Pump continue operation when flow
abnormality:
▪ 0 (default): Pump will be deactivated.
▪ 1: Pump will be activated when

OFF)
Pump speed limitation
Pump speed limitation main zone [9‑0E] and pump speed limitation
additional zone [9‑0D] define 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).

Pump speed limitation
main 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 (default: 6): 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.
