temperature and Ts means setting temperature.

Select running mode according to the following conditions at the first time to enter Auto mode:

TrıTs-3ć to select cooling mode (with setting temperature being Ts +3)

Tr˘Ts-3ć to select heating mode (with setting temperature being Ts)

After the system entering auto run mode, the running mode can convert automatically

according to variation of room temperature between cooling and heating. If the unit is in cooling

mode, when the temperature arrives stop value, the compressor stops; the system will measure the

temperature after compressor stops for 3 minutes. At this time, if Tr˘Ts-3ć, the unit will enter

heating mode, or it will still be cooling mode. If the unit is in heating mode, when the temperature

arrives stop value, the compressor stops; the system will measure the temperature after

compressor stops for 3 minutes. At this time, if Tr˘Ts+3ć, the unit will enter cooling mode, or it will

still be heating mode.

If the unit is in heating mode, when indoor heat exchanger temperature is over 63ć, the unit

will turn into cooling mode automatically, in 1 hour, the indoor heat exchanger temperature will not

be limited, and heating operation will stop temporarily, 1 hour later, the system will adjust the

working mode due to the above conditions.

If the unit is in heating mode for the first time, compressor motor will start up, within 8 minutes the

system will not measure indoor ambient temperature, the remote controller will be off.

2). Single Cooling type

Select running mode according to the following conditions at the first time to enter Auto mode:

TrıTs+3ć to select cooling mode

Tr˘Ts-3ć to select blowing mode

After entering Auto mode, the operation mode can be changed between cooling mode and fan

mode according to indoor ambient temperature: if the unit now is in cooling mode, when Tr˘Ts-3,

the mode will be changed to Fan; if the unit is in Fan mode, when TrıTs+3, the mode will be

changed to cooling mode.

3. COOL mode control

4-way valve being powered off, compressor run/stop will depends on the temperature

difference between the room temperature and the set temperature.

TrıTs+1 compressor will run;

TrİTs-1 compressor will stop;

Ts-1<Tr<Ts+1 compressor will stay in original state

Anti-freezed protection

When the unit has run for over 6 minutes after compressor starts up, if indoor coil temperature

Tg<1ć last 1 minute, the compressor and the outdoor motor will stop; 9 minutes later after

compressor stops and when indoor coil temperature rises to 10ć, the compressor and the outdoor

motor will run again.
