REMOTE (DOWNSTAIRS) MONITORING OF
CONTROLLER’S FAULT DETECTION AND
DIAGNOSTICS
Many codes including IECC, Title 24, and ASHRAE 90.1 require
that the economizer’s faults be accessible by operating or service
personal, or annunciated locally on zone thermostat. To setup
remote monitoring on the controller, under SYSTEM SETUP,
AUX1-OUT must be set to SYS.
The latest versions of Honeywell’s TH8321WF or TH8321R
thermostats are options for meeting this requirement. Figure 33
shows an example of the thermostat wiring to the Jade controller.
Follow instructions provided with Honeywell thermostat.

Another option that is acceptable to some codes is an annunciator
light visible by service personnel. See Figure 34 for typical wiring
to the Jade controller. Refer to codes for proper labeling of light.
