Expansion Valve Compulsory Control
* Bias : Initial control output value of expansion valve (expansion valve open ratio at point which setting superheat value is equal to current superheat value).
* Proportional Band : Initial control range value of expansion valve (when setting superheat is 6.0K and proportional band is 5.0K, it can be controlled within range of
3.5K(0%) ~ 8.5K(100%)) - Please increase proportional band if width of vibration of superheat value is large.
* Integral Time : It controls open ratio of expansion valve by accumulating error each integral time - increase integral time if cycle of vibration of superheat value is short.
* Derivative Time : It is used in circumstance where It needs instant response. Generally setting value is '0'.
* Low Superheat Alarm : Input low superheat alarm value. It closes valve until become control lower limit value of expansion valve if superheat is lower than low superheat alarm value.
* High Superheat Alarm : Input high superheat alarm value. It opens valve until become control upper limit value of expansion valve if superheat is higher than high superheat alarm value.
* Pressure Lower Limit Alarm : It opens expansion valve to 100% if suction pressure is lower than pressure lower limit alarm.
* Pressure Higher Limit Alarm : It closes expansion valve to 0% if suction pressure is higher than pressure upper limit alarm.
* Expansion Valve Control Upper Limit : Setup maximum open ratio of expansion valve (but, It opens valve to 100% regardless of upper limit value if pressure lower limit alarm occurs.)
* Expansion Valve Control Lower Limit : Setup minimum open ratio of expansion valve (but, It closes valve to 0% regardless of lower limit value if pressure upper limit alarm occurs.)
* No Response Control Range : Keep open ratio of expansion valve if superheat is controlled within setting superheat +/- (no response control range).
* Operation Delay Time : Start to control after setup delay time if there is operation start input.
* Expansion Valve Manual Control : It is used when user compulsorily controls expansion valve at open ratio which is set by user. compulsory control function is not used if setup is OFF.

* Minimum Valve ON Time : It makes compulsorily valve ON during setup time if it needs control for period which is shorter than setup time when controlling valve ON/OFF.
This function do not work when setup is OFF.
* Expansion Valve Control Cycle : Setup control cycle of ON/OFF type expansion valve. Setup 6 sec. for AKV series of Danfoss.
* Output when Sensor Error : Setup output ratio of expansion valve to output compulsorily when temperature or pressure sensor error occurs.
* Expansion Valve Control Slope : Input control various value of expansion valve to increase or decrease per second. It is used when rapid control is needed.
* Display Mode : Display in order Superheat --> Temperature --> suction pressure when rotation mode.
