We have been working on introducing a new version of the multi-functional timer. The new version (release on 02/2019) have a number of new functions. We introduced power independent function where the timer can be used to track the usage of various equipment. Once you set the duration the timer starts the countdown and once countdown gets to 0 the output turns On to indicate the equipment service is required. The uniqueness of this feature lays in timer's ability to save the intermittent countdown into the internal memory. The countdown is not reset when power is removed. It stops for a period of the power outage and continues after power is restored. It could be used to indicate equipment maintenance periods, filter replacements and etc.
