￿If Yes is chosen, the pump asks the user whether the remote stop feature is to be disabled fully (for both manual and auto operation), or only for manual operation, leaving remote stop functioning when the pump is operating in auto mode. Choose using the UP and DOWN keys and press ENTER to confirm. If manual and auto was chosen, the pump briefly displays a confirmation screen (an example is shown here) and returns the user to the third screen of the Setup menu. If manual only was chosen, the pump asks the user to make a further choice, according to whether the pump (with remote control available in auto mode only) is required to run on an open or closed remote switch: Open=stop or Open=run. Choose using the UP and DOWN keys and press ENTER to confirm. The pump briefly displays a confirmation screen (an exam- ple is shown here) and returns the user to the third screen of the Setup menu.

￿Note: The confirmation screen indicates whether Remote stop is enabled or disabled, and displays the command sense of the remote control switch even if Remote stop has been disabled.

Even with the remote stop function disabled, the pump could still start if the remote auto/manual toggle input is used to toggle the pump into analogue mode.

Alternatively ...

￿To toggle the sense of the remote run / stop control between open=stop and open=run: stop the pump. Turn off the mains power switch at the rear of the pump.

￿Hold down the STOP key and the DIRECTION key, and turn on the mains power switch.
