Multiplus II temperature sensor missing from package

I got my Multiplus II a few months ago and it did not include a temperature sensor at all. Just the unit pretty well packed but no external sensor of any sort.

I’m getting alarms when the case is only at 100F which seems very low for there to be an “alarm”

Very odd. Contact your supplier.

Internal temps can be affected by installation as well. (Orientation, enclosure, loose connection, etc) So really more information is needed here. And probably your own thread.
