(6)  Compressor pre-start control (Master unit/slave unit)

(a)  The following control is performed when the compressor ON conditions are established.

(i)  Pre-start control when the operation mode is same as previous operation mode:

1)  In case of "Cooling /Dehumidifying" mode, 4-way valve is turned OFF. In case of "Heating" mode, 4-way

 

valve 

is turned ON.

 

However if the operation mode is same as previous operation mode and 4-way valve is retaing prescribed condi

-

tion, the control status of 4-way valve is unchanged.

2)  Solenoide valve SV6 and SV7 are turned ON.
3)  The opening degree of EEVH1, 2 for heating and EEVSC for subcooling coil are set to the initial opening degree 

mentioned in following table. The expansion valves EEVH1, 2 are operated first, and after those operations are 
completed, the expansion valve EEVSC will be operated.

 

Note  (1) Expansion valves of master unit and slave unit are operated respectively. 

4)  Fan motors FMo1, FMo2 and compressor start 15 seconds after the compressor ON conditions are satisfied.
