Does it require special thermostat wire or i can connect with any wire?

Well, I used 18-2 thermostat wire since I wanted the absolute best precision from this sensor. This type of thermostat wire is not very expensive. I would recommend it, especially if it will be long and coming close to other electrical wires (as in most homes). Definitely don't use phone wire I think, you'd have too much impedance loss.

Since it is a resistive element, good copper wire can be used. The longer the wire, or the smaller the wire, the higher it's resistance value. I don't recall the wire gauge I used, but for accuracy, I wouldn't recommend lower than 18AWG. Remember; the unit cannot be more than 200 feet from the thermostat.

I think that it only requires 2 conductors, so thermostat wire would definitely be fine.

Jeff is correct. Only two wires (conductors) are needed. If you have thermostat wire with more than two conductors, no problem, just use two of them and ignore the rest.

For a WiFi thermostat, the 24v pair of wires connect to C and RH (or R) according to this video. http://www.youtube.com/watch?v=8a_f2_iAW1U

I just used the wires supplied from the unit itself. Simple 3 wire connection. There are no additional connections or additional wire needed. Simple instructions will show you where to connect them. Should you have any issues, please let me know. You will be very happy with this unit. I am. Ron, Mesa, AZPS remember to shut off A/C unit breaker before attempting to install.

I really doubt that you can hard wire this unit with an external thermostat. But why do that? The remote already has the built-in thermostat. So there's no need to hard wire if it comes with a transmitter and a receiver. Just make sure you purchase the model that comes with this.

No, you cannot connect directly to the thermostat. You have to create an account and connect via the third party server. However, the advantage here is the server will send you alerts if it loses connectivity with the thermostat (if you want it to).

It needs the C-wire. In my case the A/C unit had the connection and I could use the existing wire as a pull string to run the new one. I bought this unit specifically because of it's width. The battery powered units I could find would not fit between the two door jams where my old thermastat was.

It would be nice to have an aswer to this question. I could imagine a device that works without a third-party web site, where you connect directly to the thermostat, but I would be surprised if this device had that ability. If someone can verify that it does, I will buy one, otherwise I'm going to wait.

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)?

You'll need the Hydor thermostat designed for use with this cable. The wall plug is attached to the thermostat and the heating cable connects to that.

Yes you will need a thermostat. I used the one that was on the old unit and its working just fine.

No, this thermostat requires constant power - you will need a 24V "common" wire connected to the thermostat's "C" terminal. You would either need to run additional wires from your furnace to this thermostat, or there is an adapter you may be able to install into your current setup, but I'm not sure if you can make it work with only two wires. Either way you will need to modify your current configuration to include the common wire. See http://www.amazon.com/Venstar-Add-A-Wire-Wire-Adapter/dp/B0013LVDQA

Good question, this thermostat doesn't have a ground wire connection so I would wire the breaker wire ground to the heaters ground wire. Read your manuals first before wiring any product.

These units connect directly to the line voltage.. If your current thermostats only connect via romex type wire then these will work. If your current thermo has low voltage wiring (thin wires) then they will not work.

I never hooked mine up to the existing thermostat. There is one built in to the unit.

this unit requires 240 volts, which requires running a dedicated circuit from electrical panel and a line voltage thermostat to control temperature. I strongly recommend that this only be installed by a qualified electrician.

It depends on your existing thermostat. This unit requires 5 wires, with the 5th blue wire requiring 24V. If you have a modern 5 wire thermostat, it should work by hooking it up as you say. If you are currently hooked up to only 4 wires, I suggest getting an HVAC person to help out.

No the thermostat must have a B and an O terminal to energize the zone controller in the basement. Some companies make wirewless thermostatats that also interconnect to a zone damper panel
