Troubleshooting
Symptoms
Possible Solutions
Sensor 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
sensor 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
•
Rewire your mechanical switch in a 3-way. 3-way wiring for sensor switch is different than
traditional 3-way wiring.

Wait for 2 minutes
•
The sensor switch will manually control the load after the first 10 seconds.
• Once power has been restored, the sensor 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 sensor switch can be
manually turned on or off after the first
10 seconds and will automatically control the
load after 2 minutes.
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 sensor 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 sensor 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.

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

Device will not function if Black wires are not wired.
2
Mechanical switch may be wired to either circuit, and will control both.
Do NOT
wire mechanical switch to both circuits.
3
You may use no more than one mechanical switch with a Dual circuit Dual Tech sensor switch.
