7.5 Parameter settings
All parameters of the control are described in detail in this
section. An overview of all parameters, their factory settings and
setting ranges are listed in Tab. 7-5.
7.5.1 Setting parameters
Each parameter/function is allocated a 3-digit code (e.g. [0-03]),
which is displayed on the controller display (Fig. 7-4, Item 2).
The first number [0] shows the parameter group (Code 1 in
Tab. 7-5). The second and third number [03] show the relevant
parameter in this group of parameters (Code 2 in Tab. 7-5).
1. Press
key for at least 5 s.
The icon
is displayed.
The current parameter code
is displayed (Fig. 7-4,
Item 2).
The set parameter value
of the relevant parame-
ter code is displayed (Fig. 7-4, Item 1).
2. Use the
key to select the parameter group.
3. Use the
key to select the parameter to be set.
4. Use one of the
or
keys to change the setting
of the parameter selected.
5. Press the
key to save the value.
6. Repeat steps 2 to 5 to set other parameters or press the
key briefly to exit the parameter setting mode.
7.5.2 Parameter description
[0] - Temperature settings operating modes
The following setting options are available:
– [0-00] Hot water set temperature for the operating mode "High
Output".
– [0-01] Hot water set temperature for the thermal disinfection
of the hot water storage tank (Legionella protection).
– [0-02] Set value heat retention function. This set value is
taken up as soon as the DAIKIN is in an "OFF" period and
serves to maintain a minimum storage tank temperature. The
DAIKIN hot water heat pump starts as soon as the water tem-
perature in the storage tank has fallen below the temperature
hysteresis (depending on the operating mode and setting).
– [0-03] Switch-off temperature heat retention function: Tem-
perature at which the DAIKIN hot water heat pump stops the
reheating procedure.
– [0-04] Activation temperature heat retention function: Deter-
mines whether automatic reheating takes place if the temper-
ature falls below the parameter value [0-02].
– 0 = Function is switched off
– 1 = Function is switched on
[2] - Thermal disinfection (Legionella protection)
The following setting options are available:
– [2-00] Start day: Day of the week on which the function should
be started.
– [2-01] Automatic disinfection with switched on hot water heat
pump:
– 0 = No disinfection
– 1 = Automatic disinfection
– [2-02] Starting time: Time of day at which the function should
be started.
– [2-03] Automatic disinfection in "Stand-by Mode":
– 0 = No disinfection
– 1 = Automatic disinfection
– [2-04] Holding time: Length of time the disinfection tempera-
ture must be maintained.
DAIKIN recommends you note all changes to the pa-
rameters and switching times in the tables in Section
7.5.4 and Section 7.5.5.

Parameter setting on the controller
In order to set the parameter groups 2 to C (area
marked in grey in Tab. 7-5) ("Advanced Mode") you
need to push the
key again for at least 10 sec.
Changes to parameters are only saved if the
key is pressed. Changing to a new parameter code
or pressing the
key rejects the changes made.
WARNING!
The settings of the Legionella protection
must always be configured in accordance
with the country-specific laws.
If no hot water is used for several days and the
storage temperature of the DAIKIN does not reach
at least 60 °C, for hygiene reasons (Legionella pro-
tection) it is periodically heated up to above 60 °C
once.
An ON temperature > 45 °C makes sure that only the
electricBooster-Heater (BSH) is used and not the heat
pump. This increases the usage duration of the refrig-
erant compressor.
If the temperature in the storage tank falls because of a
draw-off, the thermal disinfection will be restarted.
If thermal disinfection is prevented, e.g. by the high-tariff signal,
(Booster-Heater (BSH) blocked), this is carried out as soon as
the DAIKIN hot water heat pump is in the normal mode again
(see Tab. 7-3).
