To determine the board you need for your spa, turn off all power to the spa and look for a number printed on your existing board. It should match up to one of the part numbers listed below.

Note: Most Hydroquip 120/220 Volt Universal systems use a 120 Volt board.

Note: The last 2 digits indicate the latest revision (board update). For example, your part number may be 33-0014A-R5. The latest board update (33-0014A-R8) will work to replace older versions.
