1. Features

1.1 The evaporator employs a Multi-bend structure which enlarges the heat exchange surface.

1.2 The front panel is tightly fixed with the front frame by simply buckling the latter with a buckle mechanism on the panel.

1.3 The manual force switch employs comfortable switch push buttons.

8.3.2 Protection is same as cooling mode.

8.4 Heating mode

8.4.1 Generally, the 4-way valve is open in heating mode, but it is closed in defrosting mode.

8.4.2 Generally, the outdoor fan is turned off with the on-off action of compressor in heating mode, except for the defrosting mode or the end of defrost.

8.4.3 Action conditions of compressor at heating mode: compressor must run for 4 minutes after starting and then judge temperature. Meanwhile other protections are still valid.

8.5 Defrosting mode

8.5.1 Conditions of defrost:

Defrosting starts when either of the following :

T3 lower than 0°c, lasts for more than 40 minutes, provided that the time period when the temperature is lower than -3°c consecutively reaches 3 minutes.

Calculate from the end of latest defrost, evaporator high temp. protection only closes outdoor fan with the compressor still running. Add up to 90 minutes

.

8.5.2 Conditions

Defrosting ends when either of the following :

The time gets to 10 minutes;

T3>20°c

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>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

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 Forced cooling Forced auto

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.

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 off, the buzzer buzzes lasts for 1 seconds, then A/C turns to be closedown status.

11

8.8.2. Forced Auto

8.8.2.1 Remote control signal can be received in forced auto mode. When receiving the signals, the forced auto mode will be canceled and the A/C changes to remote control status and performs operation as the signals indicates.

8.8.2.2 The system performs control according to the remote control auto mode with a set temperature of

24°c.

8.9 Timer

24 hours timer on or off.
