WARNING:
Wrongselection of refrigerant may cause damage to the compressor.
Startup Modes
Forced opening During startup
In some applications it is necessary to open the valve quickly when the compressor turns on, to prevent too low
suction pressure. This is ensured by setting a fixed opening degree and a startup time for the controller. Note that
this will give a fixed opening degree for the duration of the start time, regardless of the superheat value. Thesetting
parameters are called Start OD% (n17) and StartUp time (n15).

The controller is programmed for auto proportional control that will quickly Change the opening degree based
onthe superheat of the system. The proportional control is active during the Minimum start time set by the user,
and until the Super heat crosses the reference.
