21. Hardware reset
A hardware reset can be carried out in the event that the Troll
Comfort DuoFern fails to react to commands. To do so, pull the
control unit [ 1 ] our of the installation housing [ 3 ].
The centre section on rear of the control unit [ 1 ] contains two
contacts which should be carefully bridged for a few seconds,
for example, with the help of a at-head screwdriver.
The control unit [ 1 ] can be replaced into the installation hous-
ing [ 3 ] 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.
