Average timer
The average timer corrects the influence of ambient temperature
variations. The weather-dependent set point calculation is done on
the average outdoor temperature.
The outdoor temperature is averaged over the selected time period.
# Code Description
[A.6.4] [1-0A] Outdoor average timer:
▪ 0: No averaging (default)
▪ 1: 12 hours
▪ 2: 24 hours
▪ 3: 48 hours
▪ 4: 72 hours
INFORMATION
If the power saving function is activated (see [E‑08]), the
average outdoor temperature calculation is only possible in
case the external outdoor temperature sensor is used. See
"5.6 Setting up an external temperature sensor" on
page 15
.
Offset temperature external outdoor ambient sensor
Only applicable in case of an external outdoor ambient sensor is
installed and configured.
You can calibrate the external 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 external outdoor
ambient sensor cannot be installed on the ideal installation location
(see installation).
# Code Description
[A.6.5] [2‑0B] –5°C~5°C, step: 0.5°C (default: 0°C)
Forced defrost
You can manually start a defrost operation.
The decision to execute the manual defrost operation is made by the
outdoor unit and depends on ambient and heat exchanger
conditions. When the outdoor unit accepted the forced defrost
operation, will be displayed on the user interface. If is NOT
displayed within 6 minutes after forced defrost operation was
enabled, the outdoor unit ignored the forced defrost request.
# Code Description
[A.6.6] N/A Do you want to start a defrost operation?
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.
# Code Description
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.
# Code Description
N/A [F‑09] Pump continue operation when flow
abnormality:
▪ 0 (default): Pump will be deactivated.
▪ 1: Pump will be activated when
T
a
<4°C (10 minutes ON – 10 minutes
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).
