SENSOR ADJUSTMENT & PROGRAMMING
To program the RH-250, you use controls
located under the ON/OFF button. The wall
switch cover plate must be removed to gain
access to the mode button and adjustment
trimpots under the ON/OFF button.
For multi-way operation, the
Operating Mode and the Time Delay
adjustments should be the same in all
sensors related to the same load.
1. Firmly grasp the side edges of the Lock
Bar and gently pull it away from the
switch face until it clicks. Do NOT attempt
to pull the Lock Bar off of the switch!
2. Firmly grasp the side edges of the ON/
OFF button. Slide the button downward
approximately 1/2 inch to expose the
mode button and adjustment trimpots.
Setting up the Operating Mode
Select the operating mode by pressing the Mode button. The amber LED behind
the switch button blinks to indicate the selected mode. The blink pattern repeats
three times:
• One blink indicates Mode 1 (Vacancy Sensor Operation), Manual-ON/OFF,
Auto-OFF
• Two blinks indicates Mode 2 (Occupancy Sensor Operation), Auto-ON/OFF with
manual control and reset to auto (after 5 minutes of vacancy)
To change the mode, press the Mode button once to set the unit to mode 1 or
press the Mode button twice to set the unit to mode 2. The LED blinks to indicate
the selected mode. It repeats the selected mode three times. After that, the unit
operates in the indicated mode.
Adjusting the Time Delay
Turn the right trimpot counter-clockwise to reduce the amount of time the lights
will remain ON after the last motion detection (minimum = 15 seconds). Turn the
same trimpot clockwise to increase this time delay (maximum = 30 minutes).
You can only select the following values: 15 seconds/5 minutes/15 minutes/30
minutes.
Warning: Do not overturn the Time Delay adjustment trimpot!
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.
Set the RH-250 you’re adjusting so that it is in Mode 2 (Automatic-ON).
2. Reduce the time delay to 15 seconds.
3. 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.
4. 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.
5. 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.
6. When you have finished adjusting the Light Level of all the RH-250s, return
them all to Mode 2.
7. Reset the time delay to the desired setting in all units.
Warning: Do not overturn the Light Level adjustment trimpot!
