to disable climate control on the R32 is easy.
you hold down the hot or cold button until it maxes out (ie.. 18 or 32) then it'll hit FC (forced cold or f**kin cold, whichever you prefer) or FH (forced heat or f**kin hot). Then you can use the fan button to vary the speed of the fan as it auto defaults to full fan speed too.
if you just want the fan to go on and not engage the climate control, then switch it off (nothing on the screen) then press the fan button. It'll turn just the fan on and blow whatever's outside thru or cycle whatever's inside.
you'll also notice that if you don't turn anything on, a steady stream of air trickles through. if you want to turn it off, then while its off, just press the recirculate button, and there'll be no air movement at all thru the system.
hope that helps... if your climate control isn't workin properly then its most likely that flap... sometimes its easy to fix yourself if its just jammed... I might post a DIY on how to lubricate/clean the lever assembly. I gotta clean my aircon filter this weekend.
