Hot Tub Wiring – Configuring a Balboa BP7 Spa Control 4.0kW Spa Pack

If 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.

1. Turn tub off.
2. DIP switch 1 move to ON.
3. Turn tub on
4. On the top side control, Press “WARM” twice
5. Press “LIGHT”
6. Press “WARM”
7. Then use “WARM” to move down to the low levels until you get on the set up number you need.
8. Turn off tub
9. DIP switch one back to OFF
10. Turn on tub

Getting the right setup and config is important for the pack to function correctly and the buttons on the top side to do what you expect them to.

 

Balboa DIP Switches Explained

Most of the Balboa Spa Packs have a set of DIP switches that can seem a little confusing in the setup. In the most basic form, you are telling the Spa Pack how many pumps or blowers you have connected and how many it should allow to run before it turns off the heater (or let them all run at once). The reason for this is if you are limiting the amount of current the pack can draw. You are also telling the pack wither you need additional cool down times if you are using an gas/propane/ASHP additional heater. This to stop the kettling effect you can get in the heaters.

Check the circuit diagram that is on the inside of your Balboa pack and do not just copy the settings I explain below as they may be in a different order. The “logic” behind them is the same so just check what each of the DIP switches says it does.

Fixed-fuction DIP Switches 

A1 Test Mode (normally Off). 

A2 In “ON” position, add one high-speed pump (or blower) with Heater. (If you have 1 pump and NO blower use this)

A3 In “ON” position, add two high-speed pumps (or 1 HS Pump and Blower) with Heater. (If you have a pump and a blower use this)

A4 In “ON” position, add four high-speed pumps (or 3 HS Pumps and Blower) with Heater. (If you have two or three pumps and a blower use this)

You should only enable one of the A2, A3 or A4. You can use them in combinations, but it is easier just to use one.

A5 In “ON” position, enables Special Amperage Rule B.  In “OFF” position, enables Special Amperage Rule A. 

Special Amperage Rule A No Limitation (if you are not sure, set it to this. Worst case, your electric will trip if you don’t have enough current available)

Special Amperage Rule B 2 High Speed Pump Maximum, in Setups 1 – 9 1 High Speed Pump Maximum, and also Blower turns off with 1 High Speed Pump, in Setups 10 – 18 (avoid this if you can)

A6 Persistent memory reset (Used when the spa is powering up to restore factory settings as determined by software configuration). 

A2, A3, and A4 work in combination to determine the number of high-speed devices and blowers that can run before the heat is disabled. i.e. A2 and A3 in the ON position and A4 in the OFF position will allow the heater to operate with up to 3 high‑speed pumps (or two HS Pumps and Blower) running at the same time. Heat is disabled when the fourth high-speed pump or blower is turned on. 

Note: A2/A3/A4 all off = No heat with any high-speed pump or blower. 

Assignable DIP Switches 

A7 In “ON” position, enables a 5-minute cooldown for some gas heaters (Cooling Time B). In “OFF” position, enables a 1-minute cooldown for electric heaters (Cooling Time A).
