Features
Enhanced Modern Design
How do you improve upon an air handler that’s already silent? You make the appearance of it silent as well, with a premium encasing and elegant textures. A matte-frost finish ensures less fingerprints and time spent wiping. The curved edges give the system a softer look, and the LED display has been modified to show the set temperature in a more subdued fashion.


Cools like A Crisp Shower
Diamante Ultra drapes the room with a satisying breeze from above, without the mist. Cool air sinks from high to low, so we designed the system to let the conditioned air be “thrown” toward the ceiling, so that is can naturally reach as far as possible horizontally in the room, while also ensuring that the refreshing breeze is felt by all occupants of the room, no matter if they are sitting, standing, or lying down.
Heats like a Nuzzling Blanket
Diamante Ultra also wraps the room in cozy warmth, from floor to ceiling. Just as how cold air sinks, hot air rises - The system can use this quality to its advantage by directing the louver at a sharp downward angle, so that the air throw sweeps across the floor as far out as possible, and swells upward to saturate the room with a comforting blanket of warmth, to all four corners of the room.


Wi-Fi Controlled via Free App
Unlock the full potential of your new Pioneer system by activating the USB module included with your purchase. In 2 minutes you’ll be up and running, and ready to set custom schedules or fully control one or many units from the same app, easily and reliably, from across the world. Now you can pre-condition your home before you arrive, turn off the unit remotely or check that your pets are relaxing in comfort. You can also integrate your new mini split with a Smart Assistant, such as Alexa, Google Assistant, and Apple Siri.
Super Simplified Installation
Enjoy improved accessibility to the Diamante Ultra's crucial components. The bottom side of the air handler unit includes a hidden cover that is easily removable, exposing some handy elements that cut out a lot of the guesswork. Use the viewing window for making both the piping and electrical connections, and gain access to a single-press button to unlatch the unit for an easy removal.


Energy-Star for Efficiency
With its built-in DC inverter technology, the Diamante Ultra series brings big benefits for those looking to cut down on their electric bill. The outdoor unit compressor is soft-start and variable speed between 30% and 110% in both heating and cooling, and the indoor fan draws only a few watts when running. Take advantage of technology that is so power efficient, it is the go-to heating and cooling system for use on solar-powered setups. Silence and efficiency never looked so good together. Switch from your outdated system to the Diamante Ultra series and start saving today!

QUESTIONS & ANSWERS
Ask a Question-
In the installation instructions I see nothing for introducing (charging) Freon, though step 13 has me remove the “charge” hose in the “evacuating” section. Must your Diamanté series be charged “professionally”?
The outdoor section of the system already comes factory precharged with sufficient refrigerant to support up to 25 feet of utilized lineset. If you need to add additional refrigerant due to longer length lineset used, refer to Page 34 for proper parameters.

Great value and great service
I’m a DIYer and this was my first mini split install. It took longer than I expected to install but that is expected when doing something for the first time. I contacted Customer Service twice. Once by email and once by phone and received quick response to both. Phone call was to get setup instructions for Wi-Fi/Alexa integration not provided with unit. Wi-Fi setup was simple following the one page of instructions. Instructions don’t detail steps for taking measurements requested at registrations. A video of them would be helpful. Unit packing was top notch. Unit works well and super quiet. Very pleased with decision to go with Pioneer at this point.
Perfect unit for the cabana
I have a poolside cabana bedroom with a full bath that utilized the main house AC but didn't always stay cool. The best option was a mini split and Pioneer was recommended by many companies. They installed the unit and the cabana is as cool as you want. I was impressed with the quiteness of both the indoor and outdoor unit.
Phenomenal product and service
I cannot recommend this product more. This Pioneer Diamante Ultra mini split cools my entire unit just right. The unit has so many features and all work perfectly. I also had an installation done and the service was bar none. Great guys and a great product. A must buy!
Great value - works well after some trial and error with fan and temp settings
I'm a pretty advanced DIY'er and used a few different Youtube videos to help with the install. The only thing we hired someone for was to install the electrical line from the panel to the outdoor unit. I installed this unit in our home office, which is a former porch that was converted to a year-round room. Insulation is ok (not great) and it has a lot of windows, thus it was always a harder to heat space with baseboard. We decided to add the mini-split for heat and a/c and after about 3 months, we are very happy with it. We live in NH, where we see single digit winter days, and this unit has performed well. The main issue we had to resolve was that the unit draws air in from the top, so the warmer air, which naturally rises, would "trick" the system into thinking the room was warmer than it was. The solution is to set the desired temp to about 7 degrees warmer than what we want (meaning if we want the room at 70, we set the unit at 77). Part of this may be due to the ceiling slant in our room, but once we figured this out, we were good. The only other issue we recently solved was that "auto" fan was not really doing a good job of warming the room quickly and keeping it there. I changed to programming (via the app which could use some interface improvements) so the fan runs on high and this was a game changer. On auto, the room would take a few hours to come up 10 degrees, but by simply changing the fan speed to high, the room heats up within about 30 minutes. I am using the Airlink app which is not all that user friendly, and does require some patience. Mainly, the scenes that you create don't like to work if you edit them - it's best to delete them and start over if you need to adjust part of the scene. Overall, it works, and is nice to use/check the temp when away. After rebates from the feds and electric company, our overall investement was minimal, especially when compared to some quotes we received from HVAC companies. If you have basic DIY skills, I would highly recommend tackling this project yourself. Thanks for a good product, Pioneer!
Pioneer Diiamonte Ultra Mini-Split is excellent!
I just finished installing the unit in my new shop. I mounted the outside unit on a wall bracket, hung the indoor unit, and connected the power and communication cable. I hired an HVAC pro to cut and re-flair the linesets, check for leaks with Nitrogen, and vacuum out the system. This fee was less than what I would have spent buying the special HVAC tools to perform these tasks myself. The unit is going to heat and cool my space perfectly!
