W7220 Personal Computer Tool - Honeywell Design and Application Technical Reference Manual

Section 11 - W7220 JADE™ Economizer Module
The W7220 JADE™ economizer controller is
the first Honeywell standalone economizer
that has a microprocessor and therefore
makes it easy for the user to interact with the
controller and provide information and new
functions. However to make the controller a
low cost for all users, the ability to record the
history of the system was not included in the
unit. A separate tool is available that allows
the user to connect the W7220 JADE™
economizer to a personal computer to:
• reduce setup and test time by making it
easy to program the controller using
selectable program parameters for the unit
• record checkout of the economizer system
• provide the ability to monitor ventilation,
economizer operation and other parameters
for local building codes
To use the W7220 PC Module, you'll need:
a personal computer with the Windows XP
Windows 7 or Windows Vista operating
system; a USB cable to connect the PC
Module to the computer; and two wires to
connect the PC Module to the JADE™
controller module.
To connect the PC Module to the JADE™
controller, use a six-pin edge connector that
inserts onto the edge of the PC MOD board
from the side. Tie into Sylk –bus terminals on

the JADE™ controller module system, and
then connect the PC Module to the computer
using the USB cable.
The PC MOD tool is powered through the
Sylk-bus connection to the JADE™ controller.
The complete OS number for the PC MOD
tool is W7220-PCMOD and software to run it
can be downloaded for free at:
www.customer.honeywell.com/
economizertools.
There are two versions of the software, one for
the OEM factory and one for the contractors.
OEMs can use the PC MOD tool to load
default programs for different customers to the
JADE™ logic module without having the
production workers push buttons and possibly
misprogram the logic. They simply download
the correct program from a file created by the
production engineer. After the unit has been
programmed, the operator is able to step
through a checkout procedure to verify the unit
is working and print a report to ship to the
customer. The file can be saved for later use.
Each JADE™ logic module has a serial
number which can be traced back to the
factory to verify that it was working when it left
the factory and to track the programmed
parameters.
The contractor version of the software can be
used in the field to communicate to the JADE's
on the RTU without opening the unit by
connecting 2 wires to the JADE™ via the
S-bus and pulling the wires to a mechanical
room where the 6-pin connector can be
terminated to the wires. The service technician
simply plugs the 6-pin connector into the PC
tool, connects it to the computer and reads the
status of the JADE™ in the RTU. The
contractors may want to have one PC MOD
tool per building, per RTU or per technician.
Extra 6-pin connectors are available in 20 per
bag and can be ordered using the OS number
50048926-002.
