2.2.1 Function Principle
The storage blocks are heated up by the heating elements between the rows of storage blocks.
Charging is set continuously with the charging control unit (selector knob fig. 17)
Start and duration of the charging time are determined by the responsible electricity supply
company.
Two built-in safety temperature regulators (19, 20) and a safety temperature limiter (21) prevent
overheating of the unit. Whilst the safety temperature regulators switch on again automatically,
the safety temperature limiter must be switched back on by the technician by pressing in the knob
in the middle of the limiter after eliminating the cause of the error.
The heat stored in this way is then discharged with the aid of a fan, also partly through the heater
surface. In this case, the room air is sucked in through the air inlet grille (6) by the fan (18) and
blown through the air ducts of the storage blocks (9) which heats them up.
Before being output through the air outlet grille (5) the hot air generated in this way is mixed via
two mixing air flaps with colder room air so that the emitted air does not exceed the maximum
permissible temperature. The position of the mixing air flap and thus the
mixing ratio of the air is controlled by a bi-metal controller.
