MANUAL SCENE MODIFICATION 

Once the US22-40 has been initially configured, it is possible to make scene 
changes (e.g. default scene-link 1 and 2) without configuration software. 
 
1. 

To modify a scene-link for one of a transmitting device’s actuators, set 
all scene devices to the desired light levels and then place them in 
SETUP mode.  Tap the scene actuator (e.g. button 1) on the 
transmitting device exactly 7 times to create the scene and store the 
light levels. 

 
2. 

To add a device

 other than a US22

 to an existing scene, activate the 

scene and set the light level on the device to be added.  Place the 
device in SETUP mode and tap the scene actuator on the transmitting 
device exactly 7 times to modify the scene. 

 

 
3. 

To add a US22

 to an existing scene, activate the scene and set the 

light level of the US22 channel(s) to be added.  Place the US22 in 
setup mode and then to add specific channel(s)…

add channel 1

 by 

tapping the US22 1 time – wait 3 seconds and tap 1 more time 
(green/blue LED flash) ; or 

add channel 2

 by tapping the US22 1 time 

(blue/green LED); or 

add channels 1 and 2

 by tapping the US22 2 

times – wait 3 seconds and tap 2 more times (green/blue LED); all 
followed by tapping the transmitting device’s actuator button 7 times. 

 
4. 

To remove a device from an existing scene, place the device to be 
removed in SETUP mode.  Tap the scene actuator on the transmitting 
device exactly 8 times to modify the scene. 

 
5. 

To change light levels on an existing scene, set the levels as desired 
and tap the scene actuator on the transmitting device exactly 7 times 
to modify the scene. 

TROUBLESHOOTING 

 

PROBLEM PROBABLE 

CAUSE SOLUTION 

Push light pipe (LED indicator) back into position flush with faceplate 
assembly housing. 

Master switch is wired 
properly but has no power 
(e.g. LED indicator is OFF). 

Air gap power disconnect may be disengaged (pulled 
out). 

Test buttons without faceplate with appropriately-sized non-metallic 
object such as a toothpick or golf tee 

3-way remote switch actuator may be binding, 
causing the switch to be stuck ON or OFF. 

Loosen mounting screws on remote switch and/or wallplate to relieve 
pressure on housing. 

Actuator faceplate may not be seated properly on the 
switch body. 

Exercise actuator several times to ensure proper seating and operation.  
If necessary, remove and replace faceplate to ensure proper seating and 
operation. 

Master switch actuator doesn’t 
turn load ON and/or OFF (e.g. 
LED indicator is ON). 

Switch faceplate may be incorrectly selected in 
UPStart 

Select the correct faceplate in UPStart 

Mounting screws may be too tight or j-box may be 
deformed, causing the switch body to warp. 

Loosen mounting screws to relieve pressure on the switch housing. 

Buttons and/or rockers stick or 
don’t actuate properly when 
pressed. 

Actuator faceplate may not be seated properly on the 
switch body. 

Exercise actuator several times to ensure proper seating and operation.  
If necessary, remove and replace faceplate to ensure proper seating and 
operation. 

Switch is overloaded. 

Reduce the power load by removing bulbs from the circuit. 

Load turns ON and OFF 
regularly without actuation or 
command. 

Switch is dimming a load that is not rated for use 
with incandescent dimmers. 

Reconfigure the switch for ON/OFF operation with no dimming (using 
UPStart, for example). 

Communication or switched 
links to other UPB devices are 
intermittent. 

Linked UPB devices are on other phase of the 
homes’ 2 phase power. 

Install an inverting phase coupler at each breaker panel.  Perform 
UPStart ‘Communications Test” tool to measure signal strength and 
presence of noise.
