7.12 Outdoor temperature output
If the analog output AA is not required for air volume control or the request for the externally
required signal and Anl 8 or Anl 9 is not selected, the outdoor temperature is issued as a 0
to 10 V signal at the analog output AA. The outdoor temperature can be measured either
with a temperature sensor at F3 or alternatively using an analog input. The measuring range
is permanently allocated:
0 to 10 V = –40 to +50 °C.
The outdoor temperature can be passed on to other controllers using this function.

fected by the locking function. The locking function is inactivated by switching it off.
