I agree with Timex's post on using the low speed for noise reduction. I have since installed a Luxpro digital on my Windjammer with an spdt switch. I bought the switch from Radio shack and installed it on bottom of my thermostat out of sight but easy to reach with my index finger. Don't bother unless you just want a longer project on the switch.
