When your CentraLite Azela Lamp Module (4256050-ZHAC) has got a problem and is not working, then
Check whether you are receiving power 120V from a 60 Hz AC transformer.
Then see whether the load is controlled.
If so, the load should not exceed 300W, as its total capacity is 300W.
When the load functions with the lamp module but not with ZigBee network it means that you have to reinstall the device again.
