I currently have a Honeywell XT 302C programable thermostat installed in 1998. I do not see a terminal connection labeled "C". How do I find the"C"

Hopefully this will help you it did to me, http://smartthermostatguide.com/thermostat-c-wire-explained/

More information is neededsuch as what system do you have. Is it just a furnace or does it incorporate central air. And what connections were on the old thermostat (w,r,y,g)?

Here is a manual--it looks like there is no "C" terminal. here is a link to the manual. http://www.comfortsite.com/resources/literature/pdf/18-hd25d7-5.pdf

First thing to check is if you have 4 or 5 wires going to your old thermostat. If you only have 4, there are some work arounds, but you will most likely need to do a new run with 18/5 wire Southwire 64169622 5 Conductor 18/5 Thermostat Wire, 18-Gauge Solid Copper Class 2 Power-Limited Circuit Cable, 50-Feet, Brown

There should have been a manual that came with it. But on the internet type in hw to program whatever tempature controller you got and hit search.

This thermostat has to be purchased from and installed by a dealer. Otherwise, the warranty does not apply !!! beware of this.According to Honeywell, the features on both models are the same, except for the 5 year and 1 year warranties

After a lot of research I finally found the right remote thermostat for this unit. The Honeywell TL8230 programmable thermostat. It is a very nice thermostat but it will require some re-wiring of the New Air G73 unit. The good news is it works the way I expected it to be.

No. You just have to make sure the connectors to your existing thermostat are compatible with this one. You can look at the one you have now and see if it is not by the online compatibility. I did not. And mine was not compatible.

smallappliance.com I ordered a new digital control unit last spring. Great service!!! Use the small reference number on the very bottom of the silver tag located on the rear of heating unit. I was trying for over a year using the series number F-36C, and getting nowhere. The folks at smallappliance straightened me out on the phone. It cost about $70.00, but got a 1st time customer discount & free shipping. I think I wound up spending about $60.00. Hope this helps.

Here ya go. Hook up the red & green wires for heat. I'm assuming you don't have A/C hooked to your thermostat.http://www.ehow.com/how_5552276_wire-honeywell-thermostat.html

Not for this model. All you need is Wi-Fi. The thermostat connects directly to your Wi-Fi router / access point. When you do the initial setup you choose the SSID of the Wi-Fi network you want to connect to and enter in the password. From there it connects directly to Honeywell and you can manage it from their website or phone app. Some people have noted issues with it disconnecting from the network, but if you force WPA2 that should resolve it.

This thermostat is a z-wave device circa 2010. The Honeywell Lynx 5200 is probably based on a newer z-wave revision, but it should be backwards compatible with most z-wave devices. I had this thermostat connected to a mi casa verde controller and it worked as expected.

That description means the "USNAP" transceiver; it is a radio module, Wifi protocols, that is snapped into the thermostat and communicates to the router. This has nothing to do with the C-Wire; this is ONLY the radio (wifi) communication with your router. The C-wire is 24V that you need to power the thermostat. This can come directly via this C wire from your furnace (my furnace had a "live" 24V C terminal) or a separate transformer. In my case, the stat was on the first floor, the furnace right below; I pulled new 6-conductor wire using the old 4-conductor as a "fishing line", and this allowed me to use the furnace's built in voltage and no additional transformer was necessary. If you can't do that, and you only have 4 wires, and pulling new wire isn't possible, then you will need a separate transformer for power to this unit. The reason for this is simple: a normal thermostat with 4 or 5 wires does not need power; these lines are switch lines. The only power your stat needs is from batteries. Wifi, however, is a radio transmitter that need constant power, more than batteries can supply.

I think they have the description wrong, I googled 80 series blue and it is a different thermostat, also my new thermostat is b@w display!The thermostat that I replaced had different wiring though, it was the same but it did have an extra jumper wire, I had to study it for awhile to figure it out but it worked when I hooked it up, my old one was like 20 years old so I think they upgraded it!

Do you know how the old thermostat was connected to the wires is very important to observe the terminal labels when removing an old thermostat because sometimes the existing wire color codes are not proper.

http://host0158.csmhosting.com/Documents/Thermostats/Installation/I-5000-512.pdf I have attached a link to the th106/u user manual. It has a dip switch to change from C to F. It also has a couple other settings you may want to check.

Seems like the sensors and gateway link to the Redlink Thermostat. You push a button on the sensor, or gateway, and the Redlink Thermostat connects to it. So I think you need a thermostat that has Redlink functionality, but I'm not 100% sure.

If the TH942C1004 that Amazon has is the same model as the Thermostat you have, it should fir on your sub-base. Honeywell recommends that you replace the sub-base with the thermostat. You can place the thermostat on the existing sub-base to verify it works. If it does't, there may be a problem with the existing sub-base; therefore you will have to change it.

There are multiple wiring configurations included in the unit's instruction manual, I would suggest searching the web for an electronic version and downloading it to see if it includes everything you need, or contacting Honeywell directly.
