The MK3 control has memorized 3 more functioning
modes:
d = Dehumidifying

The “D- Dehumidifying” mode permits to
keep the air-conditioner running making
cooling cycles of 30 minutes every 6 hours.
This mode permits to keep the humidity

quick defrosting cycles every 30 minutes. This
works only with RC reverse cycle models. While in
heat mode the AF mode rises the minimum fan
