Control-IT Posted July 31, 2019 Share Posted July 31, 2019 Looking to the best way to automate bathroom fans. I did some programming when they turned the light on the fan turns on and then when the light went off I delayed the 5 minutes and then the fan shuts off. What if they don't turn off the light at all but just walk out? Whats the best way to do this delayed shut off so they don't have fans running all the time?

Cbell Posted July 31, 2019 Share Posted July 31, 2019 If you have the occupancy sensor with Humidity option you can check the Humidity when someone comes into the room. Check the status of the Light / Fan. Check the occupancy of the room.Check humidity when the value changes setting a threshold as you trigger for on verses off.You can use occupancy Plus humidity value to decidewhen to turn the fan on / off.Sent from my LM-V350 using Tapatalk Quote Link to comment Share on other sites More sharing options...
ILoveC4 Posted July 31, 2019 Share Posted July 31, 2019 After X time turn the light off, and have the fan turn off then. If they turn off the light by pushing the button and the fan is on, wait 5 minutes then turn off the fan. Seems pretty straightforward and doesn't require buying a $200 (!) motion sensor with humidity sensor. Quote Link to comment Share on other sites More sharing options...

It also works as a timer. Quote Link to comment Share on other sites More sharing options...
Cbell Posted July 31, 2019 Share Posted July 31, 2019 Very true. However... It depends on what you want to achieve. By putting an arbitrary timer you run the risk of prematurely shutting the fan off before it has properly vented the bathroom. Or... In some cases, like in my home, someone is showering during the day and doesn't put the fan on. But like you said, it saves you 200.00 but you loose functionality.Sent from my LM-V350 using Tapatalk Quote Link to comment Share on other sites More sharing options...

RAV Posted August 1, 2019 Share Posted August 1, 2019 Set a max run time maybe an option for both the light and the fan. Quote Link to comment Share on other sites More sharing options...
ejn1 Posted August 2, 2019 Share Posted August 2, 2019 I assume folks are using a standard c4 light switch to control the bathroom fan? Always wondered if the fan load was in spec of the light switch? Quote Link to comment Share on other sites More sharing options...

Not necessarily override programming but if you have programming turning on the fan then yes it will still come on but will always turn off if you select the auto off feature setting in the driver Quote Link to comment Share on other sites More sharing options...
