Now let’s program the breaker settings. Press and hold the light key (for about 20 seconds) until you reach the breaker settings menu. The filter cycle duration menu will come up first. Keep holding the light key down until you reach the breaker settings menu which will appear as b.24.

The values displayed by the system correspond to 80% of the maximum amperage capacity of the GFCI. Use the Up or Down keys to choose the desired value. For example: If you are using a 15A breaker, select b.12. If you are using a 20A breaker, select b.16. If you are using a 50A breaker, select b.40. In this case we are using a 15A breaker, which means we will select b.12. Press the light key to set the breaker rating.
