3 FUNCTION
Function Description
Memory function when unit restart after power off, it will run on former status, the mode and
parameter are kept the same
Remote control function wireless controller and remote controller can be opted, and the maximum
control distance of remote controller is 10m.
Timing function it can timing ON/ OFF separately, meanwhile, it can also can timing on
circularly
Self-diagnosis with alarm
function
once unit has malfunction, the malfunction code will be indicated and
alarm ring immediately
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 Week 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 weekly timer has the function of
invalidating the lower unit. The weekly timing 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 that 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 and display malfunction code
Anti-high
temperature protection
once the heat exchanger temperature of indoor unit is too high,
compressor stop and unit display malfunction code.
Timing ON/OFF display display and timing turn ON/OFF time
Fan speed display display the speed (high.medium.low) of fan
Function model display cooling mode.dehumidifying mode.heating mode.fan mode
Testing display display testing mode
Temperature display display room temperature and set temperature
