Pump limitation
The pump speed limitation defines the maximum pump speed. In normal
conditions, the default setting should NOT be modified. The pump speed limitation
will be overruled when the flow rate is in the range of the minimum flow (error
7H).
In most cases, instead of using [9-0D]/[9-0E], you can prevent flow noises by
performing hydraulic balancing.

General limitation. There is limitation in all conditions. The
required delta T control and comfort are NOT guaranteed.
▪
1:
90% pump speed
▪
2:
80% pump speed
▪
3:
70% pump speed
▪
4:
60% pump speed
5~8
Limitation when no actuators. When there is no heating output,
the pump speed limitation is applicable. When there is heating
output, the pump speed is only determined by delta T in
relation to the required capacity. With this limitation range,
delta T is possible and the comfort is guaranteed.
During sampling operation the pump runs for a short time to
measure the water temperatures, which indicate if operation is
required or not.
▪
5:
90% pump speed during sampling
▪
6:
80% pump speed during sampling
▪
7:
70% pump speed during sampling
▪
8:
60% pump speed during sampling
The maximum values depend on the unit type:
