Additional functions

Sleep-Modus
If the control unit has been working by battery for more than 2 hours, it goes into the so-called "Sleep mode". This
means that the operating valve flap is closed automatically. During sleep mode (flap closed), an optical and acoustic
alarm is given every 20 seconds until the battery is discharged. At the same time, the alarm is displayed via the optional
potential-free contact. In sleep mode, the control unit is in a "resting position". All the displays are switched off. The fault
message via the potential-free contact remains, however. Once mains voltage is available again, the control unit returns
to normal operation immediately. This function prevents the battery from being discharged completely and then no
longer being able to function in the event of a power failure. This is particularly important during the construction phase,
for example, when the control unit is installed but not yet continuously supplied with mains current. In this case, the FKA
is ready for operation thanks to battery operation, but the battery is not discharged complete.
