Does a thermostat like this exist?

16 years ago

We are in TX which have fairly mild winter days where some day we even want the AC on and other days it goes from 80 to 30 in a few hours. I get really tired of having to switch between AC and heater as sometimes the AC needs to be on in the evening, but I'd want heat in the morning.

Soooo does a thermostat exist that does the following?

1. Allows me to never have to flip the switch between AC and Heater (propane furnace - forced air), but senses if below a certain temperature it will use heat and above a certain temperature it will be AC.

2. Allows me to program different settings for different times of the days like a regular programmable thermostat.

Anybody know of one if they exist that they would recommend?

Lyfia,

If you don't want to flip switches between heating and cooling, you want a thermostat with an "Auto
changeover" switch. You will also need a thermostat with an "outside air temperature sensor" option. Using a setting of 60 degrees (Outside) the thermostat decides if your in heating or cooling mode. You also want a programmable thermostat - Ca-Ching. Honeywell has a line of professional installation only thermostats that will do that and much more. Called "Honeywell Vision Series" they fully integrate remote indoor temp sensors, outdoor temp sensors, humidifiers, dehumidification, Ventilation air, UV lights, zone dampers, filter changes,...

Thanks,

Dan Martyn

YES. We use them all the time in commercial applications.
To set that up in a residential application will be more
money than you want to spend. I don't do residential but i
think there is a programable stat set to " auto " will do
that. check with the rest of the boys on this site. I think they can help you with what you need. i build my own.
Good luck. you are in good hands. Listen to the boys. They
know what is what. ( girls too ). I've worked with women
techs. They seem more thorough and patient than men. Who
knew. Soffie was one of the best techs i knew. she was only
24 when she got her ticket. Her husband made her quit.
Too bad. He was jealous of her. This is getting off topic.
good luck. I'm sure you will find help.

FWIW, When we built here ended up with about a 1500 foot gravel drive. The ground here is sand. Around here, there's something called "crusher run," which varies from 2" down to pea size. I spread that and then took a 4WD JD farm tractor and just went over and over using the tires as a roller. The big stuff went down and the smaller came up. Evened it up with a dozer blade on a GT. Couple of years later a added about two inches of regular sized gravel. Worked that in as previously described. It's held up fairly well, and yes, you do periodically have to add more gravel. In ten years have added gravel once. I plow snow with the GT and blade. The gravel has packed down and is pretty level and solid. I'd consider having the driveway graded, add more and larger gravel if what you have is small. To me, gravel driveways and snow throwers go together well. Mowing 3/4 of an acre and hauling and landscaping the balance would work well with a GT or even a hefty LT with cart. Yes, totally agree that compact 4WD would be the way to go, if price wasn't a consideration. With your budget you're looking at a used machine which could be a steal or you could be robbed. :-) Good luck, Ev

funny , these guys are recommending a high dollar solution. i simply bought a 7 day programmable tstat from lowes that has the auto feature. the way it works is you set your heat to maintain say 70, cool set to maintain 74. if it gets hotter than 74, the tstat kicks on the AC. cooler than 70 and it kicks on the heater. never had a problem with it. no exterior sensors needed, it goes by your indoor temps. i actually had mine set closer together, around 70H and 72Cool, but i like an even temp in the house.

oh, and it cost me around 80.00!

Thanks everybody!

davidandkasie - I'm guessing because they are used to commercial like they both mentioned and haven't seen the residential ones. So can you tell me what brand and model yours is as it sounds just like what I want.

Thermostats that automatically switch from heating to cooling (and back) are available from Honeywell.
Many require an 'always hot' wore from the furnace to run (no power stealing).
They run about $100+

Auto-switching thermostats have been around for years, even before electronics were common.

Carrier also makes an excellent t-stat that does all you want.
