Quick guide - menu settings sub shunt
Menu 9.1.4 Sub shunt [S]
Here the sub shunt is set either On or Off. The factory
setting is Off.
Menu 3.1 Curve slope 2 [N]
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 values for own curve are set
in menu 3.6.0. The factory setting is 9.
Menu 3.2 Offset heatingcurve 2 [N]
The chosen offset for the heating curve is shown here.
The value is adjustable between -10 and +10. The factory
setting is 0.
If the RCU is connected, the set offset is shown via RCU
between brackets. The actual offset then becomes the
total of the set offset and RCU offset.
Menu 3.3 Min. flow temp. 2 [U]
The set minimum level for the flow temperature to the
heating system is shown here. The calculated supply tem-
perature never drops below this level irrespective of the
outdoor temperature, curve slope or offset heating curve.
The value is adjustable between 10 and 65 °C.
The factory setting is 15 °C.
Menu 3.4 Max. flow temp. 2 [U]
The set maximum level for the supply temperature 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 [U]
Here you select the period time, i. e. the time between
corrections for the sub shunt (SV-V2). The value is adjust-
able between 10 and 500 seconds. The factory setting is
120 seconds.
Menu 3.9 Shunt intensificat. [U]
Here you select how many seconds the sub shunt (SV-V2)
shall run in relation to the difference between the calcu-
lated 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.
