Watch an easy solution to install a wifi thermostat without a c (common) wire. Either you dont have enough wires at thermostat or your furnace has no C wire connection.

Thank you for this video. I struggled to power my ecobee until I came across your video which showed me how to provide power to the thermostat. I have a two wire (Red and White) thermostat connected to baseboard heating (zone valve.) Luckily, I have access to a 24v transformer near the boiler and a spare wire coming to thermostat. Here is how I wired my ecobee: 1. Connect spare wire to 24v transformer labeled “Load” 2. On the thermostat end, connect spare “Load” coming from 24v transformer to ecobee ‘Rc” 3. Connect “Red” wire to ecobee “Rh” 4. Connect “White” wire with a jumper wire to ecobee “C” and “W1”. Please note; if you follow “White” wire back to the boiler you’ll notice it is connected to 24v transformer labeled “C” which provides power to zoning valve by completing the circuit when connected together with “Red” wire. Here is my diagram: drive.google.com/file/d/1Yx79pAtcSoadQqdU5ahQ6bVnKpcVWkKA/view?usp=drivesdk drive.google.com/file/d/1EG9Mvh_5hMfv6a7IDKoE2CIxKBvIyc1V/view?usp=drivesdk Hope this schematic diagram helps anyone with similar problems.

Amazing video... thank you. I have a boiler with no C wire running to thermostat. Bought the Nest and did not realize the issue until I got home.. Initially I had set it up where the Nest was power stealing from my boiler, but issues started to arise when it got really cold, and the Nest started to power out (all functions would auto turn off to compensate for the fact that the boiler needed the to run more often). Anyway took your reco and took it a step further and bought a 24V transformer that I installed inside the wall from the nearest power outlet - brushed up on my dry walling skills. Works beautifully now.. Cheers!

so many of the thermostats that just have two wires going to them have either a two pair wire like the old phone jacks which has four wires or even "3 pair" or "5 pair" or "7 wire" or any number of different low voltage wires to them from the furnace controllers I see how you have the two wires from the new Transformer but if all you need is a C wire and you have extra wires going to the thermostat from the area around the furnace which are not attached to anything wouldn't you be able to take one wire and run it to a terminal on the transformer in the furnace room to give you power to that C wire terminal on the thermostat or do you absolutely need to have the wire going to the jumped Rc terminal as well and additionally could you run both of them from the Transformer by the furnace???
