Hello -
With inspriation from Rex’s “ensuite” example as well as the examples found in the PLTS “getting started” PDF, I wanted to implement my own bathroom fan control.
This is just a half-bath (no need to remove humidity) so I’ve changed the logic a bit and wanted another set of eyes to see if this is correct.
- If the person is in the bathroom (turned the light on) for more than 3 minutes - Start the fan and let it run for 20 minutes.
- If the person was in the bathroom for more than 3 minutes (turned the light on but then left without turning the fan on) - Start the fan and let it run for 20 minutes.
- If the person is still in the bathroom after the first 3 minutes, reset the timer.
- If they turn the fan on manually - turn it off after 20 minutes.
My only issue is it will automatically fire the fan even if they don’t “need” it (if you catch my drift) so I’ll have to think of that a bit.
Does this look close?
