Screen Adjustment

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

wall switch and remove the switch from the junction box.

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

They are black round buttons on silver plates. 

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

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

CAUTION: Do not adjust for more drop than what was 
ordered. At least 1–1/2 wraps of fabric must remain on  
the roller. 

ATTENTION! N'effectuez pas de réglage pour obtenir un 

déroulement supérieur à celui commandé. Au moins 1 à 

1/2 tour de toile doit être maintenu sur le cylindre.

 

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.

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

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

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

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

down buttons on the switch to operate the screen.

6.  Replace the switch and cover plate on the wall.
 

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.

Tensioned Screens

Models with tab-tensioned surfaces are standard with 12" of black 
drop at the top.

CAUTION: Adjusting the down limit switch for less drop 

by more  than 6" can cause the screen surface to lose 
proper tensioning.
