(WPEVKQPCPF%QPVTQN
When turning on the unit each time, the swing blade must be open to angle 5 (mini position), and then compressor, fan etc. can run.
When switching on controller or turning off the unit each time, the swing blade must be at OFF status.
4. Buzzer
Upon energization or operation, the buzzer will give out pleasant sound (digital chord).
5. Auto Fan Speed Control of Indoor fan
In auto fan speed, indoor fan will select high, medium or low fan speed automatically according to the change of ambient temper ature.
For the switchover between any two kinds of fan speed, the unit must be make sure that it has run at each fan speed for 3mins and 30s
at least.
6. AIR Function
˄
it’s reserved for some models
˅
AIR function is invalid when the unit is turned off. Upon receiving the order for starting up AIR function from remote controller or control
panel, indoor fan will be turned on and the AIR function will be started up; once receiving the order for turning off AIR function, AIR
function will be turned off. After the unit is turned off, AIR function will be cleared automatically.
7. X-FAN function
X-FAN function can be turned on/off by the FUNCTION button on control panel or X-FAN E-HEATER button on remote controller.
If start up X-FAN function in cooling or dry mode, after the unit is turned off, indoor unit will still run for a few minutes to dry the water
inside the unit, and then the indoor unit will be turned off automatically.
8. Turbo Function
In cooling and heating mode, turbo function can be turned on/off (there’s no turbo function in auto, dry and fan mode) by the turbo button
After pressing turbo button for once, remote controller will display the characters of “turbo” and fan speed won’t change, Meanwhile,
indoor fan will run at super-high fan speed and display panel will display the super-high fan speed; After repressing turbo button, the
turbo function will be quitted and the characters of “turbo” on remote controller will be disappeared. Meanwhile, indoor fan will turn back
to setting fan speed. Super-high fan speed will also be quitted after operating the fan speed button and the fan speed will also be
changed correspondingly. Display panel will display the setting fan speed.
Turbo function is default to be turned off when remote controller is energized.
When restarting up the unit or switching the mode, turbo function will be memorized.
When restarting up the unit by remote controller and controller or switch to cooling or heating mode, turbo function will be memorized.
While when switching to auto, dry or fan mode, the turbo function is unavailable.
9. Power-off Memory Function
When re-energizating the unit after power failure, the unit will run at the memory content. Memory content : mode, up&down swing
(7kinds of status), right and left swing (7 kinds of status), setting temperature, setting fan speed, light, timer, turbo, AIR, health and
environment mode.
If the unit is at ON status after power failure, compressor will be started up 3mins delayed after energization; if the unit is at OFF status,
compressor will be started up without 3mins delayed.
If the timer hasn’t been reached before power failure, the unit will time again according to the setting timer before power failure.
5 Protective Measures
When cooling in cooling mode or dry mode (that’s Tamb>2
ć
), if it’s detected that the evaporator tube temperature is too low
the system will turn to antifreezing protection status. Meanwhile, compressor and outdoor fan will stop running, while indoor fan and
swing motor will keep original status. When evaporator tube temperature resumes to normal range and compressor has stopped for
6mins, controller will run at the setting mode.
Buttons won’t be shielded during the antifreezing protection.
When the high-pressure protection is detected for 3s successively, all loads will be turned off. Meanwhile, all buttons and signal will be
shielded and E1 will be displayed. When it’s detected that the high-pressure protection of compressor has been released for 6s
successively, the shield for button and signal will be released and E1 will still be displayed. E1 can be cleared after pressing ON/OFF
button to turn off the unit. The unit will resume running after repressing ON/OFF button.
This function is unavailable for some modes. But if the controller is the general controller and the shielded wire of low-pressur
protection is loosened or not connected well, it will take it as low-pressure protection by mistake. The details are as below:
1. After compressor is started up for 2mins, it will begin to detect the signal of low pressure switch. If it’s detected that the low pressure
switch is broken for 1mins successively, the complete unit will stop running. 3mins later, if the low pressure switch is resumed, the unit
will resume running automatically. If low pressure switch protection occurs for 2 times successively, E3 will be displayed and the
can’t resume running automatically to warn users that it’s leaking. After restarting up the unit and low pressure switch is resumed, the
unit will resume running.
1. Indoor antifreezing protection
2. High-pressure protection of system
3. Low-voltage protection of system
