when unit restarts after power off, it will run on former status, the mode and
parameter are kept the same
wireless controller and remote controller can be selected, and the maximum
control distance of remote controller is 10m.
it can timing ON/ OFF separately, meanwhile, it can also timing on circularly
Once the unit has malfunction, the malfunction code will be indicated and alarm
rings immediately
it can self control for saving energy in energy saving mode.
the fan of indoor unit can adjust fan speed automatically based on actual
demand when cooling or heating under automatic mode
the fan starts only when the temperature of indoor unit heat exchanger is higher
than indoor temperature under heating mode
Centralized Control and Weekly Timer Functions: The centralized controller and
the weekly timer are integrated in the same wire controller. The system has both
the centralized control and the week timing functions. Up to 16 sets of units can

function is able to realized four timing ON/OFF periods for any unit every day, so
as to achieve fully automatic operation. No timing control can be set for holidays.
when suction pressure is too low or discharge pressure is too high, compressor
will stop and unit display malfunction code
compressor has its own overheat protection.Once the temperature of
compressor is higher than allowable level, compressor will stop and only when
temperature recovery, compressor restart
once the current of compressor is higher than normal level, compressor will stop
and unit display malfunction code
once the discharge temperature of compressor is higher than allowable value,
compressor will stop and unit display malfunction code
once the phase sequence of power supply is incongruent or the phase is absent,
unit can't work.
once the heat exchanger temperature of indoor unit is too high, the outdoor fan
motor will stop.
