Frequently asked questions

How do I know which control panel to order?

The most accurate way to order is to look at the part number on your existing control panel (usually found on a sticker underneath the unit) or the part number on the overlay sticker. Do not rely solely on the shape, as many panels look similar but have different button configurations (e.g., Jets 1 vs. Blower).

What is the difference between the panel and the overlay?

The panel is the electronic unit with the screen and circuit board that plugs into your spa pack. The overlay is the sticky label on top that tells you what the buttons do. If your buttons work but the label is peeled, you only need an overlay. If the buttons are unresponsive or the screen is blank, you likely need the full panel.

Do you sell the Cal Spas ATS controls?

Yes, we carry the specific auxiliary panels for the Cal Spas Adjustable Therapy System (ATS). These are the smaller control units often located near specific seats in the spa.

Can I install these parts myself?

Most topside panels are "plug and play." They connect to the spa's circuit board using a specific style of plug (often a phone-style jack or a molex plug). However, always ensure the power to the hot tub is turned off at the breaker before attempting any repairs.
