In case of 35℃ (out air temp. condition)
- High humidity condition (RH 70 ~ 100%)
: Target coil temp. is lower than the standard humidity condition (RH 50~70%)

It is the function to set whether to use the humidity sensor. The outdoor unit considers the current outdoor
ambient humidity condition when making adjustments to the control values of the refrigeration cycle.

■ Detailed information
•
The humidity sensor's real time reporting of the outdoor ambient humidity level is used in the Ad-
vanced Smart Load Control (FN14), Comfort Cooling (ID10), and Intelligent Defrost - Smart Heating
(core logic) to prepare the system for changes in the building load.
•
This function is used with heat pump and heat recovery.
•
Heating, Cooling and Dry modes is a change in the setting impact.
•
Cooling / Heating operation by using humidity sensor (Option "on")
- When used cooling operation of SLC function, it will improve energy efficiency because evapora-
tion temperature will be decreased
- When used heating operation in case of high humidity condition, deforest will be delayed because
target high/low pressure will be changed.
