Power failure
In the event of a power failure, the program will remain stored in the NOVRAM® during an undefined period, while
an incorporated SuperCap (capacitor) will maintain the correct time of day during a period of several hours;
consequently, in case of prolonged power failure, the time of day might not be maintained; if this happens, the time
of day indication will
flash when the power supply is re-established, indicating that the time of day needs to be set.
When the power failure occurs during the execution of an automatic regeneration, the control valve will
immediately return to the service position; when the power supply is re-established, the control valve will stay in the
service position for 60 sec. and restart a complete regeneration from the beginning.

In such case, entering one of the programming levels can possibly solve the problem. However if the problem
persists, professional service is required.
