Pump Trial Operation: This parameter is used for system debugging and is effective only when
F8--00 ≠ 0 and the pump is shut down. Set Parameter F8-37, enter the command and you will
enter the testing status. If the variable-frequency circulator pump is subject to line frequency trial
operation, the pump will be directly switched to line frequency. For a variable-frequency
circulator pump, variable frequency/line frequency trial operation can be conducted to confirm if
the rotation direction is uniform. If a line frequency operation is required, you must confirm that
the rotation directions of line-frequency operation and variable-frequency operation are uniform.
