Pump 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).

Description
[4.7]
[9-0D]
Pump 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: 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.
The maximum values depend on the unit type:

Pump outside range
When the pump operation function is disabled the pump will stop if
the outdoor temperature is higher than the value set by the Space
heating off temperature [4‑02] or if the outdoor temperature drops
below the value set by the Space cooling off temperature [F‑01].
When the pump operation is enabled, the pump operation is possible
at all outdoor temperatures.

[F-00]
Pump operation:
▪ 0: Disabled if outdoor temperature is
higher than [4‑02] or lower than [F‑01]
depending
on
heating/cooling
operation mode.
▪ 1:
Possible
at
all
outdoor
temperatures.
Increase around 0°C
Use this setting to compensate for possible heat losses of the
building due to the evaporation of melted ice or snow. (e.g. in cold
region countries).
In heating operation, the desired leaving water temperature is locally
increased around an outdoor temperature of 0°C.This compensation
can be selected when using an absolute or a weather dependent
desired temperature (see illustration below).
