Mitshubushi Mr Slim.
A Mr. Slim inverter system will def work in cold weather I believe down to the single digits if using a heat pump model.
Your other unit should work in 50 degree's it has a low ambient kit installed maybe a improper charge messing with stuff.
@MrBelvedere closest I've seen to a unit with humidifier built in is a very pricey but awesome liebert systems!
Hi there,
Interesting thread, I am also an hvac pro and been growing for over 20 years. Has any one considered the diakin units, I really like Mitsubishi and when it comes to vrf systems they are the only ones I would install, but when it comes to these smaller systems I think some of you people should check out the diakins. I also believe you can get diakins at johnstone supply which you'll have much better luck than buying from gensco.
Will this unit operate year round?
I live in the south where the winters are mild and have an Ideal Air unit that wont operate once temps get into the 50's. I installed a low ambient fan motor controller from ICM. It reduced the efficiency of the unit substantially and the it still shuts down once the temps get into the low 50's upper 40's. It gives the code E4 which I've been told by Ideal Air refers to the ambient temp outdoors being to cold.
I've tried a number of things recommended by the good people at Ideal Air. Everything from covering about 75% of the intake with cardboard to building a housing over it to try to retain some heat. The cardboard trick worked for a few days. Nothing worked more than about a half an hour.
I HATE THIS UNIT! My live is miserable continually battling this every day.
Why in the hell do they market this to indoor growers?
I have an older Frost Box that runs along side this one in an 8K room, both 24000 BTU units. The Frost Box is an inverter model and runs no matter the temps, even well below freezing without problems.
I'm debating on:
1: going the distance and replacing both units with a 4 ton Excel Air XL system or
2: replacing the Ideal Air unit with a 24000 BTU inverter type such as Mitsubishi. I have no problem getting a kit and doing the installation myself.
My concern with Excel Air is that it comes with a low ambient fan motor unit factory installed.
How effective are these in cold temps, i.e. low 50's down to freezing?
Will I have similar problems to what I'm experiencing now?
Would the inverter be the better purchase?
I know you like the Mr. Slim. Your recommendation would be greatly appreciated. I need to solve this problem for good.
Thanks.
Anybody using this thermostat? @O.O looks awesome.

I'm up in the Portland Or area and have been installing mini splits since they came out and I do agree that Mitsubishi is an awesome product. That being said diakin is just another choice and they are both equal in efficiency, operation, quiet, ect.. So just curious what type of problems you saw, sounds like you didn't install them. You know as we'll as I do a system is only as good as the person that installed it. Anyhow great job on this thread and just thought I would throw an option out there for them.
Only seen problems with Ideal Air. Mitsubishi is much better. IMO Excel is way overpriced.
