4.13 Controller Replacement
If the troubleshooting procedures in Section 3 identify a
failed controller, use the procedure in this section for
controller r eplacement. Always check the controller
configuration, fuse, wiring, and connections before
replacing the controller.
After replacing the controller, the installer must set the
controller parameters. On the RDC controller, the
installer can use the the controller keypad to set the Uu
and Ec parameters, or use a personal computer running
Kohlerr SiteTecht software. For the DC controller, the
installer can use the key sequence described in these
instructions or use SiteTech software to configure the
controller. Distributors can obtain SiteTech software
from the TechTools site on Kohlernet.
If SiteTecht is used and the old controller is functional,
you may be able to save the current controller settings to
a file before the controller is removed. (Or the controller
settings may have been saved to a file during the
installation process.) Then use SiteTecht to load the
settings onto the new controller after it is installed. See
TP-6701, SiteTecht Software Operation Manual, for
instructions to export and import s ettings.
Note: Export the old controller settings to the new
controller only if you are certain that the settings
are correct. Many controller operation problems
