i have my units set for 14 degrees frost and 20 degree in warm mode

given an avg. RH of 65 i will just stay clear of mold...

but if RH goes to 69 it says i will get mold within 236 days...

now that does not take in to account that i have vent slots on top of all
my windows except the door to the balcony and the small window in bath...
bath have a hole connected to the building vent that runs 24/7 same does
the exhaust over the stove...

so i will not have an issue, but i can only imagine how fast things would
happen in an unventilated house with low heat
