Hi there! I’m an hvac engineer :D turning it off as much as possible is the way to go for energy efficiency, but you do need to be aware of the humidity of the space. If you have humidity concerns, 78 is usually the unoccupied setpoint we go with. However!! You need to make sure that the controls are set to cooling and NOT to auto. Auto will make the heat turn on if it’s below 78 in the space. If the fan has separate controls, set the fan to auto tho

OH but for winter time, you should NOTTT turn it off. Set it back to heating 60F whenever the space is unoccupied. 65F if you have infiltration issues and certain parts of your home are colder than others. And keep all the sink cabinets open. You do NOT want to risk freezing and bursting a pipe.

Depending on how cold it gets in your area, you may even want to set your faucets to drip while you’re gone. To reconcile this with my love of environmentalism, I usually set large containers in the sink to catch the dripping water and then use it for plants or cleaning or something

I’m in Georgia which isn’t the humid-est in the country, but I have coworkers in Florida and everywhere else. We still recommend reducing the space temp setpoint, but to either install a humidity sensor to include in the controls or to be more conservative (85 is standard, 78 is conservative, but even a 1 degree release from your typical setpoint saves abt 3% of the hvac energy for the time the release lasts)
