Connecting the Nidec Neptune pump requires connecting the wires from A(+), B(-) and GND from the pump drive to the D+, D- and GND connectors respectively on one of the four communication bus terminals located on The Attendant controller (labeled BUS1 – BUS4).
See the following diagram:
| Nidec Drive | Attendant BUS Port |
| A+ | D+ |
| B- | D- |
| GND | GND |
Once you have the communication wires in place, you need to place the pump into Remote Mode.
- Press the MENU/ENTER button once to enter Navigation Mode.
- Press Scroll Up or Scroll Down to select the Standard Settings menu tree.
- Press MENU/ENTER to enter the menu tree.
- Press Scroll Down until you reach the Remote Control screen.
- Press MENU/ENTER again to enter Input Mode.
- Press Scroll Up or Scroll Down to toggle the setting.
- Press MENU/ENTER to save the changes.
- Press START/PAUSE to exit the menu option and return to the menu tree in Navigation Mode.
- After exiting the menu tree, the control enters remote mode automatically.
Pumps Using a Gecko Controls Board

The procedure to disconnect this board is as follows:
- Disconnect all power to the pump.
- Open the display cover using the appropriate tools.
- Disconnect the RS485 cabling from the Gecko Controls board by loosening the small screws on the blue terminal block.
- Remove the single Philips screw
- Lift the board straight up and away from the main pump control board
- Replace the blue terminal block onto the main pump control board
- Reconnect the RS485 cabling to the blue terminal block
- Connect the display cover back onto the pump
- Turn on the power to the pump
Take Pump out of Remote Mode
If Remote Mode is enabled, follow these steps to return control of the pump to the UI.
1. Press the Speed 2 and Speed 3 buttons simultaneously and hold them down for five seconds. Note: If a button press is not detected in ten (10) seconds, the UI reverts to Remote Mode.
2. Press MENU/ENTER to save the changes and return to Navigation Mode. After confirming the change, the pump stops, if it is running, and initially moves to Standby Mode. The pump will no longer respond to commands from the external control system. If a programmed flow is scheduled to run at this time, it will restart the motor at the programmed flow speed. Otherwise, it will remain in Standby Mode. Other options, for example timed flow programming, can be accessed.
