Configuration Wizard: Backup Heater; Configuration Wizard: Main Zone - Daikin Altherma 3 R W Installation Manual

Booster heater capacity
The capacity of the booster heater must be set for the energy
metering and/or power consumption control feature to work properly.
When measuring the resistance value of the booster heater, you can
set the exact heater capacity and this will lead to more accurate
energy data.
# Code
[9.4.1] [6-02] Booster heater capacity [kW]. Only
applies to domestic hot water tank with
an internal booster heater. The capacity
of the booster heater at nominal voltage.
Range: 0~10 kW

Configuration wizard: Backup heater

The backup heater is adapted to be connected to most common
European electricity grids. If the backup heater is available, the
voltage, configuration and capacity must be set on the user
interface.
The capacities for the different steps of the backup heater must be
set for the energy metering and/or power consumption control
feature to work properly. When measuring the resistance value of
each heater, you can set the exact heater capacity and this will lead
to more accurate energy data.
Backup heater type
The backup heater is adapted to be connected to most common
European electricity grids. The type of backup heater can be viewed
but not changed.
# Code
[9.3.1] [E‑03] ▪ 3: 6V
▪ 4: 9W
Voltage
▪ For a 6V model, this can be set to:
▪ 230V, 1ph
▪ 230V, 3ph
▪ For a 9W model, this is fixed to 400V, 3ph.
# Code
[9.3.2] [5‑0D] ▪ 0: 230V, 1ph
▪ 1: 230V, 3ph
▪ 2: 400V, 3ph
Configuration
The backup heater can be configured in different ways. It can be
chosen to have a 1-step only backup heater or a backup heater with
2 steps. If 2 steps, the capacity of the second step depends on this
setting. It can also be chosen to have a higher capacity of the
second step in emergency.
# Code
[9.3.3] [4‑0A] ▪ 0: Relay 1
▪ 1: Relay 1 / Relay 1+2
▪ 2: Relay 1 / Relay 2
▪ 3: Relay 1 / Relay 2 Emergency Relay
1+2
INFORMATION
Settings [9.3.3] and [9.3.5] are linked. Changing one
setting influences the other. If you change one, check if the
other is still as expected.

INFORMATION
During normal operation, the capacity of the second step of
the backup heater at nominal voltage is equal to
[6‑03]+[6‑04].
INFORMATION
If [4‑0A]=3 and emergency mode is active, the power
usage of the backup heater is maximal and equal to
2×[6‑03]+[6‑04].
Capacity step 1
# Code
[9.3.4] [6‑03] ▪ The capacity of the first step of the
backup heater at nominal voltage.
Additional capacity step 2
# Code
[9.3.5] [6‑04] ▪ The capacity difference between the
second and first step of the backup
heater at nominal voltage. Nominal
value depends on backup heater
configuration.

Configuration wizard: Main zone

The most important settings for the main leaving water zone can be
set here.
Emitter type
Heating up or cooling down the main zone can take longer. This
depends on:
▪ The water volume of the system
▪ The heater emitter type of the main zone
The setting Emitter type can compensate for a slow or a quick
heating/cooling system during the heat up/cool down cycle. In room
thermostat control, Emitter
modulation of the desired leaving water temperature, and the
possibility for usage of the automatic cooling/heating changeover
based on the indoor ambient temperature.
It is important to set Emitter type correctly and in accordance with
your system layout. The target delta T for the main zone depends on
it.
# Code
▪ 0: Underfloor heating
[2.7] [2‑0C]
▪ 1: Fancoil unit
▪ 2: Radiator
The setting of the emitter type has an influence on the space heating
setpoint range and the target delta T in heating as follows:
