STEP 4 - MAKING ADJUSTMENTS
(Optional: Only required if factory settings are not preferred.)
• To move from operation mode into set-up mode: remove the plastic plug located in the rear of the sensor module and press the set-up
mode button once. A pencil or small screwdriver may be required. When done, place the plug back in the hole.
4.1 Adjusting Sensing Distances:
• Sequences of red lights will intermittently strobe across the sensor window, followed by a number of red lights which stay on to indicate
the current sensing distance.
Pre-set sensing distances are:
Water Closet Urinal
1 light 24” 1 light 12”
2 lights 32” 2 lights 16”
3 lights 40” (factory set) 3 lights 20” (factory set)
4 lights 48” 4 lights 24”
5 lights 56” 5 lights 28”
• A pulsating blue light on the far left of the sensor window will indicate if an object is detected. However, the sensing distance could be
set at a distance greater or shorter than the desired activating position.
• To ensure sensing distance is set to precise desired position, stand at desired activating distance.
• If the pulsating blue light is not present, press the override button (the red lights will increment).
• Continuing to press the override button will eventually loop the sensing distance back to 1 light (12” sensing distance for urinal, 24”
sensing distance for water closet).
• Press override button until pulsating blue light is present. The blue light indicates that the sensing distance has been adjusted to a
position that is detecting you.
Water closet only:
• Now stand back and ensure that the pulsating blue light disappears when you stand near the door of the water closet.
• Ensure that the door is not being detected as well. If so, decrease the range increment by 1 light (this is achieved by pressing the
override button until the lights loop back around to a setting that is one less the previous setting).
• Once again, verify that the sensor is not detecting the water closet door. If not, the sensor is now set at your desired position.
• The sensing distance for water closets can be set between 24” and 56”, and for urinals between 12” and 28”.
• If all adjustments have been completed, press and hold down the manual override button for 5 seconds. For water closets; this will
return the valve to operation mode. For urinals; this will advance the distance adjustment mode into the 24 Hour Flush adjustment
mode.
4.2 Adjusting 24 Hour Flush (for Urinal applications):
• When 3 red lights in the centre of the sensor window are on, 24 hour ush is on.
• When the red light in the middle of the 3 lights is o, the 24 hour ush is o.
• Press manual override button to toggle between on and o mode.
• If all adjustments have been completed, press and hold down the manual override button for 5 seconds until all lights go out.
