What Does FP Stand for on a Mini Split? - Ask the Expert Episode 222

Today's question comes from Jeremi. "Hey Dan, what does FP stand for?" Wow, that really depends on the context. In this instance I believe he's talking about for a ductless mini split. So, like on a MrCool Mini Split remote you will see a button that says "FP" and what that stands for is Freeze Protection. Basically if you're going to be gone for a while and you just want to keep the place where the unit is from freezing, you want to keep the pipes warm, you put it in FP mode. This will allow for the temperature to drop, but it won't get so cold that you have to worry about pipes freezing. It should keep the area above 40 degrees. This is also good if you have your mini split in a vacation home or a place you don't visit that often, but you want to keep it protected. Have more questions? Be sure to leave them in the comments below!

Frequent Pooper... classic lol. I just bought a home in Mexico and it’s filled with mini splits. Like you mentioned I won’t be here a all the time so I do want the FP on so that’s good to know (thank you) but I have another question. I turn the unit on, set it to 24, outside is say 36, everything starts up like normal and I see the FP message but the system doesn’t seem to be pushing really cold air. Is it cooling to the right level when you see the FP message? I don’t know if all systems are the same this one is from a company called Prime. I’ve read all the manuals and they mention FP but don’t explain anything about it. Thanks False Pretenses Fake Pony Fantastic Palapa

Can you put the mini split in freeze protection from the app?

Hey Dan, thanks so much for the info! I just installed a minisplit for my sun room as a DIY project. Woke up this morning with FP on the unit display. "Failed Project" was my first thought. What a relief to find your video online. I watched several more for entertainment. You got any advice about a "Failing Prostate"?

Thanks so much. I really enjoyed your video. It was very helpful. Before watching your video and fully understanding what the freeze protection setting was I was concerned that I would have to leave our five mini split units set at 62° which is the lowest setting available. We have carrier units which say heat 8°C which is our FP setting. If this setting can prevent the pipes from freezing that would be fantastic and would save me from either having to overheat the house or shut the house down each time I leave. Again thank you so much.

I have a Premium Levella RGS7A6/BGEFU1 mini split. I had my temp set at 70° and I accidently hit the FP button on my remote. My temp started dropping in den and I could not figure out how to disable the FP. I finally turned the unit off for approx 3 - 4 min then turned it back on, set the temp to 74° and the fan on high. The room started warming again finally... What is the best way to disable the FP if this happens again? Thank you for your time, Pat

How is Freeze Protection different from setting the mini split to its lowest heat setting of 62F?

Thanks for the video, though I seem to have found it later than most! Love the internet! I have an Amana unit in my sunroom in Northern Indiana and always wondered what this meant. My question: I don’t manually switch it into FP, this comes on automatically when it’s super cold outside. We turn the unit “off” at night before bed and sometimes this kicks on. Is it better to let this happen automatically or keep the heater function on at its lowest setting (low 60s). Seems like a waste if we aren’t in there.

Thank you!!!! You gave the info but make me laugh as an extra. Also, the posts below were helpful as I tried to set it at 60. It went to FP. Back in the old days I couldn't ask some random question like this and get informed.
