Mode two:Temperature compensation value adjustment mode for dehumidifying
o o
Press WARMER/COOLER button can increase or decreased temperature compensation value for 1 F (or C). The range for indoor
ambient temperature compensation value is -6~+6 o F (-3~+3 o C) (Dry mode LED is bright).
Mode three: Adjusting mode for cooling temperature offset
o o o o
WARMER button can increase offset fset temperature 1 F(or C). while COOLER button can decrease offset temperature 1 F(or C).
o o
The indoor ambient temperature offset adjusting range is -6 to +6 F(-3 to +3 C) (cooling mode LED is bright)
Mode four: Adjusting mode for heating temperature offset
o o o o
WARMER button can increase offset temperature 1 F(or C), while COOLER button can decrease offset temperature 1 F(or C). The
o o
indoor ambient temperature offset adjusting range is -6 to +6 F(-3 to +3 C) (heating mode LED is bright)
The temperature offset is default 0 in dry mode, cooling and heating mode. They can allocate different offset in dry mode, cooling
and heating mode respectively. The offset cant be adjusted in fan mode.
Mode five: Display switchover between setting temperature and ambient temperature in heating and cooling mode;
Press the WARMER button or COOLER button to switch the setting temperature and ambient temperature displaying;
Setting temperature displaying: the dual 8 displays SP. After quitting configuration mode, the heating mode, the cooling mode and the
dry mode display the set temperature constantly;
Ambient temperature displaying: dual 8 displays AA. After quitting the configuration mode, the heating mode, the cooling mode and
the dry mode display the ambient temperature.
As for below circumstances, it will display set temperature for 10s and then turn to display ambient temperature. (Note: if ambient
temperature displaying is set, when turn on the unit in cooling mode, heating mode or dry mode, timer will be displayed for 5s, then
turn to display set temperature for 5s and then turn to display ambient temperature.)
a. Press mode button
b. Energization after power failure
c. Restart the unit
d. Turn on the unit after EM turn off unit
e. Adjust the set temperature by WARMER OR COOLER button
Mode six: switchover between allowing emergent cooling auto start-up and not allowing emergent cooling auto start-up.
Press WARMER OR COOLING to switchover between allowing emergent cooling auto start-up and not allowing emergent cooling
auto start-up.
Allowing emergent cooling auto start-up: dual 8 displays CA.
Not allowing emergent cooling auto start-up: dual 8 displays Cd.
Method for quitting configuration mode: as for the above configuration modes, they will be quitted by pressing the mode button or
when there is no action within 30s.
Memory function
Energizing after power failure, the controller is running according to the status before power failure.
Restore factory settings
In standby and OFF status, after pressing "fan speed" + "WARMER" for 3s and the dual 8 displays "00" for 3s (do not display others),
it shows that the factory settings has been restored. Meanwhile, the configuration information is default to display.
Fahrenheit and not allow emergent cooling auto start-up. Heating offset, cooling offset and dry offset is 0 and the set temperature is
o
displayed. T value is 0, the fan speed is medium, the set temperature is 71 F and timer is canceled.
