Parameter Description
Suction HP for Sets the suction pressure for
speed rise limit indoor fan speed rise limit.
Suction HP for Sets the suction pressure for
speed fall forcibly decreasing the indoor
fan rotational speed.
Suction LP for Sets the suction pressure for
shutdown shutting down the compressor.
Suction LP for Sets the suction pressure for
shutdown automatically starting the
recovery compressor after the
compressor is shut down.
Anti-freeze press Sets the suction pressure for
for freq rise lim compressor freq rise limit to
avoid frost.
Anti-freeze press Sets the suction pressure limit
for freq fall
for preventing the freeze of
pipes. When the pressure is
lower than the value, the
compressor frequency begins
to decrease.
Anti-freeze press Sets the suction pressure limit
for shutdown for preventing the freeze of
pipes. When the pressure is
lower than the value, the
compressor will be shut down.
Anti-freeze Indicates the time delay for
shutdown delay shutting down the compressor
when the detected suction
pressure reaches the value for
shutting down the compressor.
Phase cur for Sets the current for compressor
freq rise limit freq rise limit.
Phase cur for Sets the phase current for
freq fall forcibly decreasing the
compressor frequency.
Phase cur for Sets the phase current for
shutdown shutting down the compressor.
Anti-cond freq When the supply air
fall temp diff temperature is lower than the
calculated dew-point
temperature at the return air
side, condensation may occur.
To avoid condensation, the
frequency of the compressor
should be forcibly decreased
