Questions & Answers

In my paranoid case and to be absolutely clear, this goes inline with a 240v baseboard and allows for smart HVAC type temperature control Would I be able to use Stat/Nest/EcoBee, etc.?

Transforms 240 volt circuits down to 24 volts so that low voltage (24volt components) can be controlled while line voltage (240volt) loads are handled. It is the 240-volt baseboard heat source(s). This compartment is designed to fit heater wiring.

Is it possible to use one relay to control two baseboard heaters simultaneously?

As for my heater, I have 4 1000 watt baseboards and 1 1250 watt forced air wall heater running. All of them need to be run after the relay in parallel. Your total amps need not exceed 22 as long as your total amps do not exceed 22.

Installing this is an option, but what are the options? While I have read the installation manual, I would like to hear from one or two people who have actually installed ?

The system I had already had was a baseboard heating system with a Honeywell thermostat and an older relay module, which works exactly the same as the Aube did. It had stuck, and so I replaced it with the Aube, and I replaced the Honeywell with a Nest. Physically, the little Aube box goes on the side of an electrical junction box, fitting into one of the knockout slots. The low voltage would not comply with electrical code. You can use the Aube voltage regulation circuitry or your low-voltage The wiring for your thermostat should be in the SAME junction box as the wiring for your 240v heating. Therefore, the tube sticks into a knockout in the junction box and is fastened with a nut, and this is how the Aube's three high-powered modules are formed. A junction box is a safe place to enter the voltage wires. From an electrical perspective, it's also pretty easy. There are two wires that provide 240v power from your panel, a black hot wire and a white neutral wire. connected to the same junction box where you have attached On your baseboard heater you'll find a black and a white wire. To make the heater operate, you would need only wire the white wire from the panel to the white wire from the heater. In this case, the neutral wire remains connected all the time and does not need to be In the situation in which the black wire from the panel is also connected to the black wire of the heater, your heat would still be running, but it would be on 24/7/365, and you might burn your house down, or at least be sweltering. This is obviously something you would not want. To turn the heat on and off, you need a switch. An Aube is your switch, and it lies between the hot wires leading to your panel and the hot wires connecting your heater. The black wire of the Aube connects to the black power wire from the panel, and the red wire runs from the Aube to your Whenever the Red wire is turned on or off, the aube turns on or off your heater. That leaves the blue wire. The blue wire is only used to power the small transformer inside the AUB that runs the relay and As you can see, the blue wire is connected to the white neutral power wire provided by It's also possible to twist the blue wire of the Aube with those white wires, and you'll be good to go. 'br> *br>You might notice that the Aube's red and black wires are 12 gauge, which means your heater is getting the full power load of the converter. The wire connecting the blue wire and the Aube's internal transformer is only 16 gauge, since it is only there to power the Aube. Please use good quality heavy-duty construction in all cases We suggest you use wire nuts or other wire connectors that are rated for 240V 12 gauge wire, and did I mention before it's important to turn off the circuit breaker that runs your heat first? that's the case, I'd suggest you hire a professional to hook this up. You can use a simple two-element model An example of a mechanical thermostat is a Honeywell mercury-filled round thermostat Having the bulb thermostat connect across the Aube's R and W screws is a good feature. You probably have a thermostat wire in place already A thin-shell Cables with the appearance of telephone wires In actuality, it will be red and white. *br> *br>The R screw terminal is a low-tension terminal. This electronic device is powered by 24 V internal power supplied by the Aube's In the Aube, W corresponds to the wire that turns on and off the relay (and your heat). line is often discussed when installing smart thermostats like Nest. Having the third "common" wire allows your thermostat to draw 24 volts of power throughout the day, without affecting your heat settings via the white wire. In my installation, there was already an unused third wire. However, it has been colored green, not blue, which is the more common color these days, and is just as effective. At one end, the three thermostat wires, red, white, and green, were screwed into the R, W, and C screws of the Aube, then to the Rh, W, and C screws of the Nest base plate. There you go!

How does it work with two of these having the same My contact with Aube tech support indicated that I could do it, but they must still ?

This is a 2-pole relay, so think of it as a Apply a lower voltage to the coil (24 v from T - ), and that thus activates the two-pole Any downstreat is turned on. The following heaters are available 1 heater, 2 heaters and so on.

The installation of the electric heat control is extremely simple
5/5

In order to add a thermostat to a basement room with electric heat, an additional relay was needed. The item required to resolve this issue was just right for this situation. It was simply spliced into the 240v (US) cable at a point where the current was already flowing. At first, I had hooked this up backwards so that the heater worked but the thermostat failed to operate. Now that I have switched the wires around it works flawlessly. The 240 volt wire from the panel is The Black Panther It begins with The Aube* is black, and the White is white It begins with The heater and the fan are white The Blue on Aube (Three in One)* by John Cage This is Abe The black color – It begins with The panel shows Black on 240v and Red on 400v with no problem It begins with The top of the heater is black, and the bottom is blue It begins with There is white on the heater and the fan (Three in One) is White on 240v, and it is available from a panel outlet - The heater must be plugged into 240v The black color – It begins with The red on the white is called Aube

I upgraded my work shop and it has been great
5/5

Everything seems to be going well so far. AN easy to install 5000 watt Comfort Zone 240 volt garage heater was installed by me just a few days ago. Although I had a little trouble figuring out which wires were going L1 and L2, I was able to figure it out in the end. In the reverse order, I had them. Immediately after switching them, the nest thermostat e that I hooked it up to worked like a charm. The insulated shop employs it along with an overhead garage door for 400 square feet of space. After the upcoming Central NY winter, I will have an update to this review. The ceiling may need to be insulated. I am updating to version 5 of the update There's a big problem with the heater fan in 2020 it's really noisy and I was very happy with the results of the nest and transformer. Insulating will be a priority for me from now on. In my 2500 sqft house, to force my shop to be 45 degrees F, it cost half as much as to force it to be 40 degrees F.

I don't see the point of this device
3/5

It makes no sense to use this device. According to the product information, it controls a 240-volt heater, but with only three wires, there is no way for it to control two 120-volt outlets. In order to do that, you need a minimum of four wires (corresponding with the line and load ends on both legs). It is clear from the above that this is not a DPDT or Even though I am pretty knowledgeable about electrical wiring, for the life of me, I couldn't figure out how to use this device. To solve the problem, a 24 volt transformer and DPST contractor had to be purchased Furthermore, the cost of doing so was half of what it would be otherwise. Although this device is overpriced, it still seems to offer great value.

The weather is finally warming up! The living room of my home was already installed with two baseboard heaters that were controlled by a single thermostat when I bought it 12 years ago
5/5

We've never experienced a warm house even when it got down to below zero and the heaters couldn't keep up. An 8000-watt generator. Nonetheless, I have always blown a thermostat every year, and have a few times come close to a fire scare. This and an Aube Technologies 300612 RC840 were finally purchased. The circuits were installed and run separately and each of the baseboards now have a dedicated circuit of 20 amps. *Now, FINALLY, This problem was caused by too much juice, which caused the thermostat to perceive the house as much warmer than it was, and so it turned off before it should have. It has now been resolved and there is no longer any threat of a fire!.

Using modern (and wifi enabled) thermostats with 240v heaters is the best
5/5

It was used to supervise existing 240 volt space heater circuits. Our Honeywell WiFi thermostat allows me to monitor the temperature at our cottage from home, as well as turn on the heat before we leave, so it is warm when we arrive. We can even ask Alexa what the room temperature is, or adjust it with its voice. In addition, Honeywell's monitoring app sends me emails if the wifi connection is lost (usually due to power outages) or if the temperature is higher or lower than I set it to be. Every setup and location I've done has been powered by Honeywell. In areas without gas heat options, the Aube gives me control over areas I was unable to control with gas heat. Another one of these devices is used for one of those 4800w space heaters in the garage that is powered by a 220v plug. Similar setups are found in other garages, but they are heated with gas. I recommend you to go to.

I really like this product
5/5

Google Nest thermostat is compatible with this app. One of these was installed and so far it has worked fine. I had an existing two-gang box on the wall with a single plate on it that took some time to replace. The wiring of the unit did not fit into the box due to all the wires. Because of the writing on the box, I wasn't able to get a bigger one to replace the existing one. Another box top will need to be placed over it, and I just have to run the cables For the cover, I bought two flat plates which I covered with flat plate covers, and I ordered metal alloy 9"x 12" plates, which you can order if you wish. During the installation, I cut a hole into the wall and put in the Pictures are available on the site. My wish is that it will last a long time.

It's a great idea to install a smart thermostat for electric baseboard heaters
5/5

To install the Honeywell Lyric T5 Thermostat on 240V AC electric baseboard heat, I used this kit. In addition to my old manual thermostat, I still did not have a smart thermostat, and a very limited number of programmable thermostats claim to work with such In my search for a solution, I came across this part, and it worked great. This is the Aube RC840T that I have installed I ran 3 conductors to the new thermostat to the north, west, and south (C, R, and W), and had to modify the circuit 240 where the previous thermostat was (I had to install another junction box). In addition to the modifications to my wall, it only took about 30 minutes for the install. I am very happy with the new thermostat. I am glad I was able to find this device, because I can use it to control all of my home's systems from one location. I'm experiencing a problem with my fourth Lyric Thermostat (the others control the heating system, hot water baseboard system and A/C). If I had to replace all of them, it would have been quite costly. I highly recommend this to anyone who needs to install a smart thermostat on an electric baseboard heater.
