Menu 9.1.4 Sub shunt
Here the sub shunt is set either On or Off. The
factory setting is Off.
Menu 3.1 Curve slope 2
The selected curve slope for the heating curve
is shown here. The value is adjustable between
curve 1 and 15, or in position Own curve. The val-
ues for own curve are set in menu 3.6.0. The fac-
tory setting is 9.
Menu 3.2 Offset heatingcurve 2
The chosen offset for the heating curve is shown
here. The value is adjustable between -10 and
+10.
Menu 3.3 Min. flow temp. 2
The set minimum level for the flow temperature to
the heating system is shown here. The calculated
supply temperature never drops below this level
irrespective of the outdoor temperature, curve
slope or offset heating curve. The value is adjust-
able between 10 and 65 °C. The factory setting is
15 °C.
Menu 3.4 Max. flow temp. 2
The set maximum level for the supply tempera-
ture to the heating system is shown here. The
calculated supply temperature never exceeds
this level irrespective of the outdoor temperature,
curve slope or offset heating curve. The value is
adjustable between 10 and 80 °C. The factory
setting is 55 °C.
Menu 3.8 Shunt period time
Here you select the period time, i. e. the time
between corrections for the sub shunt (SV-V2).
The value is adjustable between 10 and 500 sec-
onds. The factory setting is 120 seconds.
Menu 3.9 Shunt intensificat.
Here you select how many seconds the sub shunt
(SV-V2) shall run in relation to the difference
between the calculated flow and the true flow.
For example, a difference of 2 degrees and a set
amplification of 5 gives 10 seconds in control of
the sub shunt. The value is adjustable between 1
and 10. The factory setting is 1.
