JADE ™ ECONOMIZER MODULE
62-0331—11 2
INSTALLATION AND SETUP
The Economizer module may be mounted in any orientation.
However, mounting in the orientation shown above permits
proper viewing of the LCD display and use of the keypad.
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 discon-
nected 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.
WIRING
All wiring must comply with applicable electrical codes and
ordinances, or as specified on installation wiring diagrams.
Module wiring in the field is terminated to the four screw
terminal blocks located on the left and right sides.
Module wiring at the OEM factory is terminated via the header
pin terminals located on the left and right sides. The header
terminal pins and the terminal blocks have common
terminations for the appropriate input or output. The part
number for the OEM female mating connector is 0039973997.
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
Disconnect power supply before beginning wiring, or
making wiring connections, to prevent electrical shock
or equipment damage.
CAUTION
Equipment Damage Hazard.
Electrostatic discharge can short equipment
circuitry.
Ensure that you are properly grounded before
handling the unit.
Each terminal can accommodate the following gauges of wire:
• Single wire – from 18 AWG to 22 AWG solid or stranded
• Multiple wires – up to two 22 AWG stranded
• For the 24 Vac connections: single wire – from 14 to 18
AWG solid or stranded
For S-BUS wiring, the sensors may be mounted up to 200 ft.
(61 m) from the JADE controller. When the length of wire is
over 100 feet use twisted pair shielded wire.
NOTE: All wiring is polarity insensitive.
Refer to Fig. 1 through Fig. 6 for common wiring
configurations.
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 (2) 2-position
actuators (1 each on EXH1 and AUX1 O)
3. One (1) communicating and up to four (4) non-commu-
nicating and (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.
Note the W7220 economizer will not work with an old “black
motor” M7415; replace the M7415 with a M7215 or MS3103
DCA.
