Value
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
