Similar to manual polling, the pump cleaning function can be triggered only when the VFD is in
stopped state. To enable the pump cleaning function, set the terminal function to 86, enable the
terminal, and send a startup signal.
After the pump cleaning function is enabled, all water pumps are cleared in order. Then the VFD
automatically stops. During pump cleaning, you can terminate the pump cleaning by sending a stop
command. If you want to restart pump cleaning after pump cleaning is completed or terminated, you
need to send a stop command.
