Specifications subject to change without notice.                                                                         SG-38MHRC-01

Indoor Fan Running Rules:

• In  the 

COOLING

 mode, the indoor fan runs continuously and the 

user can select any of the following speeds: 

HIGH

, 

MEDIUM

, 

LOW

 and 

AUTO

.

• When the setting temperature is reached, if the compressor stops 

running, the indoor fan motor runs in the minimum or setting 
speed (see Fig. 22).

Fig. 22 — Indoor Fan Running Rules

The 

AUTO

 fan adheres to the following rules (see Fig. 23):

Fig. 23 — AUTO FAN Running Rules

Compressor Temperature Protection

Fig. 24 — Compressor Temperature Protection

•

Off

: Compressor stops

•

Decrease

: Decrease the running frequency to the lower level

•

Hold

: Keep the current frequency

•

Resume

: No limitation for frequency

When the condenser temperature is higher than the setting value, the 
compressor stops.

Evaporator Temperature Protection

When the evaporator temperature is lower than the setting value the 
compressor stops.

HEATING Mode

Compressor Running Rules:

• When T1-Ts>-

T, the compressor stops.

• When T1-Ts<

T-1.5, the compressor is on. 

T is the programmed

parameter for temperature compensation.

• When the AC runs in 

MUTE

 mode, the compressor runs with a 

low frequency.

• When the current is more than the setting value, the current 

protection function activates and the compressor stops.

Outdoor Fan Running Rules:

The outdoor unit runs at a different fan speed according to T4. For 
different outdoor units, the fan speeds differ.
