    Motion Detector Only

    Greetings and thank you for taking time to read this.

    I have an instant hot water heater with an internal recirculation pump.

    It has a circuit that when low voltage is received will cause the recirc pump to activate.

    I am looking for a Motion only sensor, so that when someone enters the bathroom, the recirc pump will activate, and by the time they are done with business, the hot water will be there.

    Does anyone know if there is a motion only sensor, no switch?

    Thank you.

    Lutron does not offer that. Everything is tied to the 120v side.

    Yes, there are motion-only sensors available that can activate devices such as your recirculation pump without the need for a separate switch. These sensors are commonly referred to as "motion sensors" or "motion detectors." DWhen looking for a motion sensor for your specific application, take a look at this Drift Boss .
