10 Turn clockwise once again to the next time
that you require a period with lowering tem-
perature to begin., e.g. 22:30.
11 Press the button.
12 Turn forward to make settings for the fol-
lowing weekday, and continue until you have
made period settings for all seven weekdays.

(00.00), it changes over to the next weekday.
13 Finally, hold the button for 3 seconds to
save your settings and nish. e display will
automatically return to normal display.
With Devireg™ 550 you only have to pro-
gramme the time when you want comfort
temperature and the time you want economy
temperature. e thermostat will do the rest. You
do not have to calculate when the heating should
start; Devireg™ 550 will do this for you.
Please note: If at any point a mistake is made,
rotate the dial anticlockwise to the rst segment
and press the button to clear the markers.
