I only recommend it because if you have a Tri-Chlor with a buggered LED display, it is cheaper to buy this product than to replace the entire controller. It's not good value because you have to buy the entire circuit board when only the LED display is malfunctioning. The LED display only lasts a couple of years before it starts to malfunction and the batteries on the circuit board are too small and have to be replaced too frequently which is a PITA. A decent battery e.g. an RS PRO 3.6V NiMH would work much better.

Replaced the old PCB with this new generation card and works like a dream with improved features and functions including actual PH reading and ability to reduce chlorine production to zero. An important change is the ability to continue chlorine production even when the with the 'LOW SALT' alarm has been activated.
