Pump limitation
The pump speed limitation for the main zone [9‑0E] and additional zone [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
[4.7] [9-0D] Pump limitation Additional zone :
▪ 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: 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.
