Test the Loads
To verify system wiring, the loads can be tested before setting up the Zūm space. Press the TEST
button to toggle the connected loads on and off. Press and hold the TEST button to cycle dim
the connected loads.
Factory Reset
A factory reset should be performed when the ZUMLINK-EXP-16A-DIMU is removed from the
network or to remove the configuration settings from the device. The ZUMLINK-EXP-16A-DIMU
must also be factory reset if it is being moved to a different system.
NOTE: New-in-box devices do not need to be factory reset before joining a system.
To factory reset the ZUMLINK-EXP-16A-DIMU, press and hold the TEST button until the TEST
LED lights (about 10 seconds), and then release the button. The TEST LED and the connected
load output turn on to indicate that the factory reset procedure is complete.
