8.5.3 Time sequence of the whole defrosting procedure is as follows:
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 Operation mode
TA—TS>2℃ Cooling
-1 ≤TA℃ —TS≤+2℃ Air-only
TA—TS<-1℃ Heating (air-only for cooling only type)
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.
Heating: The set temperature decrease 1 per hour. Two hours later, the set temperature will ℃
maintain as a constant and the air circulation is kept at low speed (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:
8.8.1 Forced Cooling
Remote mode Forced auto 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.
8.8.1.3 During the start-up and operation, all of the following protecting functions work:
3minutes start-up delay protection, overload protection, outdoor protection, evaporator
Protection against low temperature. If any of the protection functions, the comparative protecting
action is executed.
The forced cooling mode is closed by one touch on the button, meanwhile the operation light is
