Electrical Control Function
1.3.6.2 Timer on. The machine will turn on automatically when reaching the setting time.
1.3.6.3 Timer off. The machine will turn off automatically when reaching the setting time.
1.3.6.4 Timer on/off. T
1.3.6.5 Timer off/on. T , and then
1.3.6.6 The timer function will not change the AC current operation mode. Suppose AC is off now, it will not
start up firstly after setting the timer off function. And when reaching the setting time, the timer LED will be
off and the AC running mode has not been changed.
For high static pressure duct & cassette: The timer function will change the AC current operation mode.
e AC will turn on firstly and then turn off when
reaching the setting time.
1.3.6.7 The setting time is relative time.
1.3.7 Economy function
1.3.7.1 It is valid in cooling, heating and auto mode.
1.3.7.2. Turning off, changing mode or setting fan speed will cancel economy function.
1.3.7.3 Operation process in sleep mode is as follow:
After pressing ECONOMIC or SLEEP button on the controller, the machine will go into economy mode.
When cooling, the setting temperature rises 1 (be lower than 30 ) every hour, 2 hours later the setting
temperature stops rising.
For heat pump models, when they are in heating, the setting temperature reduces 1 (be higher than 17 )
every hour, 2 hours later the setting temperature stops reducing.
1.3.7.4 In this mode, the fan speed is forced into AUTO mode.
1.3.8 Auto-Restart function
The indoor unit is equipped with auto-restart function, which is carried out through an auto-restart module. In
case of a sudden power failure, the module memorizes the setting conditions before the power failure. The
unit will resume the previous operation setting (not including Swing function) automatically after 3 minutes
when power returns.
1.3.9 Drain pump control(For duct & Cassette)
1.3.9.1 Water level check
The water lever will be checked every 5 seconds, if the feedback signal is abnormal, it will be considered as
drain water full by the control system.
1.3.9.2 Drain pump control
If there is no water full error, the drain pump will be on when the unit is in cooling mode (including
auto-cooling and forced cooling) and dry mode. It will be off when the unit is in heating mode, fan only mode
or off state (if the pump is on before the unit is off, it will delay 3 minutes to be off).
If there is a water full error, the drain pump will be on when the error occurs. Afterwards:
