KMC Controls FlexStat User Manual

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 conguration 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 aempt 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.)

• Clears present values.
• Restores the object database/conguration 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

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 seings:
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 buon and then
Enter or just let the display time-out).
3. After the FlexStat has restarted, review the set-
tings and recongure as needed.
