Daikin FDMRN20AV1KU concealed ceiling ducted split
The FDMRN20AV1KU / RR20AV1KU listing brings ducted cooling to rooms where the indoor equipment is concealed above the ceiling. Its catalogue model family, FDMRN20AV1K / RR20AV1K, provides 18,000 Btu/h of nominal T1 cooling with R-410A refrigerant and a rotary compressor. Air is distributed through a designed duct system to suit the space.

Controls and model-specific features
The series brochure describes Turbo, Sleep and Dry modes and illustrates the BRC51A62Y wired controller. Confirm the controller supplied with your order. Auto random restart resumes operation using the previous settings after a power interruption, with staggered restarting across units.
The FDMRN20–50 family includes the catalogue’s double drain-pan arrangement. The matched outdoor model uses a hydrophilic gold-fin coating on its copper-to-aluminium heat exchanger.
