shows that the pump is running and at which current speed (rpm). Power consumption in Watts (W) is shown for that
particular speed.
Timer setting
Running the pump at different speeds at different times of the day will minimise energy consumption when higher speeds are not
needed and can allow the user to take advantage of lower electricity tariffs, for example during the night.
In order to benefit from this, the iSaver+ allows the setting of up to 4 timers. These are established as follows.
Step 1: Press
