Panasonic Fv-Wcd02 Whisper Control 4 Function Light Switch - White

How it works: The top button operates the light, the bottom button is for the fan or heater. The unit operates with 2 timers for the fan. There is a countdown timer you can set anywhere from 5-60 minutes. Then there's the Minutes Per Hour timer that will allow you to set anywhere from 0-60 minutes and it runs your fan for a set time every hour to expel stale air. The MPH timer also sees when you've used the countdown timer and knows not to run the fan for a while if you've already done it. The unit can be mounted single-gang or multi-gang. Must use #14 or #12 wire with hot/neutral/ground. There is a tool that comes with it that must be used to remove the cover over the timers so hope you don't lose the tool. The timer feels very cheap to the touch, not the sturdy plastic of my other switches. I hope it holds up. Model FV-WCD02 does NOT look like the photo you see here. There are 2 on/off buttons with a thin blank plate in-between. Try to Google it somewhere else to find the exact photo. I had a hard time finding detailed information about this switch so I hope this review helps somebody else.
