The overheating protection that requires manual
resetting can be reset by pressing a button located
inside the ventilation unit. The location of the button
is marked in the illustration below. When you press
the reset buttons and feel a click, the overtempera-
ture protection (thermal overload cut out) has then
been reset.
Temperature sensors
If a sensor fault is detected, the ventilation unit enters
restricted mode to prevent damage to the ventila-
tion unit. The functions related to the current sen-
sor in question are deactivated and the ventilation
unit works as well as possible. The ventilation unit's
function returns to normal once the fault has been
corrected.
