Balboa VS Series Spa System full feature system for newer spa pack replacement. Require 1 1/2" plumbing and a minimum flow rate of 25 GPM. Replaces Costco # 55098
Was easy to drop in this replacement control. All I had to do was match the dip switchs to the old unit and confirm the pump voltages and it worked perfectly. Cant beat the pricing and fast shipping of Canada Hot Tub Parts. Thanks
