8.2

Factory settings

The appliance connection is wired to the maximum output (100%).
If jumpers at the terminals are moved or removed, the connected
load can be matched.
8.3

Design operation

The storage blocks are heated via the heating elements between
the rows of storage blocks. The charge can be infinitely adjusted
with the charge controller. The start and duration of the charge
time are set by the local power supply utility.
Two integral protective thermostats and a high limit safety
cut-out prevent the appliance overheating. The protective
thermostats switch back on automatically, but the high limit safety
cut-out must be switched back on after the cause of the fault has

The stored heat is transferred via a fan, and partially also via the
appliance surface. For this, the room air is drawn in by the fan
through the air inlet grille, and released through the air ducts in
the storage blocks, which heats it. Before the hot air produced in
this way is released via the air outlet grille, it is mixed with cooler
room air via two mixing air dampers, so the expelled air does not
exceed the highest permissible temperature. The position of the
mixing air damper, and thus the mixing ratio of the air, is regulated
via a bi-metal controller.
