Honeywell JADE W7220 Installation Instructions And Operators Manual page 8

JADE™ ECONOMIZER MODULE
1. Remove the C7250A dry bulb sensor from the OAT
terminals IF you are using temperature only
economizing change over.
2. If you are using enthalpy change over and have a
C7400S sensor with a date code prior to 1301,
remove the sensor and replace it with one with a
date code after 1301.
3. Connect a C7400S Sylk bus sensor to the S-Bus
terminals (brown colored) on the W7220A Jade
using 18 AWG to 22 AWG solid or stranded wires.
4. Check the STATUS screen for actual outdoor air (OA)
temperature and OA humidity readings.
5. Change the 3-position DIP switch on the C7400S
sensor from 1 OFF, 2 OFF, 3 OFF to 1 ON, 2 ON, 3
ON position and immediately back to 1 OFF, 2 OFF 3
OFF position.
6. The output of the C7400S sensor to the W7220A will
be 40 ºF and 40 %RH which will allow the
economizer to go into free cooling mode
(economizing available).
7. Make sure you have 24 Vac on terminal Y1 In to
simulate a call for cooling.
8. After 15 minutes the C7400S sensor will change
back to the actual OA temperature and humidity.
NOTE: If you removed a dry bulb sensor, remove the
C7400S from the S-bus terminals and replace the
OAT sensor onto the OAT terminals.

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-com-
municating 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 pro-
grammed 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.
CO2 Sensor Wiring
When using the C7232 Honeywell CO
and brown common wires are internally connected and
only one is connected to "IAQ COM" on the Jade. Use the
power from the Jade to power the CO2 sensor OR make
sure the ground for the power supplies are common. See
wiring diagram below for the C7232 and C7632 wiring
diagrams.
NOTE: When using the C7632 (or any 0-10 Vdc CO
sor) with the Jade you will need to set the
CO2ZERO to 400 ppm and the CO2SPAN to
1600 ppm in the ADVANCED SETUP menu.
NOTE: When using the TR40 CO
on the TR40-CO2 to 6. Only one TR40 CO
can be used with the Jade economizer controller.
Address 6 is for a CO
communicating actuator.
