Daikin Altherma – Low temperature split
4P556075-1 – 2019.02
# Code Description
[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
heating or cooling if
necessary. Remark: Sample is ONLY
available in leaving water temperature
control.

request. Example: Using a room
thermostat and thermostat creates

Unit type
In this part of the menu it can be read out which type of unit is used:
# Code Description
[4.6] [E‑02] Unit type:
▪ 0 Reversible (only with EKHVCONV2
installed)
▪ 1 Heating only
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.
[4.8] [9-0E] Pump 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: 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.
