7.10 Forwarding the outdoor temperature
The outdoor temperature can be passed on over the analog output AA (0 to 10 V, terminal 11)
(0 to 10 V corresponding with –40 to 50 °C outdoor temperature).

7.11 Flow rate/capacity limitation over a pulse input
Flow rate/capacity limitation can be implemented based on a pulse signal.
There are three different operating situations:
4
A system with simultaneous room heating and DHW heating requires maximum energy.
4
A system with a fully charged storage tank which performs only room heating requires less
energy.
4
A system which suspends room heating during DHW heating requires less energy.
As a result, three different maximum limit values can be specified:
4
Max. limit value to determine the absolute upper limit
4
Max. limit value for heating for exclusive operation of the room heating
4
Max. limit value for DHW for exclusive operation of the DHW heating
In all systems without DHW heating, only the
Max. limit value for the flow rate or capacity can
be set.
