It does *not* mean that. Unfortunately, the mini splits do not have a
very
sophisticated control scheme. All the dehumidify mode means is that the
unit
cycles on and off on a fixed timer. It does not control temperature at
all
in
this mode. Mine runs for something like 7 minutes on, then 3 minutes
off.



thats not correct a correct statement, with the new Fujitsu mini-split
heat
pumps.... they use Variable frequency inverter drives and literally vary
their motor and compressor speeds for demand dehumidification without
turning the place into a walk in freeze box. The RLQ and RLS series
literally vary their output from 40% to 115% of their rated capacity
depending on demand.


Dat be some nifty ****.


I installed the 15RLQ system yesterday for a customer that is an EE... he is
like a kid with a new toy :-)

Got a 9RLS that I will be installing next week for another customer. (I
installed a 15RLQ in this guys shop last winter and he loves it. ) He closed
in his back porch/patio and wants another one. :-)
