[A.6.4]
[1-0A]
Outdoor average timer:
▪ 0: No averaging (default)
▪ 1: 12 hours
▪ 2: 24 hours
▪ 3: 48 hours
▪ 4: 72 hours
Offset temperature remote outdoor ambient sensor
You can calibrate the remote outdoor ambient temperature sensor. It
is possible to give an offset to the thermistor value. The setting can
be used to compensate for situations where the remote outdoor
ambient sensor cannot be installed on the ideal installation location
(see installation).

Description
[A.6.5]
[2‑0B]
–5°C~5°C, step: 0.5°C (default: 0°C)
The weather-dependent leaving water temperature setpoint is
calculated based on the outdoor ambient temperature + [2‑0B].
However, the user interface will ONLY display the outdoor ambient
temperature (without the addition of [2‑0B]).
Pump operation
When the pump operation function is disabled the pump will stop if
the outdoor temperature is higher than the value set by [4‑02]. When
the pump operation is enabled, the pump operation is possible at all
outdoor temperatures.

N/A
[F‑00]
Pump operation:
▪ 0 (default): Disabled if outdoor
temperature is higher than [4‑02].
▪ 1:
Possible
at
all
outdoor
temperatures.
Pump operation during flow abnormality [F‑09] defines whether the
pump stops at flow abnormality or allow to continue operation when
flow abnormality occurs. This functionality is only valid in specific
conditions where it is preferable to keep the pump active when
T
a
<4°C (pump will be activated for 10 minutes and deactivated after
10 minutes). Daikin shall NOT be held liable for any damage
resulting this functionality.

N/A
[F‑09]
Pump continue operation when flow
abnormality:
▪ 0: Pump will be deactivated.
▪ 1 (default): Pump will be activated
when T
a
<4°C (10 minutes ON – 10
minutes OFF)
Pump speed 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
Description
N/A
[9‑0D]
Pump speed 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 (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.
The maximum values depend on the unit type:
