The controller is battery-powered. To save power and thus
extend the working life of the batteries, the display is nor-
mally switched off. If you press one of the selection but-
tons or turn the rotary knob, the backlighting switches on
and the basic display appears. At this point, you have not
changed any settings. Only if you press one of the selec-
tion buttons or turn the rotary knob when the display is
switched on are the settings changed.
The basic display shows the current settings and values of
the heating installation. If you make a setting on the con-
troller, the display on the screen switches from the basic
display to the display for the new setting.
The backlighting goes out approx. 10 seconds after the last
operation. The display switches off approx. 1 minute after
the last operation.
