Each correction

 

• (Each gas pipe temperature thermistor - Minimum gas pipe temperature thermistor) 1

• (Main indoor coil thermistor - Sub indoor coil thermistor)

1 Perform this, when number of operation units is 2 units or more. MXZ-2A20NA-1 , MXZ-3A30NA-1 and MXZ-4A36NAare excluded.

2 Correct the LEV opening by discharge temperature.

(1)LEV opening correction by discharge temperature

The target discharge temperature is determined according to frequency zone and number of operation unit of the com- pressor.
