Frequently Asked Questions
How do I know if the VS501Z is compatible with my hot tub?
The best way to confirm compatibility is to check the part number printed on your existing control board, or to send us your hot tub's make, model, and serial number. You can also email a photo of your current spa pak to fixmytub@gmail.com and our team will identify the correct replacement for you.
What voltage does the VS501Z operate on?
The VS501Z is a convertible system that operates at either 120V or 240V, making it suitable for most standard residential hot tub electrical configurations.
Does this system come with a heater?
Yes. The VS501Z includes a 4.0kW heater with two integrated sensors, so you won't need to purchase or install separate temperature or high-limit sensors.
Does the VS501Z come with a topside control panel?
This depends on the specific kit. Some configurations include a VL401 topside panel and overlay; others are sold as the control box only. Contact us at 1-855-248-0777 and we'll make sure you get the complete kit you need.
Is the VS501Z still in production?
Balboa has discontinued the VS501Z and is transitioning to the newer BP5 series (e.g., 50-BP5-500-55-K). We still carry VS501Z units while stock lasts. If the VS501Z is no longer available, we can help you source a compatible BP5 replacement.

Important Installation Notes
Circuit boards are not plug-and-play. Before installing, please note the following:
Correct component voltage setup is required — component wires on the board may need to be moved
DIP switches must be configured correctly for your system
Some configuration on the topside panel may also be required
Always reference the wiring schematics on the back of the spa pack cover
Do not select a board based on appearance — many boards look nearly identical but contain different software or chips
Electrical or physical damage resulting from improper installation voids the manufacturer's warranty
If you are unsure about any step of the installation process, we strongly recommend engaging a qualified spa technician.
Frequently Asked Questions
How do I know if this is the right circuit board for my hot tub?
The most reliable way to confirm compatibility is to match the Model Number from your spa control system's ID label — typically found on the top of the control box. You can also check the part numbers listed above or contact our team directly.
Can I send in photos to confirm the right part?
Absolutely. Email us at fixmytub@gmail.com with photos of your existing board, your hot tub's make and model, and the serial number. Our team will confirm whether this is the right replacement before you order.
Does this board come pre-configured?
Configuration options may be available depending on where you order. Contact us at 1-855-248-0777 to discuss your specific electrical setup, including your service voltage, pump configurations, and ozonator circuit requirements.
Can I return a circuit board if I order the wrong one?
Circuit boards are non-returnable electrical items, as they cannot be resold once handled. That's why we strongly encourage you to verify your part number or contact us before placing your order.
What warranty does this circuit board come with?

Important Installation Notes
Circuit boards are not plug-and-play. Before installing, please note the following:
Correct component voltage setup is required — component wires on the board may need to be moved
DIP switches must be configured correctly for your system
Some configuration on the topside panel may also be required
Always reference the wiring schematics on the back of the spa pack cover
Do not select a board based on appearance — many boards look nearly identical but contain different software or chips
Electrical or physical damage resulting from improper installation voids the manufacturer's warranty
If you are unsure about any step of the installation process, we strongly recommend engaging a qualified spa technician.
Frequently Asked Questions
How do I know if this is the right circuit board for my hot tub?
The most reliable way to confirm compatibility is to match the Model Number from your spa control system's ID label — typically found on the top of the control box. You can also check the part numbers listed above or contact our team directly.
Can I send in photos to confirm the right part?
Absolutely. Email us at fixmytub@gmail.com with photos of your existing board, your hot tub's make and model, and the serial number. Our team will confirm whether this is the right replacement before you order.
Does this board come pre-configured?
Configuration options may be available depending on where you order. Contact us at 1-855-248-0777 to discuss your specific electrical setup, including your service voltage, pump configurations, and ozonator circuit requirements.
