(※1) When Return air (RS) is lower than –20˚C, defrost starts every 6 hours.
(※2) When "99" hours is selected, refer to on demand defrost in 2.5.3. (TR01-09A)
(※3) When Inside set point is –20.0˚C or Lower, In-range masking is 120min.
(※4) If defrost is initiated when inside temperature is out rangle area. (= In-range LED is not light), this condition is added to
finish defrost. Refer to "Defrosting termination" in 2.5.3. (TR01-09A)
(※5) Refer to "Fuse Protection table" in 7.11. (TR01-09A)
(※7) When dehumidification is ON in dehumidification mode, the setting figure may change between 900~2100kPa
automatically (Refer to "High Pressure Control" Page 2-17/TR01-09A)
