Description
0
No limitation
1~4
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

7:
70% pump speed during sampling
▪
8:
60% pump speed during sampling
