If you have a digital control, it is designed to flash "FF" on the display to notify you that a problem may have been discovered. Gradient controls and warming throw controls use a blinking indicator light for this purpose.

Follow the instructions on the flag tag to reset the control or follow the steps below.
  • Unplug the system from wall outlet.
  • Check that the control is well connected to the module.
  • Plug the power cord into the wall outlet.
  • Set the control to "on".
If the system still does not operate, disconnect the power cord and contact us.
