Switched from GE Z-Wave dimmers, switches, and fan controls to the relatively new Lutron Caseta fan control. The fans are 3 speed pull chain (high, med, low). 4 if you count off. The fan runs normally on high on Caseta Fan Control. Any other setting and the fan turns too slow to be useful, even on MED HIGH. I think MED HIGH is about the same as LOW on the pull chain or the GE fan control. The older GE Z-Wave fan controls just had High/Med/Low and corresponded closely to the High/Med/Low on the pull chain. I'm stumped. The fans are circa 1990 (maybe older) Hunter fans.
