I have 3 occupancy sensors that do seem to shut off the lights when unoccupied. I see the red and green light flickering meaning we clearly have power.

Asked by: Serge St Pierre
The red and green are activity LEDs for the sensors, if the LEDs continue to flash when you stand still, then the sensor is likely false tripping. I suggest to start with placement, assure all sensors are 5-6' away from air supplies this is common to false trip the sensors causing lights to either stay ON or OFF. If more assistance is needed, please call our Technical Support Team 1-800-879-8585

Is there a diagram that shows how a LVSW-104 connects to a LC8 and a DT-300 and so on? This is beyond frustrating trying to find a diagram that shows how this system is actually wired. Makes one want to use Leviton!!!

Asked by: DennisB
Yes, please refer to page 15 and 16 of the LC8 User Manual which shows connectivity for switches and sensors . The LVSW-104 contains 4 separate 2 Wire Momentary switches, so you will follow the diagram for '2-Wire Momentary Push Button' connections. The LC8 User Guide can be found here: https://www.legrand.us/lighting-controls-and-systems/lighting-control-panels/stand-alone-panels/lc8-lighting-control-panel-includes-lcps-120-277y/p/lc8-120-277 If you need additional assistance, please call our Technical Support department at 800-879-8585,

I would like to use this occupancy sensor only to control HVAC via the external contact not lighting. Is it possible to connect 24V power directly to the sensor and avoid using the battery pack?

Asked by: Joe
Yes, the sensor can be powered via another 24V source, but it there's any question as to the voltage level or stability of the external source, we would recommend using one of our power packs.

I have an existing system with BT-150 power packs, DT-300 Ceiling Mount Occ Sensors, and LP8 Panel. I am looking to add dimming wall switches to this system. What part numbers do I need? Can this be a wireless switch programmed to the sensor?

I want to use the internal isolated (DT300) relay output 24VAC/Vto signal occupancy vs non-occupancy to my controller. however, the controller has 0-5, 0-10 VDC, 4-20mA, and dry contact inputs.please let me know how to match output to controller input?

Asked by: CuriousMatt
The isolated relay on the DT-300 is a dry contact which I would recommend you to use unless your controller need voltage. If you are needing more It would be best to contact Wattstopper Tech Support at 1-800-879-8585 option#1 for us to gather more information to help resolve your issue.
