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 outside 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 outside 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 MATaand OATbsensors are 20k NTC sensors. A
MAT 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.
Optional OAT, RATcand DATdSylkbus 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 Euro
connector with the packaging. The SKU number of the Sylkbus
sensor is C7400S. All OAT, RAT and DAT 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. OAT position is OFF, OFF, OFF; RAT is ON, OFF, OFF
and DAT 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.
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.
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. 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 or 12 inch
length. The flange has extended relief for ease of mounting.
See 3.
Fig. 2. Duct Mounting Kit (Part Nbr. 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 0035977.
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
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.

WIRING APPLICATION
EXAMPLES
This section describes the wiring configurations for the JADE™
Economizer system. The configurations are:
— “Stand-alone Economizer”
— “Economizer with Sylk Bus Sensors” on page 9
Stand-alone Economizer
The most basic configuration is the stand-alone Economizer
(see Fig. 7 and Fig. 8 on page 8).
A stand-alone Economizer is directly wired to sensors,
actuators, thermostat, and mechanical controls in the roof top
unit. It does not require Sylk Bus communications.
