installed.
Description
The CU 352 does not have analog outputs as standard, but the
system can be fitted with an IO 351B module with three analog
outputs.
Setting via control panel

8.7.35 Min., max. and user-defined duty (4.3.14)

Fig. 81 Min., max. and user-defined duty
Description
This function makes it possible to let the pumps run in open loop
at a set performance.
Setting range
The CU 352 makes it possible to change between three operating
modes:
1. Min. duty (4.3.14.1).
2. Max. duty (4.3.14.2).
3. User-defined duty (4.3.14.3).
For each of these operating modes, the number of
operating pumps and the pump performance (speed)
Note
can be set.
