The device has a function for determining the heat quantity. It is deactivated ex works.
A heat quantity meter fundamentally requires three details. These are:
flow temperature, return temperature, flow rate (volume flow)
Furthermore in order to increase the accuracy it is necessary to specify the frost protection
share in the heat transfer medium since the frost protection reduces its heat-transporting
capacity. The flow rate can be made as a direct entry or via an additional sensor with speci-
fied pulse rate.
ON/OFF
Heat quantity meter activate/deactivate (fs = OFF)
SSL
Sensor input of flow temperature (fs = S4)
Setting range: S1 to S6 Input of the flow sensor
E1 to E9 Value from external sensor via DL
SRL
Sensor input of return temperature (fs = S5)
Setting range: S1 to S6 Input of the return sensor
E1 to E9 Value from external sensor via DL
VSG
Sensor input for volume flow encoder. (fs = --)
The pulse encoder
VSG
can only be connected to input S6. For this purpose the fol-
lowing settings must be made in the
SENSOR
menu without fail:
S6 VSG
Volume flow sensor with pulse encoder
LPP
Litres per pulse
Setting range: VSG S6 = volume flow encoder
at input 6
.
VSG E1 to E9 = Value from external sensor
via DL-Bus
VSG -- = no 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
V V
olume flow in litres per hour. Without a volume flow encoder a fixed volume flow
can be set in this menu. If the set output is not active the volume flow is assumed
to be 0 litres/hour. Since an activated speed control always results in other volume
flows this procedure is not suitable together with the speed control. (fs = 50 l/h)
Setting range: 0 to 20000 litres/hour in 10 litre/hour increments
OP
Assigned
o
ut
p
uts. 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).
(fs = --)
Setting range:
OP = -- heat quantity is calculated without any consideration to the
outputs.
Combinations of all outputs (e.g. OP1, OP23, OP123)
SA
Frost protection share of the heat transfer medium. An average is calculated from
the product information of all relevant manufacturers and implemented in the form of
a table according to mixing ratios. Under typical conditions this method results in an
additional maximum error of one percent. (fs = 0%)
Setting range: 0 to 100% in 1% increments
