2.2.1 Method of operation

The storage blocks are heated by the heating
elements located between the storage block
rows. Charging is infinitely adjusted by means
of the charging regulator R1.
The start and end of the charging time are
determined by the electricity supply utility
(EVU) concerned.
Two integrated protective temperature
regulators (N4, N5) and a safety thermal
cut-out (F1) prevent the appliance from

by pressing the button located in the middle
on the safety thermal
The heat which is stored in this way is then
emitted with the help of a blower fan, and
partially also via the surface of the appliance.
In this situation, the room air is sucked in by
the fan (M1) through the air intake grille (6)
and blown through the air ducts of the
storage blocks (9), causing them to be heated.
Before emerging through the air outlet grille
(5), the air, heated in this way, is mixed with
colder room air via two mixed air flaps, in
order to ensure that the emerging air does
not exceed the permitted maximum tempe-
rature. The setting of the mixed air flap, and
therefore of the mixing proportions of the air, is
regulated by means of a bi-metallic regulator.
2.2.2Reducing the connected load
By relocating or removing bridges at the
connection terminals, the connected load,
which is wired at the factory to be 100%, can
be reduced in conjunction with a load degree
reduction device on the charging regulator by
3 output stages (see below).
The dimensions of the lead cross-section and
the fuses are to be selected in accordance with
the maximum possible load of the appliance.
Reducing the degree of charge
Located on the electronic charge regulator
(A1) is the plug-in bridge X17, with which
the degree of charge of the storage part can
be selected in conjunction with the changeable
connection load to four settings (I, II, II or IV).
A charge degree of 100% (Position I) is
preselected at the factory.

If the plug-in bridge is plugged into another
position, this results in a reduced degree of
charge (the disconnection temperature of the
electronic charge regulator will be reduced).
2.2.3 Electronic charge regulator
Fault behaviour
The charge regulator in the appliance is set
at the factory to „Positive fault behaviour
(80% PS)"; i.e. in the event of defective charge
control (such as failure of the control signal),
the appliance will receive a full charge loading.
It is possible to switch over to „Negative
fault behaviour" (no charging of the storage
unit) by replugging the plug-in bridge X16 to
the „80 % PS" position, if the appliance is
connected to a digital charging control unit.
Operation with charge control
The relevant parts of the instructions for
installation and use for the charging control
system are to be followed in this situation.
Control signal
The electronic charging regulator can be
connected to different control signals (ED)
from control units, and can therefore be
integrated into existing older systems. At the
factory, the appliance is set for an AC control
signal (alternating current voltage signal at
the setting at the terminals „A1 + A2") with
80 % ED.
By replugging the plug-in bridge X16, other
ED signals (68/72, 37/40 %) can be selected.
This is necessary if the appliance is being
integrated into an already existing system
which controls the charging with one of the
ED signals mentioned.
