Electronic Thermostats

[sixpak]

I have a question about thermostats. I am looking for a residential thermostat that I can program for certain temperatures at different times and different days. So far those are easy to find. But, I also want that thermostat to be able to automatically switch between heat and A/C like some of the commercial controls. Is there anything out there like that for residential? I have a standard updraft furnace with A/C.

I personally find the 9700i is the most reliable.
just my opion.

I agree the honeywell vision pro is one of the best t-stats out right now. You can set it up for auto change over you csn also install an outdoor sensor with it. The t- stat is very user friendly. There are some stats out there that are more complicated then your home computer. very good t-stat for the money. good luck.

this feature attracted me to Robertshaw (9915i)...that and a filter monitor that can be set on actual hours run, not only based on days.

So the function of the thermostat being able to switch from heat to A/C is called "auto-changeover", right??

Thanks for the input, guys

FWIW, my car has this feature and I find it annoying as hell. I guess if the system could use an outdoor sensor to be sure that it really needs to changeover it would work better? There is nothing more annoying than the blast of cold air in your face just because the car overheated itself.

Your mileage may vary.

White Rodgers big blue. Simple to use. All of my customers have loved it.

vison pro 8000!!! love it or hate it, it is the best T-stat out right now. The filter alert is set on actuall days of run time, ie. 24hrs in a day, if the furnace runs 6 hrs a day it will take 4 days to make it go 24hrs.

[sadlier]

VisionPro 8000 is my favorite. It can be set for either programmable or nonprogrammable; It has a 'recirc' option in which it will periodically turn the fan on to circulate the air in the house; Programming the thermostat is relatively easy compared to others; It can be battery backed (comes with batteries) so that it will continue to operate even with power off (such as when removing the furnace door); Harder to accidentally change the programming than the White-Rodgers thermostat; And certain models will display outdoor temperature and indoor humidity.

I agree with wpg hvac on the Invensys stats (must be a manitoba thing) They seem to be the most reliable and the most user friendly choice i have seen. They are menu driven (they pretty much walk you through the programming)

The Vision Pro 8000 and 9000 series thermostats are hands down the best thermostats on the market for controlling heat pumps and multistage heating and/or cooling equipment. The P+I control is worlds better than the logic other thermostats use to control on/off cycles and staging.

[bokenrosie]

so these work with the Mod 90+ instead of the custom contour thingy? do they have remote sensing like the custom contour?

[elkhvac]

the VisionPro is very reliable. We have installed hundreds of them and have only had two failures.

[mark beiser]

On the Mod, you need to use their special thermostat to make full use of the furnace.

[allstar08]

the york mod 90 and the coleman mod 90, do not need special stats, so the pro 8000 would work awesome.

I have to wonder about anyone who actually wants one of these. If it were my house I'd leave the wondows open on a day like that or not use any heating or air conditioning. Is there something here that I'm just not getting?

Mark is correct - the 9000 has more features & benefits and more compatability than any other product I've seen.

I'm a newbe here. I'm interested in purchasing the WR 1F97-1277 t-stat, but I'm wondering how the remote outdooor sensor can be used (part F145-1378). I understand that you can somehow program the t-stat to calculate a more suitable temperature by weighing out the remote "outdoor temp" with the "indoor temp".

What I'm most interested in is using the remote outdoor sensor to ONLY display the "outdoor temp" on my display at all times. (I don't need it to do any kind of calculation, etc. for my t-stat)

Thanks for your help!

Hi Bmarshal8,

I am sure there is someone here you can guide you on your search for the remote sensor but if it is only to show outside temp you might want to check out the cool xmas gift I received last week. It is temperature plus 5 day weather and works off radio waves.

Good Luck with your search

[bmarshall8]

Bokenrosie, Thanks for the great idea. That device looks very cool! I will definitely have to think about that as an alternative!...

I'd still love to find out if there is a way to statically display the Outdoor Temp on the White Rodgers 90 Series Blue t-stat.

Thanks!

Right now I have a CT3611 thermostat that works, but the features are lacking. I noticed on one of the VisionPro 8000 models there is dehumidification control. To use this feature does my system need to have anything special or is this just another way the thermostat can control the temp of the house? Thanks

[bokenrosie]

I spoke to an engineer at Rheem/Ruud yesterday afternoon. It seems the new thermostat they are selling with the Mod 90 furnaces does not do the six remote sensors that the original unit did. The UHC-TST401MDMS can use one remote sensor. That can either sense a remote location or outside temp, but not both.

One particularly cool feature about the remote sensing is that you can use a weighted average to analyze the sensor. You can change for the set period on your schedule. Practically speaking, it would seem you can tell the thermostat, located on first floor to pay less attention to the remote sensor (located in second floor bedroom) during the day and more attention to it at night (when you would likely want it to be closer to your setpoint in the bedrooms).

I'm sold. I ordered the Mod 90 Ruud, a Humidifier, and this Super Thermostat this morning. They are installing on Monday. Yeah!

I have used enerstat (now it robertshaw 300 series) for years. It is the best stat on the market. (IMO) :D

They look like nice Thermostats. I read here that Ruud Mod 90+ will only function as designed with the White-Rodgers unit. Am I getting it wrong?

I don't have any information on that!
