*This compensation only takes place when the
attic temperature is warmer than the “Attic start

the room temperature is warm enough and
reaches the
“Room Stop T°”
value. At the end
of the compensation, the minimum ventilation
“On Time”
goes back to its regular value, and
the sidewall vent starts being used jointly
with the attic vent.
If the room temperature is higher than the cut-
off point of the attic compensation and then
starts decreasing, the
“On Time”
becomes
fully compensated when the room tempera-
ture falls to the attic compensation’s cut-off
point
(“Attic stop comp. at”)
. The
“On Time”
then
starts decreasing gradually, in a linear fash-
ion, as the room temperature falls. The
“On
Time”
finally stops being compensated when
the room temperature reaches the
“Attic start
comp at”
value.

Set the following parameters: 2.
Attic start comp. at — Select the attic tem-
perature over which the attic compensation
can be used. This parameter also represents
the room temperature over which the
“On
Time” portion of the minimum ventilation
timer starts decreasing in a linear fashion as
the temperature rises (see graph).
Attic stop comp. at — Select the room tem-
perature at which the attic compensation
ends. Note that this temperature must be
higher than the compensation’s start tem-
perature and lower than the room temperature
at which the 1
st
fan stage starts.
