NSB : Night Setback
This option allows you to set the value by which the tem-
perature should be reduced when NSB is activated . NSB
is activated either by the event schedule or with a signal
from an external timer connected to terminal S .
When the NSB signal is active, a half-moon icon is shown
in the display together with the lowered setpoint
temperature .
The function is factory set to 5°C but can be set to values
between 2-8° in increments of 0 .5°C .
If the Application is set to
C
and ”Night setback” is
selected, the night setback is set in relative values . The
setpoint specifies (in percent) the time that the unit is to
remain active in a PWM cycle, which is usually 20 min .
Setback degree is specified as a percentage of the
setpoint . The setpoint multiplied by the setback degree
gives the activation degree .
Example: If the setpoint is set to 60% and night setback
is set to 25%, the activation degree will be (0 .60 x 0 .25 =
0 .15) = 15% .
How to execute it:
• Access the menu .
• Scroll through the menu to NSB .
• Press the centre button to enter the Night setback
setting .
• Use the upper or lower button to adjust the value by
which you want to decrease the temperature when NSB
is activated .
• Confirm your choice with the centre button .
