NOTICE
An overpressure bypass valve can be integrated in the
system. Keep in mind that this valve might not be shown
on the illustrations.
Glycol Filled system
This setting gives the installer the possibility to indicate whether the
system is filled with glycol or water. This is important in case glycol is
used to protect the water circuit against freezing. If NOT set
correctly, the liquid in the piping can freeze.
# Code Description
N/A [E-0D] Glycol Filled system : Is the system
filled with glycol?
▪ 0: No
▪ 1: Yes
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 Description
[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
7.2.4 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 Description
[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 Description
[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 Description
[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].
INFORMATION
Only for systems with integrated domestic hot water tank: If
the storage temperature setpoint is higher than 50°C,
Daikin recommends NOT to disable the backup heater
second step because it will have a big impact on the
required time for the unit to heat up the domestic hot water
tank.
Capacity step 1
# Code Description
[9.3.4] [6‑03] ▪ The capacity of the first step of the
backup heater at nominal voltage.
Additional capacity step 2
# Code Description
[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.
7.2.5 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 type
influences the maximum
modulation of the desired leaving water temperature, and the
possibility for usage of the automatic cooling/heating changeover
based on the indoor ambient temperature.
