30. Performing a hardware reset
i
A hardware reset can be performed in the event that the Troll Comfort
DuoFern no longer react to commands.
1.
To do so, pull the operating unit out of the installation housing.
2.
The centre section on the rear
of the operating unit contains
an opening with two contacts
that must be carefully bridged
for a few seconds, for example,
with the help of a flat-head
screwdriver.
3.
The operating unit can be returned to the installation housing as soon
as the screwdriver has been removed from the contacts.
The time and date will be lost during a hardware reset. All other settings
are retained.
