8 Configuration
Pump operation mode
When the space heating/cooling operation is OFF, the pump is
always OFF. When space heating/cooling operation is ON, you have
the choice between these operation modes:

▪ 0
operation, regardless of thermo ON or
OFF condition. Remark: Continuous
pump operation requires more energy
than
operation.

[4.5] [F-0D] ▪ 1 Sample: The pump is ON when
there is heating or cooling demand as
the leaving water temperature has not
yet reached the desired temperature
yet. When thermo OFF condition
occurs, the pump runs every 3 minutes
to check the water temperature and
demand

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).
# Code
[4.7] [9-0D]
The maximum values depend on the unit type:

▪ 2 Request: Pump operation based on
request. Example: Using a room
thermostat and thermostat creates

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.
