Optional CO2 Sensor
Any CO2 Sensor which has a 0-10 Vdc output can be used. We
recommend the MicroMetl 9901-0051 Wall or Internal Duct Mount,
or the MicroMetl 9901-0052 External Duct Mount. CO2 connects
to the IAQ outputs of the JADE Controller.
Optional Smoke Detector
The JADE Controller is designed to allow a shutdown command
from devices similar to a Smoke Detector. A Smoke Detector
connects to the AUX inputs of the JADE Controller. However, if the
JADE Controller is previously programmed to interface with a heat
pump, this function may not be available. The only other option is
to route the power to the JADE through a smoke detector, therefore
removing the power if a re or smoke is detected. Normal default
for power off is often a complete closing of all outside dampers.
Warning: Any circumstance which involves emergency shutdown
should be carefully studied and written into company policy. Please
adhere to all applicable electrical, local, and re emergency codes
before integrating emergency devices into your HVAC scheme.
We recommend the MicroMetl 9901-0091 Smoke Detector.
Optional Power Exhaust
MicroMetl carries a large variety of Power Exhausts. To control the
Power Exhaust output, connect to (Ground) GND and EXH1-0 on
the JADE Controller.

STARTUP INSTRUCTIONS
Once the economizer and all electronics are correctly installed and
wired. Apply power to the system and wait sixty minutes before
checking for alarms. This allows time for all the congured devices
(e.g. sensors, actuator) to become operational. The exception is
the MA sensor which will alarm immediately! Upon power up (or
after a power outage or brownout), the W7220 controller module
begins a ve minute power up delay before enabling mechanical
cooling.
Actuator – Communicating
This Actuator Communicates to the JADE Controller and is
required by some codes. It works with JADE to provide improved
control, eld detection, diagnostics, and save time during setup
and testing. Connects to the S-bus and, ACT COM, and ACT 24+
on the JADE Controller.
