I have Ecobee 3 Lite about $130 on Amazon. Easy to install, works well and has humidistat functionality. I also have one in our condo in MI.

I have installed many wifi thermostats, and I will agree 100 percent with the new carrier heat pump systems installed in the newer homes, you need to remove the junction block connection between the old thermostat and the ac unit , or you will burn out the transformer, lesson learned.This was the most complicated install. I definitely would have Munns install.

Munn’s installed a Nest for me. I did it because I wanted something easy to program and to keep track if I am away from home. It has been great. It cost $374 for the Nest, installed with a 5 year warranty. I'm very happy with it. The Munn's installer was very professional and did a good job.

Munns installed WiFi Honeywell in my TV home. Works great and has a dehumidify away mode that lets you set the max humidity in your home when your up north over the summer. Humidity in my house never went above 60% over the summer.

We prefer our old fashioned thermostat, no wifi, wireless, or anything else that can go bad or breach our data. Our motto is KISS, Keep it simple, stupid.

Could you tell me how many wires you need going to the thermostat ?

IIRC ours had 4 or 5. We have a Carrier Heat Pump here (~9 years old) and whatever wires are there are fine. You can even connect these to a 3 wire 30 year old system (we did that way back when). It does have to have a "C" wire which caries the 24V voltage to keep it on but every system here surely does that and even if it didn't you can install a power block. Just take a photo of existing wires as they are hooked up before removing old T-Stat. If you can change a wall switch you can install one of these. Just follow the setup. They make it ALMOST fool proof. If you have minimal handy-man capabilities you can save yourself the $200++ they charge to install them. Just turn off the power so you don't short it out. 24VAC can't hurt you but it can the T-stat.

We have a Career Infinity touch (wifi) installed by Munn's when our new system was installed. It loses wifi from time to time. Munn;s service guy said that it can't be replaced by a Nest or Ecobee.

Not that easy if you have a Carrier Edge thermostat. There is a control box by the blower in the garage that complicates everything. I have seen internet threads implying you need a 7 wire feed to the thermostat.

Bought Ecobee 3 on Amazon for $approx $159. Interacts with Alexa. Michael of Good Guys HVAC installed (352) 805-0035. He's a Villager. His cost $95

Who installed this for you?

We just had a new A/C unit installed by Munn's - very professional, fast and efficient - the new unit is 3.5 ton, SEER-16, with an Ecobee thermostat - it's awesome, easy to set/use/change settings on my phone, easy to use in the house (you can just talk to it and it will set temps, etc.). Been in a month and ZERO issues. Really easy to use and works well, and again, kudos to Munn's - they were great!

It seems that's because they basically install the "thermostat guts" at the blower unit and just "remote" the display box/temp sensor with 2-wires. The rest of the wires should be there in the wall unattached.

You need to bypass the control module and get rid of it. Then simply connect the Nest's Rh,Y1,W1,C,G connectors to the RYWCG terminals on the furnace.

Great! to make sure I understand. Do I remove the current wiring from the furnace, and take the wires that are currently plugged into the control module and plug them into the furnace?

Correct. Remove the current wires between the control module and furnace. Then move the cable currently connecting the thermostat (old red/black) and use 5 of the wires to connect to the furnace. Keep the other cable with two wires (red/white) on Y and C connected as that feeds the outside a/c compressor.

It looks like there are more than 7 wires in my edge, besides the jumper wire.

OAT and SRTN are for the Outdoor air temperature sensor. The Ecobee and Nest WiFI thermostats use weather stations so it's unnecessary. Not sure how the Honeywell uses that, probably the same way.
