ALARM SUMMARY
^/High Pressure
Alarm
When in the stat page, press the
right arrow once to go this screen
NOTE: This FX10 application implements an alarm history which is reset
only by cycling power. This history shows on the Alm-History page. Any
alarm showing 2+ events has occurred more than 2 times.
Alarm lock-outs are reset by cycling power, by pres s ing the “E S C ” and
Return
keys simultaneously for a minimum of 15 seconds, or by
commanding the nviAlarmReset over the BAS network.
Test mode is enabled by holding the ‘E s c’ and Down Arrow s imultaneous ly
for a minimum of 15 seconds and releasing. Test mode times out after 30
minutes, and may als o be ended by pres s ing ‘E S C ’ and Up Arrow
simultaneously and releasing. Test Mode bypasses the On Delay (90 sec)
and Random Start timers for quicker troubleshooting. It also allows cycling
the reversing valve without compressor shutdown.
