Great controller and fan

I am a functional mushroom grower. After trying many of the cheaper brand controllers and cooling/heating monitoring devices etc. I decided to buy the AC Infinity Controller 69 Pro and some UIS control plugs to connect my non-ACI humidifier and two external air conditioning units.

It was the most rewarding purchase I have ever made! However, despite searching high and low, I could not find out two pieces of information.

1. Will the controller work with non-AC Infinity products?

The answer is YES, but there are some limitations.

Your intended appliance (aircon in my case) must be one that when power is cut by the controller and then resupplied, your unit will automatically turn back on and maintain its settings. This is very important to be 100% sure of before buying either product.

So if you buy a Controller 69 Pro and the UIS Control Plugs, the USB-C connection from the Control Plug will power the Controller 69 Pro, as long as it is connected to a power supply (plugged into the wall).

In Australia you will need two US adapters for each UIS Controller Plug to make it work. (Note to ACI: please make AU plugs ASAP!)

2. Can the Controller 69 Pro be powered by a power pack connected via USB-C?

As I did not have time to experiment (I had blocks fruiting and just needed the tent functioning properly during a heatwave) I have no definitive answer.

What I have read is you can, but you lose one of your ports and really given you will be running control points, why give up that slot? In my case purchasing an air exchange fan was inevitable and the ACI unit I got is FANtastic!!!

After two weeks of operation I can honestly say this is the best controller I have ever used and I would never go back to the something-bird or the Otherthing-sun products (which I ran along side for a week and proved their inaccuracy was too much to gamble with fir gourmet mushroom cultivation). While I have kept them as emergency backup units, I would never trust anything but ACI to run my environment again.

As far as QBL are concerned 10/10 from me.

Excellent customer service, very fast delivery and when you need to sort out any kind of issue, they step up fast, friendly and effectively.

Soren and his team are truly the exemplars of the industry and I cannot thank them enough!

Server Cabinet temp control

Simply an amazing piece of kit. I tuned it for my needs to keep my server cabinet cool and its working brilliantly. The cabinet is in my main office so having it cool and quiet was very important to me and this thing knocks it out of the park.

Setting a temperature target is good but being able to set buffer and min/max speeds is amazing. On top of that I have it connected to Home Assistant (via HACS) and it work very well, can control the controller as well as individual output controls.

Super impressed & highly recommended.

Great Unit

The 69 Pro controller is a game changer. It also controls my old Mars TS1000 lights, which is amazing. The fan is quiet and powerful, as you would expect from AC Infinity. Lovely personal service too!

Shun the non believers

Well, really have no one to shun but myself. For so long I put off spending the extra bit of money for ac infinity gear when I have experienced multiple brands but ac infinity is definitely a league on its own. Quickbloom lights was super fast with their shipping can’t fault their service, future discount codes would be nice addition

How good is AC Infinity and qbl!!!!

Got a 3x3tent with hlg 600rspec.

The t4 is superb, moves air great. The controller is amazing and i can view it anywhere i take my phone. Can adjust on the fly. I have there humifier as well, the smaller one, T3. Comes with a bendy hose, which I can target my humidity. With all of this put together, i basically lock in my vpd which the controller measures. Humid, heat, vpd, all this control. Think of the beautiful flowers that will be...

Ive ordered the ion uva bars and the S6 fan. Ill let ya know how they go down the track... ordered saturday and they are in a truck on the road already... the first order i made took 2 days from landing in australia.

Qbl has emailed me many times, which i think is great customer service, even emailing them on saturday night and getting a reply pretty much within the next few hours. Love it!!!

The pos don’t work

Extremely disappointed and pissing off it won’t heat or regulate humidity??

Hi Jarrah,

Thank you for the feedback.
The fan, and any fan for that matter will exchange air in your setup, and for that it will be able to cool your room and regular humidity. It can not add or reduce with say a heater or cooler in the fan, but the movement of air will greatly help. We are not aware of any fan for this kind of setup that will have a heater or a cooler build in - but with the controller and probe you will always know the temp and humidity and it will greatly assist you in keeping this under control.
