Fig. 82

Min. duty

Description

In all systems, apart from MPC-S systems, minimum duty is only
possible for variable-speed pumps. In MPC-S systems, only the
number of pumps running at 100 % speed can be set.

Setting range

• Number of pumps in operation.
• Speed as percentage (25 to 100 %) for variable-speed pumps.

Setting via control panel

• Settings > Secondary functions > Stop function > Min., max.

and user-defined duty > Min. duty.

Select and set:
• Number of pumps in operation, min. duty.
• Speed.

8.7.37 Max. duty (4.3.14.2)

Fig. 83

Max. duty

Description

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

Setting range

You can set the number of pumps to run in the operating mode
"Max.". All pumps run at 100 % speed.

Setting via control panel

• Settings > Secondary functions > Stop function > Min., max.

and user-defined duty > Max. duty.

Select and set: Number of pumps in operation at 100 % speed,
max. duty.

Factory setting
