TEST
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
59) for more
information.
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.
Service Test
can be turned on or off from a BACview device, Field Assistant, or the i-Vu application. Select
Default Value
of
Enable
to turn on and
Disable
to turn off.
NOTES
Service Test
mode is password-protected when accessed from a BACview device.
Service Test
allows testing of each controller output.
Binary Service Test
functions are on when the
Default Value
is set to
Enable
and off when set to
Disable
.
The output of the
Analog Service Test
is controlled by the percentage (0-100%) entered into the
Default
Value
.
It is recommended to return every
Service Test
variable to
Disable
or
0.00
after testing each function
(unless that test variable must be active to test a subsequent function, as in
Compressor 2 Test
).
All outputs return to normal operation when
Service Test
is set to
Disable
.
