Screen Adjustment For 120V Screens With A Built-In Low Voltage Control

1. Locate the wall switch and remove the cover plate from the

3-button wall switch and remove the switch from the junction box.

2. Locate the two tactile buttons on the back of the switch. They are

square silver with black round buttons. See wiring diagram.

3. To adjust the down limit switch, press and hold the down tactile

button until the LED on back of switch turns solid red. This will put
the motor in limit set mode. Turn the wall switch over and use
the down button on front of switch. Press and hold until the
desired travel position is reached. If you travel to far down you
can press the up to move the screen upward. If you press and let
go of either up or down button the motor will do a small jog in
that direction for finer adjustment of screen. Once desired
position is reached turn switch over press and hold down tactile
button until the LED on back of switch blinks red twice. The down
limit is now set.

4. To adjust the up limit switch, press and hold the up tactile button

until the LED on back of switch turns solid green. This will put the
motor in limit set mode. Turn the wall switch over and use the up
button on front of switch. Press and hold until the desired travel

position is reached. If you travel to far up you can press the down
to move the screen downward. If you press and let go of either up
or down button the motor will do a small jog in that direction for
finer adjustment of screen. Once desired position is reached turn
switch over press and hold up tactile button until the LED on back
of switch blinks green twice. The up limit is now set.

5. To test limit switch setting, press and release the up or down

button on the wall switch to operate the screen.

6. Replace switch and cover plate on the wall.

NOTE: If the screen is in limit set mode and no buttons are
pushed for 20 seconds, the LED on the back of the wall switch
will turn off, the motor will return to run mode and no changes will
be saved. If this occurs, return to step 3 for down limit adjustment
or step 4 for up limit adjustment.

IMPORTANT NOTE: The wall switch is REQUIRED to make any
limit switch adjustments, EVEN if a third party control system is
used. Therefore, it is advised to wire the switch or provide a
3-conductor connection that is accessible.
