Hot Tub Wiring – Configuring a Balboa BP7 Spa Control 4.0kW Spa PackIf you are using a basic setup, and by basic I mean a regular dual speed hot tub pump with a single speed blower, out of the box, your Balboa pack is likely to work without any additional configuration. However, if you are not using a separate circulation pump, the chances are you will need to “configure” the pack using the details below. On the underside of the Spa Pack covers, you will see a circuit diagram that looks something like this. Firstly, you need to work through the setup table at the bottom on the left hand side and work out which setup number you need. For example, a 2 speed pump and a single speed blower will need setup #12. Next, you need to change the DIP switch settings to match your setup. Once you have the right combination of DIP switches, using the topside control you should do the following to change the pack’s setup mode to #12. To go into the low levels follow the following steps please.
- Turn tub off.
- DIP switch 1 move to ON.
- Turn tub on
- On the top side control, Press “WARM” twice
- Press “LIGHT”
- Press “WARM”
- Then use “WARM” to move down to the low levels until you get on the set up number you need.
- Turn off tub
- DIP switch one back to OFF
- Turn on tub
