5.9.2 Summer/winter filter constant
The filter constant of 250 is applicable for average buildings. A
filter constant of 1 is close switching according to actual outdoor
temperature meaning low filtering (very "light" building).
A filter constant of 300 is then to be chosen if a big filtering is
needed (very heavy building).
For heating circuits where the heat cut-out is demanded according
to the same outdoor temperature for the whole year, but different
filtering is wanted, different dates have to be set in the "Heat
cut-out" menu enabling a selection of a filter constant different
from the factory setting.
These different values have to be set in both the "Summer" and
"Winter" menu.
