Cielo Breez Max upgrade for Mitsubishi mini splits
I’ve been using 3 Cielo Breez Eco units with our Mitsubishi splits. I purchased these to operate the splits remotely, as the cost of Mitsubishi’s OEM Kumo Cloud device was extremely expensive per split. I came across the Cielo Breez Max while searching for an alternative to the Kumo Cloud controller.The Cielo Breez Eco worked extremely well for the year and a half that I’d owned them. However, we had a problem with one of the splits making a lot of noise (two pitches coming from the unit when the unit was running), and the owner of the company that installed the system came to the house to evaluate the issue. I’d shown him the Cielo Breez Eco and the app, and he was thoroughly impressed and told me that he’d take the information about the Cielo products back to the shop and recommend it to his customers (a lot of his customers are elderly and on a fixed income, and he stated that they couldn’t afford the Kumo controller, in addition to the fact that they were technically challenged). He had one of his technicians come to the house to repair the unit, which turned out to be a controller board that wasn’t getting enough power to run the fan and the motor, which was causing the dual pitched noise. After replacing the control board, and when using the Cielo app to test out the repair, it was noticed that only one side (right) of the set of louvers were actually being controlled with the swing feature, which concerned him (and me!).After the technician left, I immediately contacted Cielo Tech Support regarding this problem. The tech support representative explained to me that on some mini split units, only one side would be controlled by the Cielo Breez Eco with the app (as some splits only have one set of louvers), and that to get those to work properly, it was advised that I purchase their Cielo Breez Max item, as it has additional features that the Cielo Breez Eco wasn’t designed with.Wanting to be able to have a better functioning split, I went ahead and ordered one Cielo Breez Max device through Amazon in order to install it and test it. The Cielo Breez Max arrived promptly and I installed it and ran it through the evaluation process. (NOTE: Following the instructions to pair the Mitsubishi remote with the Breez Max, it still did not control both sets of louvers. But, since I’d had the Breez Eco devices in the past, I knew that I could call Cielo’s tech support and they’d get me up and running.)Working with a Cielo tech support technician, they have access to my Breez Max device, and he went through a couple of remote control models and was able to get me up and running perfectly in no time! It’s great to be able to have both sets of louvers (when selecting the SWING feature) working! Plus, after working with him, he gave me a discount code through Cielo to purchase the 2 additional Cielo Breez Max units to pair with my additional 2 mini splits.After receiving the 2 new Cielo Breez Max units from Cielo, I installed them and again contacted Cielo’s tech support to have the technician get the proper model selected for the splits so that they all had the proper settings to control the swing feature on the splits. We’re up and running with all the splits working as they should.As a point of interest, which I did not know, when finishing up with the latest technician, I was a bit concerned about the fan speed not coming on immediately upon initiating the heat mode. He had me select the cool feature, and the fan speed came on immediately and responded when changing the fan speed and swing feature between the different levels. He then had me select the heat mode; it didn’t come on immediately. However, at this point, the technician explained that this was normal, as the outside unit takes a bit to heat up, and when it does reach the proper heating temperature, the fans will then actuate and start blowing as they are programmed to do, which they did. His description and explanation alleviated any anxiety on my part and reassured me that everything was working as it should.An important feature to anyone having multiple split units is ensuring that ALL units are in the same selected mode (heating, cooling, and dry modes – “a multi-zone mini-split system can only function in either cooling or heating mode at any given time, but not both simultaneously, as they have the same refrigerant flow. This limitation often leads to mode conflicts when one unit is set to heat while others are operating in cool mode or vice versa” so as not to damage the main unit). The Cielo Breez Max has a feature called “Multi-Zone Mini-Split Control” where you can create a setting to ensure all devices are switched to the same mode when turning on one unit to avoid damaging the system.I am thoroughly pleased with my purchase of the Cielo Breez Max | ENERGY STAR CERTIFIED Smart AC Controller | WiFi Thermostat for Mini-Split, Window, Portable ACs/Heat Pumps. It’s nice to have an item work the way it’s advertised to, and it has a user friendly interface, compared to looking at the OEM remote and trying to figure it out with all the different symbols, features, and having to slide the keyboard cover up and down to select and change to different modes and settings. And, primarily the feature to control your splits remotely through Wi-Fi connections when away from your property (which is why I initially purchased my Cielo products) is the main reason I purchased the product(s).I am totally satisfied with my purchase(s) of my Cielo products, namely the Cielo Breez Max. And Cielo’s technical support is top notch. The technicians that I’ve worked with are professional and very knowledgeable. And, I like the fact that they are very concerned with how their service to you was, as they follow up any contact with them to ensure your product is working properly and to see if you’re having any other problems!The Cielo Breez Max is a great product, and I most highly recommend this item, along with their other fine products!

Top Notch Customer Service.
Decided to have a Bosch Cold Climate Mini Split Heat Pump System installed last year because of the promise of the heat it would provide below 32°, unlike the Central Air Heat Pump we were using. Living in the Northeast as soon as the temperature outside hit 35° the old system could not produce any heat and basically became useless. Was skeptical the Bosch Cold Climate Mini Split System could or would pass the test, but we were throughly surprised by the performance and energy savings the system provided. We had heat with the Bosch heat pump / min splits with wind chills below 10°. My HVAC installer would call to check on how well the unit was running for me and if I was satisfied with the performance. On one occasion I mentioned I was extremely pleased with the system he installed and the placement of the mini splits and how that gave our two story home complete uniform heating coverage in the coldest weather. Then I said: “The only thing I missed was the control I had on my old system with the Sensi Thermostat I installed”. He was of course calling me while driving to his next project and he said I know there are third party thermostats for mini splits but could not remember the exact name.Enter GROK and a search for a smart thermostat that is compatible with a German made Bosch Mini Split. BAM! Cielo Breez Max hit my radar as the #1 choice for a smart thermostat. Went to their website and dug into its capabilities, their website had a reference page that told me my remotes for the mini splits were compatible with the Cielo Breez Max. So far so good. Hit click to buy and it linked me to Amazon. Read the glowing reviews on Amazon (which are true) and it was a no brainer. I have now taken charge of my heating and cooling from anywhere I am with my cell phone, with the additional cost savings I will have with such control. I’m in HVAC / Mini Split Heaven. Let it snow.Now after receiving my Breez I had questions about certain functions and picked up the phone calling customer service, several times. This is where the company shines, they leave no detail go and will not leave you hanging bewildered with their guidance. Impressive and honestly I have never had so an experience with any company. Bosch and frankly all companies can learn from the folks at CIELOWIGLE. Their customer service is top notch and will make me a repeat customer forever.

No funcionó con la configuracion qué tenia el termostato. Escribí al servicio técnico y me lo solucionaron de inmediato. La marca de mi AC ni la.conocian, me hicieron unas preguntas y lo arreglaron. La verdad no me lo esperaba. Y el servicio al cliente fue excepcional.

C’est un excellent appareil, qui fonctionne très bien avec l’application Cielo Home et la liaison avec Alexa. Super service à la clientèle (je n’ai jamais vu ça autant de rapidité et de compétences à la fois) pour vous aider à finaliser votre configuration personnelle en fonction de vos besoin spécifiques. Sinon, l’installation peut très bien se faire sans aide, les contrôleurs (télécommandes AC) étant détectés rapidement. Je recommande ce Breez Max sans hésiter!
