CAUTION If multiple controllers share power but polarity was not maintained when they were wired, the
difference between the controller's ground and the computer's AC power ground could damage the USB Link and
the controller. If you are not sure of the wiring polarity, use a USB isolator between the computer and the USB
Link. Purchase a USB isolator online from a third-party manufacturer.
Service Test
Navigation:
i-Vu / Field Assistant:
Service Test can be used to verify proper operation of compressors, heating stages, indoor fan, power exhaust
fans, economizer, and dehumidification. It is highly recommended to use Service Test at initial system start-up
and during troubleshooting. See Appendix A: Points/Properties (page 62) for more information.
To activate Service Test, the unit must be shut down first. In Field Assistant, or the i-Vu® interface, you can verify
on the Properties > BACnet Objects tab that the BBV System is shut down shows Yes.
Service Test can be turned on or off from a Field Assistant or i-Vu® interface in Properties > Service Configuration
(page 80), but not from an Equipment Touch. Select Default Value of Enable to turn on and Disable to turn off.
Service Test differs from normal operation as follows:
•
Outdoor air temperature limits for cooling circuits, economizer, and heating are ignored.
•
Normal compressor time guards and other staging delays are ignored.
•
Alarm statuses (except Fire and Safety Chain) are ignored, but all alarms and alerts are still broadcast on the
network, if applicable.
