off periods per day, via the Technical Settings (see installation
instructions) .

the unit is designed to eliminate the possibility of accidental
changes to your programme. Buttons normally visible, only
affect your set programme temporarily. All buttons which can
permanently change your programme are located behind the
flip over facia.
