KMC Controls FlexStat Operation Guide - Manual (Page 27)

FlexStat 27 Operation Guide, Rev. R
A cold start does the following in the FlexStat:
• (After zeroing out objects during the restart
process) returns all object values to their relin-
quished defaults (until they are updated by the
FlexStat’s programs).
• Restarts the controller’s Control Basic programs.
• Leaves configuration and programming intact.
NOTE: Menu changes may take up to about two
minutes to write to nonvolatile Flash
memory. If power to the FlexStat is lost
during this time, changes may be lost.
Restarting the FlexStat from its menu,
TotalControl, or BACstage are the
recommended methods.
NOTE: When power is restored after an outage,
the FlexStat will attempt to do a warm
start as long as the values in RAM are
retained (up to about four hours). If
the the RAM checksum test fails, a cold
start will be done instead. (In custom
Control Basic programming, using the
POWERLOSS command may be desirable
to determine start-up conditions and to take
appropriate actions—see the Help system
in TotalControl or BACstage for more
information.)

WARM START
To perform a WARM start, do one of the following:
• From the FlexStat menu, select Advanced > Re-
start/Restore > Warm Start.
• From TotalControl or BACstage, select Reinitial-
ize Device > Warm Start.
• Momentarily remove power to the FlexStat.
To perform a COLD start, do one of the following:
• From the FlexStat menu, select Advanced > Re-
start/Restore > Cold Start.
• From TotalControl or BACstage, select Reinitial-
ize Device > Cold Start.
Restore Factory
Restore Factory (restoring the FlexStat to the factory
settings) does the following:
• Clears present values.
• Restores the object database/configuration to the
defaults.
• Restarts the controller’s (factory installed) Con-
trol Basic programs.
NOTE: The MAC address and device instance are
not restored to their original defaults, and
custom Control Basic programs are not
deleted. If custom Control Basic programs are
installed, all factory programs are restarted
but all custom Control Basic programs are
halted. Custom programs may be restarted by
loading/running the programs from the CB
Programs menu. See (Advanced) CB (Control
Basic) Programs on page 10 .
CAUTION
When returned to factory defaults, analog out-
puts will go to zero and relays will go to their
normally open state. Before restarting the ther-
mostat, manually override equipment as needed.
CAUTION
After a return to factory defaults, applications are
unconfigured. You must select the desired appli-
cation and appropriate settings before connected
equipment will operate properly. (See
(Advanced)
Application and Additional Setup on page 7 .)
To restore the FlexStat to factory settings:
1. Select Restore Factory from the Advanced > Re-
start/Restore menu.
2. When prompted for the required restart, press
Enter. (To Cancel, press the right button and then
Enter or just let the display time-out).
3. After the FlexStat has restarted, review the set-
tings and reconfigure as needed.
