# Code
[A.6.3.7] [4-01] Power consumption control
DISABLED [4‑08]=0
▪ 0 (None)(default): Backup heater and
booster
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
EHVH04+08 ), the setting [4‑01] defines the priority of the electrical
heaters depending on applicable limitation.
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
[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 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
[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
