Extended

Time in ext. 
running
0 min
Set the time for extended 
running. Digital inputs can be 
used to force the unit to start 
or increase to Normal running 
although the timer says the 
running mode should be Off or 
Reduced
If the running time is set to 0 
the unit only runs as long as the 
digital input is closed.
The time that extended running 
is active is monitored in “Time in 
ext. Running”,
It’s also possible to set a time 
here in order to shorten the 
initial set period.
→ Holidays Holidays
(mm:dd)
1:01-01 – 01-02
2:09-04 – 09-10
3:01-05 – 01-05
Set up to 24 separate holiday 
periods for a full year.
A holiday period can be any 
number of consecutive days 
from one and upwards.
The dates are in the format:
MM:DD
When the current date falls 
within a holiday period, the 
scheduler will use the settings 
for the weekday “Holiday”.
→ Manual/Auto
In this menu the running mode 
of all the congured output 
signals and a number of control 
functions can be manually 
controlled.
The supply air controller’s 
output signal can be manually 
set (Manual/Auto) to any value 
between 0 and 100%. The 
temperature output signals will 
change accordingly if they are 
in Auto mode. It is also possible 
to manually control each of 
the temperature output signals 
individually.
Since leaving any of the 
outputs in manual control will 
disrupt the normal control, 
an alarm will be generated as 
soon as any output is set to a 
manual mode.
