Even if the battery capacity is too low to run a program, if the valve is open it will be closed.

The battery voltage is tested during the opening and the closing pulse. In this way you can test the capability of the battery at any time. To do this, press two times the On/Off-man. key. If the valve closes and the Batt. indicator does not appear then the battery is functioning. If the display disappears and only the Batt. indicator appears, the battery has to be changed.

Previously set data is lost when replacing the battery. AProgram the Water Timer subsequently again.

For notes on changing the battery see “Inserting the Battery”.
