Pump speed limitation
Pump speed limitation [9‑0D] 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).
# Code Description
N/A [9‑0D] Pump speed limitation
▪ 0: No limitation.
▪ 1~4: General limitation. There is limitation in all
conditions. The required delta T control and
comfort are
NOT guaranteed.
▪ 5~8 (default: 6): Limitation when no actuators.
When there is no heating/cooling output, the
pump speed limitation is applicable. When
there is heating/cooling 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.
The maximum values depend on the unit type:
