Section 11 - W7220 JADE™ Economizer Module
63-8594-02 Honeywell Economizers 108
Table 2. Economizer Module - Right hand
terminal blocks.
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-communicating 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 programmed 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.

Sensor Wiring
When using the C7232 Honeywell CO
2
sensors the black 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 CO
2
sensor OR make sure the ground for the
power supplies are common. See wiring
diagram below for the C7232 and C7632
wiring diagrams.
