Power-Selection (
)
This function is used when the circuit breaker is shared with other electrical
appliances. It limits the maximum current and power consumption to 100%,
75%, or 50% and can be implemented by POWER-SELECTION. The lower
percentage, the higher saving and also longer compressor lifetime.
Note:
• When the level is selected, POWER-SEL level flashes on remote LCD
display for 3 seconds.
In case of 75% and 50% level, number “75” or “50” also flashes for 2
seconds.
• Due to the reason that POWER-SELECTION function limits the
maximum current, inadequate cooling or heating capacity may occur.
Silent Operation (
)
Keep outdoor unit operating silently to ensure either yourself or neighborhood
will have a tight sleep in nighttime. By this feature, the heating capacity will
be optimized to deliver such silent experience. The silent operation can be
selected from one of two purposes (Silent 1 and Silent 2).
There are three setting parameters: Standard level > Silent 1 > Silent 2
Silent 1:
Though operating silently, the Heating (or Cooling) capacity is still prioritized to
ensure having sufficient comfort inside the room.
This setting is a perfect balance between the Heating (or Cooling) capacity
and the Sound level of outdoor unit.
Silent 2:
Compromising the Heating (or Cooling) capacity to the Sound level in any
circumstance where the outdoor unit’s sound level is highly prioritized.
This setting has a purpose to reduce the maximum sound level of outdoor unit
by 4 dB(A).
Note:
• While activating of Silent operation, inadequate heating (or cooling)
capacity may occur.
