Refrigerant data is in

2. Target superheat setting

Target superheat is in

3. Start open ratio and duration time

You can find it in

Now 26 kinds refrigerants is available in controller as below:

If the target SH is too small, may cause liquid hammer in compressor; if the target value is too large, the evaporator energy
efficiency will be very low.

When controller receives compressor RUN signal, EEV will keep the start opening ratio for the duration time.
