Troubleshooting
Symptoms Possible Solutions
Sensing switch
is unpowered, or
is powered, but
does not turn
lights ON.
• If installed in a 3-way with
another mechanical switch, be
sure to rewire the mechanical
switch using Wiring step 2B.
Power can’t be
switched ON or
OFF with newly
installed sensing
switch.
• Check wiring; neutral wire must
be connected for product to
function.
Lights do not turn
ON when space is
occupied.
• Off-While-Occupied mode is
Enabled and the timeout has
not expired.
• Sensor mode is set to vacancy.
• Sensor is set to one of the
Ambient Light Detection (ALD)
settings and the room is too
bright for the current light level
setting.
• Sensor does not have full view
of the room. Move objects
blocking sensor’s line-of-sight.
•Before installing wallplate, program all desired settings. See back for programming instructions.
• For additional wiring instructions, including wiring for two separate breaker feeds, please visit
www.Lutron.com/DTMaestroInstall

troubleshooting, and product information
please visit:

4Wait for 2 minutes
• The sensing switch will manually control the load after the first 10 seconds.
• Once power has been restored, the sensing switch will automatically control the load after the first
2 minutes.
Important Notes
Please read before installing.
1. Neutral wire required.
2. Device will not function if Black wires (Circuit 1/
Line 1) are not wired.
3. This product is rated to control 6 A per circuit.
Circuits may NOT be wired in parallel to control
loads greater than 6 A.
4. When power is applied, the sensing switch
can be manually turned on or off after the first
10 seconds and will automatically control the
load after 2minutes.
5. CAUTION: Risk of Electric Shock— More than
one disconnect switch may be required to de-
energize the equipment before installing the unit,
rewiring, or replacing bulbs.
6. The sensing switch requires an unobstructed
view of the room and line-of-sight to detect
motion.
7. Hot objects or moving air currents can affect
the performance of the sensing switch and
may cause the sensor to turn on unexpectedly
or maintain its current state longer than
desired.
8. CAUTION: To reduce the risk of overheating
and possible damage to other equipment,
DO NOT use to control receptacles.
9. Install in accordance with all national and local
electrical codes.
10. For indoor use only. Operate between 32°F
and 104°F (0 °C and 40 °C).
11. Clean with a soft damp cloth only. DO NOT
use any chemical cleaners.
B
. 3-Way with Mechanical Switch
• Rewire your mechanical switch in a 3-way. 3-way wiring for sensing switch is different than
traditional 3-way wiring.

Two Line Wiring:
Wiring must comply with NEC code for wiring Multiple Branch Circuits: Where two or more branch
circuits supply devices or equipment on the same yoke, a means to simultaneously disconnect
the ungrounded conductors supplying those devices shall be provided at the point at which the
branch circuits originate.
Two circuits, each rated at:
Black-Orange
Ground
1Device will not function if Black wires are not wired.
2Mechanical switch may be wired to either circuit, and will control both. Do NOT wire mechanical switch to both circuits.
3You may use no more than one mechanical switch with a Dual circuit Dual Tech sensor switch.
