Viessmann question

in THE MAIN WALL
What exactly does a 9543-421 telephone interface allow me to do and what will it do in a failure or alarm situation? Can I call it and diagnose the boiler? Can I use this to reset faults on the boiler? Under what circumstances will it call me or whatever number is selected? This will be going on a Vitodens.

    It will call you

    if there is ever a fault on the boiler, but only if you have the expansion board for the power and pump modual.
    It can also call out if the temp is too low in the space if you add in the room sensors. You can call up and change the control settings from normal opperation to an unoccupied
    preprogrmed setting, and viseversa. No resetting faults.
