9.1 Display and control elements of devices with
TEC program control
9.2 Accumulator function
The accumulator function ensures that cold energy is stored automatically (up to
8 hours) if enough electrical power is available, for example when supplied by a
mains adapter.
Stored cooling power is discharged
• automatically when the switch-off voltage is reached (see the table on page 18)
• or manually by pressing the discharge button (fig. 1 A2 or fig. 2 4, page 3).

Explanation
1 Green LED: Indicates that the compressor is working.
2 Yellow LED: indicates that the external power supply is present (voltage is
higher than 13.5 V or 27.0 V).
The LED flashes if the external power supply is too low (voltage ≤ 10.7 V or
21.7 V. Version E: ≤ 10.7 V or 22.0 V).
3 Red LED: indicates that the accumulator is being discharged because
• the discharge button has been pressed
• Low voltage shutdown (voltage ≤ 10.7 V or 21.4 V. Version E: ≤ 10.7 V or
22.0 V).
4 Accumulator discharge button: interrupts compressor operation until
• the stored cold energy is exhausted
• The external supply voltage level is restored after low voltage.
5 Temperature selector: allows the temperature in the cooling area to be set
as required
Min. (left limit) = warmest setting
Max. (right limit) = coldest setting
6 Main switch: for switching the cooling device on and off.
Position 0 = OFF
Position – = ON
