Thanks to this box the backwash of your filter will start by itself. It comes with a 220 V mains adapter and also works with three AA batteries that will take over if there is a power cut. The batteries also allow you to retain the settings.
An easy-to-set automatic filter
The control buttons on the box are simple and ergonomic:
The display switches itself off after 5 seconds to save energy. Simply press the round button at the bottom to reactivate it
The central "drain" button is used to manually trigger a backwash.
Pressing the "set" touch button alternately selects the trigger cycle in days "d" and the number of seconds "S" for the backwash duration. Adjustments are then made using the "+" and "-"
The auto button sets the cycle to 15 days by default and 15 seconds of backwash.
The setting range for the backwash trigger cycle is 1 to 99 days. The backwash time is adjustable in ranges of 15 seconds up to 90.
