NO, the timer windows are designed to control operation of the iStore to the desired period(s), during the timer window the iStore will “wake up” and review the internal tank temperature. Should the water require heating then the system will operate until the target temperature is reached.
Once the target temperature is reached the iStore will shutdown the heat cycle but will remain in an alert state observing the water temperature, should the water require heating again it will restart the heat cycle.
The timer OFF setting will override the heat cycle and move the iStore to the “sleep” or OFF state. No heating will take place outside of the timer window.
