Nibe SPLIT HBS 12 Installation And Maintenance Instructions Manual page 59

Menu 2.2.4 [N] Min supply cooling
The set minimum level for the supply temperature to the
climate system during cooling is shown here.
The calculated flow temperature never drops below the
set level irrespective of the outdoor temperature, curve
slope or offset heating curve.
Setting range: 7 – 25 °C
Default value: 18 °C
NOTE
For HBS 10-12 cooling operation is permitted down
to +18°C in the supply temperature to prevent con-
densation in the product.
HBS 11-12 is insulated to prevent condensation for
cooling operation down to +7°C in the supply tem-
perature.
Menu 2.2.5 [N] Circ-pump speed cool
The speed of the heating medium pump during house
cooling is selected here.
Setting range: 1 – 100
Default value: 60
Menu 2.2.6 [N] Return
Return to menu 2.2.0.
Menu 2.3 [U] Max supply temp.
The set maximum level for the supply temperature to the
climate system is shown here.
The calculated flow temperature never exceeds the set
level irrespective of the outdoor temperature, curve slope
or offset heating curve.
Setting range: 25 – 65 °C
Default value: 55 °C
Menu 2.4 [U] External adjustment
Connecting an external contact, for example, a room
thermostat (accessory) or a timer allows you to temporarily
or periodically raise or lower the room temperature. When
the external contact is closed, the heating curve offset is
changed by the number of steps shown here.
If room control is active there is a degree change to the
set room temperature.
Setting range: -10 – 10
Default value: 0
Menu 2.5 [U] Supply/Return temp.
The current actual flow and return line temperatures are
shown here.
Menu 2.6 [U] Degree minutes
Current value for number of degree-minutes. For example,
this value can be changed to accelerate the start of heating
production or cooling.
Setting range: -32000 – 32000
Menu 2.7 [N] Return
Return to menu 2.0.
* Limited by menu 3.4 Max supply temp. 2.
3.0 [N] Supply temp. 2
Menu 3.1 [N] Offset heating/Tot 2
The selected heating curve offset 2 is selected here.
The total offset of heat curve 2 is also shown here. It in-
cludes schedule, outer compensation and any room con-
trol.
Setting range: -10 – 10
Default value: -1
Menu 3.2 [N] Heating curve 2
The selected curve slope (heating curve) is shown here. At
value 0, the function "Own heat curve 2" is activated, see
menu 3.6.0.
Setting range: 0 – 20
Default value: 6
Menu 3.3 [U] Min supply temp. 2
The set minimum level for the supply temperature for cli-
mate system 2 is shown here.
The calculated flow temperature never drops below the
set level irrespective of the outdoor temperature, curve
slope or offset heating curve.
Setting range: 10 – 65 °C
Default value: 15 °C
Menu 3.4 [U] Max supply temp. 2
The set maximum level for the supply temperature for cli-
mate system 2 is shown here.
The calculated flow temperature never exceeds the set
level irrespective of the outdoor temperature, curve slope
or offset heating curve.
Setting range: 10 – 65 °C
Default value: 45 °C
Menu 3.5 [U] External adjust. 2
Connecting an external contact, for example, a room
thermostat (accessory) or a timer allows you to temporarily
or periodically raise or lower the room temperature. When
the external contact is closed, the heating curve offset is
changed by the number of steps shown here.
If room control is active there is a degree change to the
set room temperature.
Setting range: -10 – 10
Default value: 0
Menu 3.6.0 [U] Own heating curve 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 3.2 must be set to 0 to
