5-4 Dry Mode Operation
Dry operation remove moisture from indoor air running, in cooling mode, at a low level without reducing the
ambient temperature. This is done cycling ON and OFF indoor and outdoor units according to below.
ROOM DRY LEVEL
TEMP
≥ SPT+2°C LEVEL 0
Operation according to COOLING mode
CM on
< SPT+2°C LEVEL 1 FMO on
≥ SPT-1°C FMI switches between L and LL (30 seconds)
RV off
CM switches 9 minutes off and 3 minutes on
< SPT-1°C LEVEL 2 FMO switches 9 minutes off and 3 minutes ON
≥ 15°C FMI switches off and L during CM operation

SPT = Set Point Temperature
5-5 Fan Mode Operation
With this mode, the indoor fan is turned on while CM, FMO and RV stay off all the time. The user can select
between 3 speeds: HIGH, MEDIUM and LOW.
5-6 Auto Fan speed
With this option selected, the indoor fan speed changes automatically according to the difference between
the detected air temperature (RAT sensor) and the set point (SPT):
COOLING MODE
2 ≤ (RAT – SPT):
HIGH speed
1 ≤ (RAT – SPT) < 2: MEDIUM speed
(RAT – SPT) < 1: LOW speed
HEATING MODE
2 ≤ (SPT - RAT):
HIGH speed
(SPT - RAT) < 2: MEDIUM speed
NOTE
SPT = Set Point Temperature
