Diagram 0: Heating circuit with up to 2 heat sources
A1 = (S4 > min1 ) & (Heating = active)
If no room sensor is used, the room influence
RI
in menu
MIXER
must be set to zero and the
sensor
S1
in the
SENSOR
menu set to
FIXED VALUE (e.g. 20°C)
.
Program 0:
Enabling of heating circuit pump
A1
, when the sensor
S4
has exceeded the
minimum threshold
min1
.
If the sensor
S4
is not used, then it must
not
be switched to
OFF
.
To avoid the display "
999
" it is possible to allocate the sensor
S4
in the menu
SENSOR
a
fixed temperature, which must be higher than
min1
.
All pr1:
As program 0 however the heating circuit pump
A1
is also enabled by
sensor
S5
and minimum threshold
min2
(2 generators for the heating circuit).
A1 = ((S4 > min1 ) or (S5 > min2)) & (Heating = active)
