I replaced an old fan speed control (one with a turning knob) into a Caseta and now it spins full speed on max position. If I slow it down from there one step it goes extremely slow (like 1 rev every second) and positions 1 and 2 give no speed. If I speed up from 1 to 3 the third step won't generate enough power to even slightly make it turn...Can I adjust the speed intervals?Thanx in advanceHans
