Flow temperature system 2
Menu 3.4 Flow temp2./MAX
The set maximum level for the supply temperature to
the heating system is shown here. The value is
adjustable between 10 and 80 °C.
The calculated flow temperature never exceeds
the set level irrespective of the outdoor temperature,
curve slope or heating curve offset.
Menu 3.1 Curve coefficient 2
The selected curve slope (heating curve) is shown
here. The “Own curve” function is activated at value 0,
see menu 3.6.0. The value can be set between curve
0 and 15.
Menu 3.2 Offs.heating curve 2
The selected heating curve offset is shown here. The
value is adjustable between -10 and +10. NOTE! The
value is changed using the “Heating curve offset”
knob.
Menu 3.3 Flow temp2./MIN
The set minimum level for the supply temperature to
the heating system is shown here. The value is
adjustable between 10 and 80 °C.
The calculated flow temperature never drops below
the set level irrespective of the outdoor temperature,
curve slope or heating curve offset.

Menu 3.5 External adjustment 2
Connecting an external contact, see “Electrical con-
nections - External contacts”, for example, a room
thermostat (accessory) or a timer allows you to tem-
porarily or periodically raise or lower the room temper-
ature. When the external contact is made, the heating
curve offset is changed by the number of steps shown
here. The value is adjustable between -10 and +10.
Menu 3.6.0 Own curve def. 2
Here you can select your own curve definition. This is
an individual linear curve with one break point. You
select a break point and the associated temperatures.
NOTE! The “Curve slope” in menu 3.1 must be set to
0 to activate this function.
Menu 3.6.1 Flow temp.at +20°C
The flow temperature at an outside temperature of
+20°C is chosen here. The value is adjustable
between 0 and 60°C.
Menu 3.6.2 Flow temp.at -20°C
The flow temperature at an outside temperature of
-20 °C is chosen here. The value is adjustable
between 0 and 60°C.
Menu 3.6.3 Set temperature 2
Here you select at what outside temperature the break
point shall occur. The value is adjustable between -15
and +15 °C.
