Thermostat Replacement | 2 Wire | Heat Only

[@13BulliTs]

Thank you, it helped me a lot! It is so strange that you can hardly find a 3 amp 2 wire manual. I used this to connect my Avatto 3 amp wireless/zigbee Thermostat.

Thanks very much for the tutorial. I've watched your install, but cant seem to get mine to work. Connected to COM AND NO but still goes on non stop.

Can you use multiple wires thermostat with this 2 wires set up?

The old one needed batteries. Does the new one need batteries?

[@beargillium2369]

batteries are clearly shown on the new unit

So I wouldn’t be able to use this if I have an air conditioner?

Typically 2-wire thermostats are heat only. If you have air conditioning and heat, I would recommend a smart thermostat, as they will eventually save you money on your energy bill. However, in order to install and make use of a smart thermostat you will need to run a new thermostat wire (typically at least 4-wire with a 'C-wire') in place of the 2-wires, which can be relatively easy or difficult depending on your house and how far the wire run is and what it goes through. This video does not explain this process.
