■ Detailed information
•
This function is used with heat pump and heat recovery.
•
Heating, Cooling and Dry modes are a change in the setting impact.
•
The operating symptoms that might be corrected using this function
This feature does not correct adverse operating conditions. It is an energy enhancement feature.
ex) If outdoor setting is Op1(red line),
outdoor unit start operation slowly compared than basic operation but save energy during start-up
and after start up, discharge air temperature is automatically changed according to outdoor and
indoor temperature.
· Ask an authorized technician to setting a function.
•
Dual Sensing SLC is controlled by 3 factors. (in case of cooling operation)
-
1
st
: Outdoor temperature.
-
2

: 『Room temperature (T

-
Setting temperature (T

: Relative humidity (default : outdoor humidity)
(Refer to indoor humidity if we applied standard III remote controller inside)
■ Cooling Operation Logic
1. Outdoor temperature effect
•
The evaporation temperature of the indoor unit rises up to 9℃ according to the outdoor tem-
perature. where A is the indoor unit coil temperature.
① Out air temp. (35℃) → coil temp. of indoor unit is A [℃]
② Out air temp. (20℃) → coil temp. of indoor unit is A+9 [℃]
2. Room temperature (T
air
) - Setting temperature (T
target
)
•
In case of 35℃ (out air temp. condition)
& 1.5℃ ≤ Temp. gap (between room temp. and setting temp. ) ＜2.5℃
→ Target coil temp. of indoor unit is A
(where the relative humidity is between 50% and 70%)
