Max. duty

Description

The function makes it possible for a set number of pumps to run
at maximum speed when the function is activated.

Setting range

In this display the number of pumps to run in the operating mode

Max.

10.7.28 User-defined duty (4.3.14.3)

Fig. 55

User-defined duty

Description

In this display it is possible to set a user-defined performance,
typically a performance between min. and max. duty.

The function makes it possible to set a pump performance by
selecting the number of pumps to run and the speed of variable-
speed pumps.

This function primarily selects the variable-speed pumps. If the
number of selected pumps exceeds the number of variable-speed
pumps, mains-operated pumps are started too.

Setting range

•

Number of pumps in operation.

•

Speed as percentage for variable-speed pumps.

Note:

In Hydro MPC booster sets with only variable-speed

pumps the speed can be set between 25 and 100%; in booster
sets with both variable-speed pumps and mains-operated
pumps the speed can be set between 70 and 100%.

Pump curve data

Description

The CU 351 has a number of functions using the pump
performance curves. At delivery the CU 351 contains data
describing these performance curves, but it is also possible to
enter these data. For this purpose use the pump nameplate which
contains data on nominal flow rate, Q
