Description of the operation modes
Basic domestic water heating operation (w)
In this mode, the indoor unit will heat up the domestic hot water tank.
There are 2 basic domestic water heating modes: continuous mode
and scheduled timer mode. All heating will be activated as required
by the water temperature set point. The set point can be set manually
or auto adaptive (refer to "Auto adaptive set point operation" on
page 9).
Continuous operation
In continuous operation mode, the domestic water is always heated
up to the required set point. As soon as the domestic water
temperature is lower than the set point temperature (taking into
account the heat pump ON differential), the heating up of the
domestic water will start automatically. This operation mode remains
enabled until the schedule timer button is pressed (refer to "Schedule
timer operation" on page 7).
As the controller has a wide variety of functions, it is possible to
select a function which is restricted at a certain moment. In that case
the message n will appear.
Switching on domestic water heating (w)
1
Switch on the unit by pushing the Y button.
The operation LED 0 lights up.
2
For continuous operation the p icon must be OFF.
3
Use the wi and wj buttons to set the desired water
temperature.
The temperature range for heating is by default 35°C to 60°C.
This means that in default operation only the heat pump will heat
up the water.
For temperatures higher than 60°C (until 75°C maximum) refer
to the field settings explained in the installation manual.
In order to avoid freezing of installation space, heating by the
heat pump is not operable when the indoor ambient temperature
drops below a certain temperature (refer to the field settings
explained in the installation manual). The booster heater will
take over the heating process.
INFORMATION
1
Hold down the pr button for 5 seconds.
The clock read-out and the day of week indicator start flashing.
The domestic hot water temperature set point can also be
auto adaptive (icon a is shown).
2
Use the pi and pj buttons to adjust the clock.
This means that the controller calculates the water
temperature set point based on the history of use of
domestic hot water.
Each time the pi or pj button is pressed, the time will
increase/decrease by 1 minute. Keeping the pi or pj
button pressed will increase/decrease the time by 10 minutes.
3
Use the wi or wj button to adjust the day of the week.
Each time the wi or wj button is pressed the next or
previous day is displayed.
4
Press the < button to confirm the current set time and day of the
week.
To leave this procedure without saving, press the pr button.
If no button is pressed for 5 minutes the clock and day of the
week will return to their previous setting.
The clock needs to be set manually. Adjust the setting
when switching from summertime to wintertime and vice
versa.

Schedule timer operation
What can the schedule timer do?
In schedule timer operation, the installation is controlled by the
schedule timer. The actions programmed in the schedule timer will be
executed automatically.
The schedule timer allows the programming of:
1.
Domestic water heating (refer to "Programming domestic water
heating" on page 10)
Switch on the domestic water heating mode at a scheduled time
on or off in combination with a set point (auto adaptive or
manually set). Five actions per weekday can be programmed,
totalling 35 actions. When manual set point operation is required
for each action, a set point can be chosen. If the auto adaptive
button (ba) is pressed, all set points of the programmed
schedule timer will be auto adapted.
2.
Quiet mode (refer to "Programming quiet mode" on page 11)
Switch the mode on or off at a scheduled time. Five actions can
be programmed for this mode. These actions are repeated daily.
INFORMATION
Default: the schedule timer is set as follows.
Time
Set point
temperature
Sunday until thursday
7~4
22~6 h
45°C
Friday and saturday
5+6
22~6 h
55°C
If this does not fullfill the customers demands, it has to be
set as explained in "Programming and consulting the
schedule timer" on page 9.
INFORMATION
The schedule timer always follows the last command until a new
command is given. This means that the user can temporarily overrule
the last programmed set point by manual operation (by pressing the
wi and wj buttons). Only during the period when the
schedule timer is active, this overruling action is possible. If schedule
timer heating is not active, it will only be possible to observe and not
to adjust the scheduled set point.
The schedule timer is enabled (p icon displayed) or disabled (p icon
not displayed), by pressing the pr button. When it is disabled the
unit will work in continuous operation.
INFORMATION
■
Only use the pr button to enable or disable the
schedule timer.
■
If the auto restart function is disabled, the schedule
timer will not be activated when power returns to the
unit after a power supply failure. Press the pr button
to enable the schedule timer again.
■
When power returns after a power supply failure, the
auto restart function reapplies the user interface
settings at the time of the power supply failure.
It is therefore recommended to leave the auto restart
function enabled.
INFORMATION
■
The programmed schedule is time driven. Therefore, it
is essential to set the clock and the day of the week
correctly. Refer to "Setting the clock" on page 6.
■
Manually adjust the clock for summertime and
wintertime. Refer to "Setting the clock" on page 6.
■
A power failure exceeding 2 hours will reset the clock
and the day of the week. The schedule timer will
continue operation, but with a disordered clock. Refer
to "Setting the clock" on page 6 to adjust the clock
and the day of the week.
■
The actions programmed in the schedule timer will not
be lost after a power failure so that reprogramming the
schedule timer is not required.
The programmed actions are not stored according to their
timing but according to the time of programming. This
means that the action that was programmed first gets
action number 1, even though it is executed after other
programmed action numbers.
How to interpret the programmed actions
To be able to understand the behaviour of your installation when the
schedule timer is enabled, it is important to keep in mind that the
"last" programmed command overruled the "preceding" programmed
command and will remain active until the "next" programmed
command occurs.
Example: imagine the actual time is 17:30 and actions are
programmed at 13:00, 16:00 and 19:00. The "last" programmed
command (16:00) overruled the "previous" programmed command
(13:00) and will remain active until the "next" programmed command
(19:00) occurs.
So in order to know the actual setting, one should consult the last
programmed command. It is clear that the "last" programmed
command may date from the day before. Refer to "Consulting
programmed actions" on page 12.
INFORMATION
During schedule timer operation, someone may have
altered the actual settings manually (in other words, the
"last" command was overruled manually). The icon p,
indicating the schedule timer operation, may still be
displayed, giving the impression that the "last" command
settings are still active. The "next" programmed command
will overrule the altered settings and return to the original
program.
INFORMATION
■
When changing from continuous operation mode to
schedule timer operation mode, the unit applies the
scheduled set point.
■
When changing from schedule timer operation mode
to continuous operation mode, the unit will keep the
latest set point of the schedule timer operation mode.
Beware to manually adjust the set point if required.
To set up the SCHEDULE TIMER refer to chapter "Programming and
consulting the schedule timer" on page 9.

In heat pump domestic water heating operation, freezing of the air
heat exchanger may occur due to low ambient temperature. If this
risk occurs, the system goes into defrost operation. It takes heat from
the compressor to undo freezing of the heat exchanger. After a
maximum of 20 minutes of defrost operation, the system returns to
domestic water heating operation.
Disinfection operation
This mode will disinfect the domestic hot water tank by periodically
heating the domestic water to a specific temperature. During the
operation of this mode the w icon will be blinking slowly with
0.5 second intervals.

Programming the schedule timer is flexible (you can add, remove or
alter programmed actions whenever required) and straightforward
(programming steps are limited to a minimum). However, before
programming the schedule timer, remind:
■
Familiarise yourself with the icons and the buttons. You will need
them when programming. Refer to "Name and function of
buttons and icons" on page 5.
■
Fill out the form at the very end of this manual. This form can
help you define the required actions for each day. Keep in mind
that:
- In the domestic water heating program, 5 actions can be
programmed per weekday. The same actions are repeated
on a weekly basis.
- In the quiet mode program, 5 actions can be programmed.
The same actions are repeated on a daily basis.
■
Take your time to enter all data accurately.
■
Try to program the actions in a chronological way: start with
action 1 for the first action and end with the highest number for
the last action. This is not a requirement but will simplify the
interpretation of the program later.
■
If 2 or more actions are programmed for the same day and at the
same time, only the action with the lowest action number will be
executed.
■
You can always alter, add or remove the programmed actions
later.
INFORMATION
■
When the auto adaptive set point function is activated,
all set points that have been manually put in the
schedule timer will be replaced by the automatic
calculated set point.
When the auto adaptive set point is deactivated again,
the schedule timer will work again according to the
originally programmed set points.
■
Programming and consulting the schedule timer
The auto adaptive set point operation function will
work at his best when the customer has a domestic
hot water tapping pattern on a regular basis. If the
demand deviation is too big, shortage of hot water can
occur. The demand expectation is based on maximum
domestic hot water use of the past weeks.
If a permanent change in domestic hot water demand
requirement occurs, the automatic set point
calculation must tbe reset ([8-03], refer to the field
settings explained in the installation manual).
■
Make sure that the field setting of the volume of the
domestic hot water tank is set correct (refer to the field
settings explained in the installation manual).
■
Make sure to put the unit on stand-by during longer
periods of absence.
If this is not done, the auto adaptive set point wiil
continue to be calculated, resulting in incorrect
settings not representing the normal domestic hot
water demands of the user.
■
Auto adaptive set point will not work optimal if very
large amounts of domestic hot water are used each
day by frequently heating up water during the day.
■
Reheat operation, powerful operation and disinfection
operation overrule auto adaptive set point and heat up
the domestic hot water tank to their respective set
point.

FIELD
SETTINGS
INFORMATION
Changes made to a specific field setting are only stored
when the pr button is pressed. Navigating to a new field
setting code or pressing the z button will discard the
change made.
NOTICE
The default values mentioned in "Field settings table" on
page 15 are the values from factory. The actual initial
values shall be selected according to your application.
These values shall be confirmed by your installer.
The unit shall be configured by the installer to match the installation
environment (insulation of the house, etc.) and user demand.
However, the field settings [0] and [1] mentioned in "Field settings
table" on page 15 can be modified to customer preferences. Thereto,
a number of so called field settings are available. These field settings
are accessible and programmable through the user interface on the
indoor unit.
Each field setting is assigned a 3-digit number or code, for example
[1-03], which is indicated on the user interface display. The first digit
[1] indicates the 'first code' or field setting group. The second and
third digit [03] together indicate the 'second code'.
INFORMATION
Before shipping, the set values have been set as shown
under "Field settings table" on page 15.
Detailed description
To understand the field setting possibilities explained in the following
chapters, understand that different domestic hot water tank operation
modes are possible.
■
■ If the P button is pressed, the heat pump module heats up
the domestic hot water tank as fast as possible to a
predefined setpoint.
This means that the inverter
compressor frequency will be higher then in normal operation
mode and that sound level and power consumption can be
higher.
This mode might be usefull when exceptional high hot water
consumption depletes all the available domestic hot water
and hot water is required.
A list of all field settings and default values is given under "Field
settings table" on page 15. In this same list, we provided for 2
columns to register the date and value of altered field settings at
variance with the default value.
A detailed description of field settings [0] and [1] are given under
"Detailed description" on page 13, the other field settings are
exclusively described in the installation manual.

MAINTENANCE
Important information regarding the refrigerant
used
The only maintenance which may be required by the operator is:
■
keeping the remote controller clean by means of a soft damp
cloth,
■
A check for correct operation of the field installed pressure relief
valve installed on your domestic hot water tank, has to be
carried out at least every 6 months: it is important that the lever
on the valve is actuated to prevent accumulation of mineral
deposits that may impair valve operation and to confirm that the
valve and discharge pipe are not blocked. The lever should be
operated slowly and smoothly to avoid a sudden rush of hot
water from the discharge pipe.
Failure to operate the relief valve actuating lever may result in
the water heater exploding.
■
Continuous leakage of water from the discharge pipe may
indicate a problem with the water heater.
■
If a discharge pipe is connected to the pressure relief device it
must be installed in a continuously downward direction and in a
frost-free environment. It must be left open to the atmosphere.
This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol.
Refrigerant type:

GWP = global warming potential
Periodical inspections for refrigerant leaks may be required
depending on European or local legislation. Please contact your local
dealer for more information.
7.2.
Maintenance activities
In order to ensure optimal availability of the unit, a number of checks
and inspections on the unit and the field wiring have to be carried out
at regular intervals, preferably yearly.
■
Each inspection has to be carried out by your local
Daikin technician and not by the user.
■
Do not touch water pipes immediately after operation
as the pipes may be hot. Your hand may suffer burns.
To avoid injury, give the piping time to return to normal
temperature or be sure to wear proper gloves.
WARNING
■
Before carrying out any maintenance or repair activity,
always switch off the circuit breaker on the supply
panel, remove the fuses or open the protection
devices of the unit.
■
Do not touch live parts for 10 minutes after the power
supply is turned off because of high voltage risk.
■
Do not touch any switch with wet fingers. Touching a
switch with wet fingers can cause electrical shock.
■
Please note that some sections of the electric
component box are hot.
■
Make sure you do not touch a conductive section.
■
Do not rinse the unit. This may cause electric shocks
or fire.
7.3.
Standstill

■
If the domestic hot water is not used for two weeks or more, a
quantity of hydrogen gas which is highly flammable may
accumulate in the domestic hot water tank. To dissipate this gas
safely, it is recommended that a hot tap be turned on for several
minutes at a sink, basin, or bath, but not at a dishwasher,
clothes washer or other appliance. During this procedure there
must be no smoking, open flame or any electrical appliance
operating nearby. If hydrogen is discharged through the tap, it
will probably make a sound as of air escaping.
Play it safe!
Touch a metal part by hand (such as the stop valve) in
order to eliminate static electricity and to protect the PCB
before performing service.
WARNING
■
Do not touch water pipes during and immediately after
operation as the pipes may be hot.
■
Do not touch the refrigerant pipes during and
immediately after operation as the refrigerant pipes
may be hot or cold, depending on the condition of the
refrigerant flowing through the refrigerant piping,
compressor, and other refrigerant cycle parts.
Your hands may suffer burns or frostbite if you touch the
pipes. To avoid injury, give the pipes time to return to
normal temperature or, if you must touch them, be sure to
wear proper gloves.
