How to Set Up a Zūm Space and Add Zūm Devices
Once all devices are physically installed in a board room or conference space, a new
Zūm space can be created and devices added.
NOTE: Only set up one Zūm space at a time.
NOTE: For simplified setup of a Zūm space, use the Zūm app on a mobile device.
Step 1 Create a New Zūm Space
Creating a Zūm space defines the area where the devices are located, such as a board
room or conference room. A Zūm space is created with a keypad, dimmer or switch, a
J-box device, or an AV Bridge.
NOTE: Creating a Zūm space can only be performed by one device in the space.
NOTE: A Zūm space cannot be created from a battery-powered keypad.
To create a new Zūm space using a keypad, dimmer, or switch:
1. Press the bottom button 5 times.
2. Press and hold the button until the LED on the device lights (about 10 seconds).
After approximately 3 seconds, the device LED begins slowly flashing. This
indicates that the Zūm space is now created and in Joining mode, allowing you
to add devices.

Calibrate and Test the Daylight Sensor
To enable daylight harvesting, calibrate and then test the daylight sensor after all
devices are installed and powered in the Zūm space.
NOTE: When setting up the daylight sensor, consider the following:
• Only dimmers are capable of adjusting load levels that are driven by daylight
sensor readings.
• Daylighting only operates when Scene 1 is enabled.
• Calibrate the daylight sensor during the day when the sun is bright. Avoid
light fluctuations caused by clouds that are rapidly exposing and hiding the
sun.
• Do not stand between the daylight sensor and the windows. Doing so affects
the readings and can result in poor calibration settings.
Calibrate the Daylight Sensor:
1. Adjust the lights in the room to the desired levels.
NOTE: Take the natural daylight levels into consideration when setting the
load levels. Each dimmer can be set to a different level. Typically, lights closer
to windows are dimmed more than lights away from windows.
NOTE: To prevent daylighting from affecting a dimmer, set the lights on the
dimmer to brighter than scene 1.
2. Press and hold the button for 5 seconds to initiate the daylight calibration
process. The LED flashes red to indicate that the calibration process is in progress;
this process takes 60 seconds. During the calibration process, the lights cycle on
and off. After the daylight calibration process is complete, the room enters Test
mode. Refer to “Test Mode” for details.
Test Mode
Test mode is used to verify that the settings stored during calibration are correct.
Changes to the amount of light in the space results in rapid light level adjustments.
NOTE: During normal operation, the light levels are adjusted slowly so that they
are not seen by the occupants in the room.
To enter Test mode, press and hold the button for 2 seconds. When in Test mode, the
LED flashes twice, pauses, then repeats. The device exits Test mode after 2 minutes.
To verify the daylight sensor settings, close the blinds or block the cover of the sensor
to reduce the amount of light in the space; the light level will increase. Open the blinds
or unblock the cover of the sensor to increase the amount of light in the space; the
light level will decrease.
Press and hold 2 sec.
Configure Keypads to Control Specific Loads
Keypads control all load controllers in the space (this is the default functionality). Use
Binding mode to change the load controllers that are bound (controlled) or not bound
(not controlled) by the keypad.
