Can you help me find a replacement thermostat? Having trouble!


anything over 1 degree will often pull the aux heat on...it all depends on the stat.

Ohhh.. I did not know that. So if I turn the heat down to say, 68 at night it turns on the aux heat?! That seems silly. What am I supposed to do, turn it to one temp for the whole winter and deal with it as is?

yes, heat pumps are best to set it and forget it. The only other thing you can do is to get a sophisticated thermostat that can lock out aux heat above a set outside temp.

Having a great room with a large amount of windows also defeats the purpose of getting a system to work its best. Also as for Winter, setting down to 69/71 also defeats the purpose of having a heat pump system. It does not get that cool in the Pan handle, compared to say the Midwest. A lot is in the mind.

I would say as for your husband working out, doing it in the early morning with the sun rising, yes it will make you work harder, so I would say that he may want to find a different location for using say a treadmill, than in a large convection oven. Turning down the thermostat not only makes the system work harder, but also it takes longer for that large space to cool down, compared to the rest of the house.

Ugh. Hopefully I can just get him to move his workouts to the "office". This is where my elliptical is, and the rest of our workout stuff. There's already a tv for him!
Thanks all.. I didn't realize these systems were so finicky. What do you suggest we have the temp set at in the winter if it becomes necessary? Maybe 73?
As for the thermostat- If anything, I'll probably stick with the Honeywell 7500 because it's much like the one we have where it has no swing, has set temp and room temp, clock, works with my system, and has programming. I think the programming will make my life easier even if I get hubby to move into a different room for his workouts.
....and I'll keep the one we replace (if we replace it) in case our bill goes sky high with the new one. If that happens we can go back to the basic one and start over.

It really depends on what the outside temp is. If it regularly stays in the high sixties during Winter, I would probably set the thermostat in the mid 70's, say around 74, and utilize outside air as long as it is not high humidity outside. It is more of personal preference, and depending on inside humidity, will depend on what you set the thermostat at. I normally keep my inside humidity between 45-55, and temp during Winter around 69, Summer around 72. My dad keeps his home temp around 74, in the same town.

Everyone's temp settings are always going to be different and not every two people are going to think the inside temp is the same. If you were to ask someone walking into your home what they think the air temp is in your home, they will most likely either state that it is cooler, warmer, or about the same as the thermostat, due to perception.

Well this one has programming up to 4 different periods of the day. It also has a nice big screen that can be left on at night as a nightlight. It's for heatpump and with emergency heat. Honeywell tstat are excellent products. You can also hook up a outdoor sensor for defrost purpose.

Question RE: Cool/Heat/Aux.. if the thermostat had a feature to automatically change from cool to heat if the temp drops below set, would that stop the aux heat from coming on?

The Honeywell RTH 7600 and RTH 7500 both have this feature, my indoor/set temp, compatible with heat pump and multi stage systems, back light, and programming.. and are in my price range.

Yes, yes. Very nice features. I do not need a night light, but just a backlight for when I change the temp before bed. Also, requires professional install, so this $85 tstat will wind up costing me a whole lot more in the end

You say it's for heatpump and emergency heat.. I believe the Honeywell RTH 7600 and RTH 7500 are also for such. Am I correct, or incorrect? It says they are for heatpump. (doesn't specifically say emergency heat though, in the basic features on Honeywell's site). Both also have a feature to turn from cool to heat or heat to cool as needed for temp fluctuations.

Darn. So what is the difference between one that does not state it's for heat pump systems vs. one that states it in the specifications? I will make sure I get one that states it in the specifications, which the Honeywells I mentioned do.

Lol, well i don't know if you would call it as a backlight or nightlight. But how it functions is it will slightly stay lit up and not 100% dim. So you can see it when your in some dark hallway. And when you press on the screen it will light up. This thermostat is the visionpro 8000 series. So it's going to have the features of the 7500 and 7600 plus more. You should compare all the specs before you buy and see the overall price different. As for the wiring up the thermostat. Its going to be the same for either one. You can wire up yourself and we can help you if you like. Its pretty straight forward. If you got anymore questions on the specs then keep asking here. We'll try to help you out.

I saw the RTH8500D on Honeywell's site. It looks the same as the pro one.. but says DIY versus Pro install. Otherwise it's a 5yr vs 1yr warranty, and the 8000 can display outside conditions. Not sure I need that feature, being realistic. Saw the 8500D online for $86 or so.

I am not sure I'd want a touch screen. I've heard they can fail much more frequently than standard digital ones. If it fails I have to replace the whole unit. The digital screens on the more basic ones are less likely to go out. Also worried about them being finicky to our touch which would just frustrate me.

At this point I am very, very confused. You've all provided great information but I'm reading that these newer tstats that are "precise within +1/-1 degree can cause your unit to run too frequently, over time causing damage to it. Specifically one post about the 7500 says it's set to kick on when the room temp drops .5 degrees. That would make any system run nearly constantly, I'd think! There's no way to override it. Apparently on the contractor models you can make it up to 3 degrees somehow? Is this true?
The Honeywells do not have swing, which could alleviate this issue. However, swing may be bad for me since I think I'd either be too hot or cold by the time the tstat came back on based upon the swing.
Most of these Honeywells have built in "compressor protection" that supposedly stops your compressor from running again shortly after it turns off. Since I have no idea what my current tstat does, or its accuracy, I don't know if my system is already doing this.

If these newer, more precise tstats can cause damage, why would they make them? And I am even more confused because of having a heat pump. I am worried anything I buy is going to mess that up. Heck, the one I have is probably already turning on emerg. heat and I don't even know it. I think at this point, I need you experts to let me know if these newer ones will indeed cause the damage I am reading about.. and what I need for my heat pump. The last thing I want to do is cause damage simply because I am trying to add a little convenience. :\

If the 8500 or 8000 is what I need to protect my system, then so be it.. but that's the only reason I'd buy it. It's a huge panel and expensive. If the less expensive options won't cause damage, I'd rather go that route.

Break down and get a Honeywell IAQ thermostat, and optional outdoor sensor.
