Explain Filter Timing?

Electronic boards have a built in filter cycle. On most Jacuzzi spa boards, there is a built in default of 2 hours twice a day. So, when you power up, the board considers that "0" hour. It will first for the next 2 hours and then 12 hours later, again for 2 hours.

Example: You turn main power on at 8:30 in the morning. Now 8:30 both AM and PM, the spa will filter for 2 hours. Note: if house current ever goes off, it will reset again to whenever the power is turned on again.

On some boards you can manually use a jumper to increase the filter length to 5 hours. Usually, this is not a good idea.

On Platinum Series, you can program the board to filter any length of time using the topside to program the board.

One Note: Its best to set the filter cycle early AM during the summer. Spas tend to overheat if the filter cycle is in mid day.

Also.... very often, customer THINK the spa is running all the time. They check in when going to work (say 7 am) and when they get home... about the same time. They THINK it was on all the time. To see if it actually was one filtering during those times, I suggest turning the main power off say 10pm. Wait a minute. Turn power on. The default will be 10-12 am/pm. If the spa IS on when you check those other times and its NOT heating, then you likely DO have a board failure problem.
