I've been reading over a similar thread -- https://forums.lutron.com/showthread...t=timer+button However this scenario is a little different so I wanted to see if anyone had some ideas if it's possible or not. Home has 3 bathrooms with a single, remote located, inline duct fan for the bathroom exhaust fans. This means when any bathroom turns on the remote fan, air is removed from all three at the same time. This nice thing is this occurs silently. So I need to to be able to have someone in any of the three bathroom turn the fan on, but I don't them to be able to turn it off. The fan needs to run for X number of minutes, then turn off. Let's say 30. So if someone goes into bathroom 1 and turns the fan one the 30 minute countdown would start. If someone else goes into bathroom two and presses the fan button then this would reset the 30 minute countdown. Since the fan operation will be silent in the bathroom it will not be possible for the person to know if they are turning on or off the fan. That's why I'm trying to make it where the button press only has the ability to turn it on, and a countdown will be responsible to turn it off. If the person presses the button on the way out thinking they are turning the fan off, having the countdown reset is not a problem or concern. Can something like this be implemented in Radio RA2?
