※1 Password
It is necessary to input password to change or initialize parameters and default
value is "5". Be sure to take notes not to forget or loss it after changing
password.
※2 Setup max. and min. range of pressure sensor
Setup max. and min. range of pressure sensor. Pressure sensor is a ratiometric
type of 0.5~4.5V. Default value before shipment is 1~15bar.
※3 Setup pressure sensor offset correction
Users can input offset correction value for pressure sensor, temperature sensor
and input error. It was set 0.0 as a default value.
※4 Jerk control ratio
Limit value of motor speed variation (Jerk Control)
※5 Expansion valve compulsory open ratio
If users want to temporarily control expansion valve by designated open ratio
while controlling normally. Default value before shipment is OFF.

※6 Sensor filter input time
Only expert can setup this parameter. If sensor input is excessively unstable,
increase filter value and make it stable.
※7 EEV compulsory open ratio
It can be used to temporarily control electronic expansion valve with designated
open ratio when controlling normally.
Default value is set as not in use.
※8 Way to change of display mode
Press up / downward button to change parameters
(DIS parameter will be changed)
Parameter number will be displayed for one second before parameter is
displayed.
* It is possible to change with direct input when displaying superheat set point.
※9 Initialization
If password is entered, parameters will be initialized as an default value before
shipment.
