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 disconnected
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.

MOUNTING
This section describes the mounting procedures for the
JADE™ Economizer module and the sensors.
Economizer Module Location and
Mounting
IMPORTANT
Avoid mounting in areas where acid fumes or other
deteriorating vapors can attack the metal parts of
the module's circuit board, or in areas where
escaping gas or other explosive vapors are
present.
IMPORTANT
The module must be mounted in a position that
allows clearance for wiring, servicing, and removal.
Mount the Economizer module on any convenient interior
location using the two mounting holes provided on the
enclosure using #6 or #8 screws (screws are not provided
and must be obtained separately). Use the dimensions in
Fig. 1 on page 3 as a guide.
The Economizer module may be mounted in any
orientation. However, mounting in the orientation shown
in Fig. 1 on page 3 permits proper viewing of the LCD
display and use of the keypad.
Sensor Location and Mounting
The JADE™ Economizer W7220 uses digital and
communicating sensors for control. The C7250
temperature sensors (MA
