Questions & Answers

The included jumper wires will still be required for the Eufy doorbell once you put this transformer in place? You were able to use your existing chime, right?

They connect the transformer directly to the doorbell button through the jumper wires, bypassing the doorbell chime. As of right now, there is no way to use your chime with the Eufy doorbell, so you must either disregard the chime or use the wireless one included with the device.

Grounding the transformer what do you need to know?

In order to connect to the AC power, the transformer needs to be threaded into a knockout hole in the electrical box. All modern (metal) electrical boxes have a ground cable that screws onto the box to ground the incoming power cable. When it comes to plastic (yuck! Unless you need to ground the transformer itself, there shouldn't need to be a grounding wire.

The doorbell wires for the ring pro 2 connect to terminal r and terminal c on the 4011mt transformer. Which wires connect to each terminal?

The transformer has only two contact points on the output side. It would be wise to examine the wiring of your current transformer and move them as they are configured. For a more 'educated' answer, you should call Ring tech support. In any case, I would do the same.

Will it toast home classic doorbell if it has a 16v supply?

After looking at the instructions which say it can use 9-volt batteries, I bought the classic Compared to the 16v, I replaced this one with 24v. I can use it without a problem.

This is the first time Ring Pro has worked correctly
5/5

The Ring Pro doorbell has been in my home for about three years, but I never knew it was not working as it should. Ring Pro doorbell was installed as directed, and I installed an external Power Kit on my existing doorbell. It also showed that I had a 16V transformer for the external doorbell. A few weeks ago, I noticed that my doorbell would sometimes hang and occasionally go offline. Ring is the company I went to online. You can visit www. ringpro. com and read reviews there about the need for a 24V transformer in order to power the Ring Pro and your internal doorbell (if you have one). Due to the fact that the 16V transformer was old, and probably not providing the power needed, I decided to replace it with this 24V transformer. fairly easy to change the chip and upon testing discovered that the internal now plays the Ring sound as well as the original ding-dong sound The sound of a dong. Simply put most 16V transformers (let alone older ones) are not capable of providing enough power both to power the Ring Pro and As I said, I hope this helps because the frustration of the Ring Pro going offline and preventing you to answer the door from your phone causes anxiety. You do not know why the Ring app cannot connect to your Wi-Fi when attempting to open it. The error message "Cannot connect to your WiFi" means that either the device or the router is to blame. This transformer has not caused me to experience this error since I installed it.

I use it with Ring Pro doorbells and it works great
5/5

My Ring Pro was not able to get sufficient juice after I had read a few reviews. ***** I contacted Ring service, but they sent me a replacement kit that was not working A kit like this has already been used by me Due to not knowing what the error was, they could not find it It appears they thought it was my WIFI, which I have checked and it isn't. As I did some digging, I discovered it was the power that caused the issue. Since it also powers my regular doorbell chime that drains the juice every time someone rings the doorbell, I guess it drops juice every time the doorbell chimes. A solution has been found to the problem.
Oh yeah, that's it.

This is an essential part to a properly functioning smart doorbell
5/5

A couple of days ago I installed a Ring pro doorbell. Before attempting, I watched a few installation videos on YouTube and upgraded the transformer was the critical element.

Installation was straightforward. Find the breaker controlling the transformer, then attach the two wires connecting white to white, black to black, and ground to ground, then connect the two wires connecting the doorbell to the top screws. I first noticed the Ring was not getting enough voltage after setting everything up, but after a while I saw it showing normal voltage and it has been showing normal voltage Although I'm not certain what needed adjusting, everything works and this transformer has enough voltage to upgrade my thermostat as well if I so desire.

I find it to be very useful
5/5

I was able to set up my ecobee4 themorstat to With my old furnace, there were only two wires to the thermostat - I think they were W and Rd with a My thermostat wire was damaged. I have bought an additional one. Specifically, the old thermostat wire was connected to W and Rh, and the wires from the transformer were connected to C and Rh. You must turn off the power before installing the transformers since they have markings to tell which is the C cable. When installing, be sure of turning off the power. To make sure the power is turned off, I always check my voltmeter after I shut off the breaker. It is best to get a professional to help if you do not know how to do it.

It is compatible with the SimpliSafe doorbell camera
5/5

My SimpliSafe doorbell camera worked perfectly with this. "Ding-dong" is the sound of the old style mechanical doorbell I have The underpowered 12V transformer in my unit had prevented it from working, so I replaced it and I had no problems. As a result, I did not have to run a resistor or apply the SimpliSafe "fix" for my doorbell to work. The problem others are experiencing is the problem with the new electronic door bells that use a much lower voltage draw. You may be mistaking the low voltage draw the doorbell camera uses for a trigger, which perpetuates the nonstop ringing.

In my opinion, the fix would be to set up a resistor or small relay instead of a transformer at the bell "hot" wire. Consequently, it does not let current flow to the bell until the full 24v is activated just before someone presses the.

The heat is intense at 28vac, but it is UL listed and a very solid product
4/5

Initially bought this to run a video doorbell, but it puts out far too much voltage to run the particular model I have. The meter read 28 volts. Despite the manufacturer's recommendation of up to 24VAC, the doorbell units can only handle 2VAC. Transformers run hot, but I was not able to use this one due to the temperature. It is important that you contact the manufacturer of yours before installing. Apart from that, its a fine product that is UL listed and very sturdy.

I have a (wired) Eufy doorbell camera 2K which works nicely
5/5

The device was bought to interface with the Eufy doorbell cam, which requires 16-bit SD cards 240 volts. It is estimated the transformer in my house was built in 1970 and provides just 8 volts. The port of entry was in the basement, along the joint between the ceiling and the wall, near the breaker box. When buying a doorbell camera such as ring, Eufy, Nest Hello etc. make sure it can work with internet connection. To make sure your doorbell functions properly, you will need a transformer able to provide at least 16VAC. I had some issues with the packaging, it was just thrown into a cardboard box without any wrapping, but other than that, everything was fine.

Thermostat is compatible with Nest
5/5

Product of high quality. I used it to control my millivolt heating system by installing the device with a relay. Installed on the junction box, I connected the red and white wires from the transformer to the Rh port of the Nest, then ran the red wire from the Nest to the control side of the relay and then the white wire back to the other terminal. In my case, I have a red and white boiler wire connected to the opposite end of the relay and it controls the boiler wires whenever node 24 completes the Keeping the Nest charged and avoiding the possibility of the 24 volt and millivolt circuits coming into contact with each other is nice.
