HoneywellTransformer

Paid a little extra for the Honeywell name, hoping that it would pay off in the long run. Seems to run fine. Been going for about 6 months with no problem now. I would definitely buy again.

Compatible 100% con Ring Doorbell y Timbre de Casa

I am sure you have read all over that Ring Pro needs a decent transformer. The one in the house was just not powering enough. Its been only 2 days that the new transformer is in, but I am able to "answer", "watch live" the Ring Pro with significant less lag than before. The voltage on Pro after replacement is consistent between 3920 ~ 3975 mV (Pro recommended range). I will come back and update this review after 2-3 weeks to let you know how this has been working.This transformer can be foot mounted - for those folks looking at the packaging and trying to decipher how to mount - just screw the transformer feet on the wall where there is solid backing!

Highly recommended. For anyone who buys an ecobee or smart thermostat and has only two wires to their furnace or boiler and needs to run new wire, this is a godsend. I tried to hire someone to install it but ran into timing issues so I did it myself. It was fairly easy. This transformer is a step down transformer to 24v, the perfect amount for a thermostat. It comes with a large electrical box mounting bracket that enables you to easily mount it onto an existing or new box. I wired mine to an existing junction box and then put in a small junction box to join up the two wires (red/white) from my boiler to the two new wires (yellow/blue) coming from this transformer. My ecobee4 is now powered by this transformer and has been working fine for a week. This transformer can be mounted in three different ways and comes with complete and easy-to-understand instructions.

My furnace transformer blew. It's a 20VA, 24V/120V transformer. The part is not available from Homedepot, Canadian Tire, Rona or Home Hardware. I found this 40 VA Honeywell which can handle double the power and decided to give a try. After I installed, it worked great. Because it is more powerful, I should have no problem installing a digital thermostat that takes addition power from the transformer.
