BEFORE INSTALLATION
IMPORTANT:
A neutral wire is required for the switch towork properly. If the existing wiring does not match
thedescription for a two-pole circuit, or if you do not have aneutral wire, consult a qualifed
electrician.

Detects motion.
●These instructions describe only the 3-way circuit applications.
●For information about other applications,
●consult technical support.
1. Prepare the switch box
●After the power is turned OFF at the circuit breaker box,remove the existing wall plate and
mounting screws. Pull the old switch out from the wall box.
2. Identify the type of circuit
●You may connect the YT-C2 to a single pole or multi-way circuit. If you are unable to clearly
identify some or all of the wires mentioned in this manual, you should consult with a qualifed
electrician.
●In a 3-way circuit (see Fig. 4), two traveler wires connect to both switches. Another wire provides
power from the circuit box to one of the switches. A wire connects from one switch to the load.
A ground wire may also be connected to a ground terminal on the old switches. A neutral wire
should also be present in both wall boxes.
Figure 4: Typical 3-way switch wiring
The YT-C2 Series sensor switch is designed to replace a standard light or fan switch. This device
can automatically turn lights or a fan on and off by detecting motion from a heat-emitting source
such as a person entering an area. The lights or fan will stay on until no motion is detected and
the time delay has expired. This product offers optimal coverage for random traffc areas such
as hallways, stairways, or large spaces with multiple entries. Use indoors only.
●The sensor must have a clear and unobstructed view of the area. If an object blocks the
sensor’s lens, the sensor may not detect motion and may turn the lights or fan off even if
someone is in the area. Windows, glass doors, and other transparent barriers will
obstruct the sensor’s view and prevent motion detection.
●The coverage area data is measured under the best temperature condition (20 to 25˚ C),
and a higher or lower temperature may not leadto an ideal coverage area (see fgures 1 and 2).
WARNING:
●Before installing the YT-C2 Series sensor switch,disconnect power to the
wall switch box by turning off the circuit breaker or removing the fuse for the
circuit.
●For supply connections use 18AWG or larger wires suitable for at least 75°C
●Tightly secure the ground wire to ensure that thesensor functions properly.
AVERTISSEMENT:
●avant d'installer l'interrupteur du capteur de la série YT-C2, débranchez
l'alimentation du boîtier d'interrupteur mural en éteignant le disjoncteur ou
en retirant le fusible du circuit.
●Pour les connexions d'alimentation, WG ou plus adaptés
à au moins 75 ° C
●fxez fermement le l de terre pour vous assurer que le capteur fonctionne

Installation Instructions for YT-C2 Series
YT-C2 Series
Three-Way 180°Occupancy and Vacancy Sensor Switch
Please read all instructions before installing the YT-C2 Series sensor switch.
*Intended for use with electronic ballast, Type ICN-4S54-90C-2LS-G, manufactured by Philips
Lighting Electronics N A.
Thank you for your purchase from Dependabel Direct, your satisfaction
is our top priority. If you have any questions or concerns, please email
YM2108T
REV 1.1
●Occupancy: In occupancy mode (auto on, auto off with auto reset), the lights or fan turn
on automatically when the space is occupied. The YT-C2 Series sensor switch
automatically turns off the lights or fan after the time delay. If the lights or fan are turned
off manually, automatic on is re-enabled when no motion is detected for one minute. This
way, the lights or fan will remain off if they were deliberately turned off.
IMPORTANT: When installing two YT-C2 Series sensor switches,either sensor can turn
the lights on. For the lights to turn off, both sensors must time out, or you must manually turn
them off.
Adjust the Time Delay
The Time Delay Dial, labeled as TIME, controls how long the light or fan stays on after no
motion is detected. The minimum setting is 15 seconds (fully counterclockwise) and the
maximum setting is 30 minutes (fully clockwise). Adjust the setting as desired for your area.
Adjust the Sensitivity Range of the Sensor
●The Sensor Sensitivity Range Dial, labeled as SENSE, lets you adjust the sensor to avoid
unwanted motion detection such as hallway traffc.
●To decrease sensitivity, turn the setting counterclockwise. To increase sensitivity, turn the
setting clockwise. The sensor’s default setting is 3 (75%). You can adjust it from setting
1 (50%) to setting 5 (100%).
Figure 5: Wire diagram for YT-C2 with regular 3-way wall switch
Adjust the Ambient Light Level
The Ambient Light Level Dial, labeled as LIGHT, lets you adjust the sensor to detect whether
other light sources (such as sunlight) are enough to light the space without turning on the
lights. If you would like the sensor to consider the amount of ambient light in your area, turn
the dial counterclockwise. If you would rather not use the ambient light level, leave it on the
maximum, default setting (5). This will allow the sensor to turn the light on and off regardless
of ambient light.
Lights or Fan Will Not Turn On
Push the On/Off button. The load should turn on. If not:
1. Check the light bulb and/or motor switch on the fan.
2. Turn off power to the circuit and check the wire connections.
Lights or Fan Will Not Turn Off
●Ensure that no motion is occurring in the coverage area until the set time period.
●Ensure that the sensor is at least 6 ft (2 m) away from devices that are a signifcant heat
source (e.g., heater, heater vent, and high wattage light bulbs). Hot air currents and heat
-radiating devices (such as 100W incandescent bulbs) can cause false detection.
●Push the On/Off button to Off. If the lights or fan do not turn off, turn off power to the circuit
and check wire connections.
Lights or Fan Turn Off Too Quickly
The time delay or sensitivity range may be improperly set. Refer to the Adjustment and
Programming section.
Lights or Fan Turn on When Movement Is Detected in Adjacent Areas
If the sensor’s location gives it a view of other areas or hallways,the lights will turn on when
motion is detected in those areas. Try adjusting the sensitivity range (refer to the Adjustment
and Programming section). You may need to move the sensor to another location.
Lights or Fan Turn on When the Area is Unoccupied
The sensor may be mounted too closely to an air conditioning or heating vent. Move the
sensor to another location or close the vent.
TROUBLESHOOTING
