Can anyone solve the mystery of the dial in my Master bath that has baffled me since purchasing the house?

So, we’ve got this strange dial in the Master bath that’s been a total mystery to us ever since we moved in. Any ideas on what it could possibly be for?
Looks like some type of timer, maybe? 🤷🏼♀️
It seems to be a dial for a heat lamp or light.
Do you need a timer for the heat lamp? Have you seen a colored bulb in a ceiling fixture?
Most likely a full house ventilation fan located in the attic. These fans help bring fresh air back into the home… maybe!
This is what I came to say! Have the same!
Seems like a light timer that might not be connected anymore. If you turn it and nothing happens, that could be why.
Destiny dial, anyone?
Hey, the more you push in the dips, the longer it will stay on.
Seems to me like it’s a timer for a heat lamp
Tracy really got it right – that’s a timer for a ventilation fan

It’s probably a timer for an exhaust fan or heat lamp, but it could also be for a whole house attic fan or something else.
My parents have a timer just like that in their bathroom. It’s for a heat lamp.
I think I prefer using a heat lamp instead of a fan. I assume the bottom slider lets you select between completely off, fully on (sunny), or timer setting
Timer function
Fan timer option
This is a timer for the bath fan or auxiliary heater. It has three positions: off, on, and timer. Slide the tabs in for “on” and out for “off”, or vice versa 😉
For a 15 amp timer. Rotating the dial around should activate the micro switch to send power at the designated time. If not, your bulbs are probably burnt out.
Lower switch also determines full off/on or timer.
Definitely a sundial. 😂
What other method is there to operate the whole house fan?
Our jacuzzi is equipped with a timer function for the inline heater.
Moving from left to right, the switch can be in one of three positions: Always off, always on, or timer mode. When the switch is pushed in on the white setting, it indicates that the device is running, while the other settings keep it in the off position.
Is that a ventilation fan? We had a similar dial in our older house.
It’s actually a timer switch. (My husband works as an electrician). We have one for our outdoor Christmas lights. If it’s programmed correctly, it appears that something is not operating from 6am to 11am, otherwise, it’s working. The bottom bar functions as the switch (from left to right) for full off, full on, and timer mode. It’s quite unusual to have this type of timer switch in the bathroom. Do you know what it’s controlling? Perhaps a heated floor, a fan (such as an attic fan), or a jacuzzi heater? There might be a more suitable switch available that we can install for you. Best of luck!
Timer switch for underfloor heating?
Have you ever considered installing a whole house fan?
I once purchased a hot water heater that came with a timer to switch it on and off, mostly off during the early hours of the day. Supposedly to conserve energy, but it ended up just causing some chilly showers until I got rid of it.
