would anyone dare recommend a wifi stat that won't break the bank

raylo32 09-12-2013 09:35 AM

I have had a 3M Filtrete 3M50 wifi stat for a couple of years. Works fine for me (others here have had some issues)and cost about 100$. Easy to use mobile app. My only rap on it is that the stat itself isn't super user friendly so it might not be the best choice if you have other family that will need to operate it.

Honeywell has a new line of wifi (they also have a separate proprietary Redlink wireless line) that uses the standard intuitive Honeywell stat designs that many of us are familiar with. Very easy to operate the stat. A little more $$ than the 3M50, though. I haven't tried one of these Honeywell wifi versions myself yet but I assume that mobile and computer apps will also be intuitive.

I may upgrade my setup to Honeywell just for the better usability even though my 3M50 is still working fine.

One other thing depending on what kind of stat you have now.... You probably have a unit that is strictly battery powered. The wifi stats need to be connected to the 24vac transformer in your furnace/air/handler to provide power for the wifi radio (they also have batteries for backup). You do this by connecting a wire to the "c" terminal on both ends. You should have an extra wire in your t-stat wire bundle, else you wil need to run one.

raylo- how would you compare that one with a rth 8580wf

raylo32 09-13-2013 08:46 AM

I don't know what that is. Do you mean the 9580wf smart thermostat? If so, I don't like that one personally. It is supposed to be like the Nest and has a learning function then purports to self program itself to your patterns. I'd rather have control over my own system and be able to set and understand the programming schedule.

hvactech126 09-13-2013 08:54 AM

The rth8580 is the retail version of the th8320... mostly the same but some differences. The 9580 is not at all like the nest.... it will not auto learn your patterns and program itself. It will learn how your home heats and cools and turn on your HVAC equipment early to meet the setpoint at the time you have it programmed to be at said temp. It is really a marketing ploy as almost all hw programmable thermostats have this function... the big selling point on the 9580 is the color touch screen and easier setup... otherwise it is a typical programmable thermostat with WiFi access. The 9580 doesn't have a proximity sensor and therefore has no way to know if someone is home or not.

ty gentlemen-so could a diyer intsall the 8320 with no problem since it is not the retail version

raylo32 09-13-2013 10:14 AM

Should be no difference. Look at the wire colors and terminal letters and connect the new one up the same way... except you may not have the c wire on your current one and you need to connect that on the new one, also on the furnace control board c terminal end. Alternatively you can use an external 24vac transformer plugged in near the stat but that is sort of a kludge.

I have a "c" from the furnace to a humidistat,that is no longer used, that I plan to jump from for the new stat

I had a nest thermostat for almost a year. I really liked that it was so easy to use, and the learning ability worked well for me and my schedule. 6 months ago I replaced the hvac system to one with a variable speed blower. The nest would not work properly with that unit and had to be replaced.

I also have the nest, but a basic natural gas/steam heating system. It is really great for me and my fiance because occasionally we work from home and it's super easy to adjust the temp when trying to drop.

It took me about 5 minutes to install the nest, I just took a picture of the old wiring and when I installed the nest, I followed the same connections.

Plus the User Interface for the nest is real easy and we never had a problem with it.
