DELETE ALARM?
NO YES
A flashing “SERVICE” on the Home screen indicates
an alarm. To view and delete alarms, press:
1. Right to move among fields.
2. Enter to select. (Enter on Alarm Details screen to
delete the alarm.)
3. Left to go back one page.
Built-in alarms are triggered under these conditions
(as applicable to model and configured options):
• Space Temp Alarm—temperature outside the
range of 56 to 86° F for over 300 seconds. (The
monitored object is AV40, mapped from AI1 and/
or AI7.)
• Space Humidity Alarm—humidity above 65%
for over 300 seconds. This is available only in
FlexStat models with a humidity sensor and a
dehumidification option selected in the Humid-
ity setup. See Humidity Setup on page 8 . (The
monitored object is AI5.)
• Fan Fail Alarm—no fan status signal within five
seconds of call for fan (and Input 2 is configured
for the fan status sensor option). See Sensor Setup
on page 9 . (The monitored object is BV5, mapped
from AI2.)
• Low Limit Alarm (freeze stat)—mixed air tem-
perature (MAT) is below the adjustable (under
Damper Setup) low limit alarm temp for one
second (when configured for the economizer op-
tion). After a low limit alarm is generated, the
fan will not run until after the FlexStat is re-
started. See Restart under Resetting the FlexStat
on page 26 . See also Damper Setup on page 7 . (The
monitored object is BV4, mapped from AI3.)
• CO
2
Alarm—carbon dioxide level is higher than
1,050 ppm (or lower than 300 ppm, indicating a
sensor error) for more than 450 seconds. This is
available only in FlexStats with a CO
2
sensor and
the DCV option enabled in the Damper setup.
See Damper Setup on page 7 and (Advanced) CO2
Sensor (and DCV) on page 11 . (The monitored ob-
ject is AV78, mapped from AI9 and/or AI10.)
NOTE: Time delays and limits can be modified in
the corresponding Event Enrollment objects
using TotalControl. Additional alarms may
be added using TotalControl up to a total of
ten.
NOTE: See also see (Advanced) Trend Logs on page
