*1. If the thermistor is not connected or has a broken wire, −99.9 is displayed.
*2.
With the default setting, 0 is displayed. Note that display is enabled when parameter n020 is “1” or the optional communication expansion board is installed.
*3. This is the value obtained by rough calculation under the following conditions (the error is around 20%): power supply voltage of
200 V, pump discharge pressure of 0.2 MPa (VG32: oil temperature 25℃). Contact us separately about pumpless units.
