0: Fixed variable-frequency pump mode
Inverter 3-phase output control a certain pump as fixed variable-frequency pump, other pumps
power-frequency run/stop controlled by programmable D0 output. (max control 1*fixed
variable-frequency pump+4*power-frequency pumps), power-frequency pump conform to “start first
stop first”. Under this mode, 4*power-frequency pumps corresponding to No.2~5 pumps, according to
the specific site situation requirements for the numbers of power-frequency pumps, which can be
achieved by set multi-functions input (51~54) and H00.11, for more details please refer to H00.11
instructions. Wirings refer to Figure 3-1.
