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.

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.
(a) The threshold value is decreased in accordance with the compressor frequency or indoor load (differences of
temperature).
