Value 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

▪ 6: 80% pump speed during sampling

▪ 7: 70% pump speed during sampling

▪ 8: 60% pump speed during sampling
