What causes the LMRC-101 to beep?

Asked by: Mike

The LMRC-101, like all other DLM devices, is not designed to produce any audible beeps or sounds. If a beeping noise is heard, it is not coming from the LMRC-101 or any other Wattstopper device. The source of the sound is likely an unrelated piece of equipment in the surrounding environment. We recommend checking nearby devices that may have audible alerts or notifications.

can this controller be put in a manual mode to over ride the motion sensor?

Asked by: royflex

Hi Roy, The sensor can be overridden directly at the sensor itself. Pressing the "Feature" button until you see "T-Delay" then using the down button to drop the time delay down past 1 minute, you will see "Over". Leave it there and the sensor will be completely overridden until you set it back. If you would like for someone to walk you through the process, please call 1-800-879-8585 Options 1.
