5 Configuration
INFORMATION
Only for systems with integrated domestic hot water tank: If
the storage temperature set point 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
[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
Depending on the system water volume and the heater emitter type
of the main zone, the heat up or cool down of the main zone can
take longer. This setting can compensate for a slow or a quick
heating/cooling system during the heat up/cool down cycle. The
target delta T for the main zone will depend on this setting.
In room thermostat control, this setting will influence 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.
Therefore it is important to set this correctly and in accordance with
your system layout.
# Code
[2.7] [2‑0C] ▪ 0: Underfloor heating
▪ 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:
Description Space heating
setpoint range
0: Underfloor heating Maximum 55°C
1: Fancoil unit Maximum 55°C
2: Radiator Maximum 65°C
NOTICE
For radiators, the average emitter temperature will be
lower compared to underfloor heating, due to the fixed
delta T of 8°C. To compensate, you can:
▪ Increase the weather
temperatures [2.5].
▪ Enable leaving water temperature modulation and
increase the maximum modulation [2.C].
Control
For the control of the unit there are 3 possibilities:

Control
Leaving water Unit operation is decided based on the leaving
water temperature regardless the actual room
temperature and/or heating or cooling demand
of the room.
External room Unit operation is decided by the external
thermostat thermostat or equivalent (e.g. heat pump
convector).
Room thermostat Unit operation is decided based on the ambient
temperature of the user interface used as a
room thermostat.
# Code
[2.9] [C‑07] ▪ 0: Leaving water
▪ 1: External room thermostat
▪ 2: Room thermostat
Setpoint mode
In Fixed mode, the desired leaving water temperature does NOT
depend on the outdoor ambient temperature.
In WD heating, fixed cooling mode, the desired leaving water
temperature:
▪ depends on the outdoor ambient temperature for heating
▪ does NOT depend on the outdoor ambient temperature for cooling
In Weather dependent mode, the desired leaving water temperature
depends on the outdoor ambient temperature.
# Code
[2.4] N/A Setpoint mode
▪ 0: Fixed
▪ 1: WD heating, fixed cooling
▪ 2: Weather dependent
When weather dependent operation is active, low outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user has the possibility to shift the
water temperature up or down by a maximum of 10°C.
Schedule
Indicates if the desired leaving water temperature is according to a
schedule. Influence of the LWT setpoint mode [2.4] is as follows:
▪ In Fixed LWT setpoint mode, the scheduled actions consist of
desired leaving water temperatures, either preset or custom.
▪ In Weather dependent LWT setpoint mode, the scheduled actions
consist of desired shift actions, either preset or custom.
# Code
[2.1] N/A ▪ 0: No
▪ 1: Yes
