Smart Load Control (SLC) Function

(Fn14)
Smart Load Control Function could assist in reducing energy by low-
ering compressor lift during off-peak hours and shoulder seasons.
The function adjusts compressor lift by reading outdoor ambient
temperature, humidity (if FN16 is set to on), and current heating or
cooling demand in real time (rolling twenty [20] minute log).
Smart Load Control Options:
• Smooth Mode (oP1): Maximize energy savings; rate of temperature
change less important.
• Normal Mode (oP2): Balance the temperature change rate with the
energy consumed.
• Peak Mode (oP3): Quickly cool / heat the building; energy con-
sumption is less important.
All three (3) options only run for twenty (20) minutes of operation
after a compressor start. Following the twenty (20) minute morning
warm-up (or cool-down period), Smart Load Control will then use the
same algorithm irrelevant of which Smart Load Control option selected. If the outdoor unit is operating in cooling, Smart Load Control adjusts
the target low pressure; if the outdoor unit is operating in heating, Smart Load Control adjusts the target high pressure.
Smart Load Control can be used in almost every application except those where the outdoor unit is supporting a Dedicated Outdoor Air
System (contact an LG representative for information). Smart Load Control will not have an impact on operation if the system is running in
simultaneous cooling / heating (heat recovery systems only).
Use on both heat pump and heat recovery systems.
