Heaters and Chillers
Ports to connect to on The Attendant: BUS1 – BUS4
Ports to connect to on The Attendant Mini: BUS1 – BUS2
These devices should only be powered directly from the power center or breaker panel. Do not run electricity through a relay as The Attendant will control the device to turn on/off by using the communication cable.
The instructions below apply to Heat Pumps with a display that is pictured below:
Serial RS-485 Connection (Recommended)
The recommended connection mode for AquaCal heat pumps utilizes Serial RS-485 wiring. This connection enables The Attendant to switch between heating and cooling modes on heat pumps equipped with this capability.
- Turn off power to the heat pump and The Attendant
- Remove electrical access panel on the heat pump
- Route 22 gauge 2 conductor wire from The Attendant enclosure into the low voltage compartment of the heat pump.
- Connect wires to “Port B” of the control board in the heat pump
- Connect the other end of the wire to a Bus port on The Attendant
| Aquacal HeatPump | The Attendant |
| Pin A (Port B) | D+ |
| Pin B (Port B) | D- |
Once the wiring is completed you must put the heat pump into remote mode:
Depending on the heat pump model or how it was previous configured, you might be prompted to enter an “ENTRY CODE.”
If this happens, try “17” as this is the manufacturer default.
- Wake up the unit by swiping across the keypad
- Press Menu
- Use arrows to navigate to System and press Enter
- Use arrows to navigate to Advanced and press Enter
- Use arrows to navigate to External Control and press Enter
- Use arrows to pick External Control Mode and press Enter
- Use arrows to select SMART and press Enter.
- Use arrows to set the Local Address. Select 00, and press enter when done. [When configuring this device using the Poolside mobile app, you will enter 1 as the Bus Identifier.]
- Confirm OK to clear existing setups.
The heat pump should restart when the procedure is complete. You should see the following screen:
NOTE
If you see SMART COMM FAULT on your heat pump display there is an issue with your wiring or configuration on The Attendant
Troubleshooting
If the heat pump displays a “SMART COMM FAULT”:
- Confirm wiring – Confirm wires are oriented properly on the heat pump’s “Port B” of the control board.
- Deactivate power to heat pump and the Attendant.
- Remove the access panel on the heat pump.
- Reverse wires on “Port B”.
- Reinstall electrical access panel.
- Reactivate power to the Attendant.
- Reactivate power to the heat pump.
