Answer
Hi Darsee
here some Nelson models instructions hope yours is here.


Nelson 8100 series
RESET To reset unit to factory defaults, unplug
transformer and remove batteries, wait for
LCD to turn off, then plug transformer back
in and re-install batteries


Nelson 8400 series
You can reset by disconnecting the transformer and pressing the reset sw on the back panel near the batteries.

Nelson Smart-Ez
After installing the battery, press the black reset button on the back of the front panel to reset the
controller (does not affect program(s)). To reset the controller to its default settings, press both the
black reset button and the SELECT key simultaneously. Release reset button before releasing
select key. Close the front panel, being sure not to damage wires. If wires are stiff, you may
find it helpful to pre-bend them. Tighten the panel screw to secure the front panel to the case.
Plug in the AC cord for the transformer or turn on the power source.

Nelson Smart
RESET
When a PLUS4 board is added to a SmartZone? press reset to
update the controller so it recognizes the additional zones. The reset
button is located on the back of the front panel.

To execute a total reset of the controller (return to its default settings
from the factory), press and hold the Current Day button and then
press and release the number 1 button. The controller will return to all
default factory settings, and will be Off.
