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).

Outdoor temperature passed on over AA	OFF	Co5 -> Fb15 = ON

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:

A system with simultaneous room heating and DHW heating requires maximum energy. A system with a fully charged storage tank which performs only room heating requires less

energy.

A system which suspends room heating during DHW heating requires less energy.

As a result, three different maximum limit values can be specified: Max. limit value to determine the absolute upper limit

Max. limit value for heating for exclusive operation of the room heating 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.
