(10) Display

Operation pattern and mode pattern display

All the display patterns will display for a time when the unit is powered on, the operation indication icon will display in red under standby status. When the machine is start by remote controller, the indication icon will light and display the current operation mode (the mode light includes: Cooling, heating and dry). If you close the light key, all the display icons

will close.

Double-8 display

According to the different setting of remote control, the nixie lamp may display the current temperature (the temperature scope is from 61°F to 86°F) and indoor ambient temperature. The heating and air supply temperature will display 77°F under auto-mode, the temperature will display 64F under the heating mode, and the temperature will display H1 under the defrosting mode.(If you set the fahrenheit temperature display, the nixie lamp will display according to fahrenheit temperature)

(11) Protection function and failure display

E2:

Freeze-proofing protection

E4: Exhausting protection E5: Overcurrent protection

E6:

Communication failure

E8: Overload protection

F1: Indoor ambient sensor start and short circuit (continuously measured failure in 30S)

F2: Indoor evaporator sensor start and shortcircuit (continuously measured failure in 30S)

F3: Outdoor ambient sensor start and short circuit (continuously measured failure in 30S)

F2: Outdoor condenser sensor start and short circuit (continuously measured failure in 30S, and don’t measure within 10 minutes after defrosted)

F5: Outdoor exhausting sensor start and short circuit (continuously measured failure in 30S after the compressor operated 3

minutes)

 

H3: Overload protection of compressor

H5: Module protection

PH: High-voltage protection

PL: Low-voltage protection

P1: Nominal cooling and heating

P2: Maximum cooling and heating

P3: Medium cooling and heating

P0: Minimum cooling and heating

(12) Drying Function

 

You may start or stop the dry function under the modes of cooling and dry at the starting status (The modes of automatism, heating and air supply do not have dry function). When you start the dry function, after stop the machine by pressing the switch button, you should keep running the infoor fans for 10 minutes under low air damper (The swing will operate as the former status within 10 minutes, and other load is stopped), then stop the entire machine; When you stop the dry function, press the switch button will stop the machine directly.

When you start the drying function, operating the drying button will stop the inner fans and close the guide louver.

(13) Memory function wheninterrupting the power supply

Memory content: mode, swing function, light, set temperature and wind speed.

After interrupted the power supply, the machine will start when recovering the power according to the memory content automatically. If the last remote control command has not set the timed function, the system will remember the last remote control command and operate according it. If the last remote control command has set timed function and the power supply is interrupted before the timed time, the system will remember the timed function of the last remote control command, the timed time will recounted form power on. If the last remote control command has set timed function, the time is out and the system is start or stop according to the set time when the power supply is interrupted, the system will remember the operation status before the power supply was interrupted, and do not carry out timed action; The timed clock will not be remembered.
