Balboa Water Group VS501Z Control System 54220-Z

Shipping was quick and it arrived in a sturdy packaging. The controller / heater was the correct type, so I was able to replace the old unit without issues. This type is designed to accommodate 110V as well as 220V. Default configuration is 110V, so I needed to re-configure to 220V to match my setup before turning on power. This is an easy process of changing 3 jumper wires on the electronic board to match the connections present on the old board. It turned on and both pumps and the heater work as expected.

Spa pack works great, had it installed last week. Hopefully it lasts longer than the original one!

"Made my spa brand new!! Thanks guys!!"
