Please advise how can we install UT-305-3 as surface mount installation. What accessories do we need for surface mount installation.

Asked by: Mohammed Kazim

Wattstopper does not currently offer a surface mount kit for the UT-305.

The sensitivity control does not seem to be working correctly. Full CCW works but as you turn the control CW, it seems to not work.This unit controls the lights and a exhaust fan.The panel that the unit is on has some vibration from the exhaust fan nearby

Asked by: Leo Schaaf

If the unit is vibrating, I suspect that is the problem. Once you take the sensor out of service mode, the sensor is again active (at varying degrees of sensitivity depending upon how far CW you adjust the trim pot), but due to the vibration, the sensor sees everything moving and will hold the lights ON.
