Is this a 2 wire hook up?

Yes, but it is not a contact closure thermostate. It is a millivolt, so it draws power from the line.

yes 2. one wire in back for normal plug in. also one port in front in case your other devise has wire. works out great.

Based on what I know after installing to my whole house phone wiring, I would have to say "NO". There would have to be two phone out connections and each would have to be dedicated in order for a two line system to work.

No, look at the picture. It has 2 inputs and 1 output. It is to be used to switch 2 cables going into 1 television.

They come with 2 and4 wires. Unless it specifically states 4 wire I would assume the more common 2 wire.

Yes it must be hardwired, but only two wires must be connected. If I did it anyone can. Good luck

Yes, it is a two wire or more. I used it with two wires and it works fine. However I needed to purchase a coverplate to cover the whole. I bought the Honeywell 50002883-001 which allows for a couple of cover options. I have a vertical box behind the wall and the thermostat needed a horisontal box.

You need to take a look at your switching valve.count the ports and is it one wire or a multi wire plug.this unit you are asking about is a single unit..hope this helps you.

I believe it is just 2-wire. We use it to control our pellet stove. Works great.

I do not know if it would work on two wires. You can go to google and or the manufacturer for the answer.

It only has two wires. It reverses polarity to go the other direction. You would have to search for information for converting to a 2 wire harness.

Direct wire for sure. I don't recall there also being a plug. Could there be 2 models?

This plug has 2 female ports for rca. So you probably need this a wire with two male connector instead.

Not sure about your heating system, but mine has two wires only. I connected them to R and W with no issues.

Yes, but connecting two outputs doesn't do you any good... Maybe try connecting it to the line in on a computer.
