13. Operation Control (For Multi Split Connection)

During multi split connection, indoor unit’s operation controls are same with single split connection unless specified in
this chapter.

13.1 Cooling

operation

13.1.1 Thermostat

control

Capability supply to indoor unit is OFF (Expansion valve closed) when Intake Air Temperature — Internal setting

temperature < -2.0°C.

Capability resume supply to indoor unit after waiting for 3 minutes, if the Intake Air temperature — Internal setting

temperature > Capability supply OFF point.

13.2 Soft Dry Operation

13.2.1 Thermostat

control

Capability supply to indoor unit is OFF (Expansion valve closed) when Intake Air Temperature

—

Internal setting

temperature < -3.0°C.

Capability resume to indoor unit after waiting for 3 minutes, if the Intake Air temperature

—

Internal setting

temperature > Capability supply OFF point.

13.3 Heating

Operation

13.3.1 Thermostat

control

Capability supply to indoor unit is OFF (Expansion valve closed) when Intake Air Temperature

—

Internal setting

temperature > +1.0°C.

During this condition, the indoor fan is stopped if compressor is ON.

Capability resume supply to indoor unit after waiting for 3 minutes, if the Intake Air Temperature

—

Internal

setting temperature < Capability supply OFF point.

13.3.2

Temperature Sampling Control

Temperature sampling is controlled by outdoor unit where room temperature for all power supply ON indoor unit

could be obtained.

When capability supply to the indoor unit is OFF and the compressor is ON, the indoor fan motor is stopped.

During this condition, 15 seconds after sampling signal from outdoor unit is received, the indoor fan start
operation at low fan speed.

However, within first 4 minutes of capability stopped supply to the indoor unit, even sampling signal is received,

the sampling control is cancelled.
