Balboa Water Group VS510SZ Control System 54218-Z

I did a lot of research to replace my circuit board, numerous places gave me prices for just the circuit board which was more than replacing the whole control. Emailed David at SpaCare.com with a few pictures and within 15 minutes he determined what I needed and I ordered it. Showed up in two days! I can't thank the enough for such great service. Excellent product, a direct fit into my old system.

"These people are very helpful. I received the unit fine. It was a replacement for a unit in an Emerald Spa that was about 15+ years old. I was sitting in the hot tub the next night with a glass of wine in my hands. I would buy it again!"

"Replace my old system at a lower cost with updated technology. Well worth the money!!"

"Most bang for the buck when replacing an outdated control system."

"First I have to say Dave in product support is top notch. He walked me through replacing my old unit. The new unit arrived and was installed promptly and works well."

"Very easy to install works great"

"Very easy to navigate sight and found what I was looking for."

Balboa controller arrived in a timely fashion in good shape. Installation was straightforward and easy even with wiring changes. Product installed for a 2 weeks now and working well.

Changing from a pressure switch to a flow parameter heater has caused me to redesign the circ pump plumbing. To archive the required flow rate thru the heater, I will need to increase the flow out of the heater tube by adding a direct feed to the spa from the heater.. In my case I'm looking at adding a waterfall to the circ system.

Great customer service to decide on correct part and if I should replace bad board or complete unit. I made the correct choice. Bought complete heater unit. Quick shipping and plugged in perfect. Installed in about 15 minutes! Very happy ??

I have a very old Leisure Spa Celebrity.... It would not keep temperature, I replaced the Board once before... But after a couple quick emails with David, He suggested the VS510SZ as a replacement. Installed it in about 1/2 hour... and Worked like a charm.

Very fast delivery and easy to install.
