SWITCH SETTINGS
SWITCH 1 – MODE: Controls the operational mode of the sensor. When placed in Test Mode (ON Position), the
sensor will timeout after 8 seconds of no occupancy. The sensor's LED will blink in bursts of 4 to indicate that
Test Mode is active. Note: In any two relay sensor, the primary lights will turn off after 8 seconds and the
secondary lights after 10 seconds. If Smart Cycling is enabled, the Primary and Secondary ballast should change
each cycle. NOTE: If both Smart Cycling and Leave On Mode are enabled, the Primary and Secondary ballast will
not cycle during Test Mode. If switch is already in the ON position, turn the switch OFF then back to the ON
position to enter Test Mode. Sensor will automatically exit Test Mode after 1 hour. Sensor detection will be
indicated by a single blink of the LED. To manually exit Test Mode, return switch to the OFF position. Default:
Normal (OFF Position).
SWITCH 2 – SMART CYCLING: Enables Smart Cycling feature on dual relay sensors. This feature extends
lamp life by balancing the cumulative ON times for each relay. Each consecutive cycle automatically swaps the
"Primary" and "Secondary" role of the relays. Default: Enabled (OFF Position).
SWITCH 3 – LEAVE ON: Allows for high/low operation using dual relay sensors. When enabled, the "Secondary"
If Smart Cycling is enabled, the role of "Primary" and
relay will remain ON during unoccupied periods.
"Secondary" is automatically swapped between the two relays for each consecutive cycle. Default: Disabled
(OFF Position).
SWITCH 4 – DAYLIGHT SENSOR SELECTION: Selects either the downward looking or upward looking daylight
sensor. NOTE: Upward looking daylight sensor is only available on end mount versions of the sensor. Default:
Downward (OFF Position).
SWITCHES 5 & 6 – PRIMARY TIMER: Controls time interval
to turn off light(s) controlled by Primary Timer after the lighted
space becomes unoccupied. Available settings are 8, 4, 16,
and 30 minutes. Default: 8 minutes (Switches 5 & 6 – OFF
Position).
SWITCHES 7 & 8 – SECONDARY TIMER: Used on dual relay
sensors only. Controls time interval to turn off light(s) controlled
by Secondary Timer after the lighted space becomes
unoccupied. Available settings are DISABLED (Secondary lights
switch off with Primary), 30, 60, and 90 minutes. Default:
DISABLED (Switches 7 & 8 – OFF Position).
SWITCHES 9, 10, 11 & 12 – DAYLIGHT SENSOR SET POINT LEVELS:
Enables or disables daylight sensor operation. When enabled, the sensor turns lights on in response to
occupancy when light levels are below the daylight sensor set point – set by Switches 9-12. Daylight sensor
setting should be set to a value that turns off artificial lighting when natural light levels reach the designed light
levels at task. To determine this value, light level measurements should be taken when the natural light levels are
at their highest peak (typically between 10am – 2pm). With artificial lighting on, measure the light level at the task
area. When the measurement at task level is twice the design level, measure the light level at the sensor. NOTE:
light meter should be oriented in the same direction as the selected upward or downward looking daylight sensor.
Configure switches 9-12 to the value closet to the meter's reading. Default: Disabled (Switches 9-12 – OFF
Position).
Sensor operation when daylight sensor is disabled:
Single Output Sensor – Occupancy controlled.
Dual Output Sensor – Output 1 & Output 2: Occupancy controlled. Smart Cycling and Leave On Mode
function as normal.
Sensor operation when daylight sensor is enabled:
Single Relay Sensor - Occupancy controlled with daylight override.
Dual Relay Sensor – Relay 1 (red output wire): Controlled by occupancy only; Relay 2 (blue output
wire): Controlled by occupancy with daylight override. Note: If Smart Cycling is enabled, the daylight
override function will alternate between Relay 1 and Relay 2 on consecutive cycles. If Smart Cycling is
disabled, daylight override will remain with relay 1 (red output wire). Daylight sensor override can be
enabled for both relays by enabling Leave On Mode (Switch 3 = ON) and setting the Secondary Timer
to 30 minutes (Switch 5 = OFF, Switch 6 = ON).

Note: Dead band is factory set. To prevent unwanted cycling, the light level at the sensor face must
exceed the FC set point by the amount of dead band before the lights will turn off. Conversely, the light
level must drop below the set point plus the dead band before the lights will turn on.
SWITCH SETTINGS FOR DISABLING ALL SENSOR FUNCTIONALITY
In order to disable all sensor functionality, set DIP switches to the following positions. Note: switch settings
apply to all HMHB models, including single relay versions that do not use switches 7 and 8 in normal
operation. If sensor functionality does not need to be disabled, refer to switch settings guide above.
Switch 2 – Smart Cycling: ON
Switch 3 – Leave On: ON
Switch 7 – Secondary Timer: ON
Switch 8 – Secondary Timer: ON
