Specifications - Honeywell JADE W7220 Installation Instructions And Operators Manual

JADE™ ECONOMIZER MODULE
PC MOD Tool (optional)
The PC MOD tool is connected to a personal computer and
communicates with the Jade economizer controller via the
Sylk bus. The W7220 PCMOD tool software is free and can
be downloaded from the url in the Accessories section.
Some features on the Jade controller can only be enabled
or disabled using the W7220 PC MOD tool. See the PC
MOD tool options section in Table 5.

SPECIFICATIONS

W7220A Economizer Module
The module is designed for use with any Honeywell 2 to 10
Vdc or Honeywell Sylkbus communicating actuator. The
module includes terminals for a CO
sensor, and an Outdoor Dry Bulb sensor. Enthalpy and
other options are available with Sylk Bus sensors.
User Interface: Provides status for normal operation,
setup parameters, checkout tests, and alarms and error
conditions with a 2-line 16 character LCD display and a
four button keypad.

SENSORS:
NOTE: A Mixed Air (MA) analog sensor is required on all
W7220 units; either an Outdoor Air (OA) sensor
for dry bulb change over or an OA Sylkbus sensor
for outdoor enthalpy change over is required in
addition to the MA sensor. An additional Return

Air (RA) Sylkbus sensor can be added to the
system for differential enthalpy or dry bulb
changeover. For differential dry bulb changeover
a 20k ohm sensor is required in the OA and a
Sylkbus sensor in the RA. Dip switch on RA
Sylkbus sensor must be set in the RA position.
