Adjusting the Light Level
This feature is factory set at maximum, so that even the brightest light will not prevent the sensor
from turning the load ON when it detects occupancy. If this feature is not needed, leave the light level
at maximum, fully clockwise.
The light level must be adjusted when lights would normally be turned OFF because there is enough
natural illumintation. Each RH-250 may have a different light level setting.
1. Set all RH-250s to Mode 1 (Manual-ON) - except for the one that you're adjusting.
2. Set the RH-250 you're adjusting so that it is in Mode 2 (Automatic-ON).
3. Reduce the time delay to 15 seconds.
4. Adjust the Light Level trimpot to minimum (fully counter-clockwise) on the unit that you're
adjusting. Move out of the coverage area. Let the sensor time out so lights are OFF and then
wait 30 seconds more.
5. Without casting a shadow on the sensor, enter the area. The lights should remain OFF.
Adjust the Light Level trimpot clockwise in small increments. After each adjustment, wait 5-10
seconds to see if the lights turn ON.
Continue this procedure until the lights turn ON. At this setting the light will not turn ON automatically
with occupancy if the light level measured at this sensor is above the current natural illumination.
6. Repeat the process (beginning with step 1) for each RH-250 in your multi-way configuration
until the Light Level has been adjusted properly in all of them.
7. When you have finished adjusting the Light Level of all the RH-250s, return them all to Mode 2.
8. Reset the time delay to the desired setting in all units.
Warning: Do not overturn the Light Level adjustment trimpot!
To test the detection coverage:
1. Press and hold the ON/OFF button. After 10 seconds the lighted switch turns off. The load turns ON if it was not already ON. The sensor is
now in a TEST mode that lasts 5 minutes. (You can end the TEST mode sooner by pressing the ON/OFF button for another 10 seconds).
During the TEST mode, the controlled load turns ON for 5 seconds each time the sensor that initiated the TEST mode detects occupancy.
2. Move out of the coverage area or stand very still. The controlled load turns OFF after 5 seconds if no motion is detected.
3. Move into the coverage area for the unit that initiated the TEST mode. The controlled load turns ON for 5 seconds each time the sensor
detects motion. After 5 seconds expire without motion detection, the load turns OFF. The controlled load turns ON automatically with the
next motion detection and stays ON for 5 seconds.
4. Repeat as necessary to ensure that the desired coverage areas are within detection range.
You can do this test for each RH-250 in your multi-way configuration. So that you can determine the actual coverage area for each multi-way
switch individually, only the RH-250 that is in TEST mode will control the load.
Lighted switch is OFF, no load response to ON/OFF button press:
• Make certain that the circuit breaker is on and functioning.
Lighted switch is ON, no load response to ON/OFF button press:
• Check the lamp and/or motor switch on the fan mechanism.
Load will not turn OFF automatically:
• Press ON/OFF button. If the controlled load turns OFF, go to next step.
• The time delay can be set from 15 seconds to 30 minutes. Check the time delay setting for each RH-250 in your multi-way
configuration. Ensure that all RH-250s have the same time delay setting.
• Ensure that there is no movement within the coverage area for all the sensors related to the load for the set time delay. Hot air
currents and heat radiant devices can cause false detection. Make sure the sensor is at least 6 feet (2 meters) away from devices
that are a significant heat source (e.g. heater, heater vent, high wattage light bulb).
Load will not turn ON automatically when the area is occupied and the sensors are in Mode 2 (lighted switch is ON):
• Press ON/OFF button. If the load turns ON, check the Light Level setting. The light level can prevent the sensor from turning ON
the load automatically.
• Make sure the sensor lenses are not blocked and that you are within the coverage area of at least one sensor.
• If the load does not turn ON when you press the ON/OFF button, check the light bulb and/or motor switch on the fan mechanism.
If load does not respond properly after following troubleshooting, turn OFF power to the circuit then check wire connections or call technical
support.
Wattstopper RH wall switches fit behind industry standard decorator style switch cover plates.
