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 pressing the “ESC” 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 ‘Esc’ and Down Arrow simultaneously

for a minimum of 15 seconds and releasing. Test mode times out after 30
minutes,

and may also be ended by pressing ‘ESC’ 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.
