Selector switch
The selector switch has 16 different positions. Each position has two functions (e.g. switch
position
min2 / T2 ). The value, which is nearer to the selector switch, will be displayed with-
out pressing of the yellow key “
Eingabe
” (e.g.
T2
). By pressing the yellow key “
Eingabe
” (=
“input”) the second value will be displayed (e.g.
min2
). The blue keys “
ab
” (= “down”) resp.
“
auf
” (= “up”) change the settings. Holding the key pressed increases resp. decreases con-
stantly the value, short taps cause a change of 1.
The interior legend (e.g. T5 = displayed temperature of outdoor sensor 5) has no direct
connection to the outside legend (e.g. diff1 = difference between 2 sensors).
T1 - T6 Actual temperature of the sensors
min1,2
The minimal threshold min generally prevents boilers from being
clogged with soot. The hysteresis has an increasing effect, i.e. reaching
the threshold plus hysteresis the output will switch on, falling below the
threshold it will switch off. Factory setting (ex works =
ew ): min1 = 60°C,
min2 = 30°C; setting range: 0 to 150 °C
max
The maximum function limits the storage of tanks. The hysteresis has a
decreasing effect, i.e. reaching the threshold the output will switch off,
falling below the threshold minus hysteresis it will switch on again;
ew : 70 °C; setting range: 0 to 150 °C
diff1,2
The output will be released, when the temperature difference between
two set sensors exceeds this value. Normal set value: approx. 5K. The
hysteresis has an increasing effect, i.e. reaching the temperature differ-
ence plus hysteresis the output will switch on, falling below the differ-
ence it will switch off;
ew : diff1 and diff2 5.0 K; setting range: 0 to 99 K
