Product Overview

Designed and built in Germany with highest standards for safety and quality, Synergy 370 is the first residential garage door operator system that offers integrated LED lighting. Not only is LED lighting very energy efficient but with a life expectancy of over 30,000 hours you will never have to replace a burnt-out light bulb in your garage door operator again. LED extension kits are available to double the lighting capacity from 500 Lumens to 1100 Lumens. An integrated battery back-up system ensures that you can open and close your garage door in case of a power outage. As an additional benefit, the LED lights of the Synergy 370 will continue to work when the opener is running on battery power. A pre-tensioned, 2-piece belt rail system allows for an extremely easy assembly, while a 3/4 HPcs motor provides for an amazingly quiet and powerful operation. Synergy offers programmable door travel speeds up to 9.3 in. per second and can be set separately for the up and down travel cycles. An integrated LCD display guides you through the simple 3-step programming sequence while the Synergy 370 automatically calculates and maintains the force and sensitivity levels required to open and close your garage door. Considered the safest and most reliable garage door operator system available, Synergy 370 will provide you with many years of reliable and maintenance free performance.

Customer Questions & Answers

I have a 2003 vehicle and 2012 vehicle homelink equipped, will it work with the Synergy 370 or do I need to buy an adaptor?

The 2003 is a Mercedes Benz, the 2012 is a Mazda both factory installed homelink system in the auto-dimming mirror.
Asked by: Willpower
Yes, the Mercedes vehicle with Homelink installed will program to the Marantec Synergy 370. Your 2012 Mazda may or may not have Homelink in it. The manufacturing date is very close to when LearCar2U was still installed in them and then they starting switched to Homelink (2011-2012). Please confirm with your vehicle manufacturer that your Mazda vehicle has Homelink and not LearCar2U in it. As long as it is Homelink then it will program to the S370. When following the Homelink instructions, when it asks about a "Learn or Smart" button you will press the active button on the Marantec remote to program it to the vehicle. There is no "Learn or Smart" button on Marantec products, use the "active" button on the remote to program it to your car. You can visit for programming video's if needed.

Synergy came with our new house. Its great in every way but the light is dim, very dim. Is this the way it is or can it be brighter?

Asked by: Whalestail
You can add more LED's to these units to make more light. I havent done it personally but I know it can be done as I have had training on the Marantec systems. If you go to their website at , I am sure you will find them or you can check this out as well

Customer Reviews

Synergy 370 3/4 HP DC Motor 7' Belt Drive Garage Door Opener with LED Lighting is rated 4.8 out of 5 by 12.
Rated 4 out of 5 by from Excellent product, with one exception APPEARANCE: Nice white motor box with side panels of covered LED light. Looks good overall, and they have some nice hardware setup that allows you to hide the wires for view for the most part. They instructions don't call this out, but you can feed the motion detector and opener wires through the body of the motor so they aren't hanging, and you don't have to cut the wires down to size, just wrap the excess into the body. ELECTRONICS: Simple controls, {P, +, -) with a clear display. Setup is three straight forward steps. Had some issues with the setup, and it gave a code that was easy to look up in the manual and diagnose. NOISE LEVEL: Very quiet, noticeable improvement over my old opener. Unit accelerated and decelerates a couple seconds before it reaches the top or bottom and comes gently to a rest, not crashing to a halt. ACCESSORIES: Remote openers are small and easy to set up. Motion detectors have nice little lights on the top to let you know they are functioning, and blink when they are obstructed. Keypad and inside wall units are solid and look good. INSTALLATION: Not an easy one person job. The hardest part for me was trying to keep the unit elevated so I could attach it to the joists in my ceiling. Make sure you tie the bar to the joist so it can't fall to the floor unless you have someone to hold it. It is doable though, you have to be patient. Make sure your connector is in the right spot (more below.) INSTRUCTIONS: Overall good, but I had a very difficult issue with a seeming omission that caused me a lot of grief. The drive belt connector was on the wrong side of the bar (up against the sprocket.) Since the connector cannot get past the sprocket, this meant the door could not open. Unfortunately this was not covered in the instructions. It also wasn't apparent until the unit was installed and I operational. I added a video of the issue to YouTube (part 3), check before you install. CUSTOMER SERVICE: I emailed Marantec customer service, asking for clarification if the above issue was with the instructions, or perhaps I missed something. Their answer was polite, but not at all useful, and offered no additional info. They did say they would forward the issue to engineering.

Rated 5 out of 5 by from Awesome opener! I installed this about a year ago. The old original one that came with house was pretty beat up and seemed to really be working hard to open door. Pulled old and installed this Synergy opener. What a difference! Opens door, no problem. And very quite. In the house, you can't even hear garage door open! Remotes are slick. Exterior keypad is a nice touch. Highly recommend.

Rated 5 out of 5 by from Quiet garage door opener with power backup and led light I don't have access to the garage from inside the house thus I need a garage door opener with power backup in case of a power outage. This is what I need. It's very easy to install. It operates very quietly, and comes with LED lighting. Even the LED light comes with battery backup. Perfect.

Rated 5 out of 5 by from Excellent Opener, Very Quiet I have installed several garage door openers over the past few years and this one is by far the best. I really like the quiet belt drive and modern look. Installation was not super easy, but wasn't too bad, however, I have installed several openers and knew what to expect.......for the most part. The directions were pretty good, not great, but anyone with some DIY experience and some patience should be able to follow them. For the most part, it can be done by an individual, however, a team of 2 would make life much easier. The operation is very quiet, especially compared to a chain model like most people have today. Not that the noise ever really bothered me, but this door will not awaken anyone in the house if it ever gets used late at night. The description of the model on the website seems to stress that it's the first model with LCD lighting. That's great because the lights in my old unit went out all of the time. This model's lights should last longer than me. Also, it comes with a life time warranty. Hopefully I will never have to take advantage of it, but I think that speaks to the quality of the parts Marantec included. I would definitely recommend this to a friend.

Rated 5 out of 5 by from Super quiet operation Extremely satisfied with how quiet our garage door operates now. We had a 30 year old opener you could hear from across the house, and now we can't even hear the garage door operating from the next room. This was a time consuming project, it took my husband about 6 hours to install (including running the wires for the opener and lasers). The instructions might be a little difficult to compare to your system if you have a low clearance door because where they want you to install the end of the track is right where your springs probably are. We just went right above our springs and it works beautifully. FYI this would be a very difficult project for a beginner, I would recommend you get help from someone with at least basic construction skills. Love the included backup battery. We live in the country and power outages are somewhat common and I hate having to manually open my door to get my car out for work. This will be a huge bonus for me. The LED lights are bright, and it's nice to be able to turn the light on manually from the keypad. Comes with two remotes for your cars and a wireless keypad (battery operated). The laser safety mechanism was not a pain at all to install and works quite well to the amusement of our dogs. The door moves fairly slowly, but definitely slows down a bunch the last 6 inches when closing for a very soft and quiet close. Seems very well made (it's from Germany) and am hoping it lasts us years.

Rated 5 out of 5 by from Quality is worth paying for. I did have friend who has experience installing garage door openers do the install. He said different than other manufacturers, but the quality of the equipment is superb. It looks great in our garage and operates very quietly! Comparing it to the older opener on the other door, the Synergy is much quieter and smoother, and only a little slower in opening and closing. Worth the trade off. Very well made product.

Rated 4 out of 5 by from The good, The Bad, and the Ugly There was a marentech opener on my garage when I bought my house. After about 7 years my unit died due to a power surge, despite the lifetime warranty, it was not covered. I replaced the power head for about the same cost of a direct screw drive competitor installed. So I would offer that electronics and features come with a potential cost. The unit is quieter than any other garage door opener I have ever owned. Yesterday the power head died. I will be calling the local authorized dealer to see what they can do. Will they tell me that the warranty will cover it, or will they find another reason not to back the warranty? Who knows? The good, Quiet and seeming huge warranty..(The warranty did not work so good the first time) No lubrication needed .. Belt is Kevlar .. look at the warranty and pray for me. and they finally re engineered the remotes, old ones would break apart and required tape to keep them in one piece. The Bad .. Two broken down units in 13 years? Durability is questionable. The Ugly.. Really Really expensive (note for that cost they should be backing the warranty)

Rated 5 out of 5 by from Excellent door opener Excellent garage door opener. Only con I have is for the owner's installation manual. I would give the manual only a 3 out of a 5! Over the years I have installed around 8 to 10 garage door openers. This is the first time I had to contact the manufacturer for instructions in order to complete the installation.
