in the orientation shown in Fig. 1 on page 2
permits proper viewing of the LCD display and use of the
keypad.
Sensor Location and Mounting
The JADE™ Economizer W7220 uses digital sensors for
control. The C7250 temperature sensors (MAaand OAb) are
20k NTC. A MA sensor is required for all applications and is
mounted in the mixed air section of a rooftop unit either directly
to the sheet metal using self tapping sheet metal screws or in
the air stream using the duct mounting kit. Duct mount kit is
part number 50053060-001.
Optional OA, RAcand DAdSylkbus sensors communicate with
the W7220 on the two-wire communication bus and can either
be wired using a two pin header or using a side connector.
Each Sylkbus sensor includes a two pin side connector with
the packaging. The SKU number of the Sylkbus sensor is
C7400S. All OA, RA and DA sensors are the same SKU
number. The sensor is set for the appropriate type of sensing
using the three position DIP switch located on the sensor. OA
position is OFF, OFF, OFF; RA is ON, OFF, OFF and DA is
OFF, ON, OFF. During installation the sensors are set for the
usage desired. See “Sylk Bus Sensor Wiring” on page 6 for
DIP switch details.
NOTE: The protective film on the dip switch is only nec-
essary during the factory assembly process. Sim-
ply push through the film to set the dip switches;
this will not harm the device.
Once installed, a sensor can be changed to a different
application by simply changing the DIP switch setting.

Sensor Mounting
The sensors can be mounted directly on to the sheet metal of
unit or can be mounted in the air stream using the duct
mounting kit (order separately).
The kit contains a rod to hold the sensor in the duct, a flange to
secure the sensor rod to the duct wall and fill the hole and a
gasket to prevent air from leaking through the duct wall. There
are five (5) kits in a bag assembly. See Fig. 2.
The rod has slots for threading the wire to prevent loose or
hanging wire in the duct and can be adjusted for 6 to 12 inch
length. The flange has extended relief for ease of mounting.
See 3.
The labels on the sensors and controller are color coded for
ease of installation. Orange sensors can only be wired to
orange terminals on the controller. Brown sensors can only be
wired to S-bus (brown) terminals.
Fig. 2. Duct Mounting Kit (Part No. 50053060-001).
Fig. 3. Duct Mounting Adjustments.
WIRING
All wiring must comply with applicable electrical codes and
ordinances, or as specified on installation wiring diagrams.
Module wiring in the field is terminated to the four screw
terminal blocks located on the left and right sides.
Module wiring at the OEM factory is terminated via the header
pin terminals located on the left and right sides. The header
terminal pins and the terminal blocks have common
terminations for the appropriate input or output. The part
number of the mating female connector for OEMs is 35977.
See OEM wiring diagram in Fig. 13.
The remainder of this section describes the wiring for the
JADE™ Economizer module, W7220A.
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property damage.
Disconnect power supply before beginning wiring, or
making wiring connections, to prevent electrical shock
or equipment damage.
CAUTION
Equipment Damage Hazard.
Electrostatic discharge can short equipment
circuitry.
Ensure that you are properly grounded before handling
the unit.
Economizer Module Wiring Method
Wire the sensors and outputs, then wire the power connection.
Each terminal can accommodate the following gauges of wire:
• Single wire – from 18 AWG to 22 AWG solid or stranded
• Multiple wires – up to two 22 AWG stranded
• For the 24 Vac connections: single wire – from 14 to 18
AWG solid or stranded
• For S-BUS wiring, the sensors may be mounted up to 200
ft. (61 m) from the JADE controller. When the length of wire
is over 100 feet use twisted pair shielded wire.
• All wiring is polarity insensitive.
Prepare wiring for the terminal blocks, as follows:
1. Strip 1/2 in. (13 mm) insulation from the conductor.
2. Cut a single wire to 3/16 in. (5 mm). Insert the wire in the
required terminal location and tighten the screw.
3. If two or more wires are being inserted into one terminal
location, twist the wires together a minimum of three
turns before inserting them to ensure proper electrical
contact. See Fig. 4 on page 5.
4. Cut the twisted end of the wires to 3/16 in. (5 mm) before
inserting them into the terminal and tightening the screw.
5. Pull on each wire in all terminals to check for good
mechanical connection.

Sylk Bus Sensor Wiring
Use Fig. 6 and Table 3 to locate the wiring terminals for each
Sylk Bus sensor.
Use Fig. 6 and Table 4 to set the DIP switches for the desired
use of the sensor.
Fig. 6. Sylk Bus sensor DIP switches.
NOTE: When using the Sylkbus sensors there will be a
slight delay while the Jade controller and the sen-
sor communicate. Analog sensors do not commu-
nicate on the Sylkbus and output a 20k ohm
signal to the Jade controller so the response time
is instantaneous.
Actuator Wiring Options:
1. The JADE economizer controller can only have one (1)
communicating actuator connected to it.
2. Up to four (4) non-communicating and two (2) 2-position
actuators (1 each on EXH1 and AUX1 O)
3. One (1) communicating and up to four (4) non-communi-
cating and two (2) 2-position actuators (1 each on EXH1
and AUX1 O). When using a 2-position actuator on the
AUX1 O, the AUX1 O must be programmed for Exh2 and
the % open is the % open of the outdoor damper when
the 2-pos actuator opens. Connect 24 V to Exh1 and/or
AUX1 O and ground to the Jade "C" terminal.

SETUP AND CONFIGURATION
Before being placed into service, the JADE™ Economizer
module must be setup and configured for the installed system.
IMPORTANT
During setup, the Economizer module is live at all
times.
The setup process uses a hierarchical menu structure that is
easy to use. You press the and arrow buttons to move
forward and backward through the menus and press the ↵
button to select and confirm setup item changes.
Time-out and Screensaver
When no buttons have been pressed for 10 minutes, the LCD
displays a screen saver, which cycles through the Status items.
Each Status items displays in turn and cycles to the next item
after 5 seconds.
Enthalpy Settings
When the OA temperature, enthalpy and dew point are below
the respective setpoints, the Outdoor Air can be used for
economizing. Fig. 16 shows the new single enthalpy
boundaries in the W7220. There are 5 boundaries (setpoints
ES1 through ES5), which are defined by dry bulb temperature,
enthalpy and dew point.
Refer to Table 6 for the ENTH CURVE setpoint values.

For example if you do not have a DCV (CO2) sensor, then none of the DCV parameters appear.
bWhen values are displayed, pressing and holding the or button causes the display to automatically increment.
cn/a = not applicable
dERV Operation: When in Cooling mode AND the conditions are NOT OK for economizing - the ERV terminal will be energized. In
the Heating mode the ERV terminal will be energized when the OA is below the ERV OAT setpoint in the setpoint menu.
eWhen used with Honeywell communicating actuator the damper out is reported in XX.X% open versus XX.X Vd.
fAfter 10 minutes without a command or mode change, the controller will change to normal operation.

Fig. 16. Single Enthalpy curve and boundaries.
To use enthalpy the W7220 must have a C7400S Sylkbus
sensor for OA. The W7220 calculates the enthalpy and dew
point using the OA temperature and humidity input from the OA
sensor. When the OA temperature, OA humidity and OA dew
point are all below the selected boundary, the economizer sets
the economizing mode to YES, economizing is available.
When all of the OA conditions are above the selected
boundary, the conditions are not good to economize and the
mode is set to NO.
Fig. 16 shows the 5 current boundaries. There is also a high
limit boundary for differential enthalpy. The high limit boundary
is ES1 when there are no stages of mechanical cooling
energized and HL when a compressor stage is energized.
Table 6 provides the values for each boundary limit.
Economizer Setup and Configuration
To setup and configure the Economizer module, use the
System Setup menu, the Advanced Setup menu (if necessary),
and the Setpoints menu. Refer to Table 7.

Delay after stage 2 for cool has been active. Turns
on 2nd stage of cooling when economizer is 1st
stage and mechanical cooling is 2nd stage. Allows
three stages of cooling, 1 economizer and 2
mechanical.
OFF = no Stage 3 cooling.
SD DMPR POS CLO CLO
OPN
Indicates shutdown signal from space thermostat
or unitary controller. When controller receives 24
Vac input on the SD terminal in conventional mode,
the OA damper will open if programmed for OPN
and OA damper will close if programmed for CLO.
All other controls, e.g., fans, etc. will shut off.
DCVCAL ENA MAN MAN (manual)
AUTO
Turns on the DCV automatic control of the
dampers. Resets ventilation based on the RA, OA
and MA sensor conditions. See Product Data sheet
63-2700 for details. Requires all 3 RA, OA and MA
sensors.
This operation is not operable when 2-speed fan
mode enabled.
MAT T CAL 0.0F +/-2.5F Allows for the operator to adjust for an out of
calibration temperature sensor
OA T CAL 0.0F +/-2.5F Allows for the operator to adjust for an out of
calibration temperature sensor
OA H CAL 0% RH +/-10% RH Allows for the operator to adjust for an out of
calibration humidity sensor
RA T CAL 0.0F +/-2.5F Allows for the operator to adjust for an out of
calibration temperature sensor
RA H CAL 0% RH +/-10% Allows for the operator to adjust for an out of
calibration humidity sensor
DA T CAL 0.0F +/-2.5F Allows for the operator to adjust for an out of
calibration temperature sensor
2SP FAN DELAY 5 Minutes 0 to 20 minutes in 1
minute increments.
When in economizing mode this is the delay for the
high speed fan to try to satisfy the call for second
stage cooling before the first stage mechanical
cooling is enabled.
