7.1.3 Menu Heating circuit 1 ... 8
Settings for the single heating circuits can be made in this
menu. For the selected heating circuit, for instance, it can be
set here which heating system is installed. In addition it can be
set whether a remote control is available and which control
type is used. There is also the possibility to optimise the
heating curves of the heating circuits.
Signal ext. heat req.
On/Off
An additional on/off temperature controller is connected to the heat source
(e.g. in a building control system).
0-10V
An additional 0-10 V temperature controller is connected to the heat source
(e.g. in a building control system).
Set value ext. heat req.
Flow temperature
The 0-10 V signal that is present at the connection for an external heat
requirement signal is interpreted as a requested flow temperature or heat
output.
