Fig. 58: Selection of secondary pumps for Multi-Flow Adaptation
Select the partner pump by turning the operating button and press to confirm.
When pressed, the white tick appears on the selected pump.
The secondary pump indicates for its part on the display that it has been selected.
All other secondary pumps are selected in the same way. Then press the Back button to
go back to the "Set control mode" menu.
When secondary pumps are installed in a circuit with a mixer, the mixed volume flow
can be taken into account. For this purpose, select and activate the additional control
function Multi-Flow Adaptation mixer.

To be able to use the function, the temperatures on the feeder pump have to be recor-
ded:
ƒ
in the secondary feed (T1) downstream of the hydraulic shunt
ƒ
in the primary feed (T2) upstream of the hydraulic shunt
For this purpose, connect temperature sensors to the analogue inputs AI3 and AI4.
NOTICE
In order to determine the mixed volume flow, the heat quantity measurement func-
tion with a connected temperature sensor in the secondary feed and secondary re-
turn must always be activated on the secondary pumps with mixer.
