How can I wire this without a "C" wire?

No. Learn how to run a C wire. Not hard. I've done it twice. Just need to buy thermostat wire and feed it don the wall behind the thermostat and run it to your furnace. Search UTube.

I suggest you download the manual and wire it per the instructions in the manual. Important! The Wi-Fi thermostat requires a C wire to operate. The C, or common, wire brings 24 VAC power to the thermostat. Many older mechanical or battery operated thermostats do not require a C wire. If you don't have a C wire, try: * Looking for an unused wire that is pushed into the wall. Connect that wire to C and check that it is connected to the 24 VAC common at your heating/cooling system. Note: Not all heating/cooling systems label the 24 VAC common C. Check your system manual or contact the manufacturer to find out which terminal is the 24 VAC common. Or, call a qualify service company and have them solve the problem.

Honeywell has a video showing you how to substitute G wire for C wire. https://www.youtube.com/watch?v=F05lIaNTMB4 Basically, G wire is for operating Fan only mode (no heat / cooling). You loose the ability to use FAN only to power this thing. You have to change wire on the back plate as well as in the A/C-Heater. I'm not very skilled, but I was able to do it, just following the video.

What I suggest is to look for the installation videos on the Honeywell Site, I remember they have one for your particular question.

If you're going to use the wires that come with the system you would have to splice. Or, you can buy extension cords that can add more length without splicing.

Nope! I went ahead and took the pig tails from the ac adapter and exposed the bare wire and made my own adapters. Or I supposed you could also do a terminal block and wire it all in that way.

the way I wired it was simply power and ground. I wired it to a relay first then a switch. its really basic

None ... Use an in-line signal amplifier somewhere in the middle (power is required at that point) and Power either end with the other output lead.

I'm no electrician so can't so if the polarity can be reversed by wiring. There is NO provision to allow reversing it by switch.

Sorry i cannot comment, i never had an issue with that. However, how do you change the wire?

Yes there is no other way for you to install this device without running the wire. Unfortunately, any wire longer than 60ft has been found to compromise the signal and make the audible sounds difficult to interpret. Stay at 60 ft or less preferably and be very careful not to damage or twist excessively, or kink the wire because it is not heavy duty and it will affect the performance.

You can wire it with 1 wire the other 2 spades I didn't wire because there were no directions in the box . I also grounded it

not to hard to wire. the gnd is - of 12 volt supply you need to run this. next to the gnd is 1v that's the + 12 volt, goes they. all the other connections are the relays out , all have normal open and close contacts. #1 is nc, #2 is common , #3 no, I think, and so on #4 no, #5 c,# 6 no relay 2, hope that helps. o and better to use a power supply that some what reg, from 11- 14 volts. bob

You'll have to add your own. I soldered a diode inline with one of the output wires.

You will need a switch and some wire. You can find wiring diagrams online for a basic switch wiring. I have 4 of these wired to 2 switches. They are great

Nope. But my experience with it is, its a hit or miss if you use it. I just wire mine directly.

Hi, I used a pre made wire kit that has a push button switch that I got off of amazon it works best

I dont see why you cant.just hook up the positive and negative wire and you should be good to go.the led lights draw hardly any power.they are great lights and good people to deal with. Good luck

This does not need a C wire. It uses two AA batteries. Honeywell (and others such as Trane) use a C wire on models that use WiFi or voice recognition or Z-wave so they can have a 24V connection. All thermostats use low voltage from the other connectors and typically use the batteries as a backup when there's no C wire. For this thermostat, you can take it off the wall, hold it in your hands and program it. You can't do that on models that don't use batteries. However, those other models can be programmed from a computer or phone app so it's less necessary.

I use a generic one, with interchangeable connection pins and variable voltage (but fixed 3A). Set it to 9V, center pin positive connection, and you're ready to go. I'm pretty sure you can find one here.
