4) Condensation Temperature Control (cooling)
This system control is performed to limit the inverter frequency in order to restrict high pressure’s abnormal increase
and high-load operating prevention in the cooling mode.
In accordance with the temperature of the outdoor heat exchanger temperature sensors (C1, C2), such controls are
performed as to halting the operations of the indoor unit, decreasing the inverter frequency and restricting its increase,
etc.
(a) The threshold value is decreased in accordance with the compressor frequency or indoor load (differences of
temperature).
(b) When “X” values are lowered, the results basically become β=X-2, α=X-3.

5) Condensation Temperature Control (heating)
This system control is performed to limit the inverter frequency in order to restrict high pressure’s abnormal increase
and high-load operating prevention in the heating mode.
In accordance with the temperature of the indoor heat exchanger temperatures sensor (E1, E2), such controls are
performed as to halting the operations of the indoor unit, decreasing the inverter frequency and restricting its increase,
etc.
6) Cooling Freeze Prevention Control
The following control is performed during cooling operations (including dry mode operation), in accordance
with whichever of the indoor heat exchanger temperatures (E1 or E2) is lower. (See the chart below.)
7) Discharge Temperature Control
The following control is performed to prevent the discharge temperature from rising abnormally in order to protect
the inverter compressor.
In accordance with the temperature of the discharge sensor TD, such controls are performed as to limiting the
increase of inverter frequency, decreasing it or halting operation of the compressor.
* If the discharge temperature exceeds 101°C, operations of the compressor are halted and restarted after 3
minutes.
If this start/stop activity is repeated 4 times, the alarm “P03” (abnormal discharge temperature) occurs.
