the compressor still running. Add up to 90 minutes

8.5.2 Conditions of defrost ending:
Defrosting ends when either of the following :
The time gets to 10 minutes;
T3>20°c
8.5.3 Time sequence of the whole defrosting procedure is as follows:
Compressor
4-way Valve
Outdoor Fan
Indoor Fan
Remark: when the evaporator pipe sensor temp. more than TE16, The indoor fan start to run.
8.6 Auto mode
8.6.1 When running in automatic mode, the air conditioner automatically selects one of the following
operation modes: cooling, heating or ventilation according to the difference between room temp. (TA)
and set temp. (TS).
TA—TS
TA—TS>2
-1 ≤TA—TS≤+2
TA—TS<-1
8.6.2 At auto mode, the indoor fan blows automatically in selected mode.
8.6.3 One mode should be carried out for at least 15 minutes once selected. If the compressor cannot start
for 15 minutes, reselect the operation mode according to the room temp. and set temp., or reselect
when the setting temp. changed
8.7 Economic mode
Cooling: The set temperature rise 1 per hour. Two hours later, the set temperature will maintain as a
constant and the air circulation is kept at low speed,and the air condition will stop work after 7 hours.
Heating: The set temperature decrease 1
maintain as a constant and the air circulation is kept at low speed, and the air condition will stop work
after 7 hours. (Cold air proof function takes priority over all).
8.8 Manual operation
Manual operation is controlled by touching buttons and divided into force cooling and
forced auto mode. It transfers between these two modes by pressing the buttons, the
cycling order of the button press is:
Remote mode
8.8.1 Forced Cooling
8.8.1.1 In forced cooling mode, the remote signal is not accepted.
8.8.1.2 The compressor is unconditionally turned on, after 30 minutes cooling operation whose fan mode is
set as low, the A/C operates in the forced auto mode under the requirements of the forced auto
mode.
