Timing function
it can timing ON/ OFF separately, meanwhile, it can also timing on circularly
Self-diagnosis with
alarm function
Once the unit has malfunction, the malfunction code will be indicated and alarm

Sleep function it can self control for saving energy in energy saving mode.
Automatic function
the fan of indoor unit can adjust fan speed automatically based on actual
demand when cooling or heating under automatic mode
Cool air proof function
the fan starts only when the temperature of indoor unit heat exchanger is higher
than indoor temperature under heating mode
Weekly Time
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
be controlled simultaneously by the centralized controller (weekly timer). The

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.
High/low pressure
protection
when suction pressure is too low or discharge pressure is too high, compressor
will stop and unit display malfunction code
Overload protection
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
Over current protection
once the current of compressor is higher than normal level, compressor will stop
and unit display malfunction code
Discharge high
temperature protection
once the discharge temperature of compressor is higher than allowable value,
compressor will stop and unit display malfunction code
Reverse (open) phase
protection
once the phase sequence of power supply is incongruent or the phase is absent,
unit can’t work.
Anti-high temperature
protection
once the heat exchanger temperature of indoor unit is too high, compressor will
stop.
