Timer on, Timer off and sleep control are available.
2.3 Dehumidifying mode: (Tr: inlet air temperature,Ts£º the set temperature)
The background lighting of the LCD is aquamarine blue
Temperature control range : 16¡æ¡ª 30¡æ
Temperature control precision: ±1¡æ
control character:
When Tr (indoor temperature) > Ts (temperature setting) +2¡æ, compressor and
outdoor fan motor run continuosly with indoor fan motor runnig in accordance with
the wind speed setting.
When Tr ranges from Ts to Ts +2¡æ, outdoor fan motor and compressor are on for
10 minutes and off for 6 minutes, the indoor fan motor is off in 3 minutes after
shutdown of compressor and gives breeze in other time.
When Tr < Ts, outdoor fan motor and compressor are unavailable, and the indoor
fan motor enter breeze mode 3 minutes later after shut down of compressor.
When all the ranges alternate, there is ¡À1¡æ difference.
Wind speed control:
Automation: When Tr >= Ts + 5¡æ, the wind speed is high.
When Ts+3¡æ≤ Tr <Ts+5¡æ, the wind speed is medium.
When Ts+2¡æ≤ Tr <Ts+3¡æ, the wind speed is low.
When Ts≤ Tr <Ts+2¡æ, the machine gives breeze intermittently.
When Tr < Ts, the indoor fan motor is shut off. in 3 minutes
When Tr < Ts, the machine gives breeze after 3 minutes
Manual operation: When the temperation sensor is off or the Indoor fan motor runs
intermittently, the indoor fan motor can not be operated by hand (compelling
automatic operation), along with the indoor fan motor can be operated in cooling
mode. While controlling fan motor by hand in cooling mode, the cooling ranges
include wind speed setting and refriferation range, others are the same as fan motor in
automation mode.
compressor control£º The compressor can't be controlled by temperature sensor in 2
minutes after
startup and also can't be started again at least 3 minutes later after shutdown. There
are 3-minutes protection with power on for the first time (over 3 minutes with
power off). The compressor must be started again 3 minutes later after shutdown.
There is no 2-minutes limit when changing the temperature setting or shutting off the
machine
through the remote controller, and the machine can be shut down immediately.
Avoiding electrical shock: outdoor fan motor is available 2 seconds later after compressor
startup.
Controlling the position of air door: set the position of air door as required.
Protection of frost is available (disable in test run or heating mode): In order to prevent the
indoor heat
exchanger from freezing (in refrigation or dehumidifying mode), the compressor
will be shut off when the temperature of the indoor coil pipe is or below 0¡æ and
the compressor runs for over 5 minutes. When the temperature of the indoor
