BEFORE INSTALLATION

Review the "Specifications" on page 2 before installing the The
JADE™ Economizer System.
When Installing This Product
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous condi-
tion.
2. Check ratings given in instructions and on the product to
ensure the product is suitable for your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
NOTE: Jade will be in the "set up" mode for the first 60
minutes after powered. If a sensor for OA air or
Sylkbus device (sensor, actuator) is disconnected
during the set up mode, the Jade will not alarm
that failure. The 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.

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 (MA
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.

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.
