Fan speed controller issues

[Brandon137]

Hi guys I just bought a vortex vmf600 and hooked it up to my fan speed controller and the fan will only run on high speed during start up. If I try to start fan on low speed it won't start high speed is to fast during normal operation. I can turn the speed down once it is going however I'm concerned that during a power outage when the power comes back on the fan won't restart automatically. Is there a plug and play fan speed controller that anyone would recommend for this fan that starts at full power?

That feature wasn't part of the design of your setup - I used that tech 10 years ago. I upgraded to digital controls from AC Infinity to get better control of my environment.
