The value can be set between curves 0 and 20. The factory
setting is 9.
Menu 2.2 Heating curve offset
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 2.3 Min supply temp.
The desired minimum level for the supply temperature for
the heating system is selected here.
The calculated flow temperature never drops below the set
level irrespective of the outdoor temperature, curve slope
or offset heating curve.
The value can be set between 10 and 65 °C. The factory
setting is 15 °C.
Menu 2.4 Max supply temp.
The desired maximum level for the supply temperature for
the heating system is selected here.
The calculated flow temperature never exceeds the set level
irrespective of the outdoor temperature, curve slope or
offset heating curve.
The value can be set between 10 and 80 °C. The factory
setting is 55 °C.
Menu 2.5 External adjustment
Connecting an external contact, see “Electrical connec-
tions - External contacts”, for example, a room thermostat
or a timer allows you to temporarily or periodically raise
or lower the supply temperature and with that the room
temperature. When the external contact is made, the heat-
ing curve offset is changed by the number of steps shown
here.
The value can be set between -10 and +10. The factory
setting is 0.
Menu 2.6.0 Own heat curve
Here you can select your own heat 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 2.1 must be set to 0 to
activate this function.
Menu 2.6.1 Supply temp.at +20ºC
The supply temperature at an outside temperature of +20
is selected here.
The value can be set between 0 and 80 °C. The factory set-
ting is 15 °C.
Menu 2.6.2 Supply temp.at -20ºC
The supply temperature at an outside temperature of -20 is
selected here.
The value can be set between 0 and 80 °C. The factory set-
ting is 35 °C.
Menu 2.6.3 Buckling temperature
Here you select at what outside temperature the break
point shall occur.
The value can be set between -15 and +15 °C. The factory
setting is 0 °C.
Menu 2.6.4 Supply t. at buckl.
You set the required flow temperature for the break point
here.
The value can be set between curve 0 and 80 °C. The fac-
tory setting is 20 °C.
Menu 2.6.5 Return
Return to menu 2.6.
Menu 2.7 Return temperature
The current actual return line temperature from the heat-
ing system is shown here.
Menu 2.8 Degree-minutes
Current value for number of degree-minutes. For example,
this value can be changed to accelerate the start of heating
production.
The value can be changed from -700 and downwards.
Menu 2.9 Return
