Associate Wireless Transmitters to PowPak Dimming Module with 0 –10 V-
Before beginning this step, make sure that there are no other PowPak modules being set up within the same building. It is possible that wireless transmitters from other systems can be incorrectly associated to this module.

On PowPak Dimming Module with 0 –10 V-, hold Toggle button “ u” for 6 seconds until lights ﬂash.
The Load Status LED will begin ﬂashing twice per second.
Hold the indicated button on each transmitter for 6 seconds. Lights will ﬂash to show that wireless transmitters have been associated.
On PowPak Dimming Module with 0 –10 V-, hold Toggle button “ u” for 6 seconds to save association. Lights will ﬂash and LED will quickly blink for 2 seconds.
Permanently install wireless transmitters (consult individual component installation guides for information).

Reset Factory Defaults

Note: In some instances, it may be necessary to reset the PowPak Dimming Module with 0 –10 V- and connected devices back to factory default settings. Before beginning, make sure that all devices are connected and powered.

Rapidly tap the Toggle button “ u” on the PowPak Dimming Module 3 times and hold on the fourth time until the LED begins to ﬂash at a rate of approximately 2 blinks every 1 second; then release the Toggle button “ u” .
Within 3 seconds of the start of ﬂashing of the LED on the PowPak, rapidly tap the Toggle button “ u” on the PowPak Dimming Module 3 times again. Make sure to release the Toggle button “ u” after the third press.
The LED will ﬂash at a rate of 2 blink every 3 seconds and the connected load will cycle 3 times to indicate the unit has been reset to factory defaults.
Note: Any associations or programming previously set up with the PowPak will be erased and will need to be re-programmed.

Calibrate the Radio Powr Savr Daylight Sensor
Daylight Sensor will control all wired ﬁxtures equally.

Press and release the “Cal.” button on the Daylight Sensor.
Test B Set lights in room to desired light level.
Press and hold the “Cal.” button for 6 seconds.
Exit room for 5 minutes to complete calibration.
Note: When calibration has completed, all lights will ﬂash and begin to respond to daylight.
Multiple Daylight Rows (Optional)
For every row of daylighting a separate PowPak Dimming Module with 0 –10 V- must be used. For detailed setup refer to the tuning section of the Radio Powr Savr Daylight Sensor installation guide.
Select the PowPak Dimming Module with 0 –10 V- that you want to adjust by pressing the toggle button.

Set a Favorite Light Level (Optional)
For Pico remote controls with a Favorite button.

Adjust lights to desired level:
Use the Raise button “ ” or Lower button “ ” on the Pico remote control.
Save favorite level:
Press and hold the Favorite button for 6 seconds. The load will ﬂash 3 times to conﬁrm that the Favorite level is saved.

Set Low-End Trim and High-End Trim (Optional)
For best results, minimize the amount of sunlight entering the room before performing the following procedures.

Notes Depending on the ﬁxture manufacturer or load, low-end trim and high-end trim may need to be adjusted.

Trim low-end to ensure a stable light level because some loads will ﬂicker or drop out if trimmed too low.
Be sure that you can turn on the lights to the low-end trim level without any abnormal operation.
The factory default high-end trim is suitable for most applications but can be adjusted as desired.

Low-End Trim

Enter low-end trim adjustment mode:
Press and hold the Lower button “ Δ” on the fixture control for 12 seconds.
The lights will flash and the load status LED will begin flashing.
Adjust the low-end trim:
Use the Raise button “▲” and Lower button “ Δ” on the fixture control to adjust and set the
lights to the desired low-end (1 to 45%).
Save the low-end trim:
Press and hold the Toggle button “ u” for 6 seconds to save setting.
The load status LED will begin flashing and then turn solid to indicate new level has been saved.

High-End Trim

Enter high-end trim adjustment mode:
Press and hold the Raise button “▲” on the fixture control for 12 seconds.
The lights will flash and the load status LED will flash.
Adjust the high-end trim:
Use the Raise button “▲” and Lower button “ Δ” on the fixture control to adjust and set the
lights to the desired high-end (55 to 100%).
Save the high-end trim:
Press and hold the Toggle button “ u” for 6 seconds to save setting.
The load status LED will begin flashing and then turn solid to indicate new level has been saved.

Set Minimum Light Level (Optional)
Certain applications (e.g., hallways), may require that the lights never turn off. For these areas, activate Minimum Light Level
mode.

A Enter minimum light level adjustment mode:
Press and hold Toggle button “ u” and Lower button “ Δ” for 12 seconds. Lights will flash high-low-high and LED will begin flashing.
If lights stop flashing and go to high-end, the minimum light level is set to OFF (default).
If lights stop flashing and go to low-end, the minimum light level is ON and set to low-end.
Change the minimum light level:
Press Raise button “▲” to set minimum light level to low-end.
Press Lower button “ Δ” to set minimum light level to OFF.
Save the minimum light level:
Press and hold Toggle button “ u” for 6 seconds. LED will quickly flash to indicate that new level has been saved.

Set Occupancy Light Levels (Optional)
Note: Unoccupied light level is always the minimum light level and cannot be adjusted.

A Set desired occupancy light levels:
Use the Raise/Lower buttons “▲ / Δ” on the PowPak Dimming Module with 0 –10 V- or the Raise/Lower buttons “ / ” on all associated Pico Remote Controls to dim the lights to the desired level. Note: Setting lights to OFF during this step will make that control module unaffected by occupancy (will function as vacancy only).
B Save occupancy light levels:
Press and hold Test button for 6 seconds on any associated Radio Powr Savr Occupancy Sensor without a Lights On
button. Release when the sensor lens starts to flash. Or, press and hold Lights On button for 6 seconds on any associated Radio Powr Savr Occupancy Sensor. Release when the sensor lens starts to flash.
