When unit is in HEAT mode, after sleep mode has been set properly, the preset Tset will be increased by 1ć after the sleep program has run for 1 hour, and Tset will be decreased by another 1ć after 2 hours.Tset has been increased by 2ć totally in two hours Then the unit will run at this

temperature and at the set speed.

In Auto OR fan mode, the setting temp. will not change.

6.1.3.5 Toggle switch

1, If memory function is on, when unit is power-on and start operation and toggle switch is in STOP position, the unit will operates with STOP position; or

else unit starts under power-off memory. There is memory function with AUTO,RUN,STOP position. TEST position is without memory function.

2, If there is no memory function, unit will operate under previous switch position.

ƾ When toggle switch is on AUTO, unit operates in AUTO mode, and air swing on; if there is signal of remote control, then unit operates according to

signal.

ƾ When toggle switch is on TEST, indoor fan runs in high speed, and air swing on; indoor unit sends out signal of Cool mode on 16ć and 30ć

ambient temperature to outdoor unit. If malfunction of indoor or outdoor temp. sensor is detected, buzzer will give out beep to alarm. If there is signal of

remote control, unit operates as per remote control and indoor unit sends remote control signal to outdoor unit.

6.1.3.6 Communication failure

Communication failures happen if there is no correct signal received for 3 minutes

6.1.3.7 Buzzer control

When unit is power on or receiving remote control signal or the toggle switch is pressed, the buzzer will give out a beep.

6.1.3.8 Power-off memory function

1) contents of memory: mode(AUTO, COOL, DEHUMIDIFYING, HEATING, etc), setting fan speed, setting temperature, Timing etc.

2) if unit was on when power off, 3 minutes is delayed for indoor unit to send signal of starting to outdoor unit.

3) When power is on again, unit will operate in previous mode before power-off.

4) If there was no timer function in the last remote control dictation, then unit will memorize the last remote control dictation and operate according to

the previous mode

5) If there was timer function in the last remote control dictation and system was power-off before the time set, unit will memorize the last timer function

and it will time from the begin of restarting.

6) If there was timer function in the last remote control dictation and system was power-off at the time set, unit will operate in the mode before

power-off but timer won’t be on.

6.1.3.9 Failure detect of indoor temp. sensor

When unit is defrosting, temp sensor malfunction is not under detection. In other status temp sensor malfunction of indoor ambient and tube are

under malfunction. If the temperature is not between the minimum and maximum for continuous 30s, signal of error will be sent out.

When indoor temp sensor failures, it will send signal of closing down unit to outdoor unit.
