With this function, e. g. a valve can be controlled in parallel
to the pump via a separate relay PARRE.
If solar loading takes place (R1 and/or R2) or if a solar
function is active, the relay selected will be energised. The
parallel relay can also be energised inversely (INVER).
Parallel relay
OPARR / PARRE
Parallel relay
Adjustment range 2, 3, 4
Factory setting:
system-dependent
Note:
If R1 and/or R2 are in the manual mode, the se-
lected parallel relay will not be energised.
Heat quantity measurement
OHQM
Heat quantity measurement
Adjustment range: ON / OFF
Factory setting: OFF
The heat quantity measurement can be carried out in 3
different ways (see below): without fl owmeter V40, with
fl owmeter V40 or with Grundfos sensor.
Î
Enable the heat quantity measurement option in the
channel OHQM.
Î
Select the type of fl ow rate detection in the channel
FTYPE.
OHQM / FTYPE
Flow rate detection type
Selection: 1, 2, 3
Factory setting
: 1
Flow rate detection type:
1 : fi xed fl ow rate value
2 : V40
3 : VFS sensor
OHQM / FMAX
Flow rate
Adjustment range
:
0,5... 100.0 l/min
in steps of 0.1 l/min
Factory setting
: 6.0 l/min
OHQM / MEDT
Heat transfer fl uid
Adjustment range
: 0...3
Factory setting
: 1
Heat quantity measurement with fi xed fl ow rate
value
The heat quantity measurement calculation (estimation)
uses the difference between fl ow and return temperature
and the entered fl ow rate (at 100 % pump speed).
Î
Adjust 1 in the channel FTYPE
Î
Read the fl ow rate (l/min) and adjust it in the channel
FMAX.
Î
Adjust the antifreeze type and concentration of the heat
transfer fl uid in the channels MEDT and MED%.
Note:
Type 3 can only be selected if the Grundfos sen-
sors have been activated in the channel GFDS.
Note:
FMAX cannot be selected in systems with 2
solar pumps (ARR 6, 7, 17, 18, 19, 20, 21, 22, 23,
24, 25, 26).
