[A.6.3.7] [4-01] Power consumption control
DISABLED [4
‑
08]=0
▪ 0 (None)(default): Backup heater and
booster heater can operate
simultaneously.
▪ 1 (BSH): The booster heater is
prioritized.
▪ 2 (BUH): The backup heater is
prioritized.
Power consumption control
ENABLED [4
‑
08]=1 or 2
▪ 0 (None)(default): Depending on the
power limitation level, the booster
heater will be limited first, before the
backup heater is limited.
▪ 1 (BSH): Depending on the power
limitation level, the backup heater will
be limited first, before the booster
heater is limited.
▪ 2 (BUH): Depending on the power
limitation level, the booster heater
will be limited first, before the backup
heater is limited.
Note: In case of power consumption control is DISABLED (for all
models) the setting [4
‑
01] defines whether backup heater and
booster heater can operate simultaneously, or if the booster heater/
backup heater has priority over the backup heater/booster heater.
In case of power consumption control is ENABLED (only for EHBH/
X04+08 and EHVH/X04+08), the setting [4
‑
01] defines the priority of
the electrical heaters depending on applicable limitation.
# Code Description
[A.6.3.7] [4-01] ▪ 0 (None)(default): No heater is
prioritized. If the power consumption
control is enabled, the booster heater
will be limited first.
▪ 1 (BSH): The booster heater is
prioritized. If the power consumption
control is enabled, the backup heater
(step 1 and/or step 2) will be limited

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:
▪ No averaging (default)
▪ 12 hours
▪ 24 hours
▪ 48 hours
▪ 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
"5.7 Setting up an external temperature sensor" on
page 20.
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] −5~5°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?
▪ OK
▪ Cancel
Pump operation
The pump operation field setting apply to the pump operation logic
only when [F-0D]=1.
When the pump operation function is disabled the pump will stop if
the outdoor temperature is higher than the value set by [4-02] or if
the outdoor temperature drops below the value set by [F-01]. When
the pump operation is enabled, the pump operation is possible at all
outdoor temperatures.
# Code Description
N/A [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.
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 disactivated 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: Pump will be desactivated.
▪ 1: Pump will be activated when
T
a
<4°C (10 minutes ON – 10 minutes
OFF)
