Requesting an external demand

The flow temperature set points can be passed on over the LON network in complex heating sys- tems. The external flow set point is compared with the controller’s own flow set point. The higher of the two flow set points is passed on.

Note!

In systems Anl 6 and 9, the setting Co5 -> Fb00 = OFF must be configured for passing on the flow temperature set point. In all other systems, the setting Co5 -> Fb00 = ON must be configured.

Processing an external demand

The master controller receives the demand of connected controllers over the LON network and makes the required energy available for all the control circuits. The secondary flow sensor in- stalled directly downstream of the heat exchanger serves as the sensor for the primary valve. The Boost parameter improves the control performance of the connected heating circuit valves and compensates for any loss in capacity.

If an internal heating circuit has the highest set point, the primary valve regulates the tempera- ture at the flow collector to the set point of the heating circuit plus Boost.

The set point in the heating circuit is regulated by the mixing valve of the heating circuit. In InF5 level, the set point of the primary valve appears on the display in this case.

Note! In systems Anl 6 and 9, the external demand is only sent and not processed.
