🔆 Large-format LED panel with Jets, Blower, Light & Temp controls for versatile spa management
⚠️ DISCONTINUED BY BALBOA – Please use TS-VL407 when stock runs out.
💧 Product Overview
The Balboa VL406T Topside Control Panel is a large-format control interface designed for Balboa GS Series, Duplex control systems, Touch Spas, and Canadian Spa hot tubs. With its 178 mm × 86 mm design and 4-button interface, this panel provides comprehensive spa control with the added benefit of a bright LED display for enhanced visibility in all lighting conditions.
Featuring a basic 3-digit LED display, the VL406T offers control of four key spa functions: Jets, Blower, Light, and Temp. Operating at 12V, this panel supports single pump operation plus 1 blower/auxiliary output, and connects via a telephone cord style connector for easy installation.
This is the generic version commonly used by Canadian Spa. In Canadian Spa hot tubs, the single jets button is used to operate 2 pumps. In spas without a blower, the blower button would simply be inactive, or the topside sticker can be changed to reflect the actual configuration. The VL406T is also compatible with GS500, GS500Z, GS501, GS501Z, Duplex control systems, and Touch Spas.
Please note: This product has been discontinued by Balboa. When current stock is depleted, please use the replacement model TS-VL407.

Balboa BP Spa Packs
If you have a “BP” spa pack, you will find the name and model on the label, then you can use any of the “TP” range of topside controls, TP400, TP600 etc etc.
You can also use any of the “Spa Touch” graphical controllers on your Spa Pack. Spa Touch comes in versions 1-3 with 4 to be released very soon as well as the new “mini”.
The BP Spa Pack made things nice and easy so when you are replacing your topside control with one of these, it is straight forward enough.
Balboa VS & GS Spa Packs.
If you have an older hot tub that you are keeping alive with new parts, then the chances are you have an older spa pack in there too. This is where it gets a little more complicated in terms of compatibility.
Two of the popular models are the VS which stands for Value Series and was supplied to a lot of OEMs (manufacturers for hot tubs) to go into their tubs. Likewise, the GS (global series) was the same. Lots of different rebranded options, different names, but at the heart of things are these two packs.
What is key on these two models, is the combination of letters and numbers that make up the model number on the Spa Pack.
The VL range of topside controls was designed for both of these spa pack ranges; however, there are some “rules” we need to abide by in terms of compatibility.
VL Panels ending in D work with VS/GS systems ending in DZ
VL Panels ending in S work with VS/GS systems ending in SZ
The rest of the VL Panels work with VS/GS systems ending in Z (not SZ or DZ)
For example, a Spa Pack model VS501SZ would work nicely with a Topside that is model VL620S. However, that same topside control would not work with a spa pack model VS501Z. The connections are the same, it would plug in, but would not respond at all.
Another example, a Balboa GS500Z spa pack would work with the VL406T or the VL401 but would not work with the VL702S.
You get the patters. Topside ends in S or D, matches to Spa Pack ending in SZ (for S) or DZ (for D).
Balboa EL & GL Spa Packs
Before the birth of the BP range, the EL and GL Spa Packs did have some level of standardisation in terms of the topside controls.
All of the “ML” range of Balboa Topside Controls are designed to work with the EL and GL range of spa packs. They actually look very similar to the TP range, they just have a different type of connection to plug into the Spa Pack.
VL Panels ending in S work with VS/GS systems ending in SZ
The rest of the VL Panels work with VS/GS systems ending in Z (not SZ or DZ)
