When using Vortex sensors without DL connection the supply can be made from one of
the control outputs. For this purpose the appropriate control output must be set to 5 V.

VSG
Sensor input for volume flow encoder (ex works = --)
The pulse encoder
VSG
can only be connected to input S6. For this purpose the
following settings must be made in the
SENSOR
menu without fail:
S6 VSG
volume flow sensor with pulse encoder
LPI
Litres per pulse
Setting range: VSG S6 = volume flow encoder

fixed volume flow. For the
calculation of the heat amount, the set volume flow is only used if
the set output is active

olume flow in litres per hour. If no volume flow encoder has been set, a fixed
volume flow can be preset in this menu. If a set output is not active, the volume
flow is assumed to be 0 litres/hour.
As activated speed control can produce constant changes in volume flow, this
method is not suited to use with speed control. (ex works = 50 l/h)
Setting range: 0 to 20000 litres/hour in increments of 10 litre/hour
OP
Assigned outputs. The set/measured volume flow is only used to calculate the
heat quantity if the output specified here is active (or at least one of several
outputs). (ex works = --)
With pump-valve systems, the allocated outputs must be adjusted according
to the basic diagram (e.g. with program 49: OP 12)
Setting range: OP = -- heat quantity is calculated without any consideration to the
outputs.
Combinations of all outputs (e.g. OP 1, OP 23, OP 123)

ntifreeze in the heat transfer medium. An average has been calculated
from the product specifications of all of the major manufacturers; this average is
used in the table of mixing ratios. This method generally produces an additional
maximum error of one percent. (ex works = 0%)
Setting range: 0 to 100% in increments of 1%
