Commissioning
Power failure and thus the switch to the internal battery is indicated by an
alarm sound, as well as by the message “Battery Operation” (see Fig. 10). In
addition, the power LED will glow red and the alarm button will glow orange.
To switch the alarm off, press the alarm button. The alarm sound is switched
off, the message “Battery Operation” is hidden, and the power LED goes out.
When the power supply returns, the device is supplied with power from
the mains supply and the internal battery is charged and the power LED
is lit green again.
OPERATION WITH EXTERNAL BATTERY
Only the HOFFRICHTER AKKUPACK uni BASE may be used for the
external power supply. Before initial commissioning, you must read
the user’s manual for AKKUPACK uni BASE.
The AKKUPACK uni BASE enables the device to be operated indepen-
dently of the mains power supply. The battery pack is optionally available
as an accessory.
To supply the battery pack with power, use the power cable and the power
supply unit of the ventilator. If the battery pack is connected to the venti-
lator, the power LED lights green.
At full capacity and factory settings, the AKKUPACK uni BASE enables
TRENDvent to operate for up to 10 hours. Using AKKUPACK uni BASE
together with AKKUPACK uni PLUS doubles operation time to up to 20 hours.
For further information on connecting and handling the device, please refer
to the respective user’s manual.
