Setting range: 1 – 24 h

Here, you select the return time for the temporary speed
change (speed 1 – speed 4) of the ventilation in menu

MENU 1.2.6 - FILTER CLEANING INTERVAL

Months between filter cleaning

Setting range: 1 – 24 months

The filters in ERS S10 are of a type that should not be
cleaned, they have to be replaced instead. These must
be replaced regularly; how often depends e.g. on the
amount of dust in the ventilation air. Test to find out
what is most appropriate for your installation.

Set the interval for the reminder in this menu.

The menu shows the time remaining until the next re-
minder, and you can also reset active reminders.

Cooling recovery:

When there is no heating demand,

ventilation recovery is stopped to prevent the house
from being heated further. When it is warm indoors and
even warmer outdoors, ERS S10 can be used to prevent
the house from heating up more than necessary. During
cooling recovery, the cooler air from the house is used
to cool the incoming air.

"Cooling recovery" is started when the exhaust air tem-
perature is a certain number of degrees below the out-
door temperature and it is warm outside.

St temp sup air cooled by exh air:

Here, you set the

outdoor temperature at which cooling recovery will start.

Caution

"St temp sup air cooled by exh air" cannot be
lower than "Stop heating" in menu 7.1.10.2 –
"Auto mode setting".

Min diff outd and exhaust air:

Here, you set the temper-

ature difference between outdoor air and exhaust air
that is required in order for cooling recovery to start.
