AquaCal HP9 Retrofit Kit - STK0225-Currently on backorder from AquaCal, more are expected Late December, you can pre-order and we will ship the when they come in.

Salt pool guys is an awesome company to buy pool supplies from! Customer service is top notch! They care about their customers!

I ordered a new lcd display for my pool heater and paid the extra shipping to have it arrive earlier. It was supposed to arrive in 2 days but took 3. When I called the company to express my displeasure with the delay in the arrival of the product, I was refunded the amount that I paid. The product worked perfectly after installation and now my pool heater works again.

Ordering was easy and delivery is fast. I installed it myself. Wasn’t bad if you take your time. Had to make minor modifications on my unit. Mildly annoying but not bad. Salt Pool Guys have it figured out. Aquacal folks are pretty awesome as well if you find yourself in a pinch. All in all, a great and easy experience from order to install.

I had to modify the electrical enclosure a little and use a different model number but it was easy for me to do.

My older AquaCal pool heater had a 4-button display that stopped working. Replacement 4-button displays are either discontinued or impossible to find. I was not sure this kit would fit my heater. I also wanted to know if the upgrade would support a PoolSync in the future. SaltPoolGuys quickly answered my questions and even contacted AqualCal for me confirming this kit supports Poolsync. The kit includes everything needed including clear, easy to follow, printed instructions in the box as well as all operating and installer manuals. Additionally, AqualCal has posted a HP9 Retrofit installation video that makes the upgrade even easier.
