Installed one of these several months ago, and the "training" of the switch regarding the maximum ambient level at which to energize the light dialed in after maybe a dozen taps on the manual off button. Lately, it randomly turns on the light even though another rather bright nearby fixture is already on. And, more importantly, a recently installed second unit, same model, will not train at all. Only at maximum daylight (sunlight beaming into the area), will switching on the light be inhibited. If I went to something like an MSCL-OP153MH switch, would I still have the same sensing and training issues, or would these functions be, um . . functional, in the OP153MH series ?
