Menu system
MENU 7.2.1 - ADD/REMOVE ACCESSORIES
Here, you state which accessories are installed for the
compatible product.
To automatically identify connected accessories, select
"Search for installed accessories". It is also possible to
select accessories from the list manually.
MENU 1.2.1 - FAN SPEED
Alternative: normal and speed 1-4
The ventilation in the accommodation can be temporarily
increased or reduced here.
When you have selected a new speed a clock starts a
count down. When the time has counted down the
ventilation speed returns to the normal setting.
If necessary, the different return times can be changed
in menu 1.2.5.
The fan speed is shown in brackets (in percent) after
each speed alternative.
MENU 1.2.2 - NIGHT COOLING
Start temperature, exhaust air
Setting range: 20 – 30 °C
Lowest diff., outdoor/exhaust air
Setting range: 3 – 10 °C
Activate night cooling here.
When the temperature in the house is high and the
outdoor temperature is lower, a cooling effect can be
obtained by forcing the ventilation.
If the temperature difference is greater than the set
value for “Min diff outdoor and exhaust air”, and the
exhaust air temperature is higher than the set value for
“Start temperature exhaust air”, the ventilation operates
at speed 4 until one of these conditions is no longer
valid.
Caution
Night cooling is only activated when heating is
not permitted.
MENU 1.2.5 - FAN RETURN TIME
Select the return time here for the temporary speed
change (speed 1-4) of the ventilation in menu 1.2.1.
Return time is the time it takes before ventilation speed
returns to normal.
MENU 1.2.6 - FILTER CLEANING INTERVAL
Cleaning interval
Setting range: 1 – 24 months
Clean the filter in S135 regularly; how often depends on
the amount of dust in the ventilation air.
Set the interval for the reminder to clean the filter in this
menu.
The menu shows the time remaining until the next re-
minder, and you can also reset active reminders.
MENU 7.2.13 - EXHAUST AIR MODULE (S135)
charge pump speed
Setting range: 1 – 100 %

cooling” to be activated.
