# Code Description
[A.6.3.1] [4-08] Mode:
▪ 0 (No limitation)(default): Disabled.
▪ 1 (Continuous): Enabled: You can
set one power limitation value (in A
or kW) to which the system power
consumption will be limited for all the
time.
▪ 2 (Digital inputs): Enabled: You can
set up to four different power
limitation values (in A or kW) to
which the system power
consumption will be limited when the
corresponding digital input asks.
[A.6.3.2] [4-09] Type:
▪ 0 (Current): The limitation values are
set in A.
▪ 1 (Power)(default): The limitation
values are set in kW.

time power limitation mode.
0A~50A, step: 1A (default: 50A)
[A.6.3.4] [5-09] Value: Only applicable in case of full
time power limitation mode.
0kW~20kW, step: 0.5kW (default:
20kW)

[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 RHBH/
X04+08 and RHVH/X04+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 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
"5.7 Setting up an external temperature sensor" on
page22.
