■ A power failure exceeding 1 hour will reset the clock and the day of the week. The schedule timer will continue operation, but with a disordered clock. Therefor it will be needed to correct the clock and the day of the week.

Space heating operation (h)

Space heating operation can be controlled on two different ways:

- based on room temperature,

- based on leaving water temperature.

The purpose of each operation and how the conﬁguration is done, is explained below.

Room temperature control

In this mode, heating will be activated as required by the room temperature set point. The set point can be set manually or through the schedule timer.

NOTE

When using room temperature control, space heating operation based on room temperature will have priority over leaving water control.

Note that it is possible that the leaving water temperature becomes higher than the set point if the unit is controlled by room temperature.

The operation LED 0 lights up.

2 Use the bi and bj buttons to set the desired room

temperature. Temperature range for heating: 16°C~32°C (room temperature) In order to avoid overheating, space heating is not operable

when the outdoor ambient temperature rises above a certain temperature (see operation range).

Refer to "Programming and consulting the schedule timer" on

page 11 for setup of the schedule timer function.

3 Use the ébi and ébj buttons to select the leaving

water temperature which you want to be used to heat up your system (for detailed information see "Leaving water temperature

control" on page 5).

Automatic setback function

Setback function provides the possibility to lower the room temperature. The setback function can for instance be activated during the night because the temperature demands during night and day are not the same.

NOTE

■ Remark that the b icon will be ﬂashing during setback operation.

■ By default the setback function is enabled.

■ The setback function can be combined with the

automatic weather dependent set point operation.

■ Setback function is an automatic daily scheduled function.

The setback function is conﬁgured through ﬁeld settings. Refer to the chapter "Field settings" on page 14 for a detailed description how to set one or more ﬁeld settings.

NOTE

While room temperature setback function is active, leaving water setback operation is also performed (see

"Leaving water temperature control" on page 5).

Pay attention not to set the setback value too low, especially during colder periods (e.g. winter time). It is possible that the room temperature can not be reached (or it will take a much longer time) because of the big temperature difference.

Leaving water temperature control

In this mode, heating will be activated as required by the water temperature set point. The set point can be set manually, through the schedule timer or weather dependent (automatic).

Selecting space heating operation

1 Use the y button to switch ON/OFF space heating (h).

Icon h appears on the display as well as the corresponding water temperature set point.

The operation LED 0 lights up.

2 Use the ébi and ébj buttons to set the desired leaving

water temperature. Temperature range for heating: 25°C~80°C (leaving water

temperature) In order to avoid overheating, space heating is not operable

when the outdoor ambient temperature rises above a certain temperature (see operation range).

Refer to "Remote controller schedule timer" for setup of the schedule timer function.

NOTE

Selecting weather dependent set point operation

When weather dependent operation is active, the leaving water temperature is determined automatically depending on the outdoor temperature: colder outdoor temperatures will result in warmer water and vice versa. The unit has a ﬂoating set point. Activating this operation will result in a lower power consumption than use with a manually ﬁxed leaving water set point.

During weather dependent operation, the user has the possibility to shift up or down the target water temperature by a maximum of 5°C. This shift value is the temperature difference between the temperature set point calculated by the controller and the real set point. E.g. a positive shift value means that the real temperature set point will be higher than the calculated set point.

It is advised to use the weather dependent set point because it adjusts the water temperature to the actual needs for space heating. It will prevent the unit from switching too much between thermo ON operation and thermo OFF operation when using the remote controller room thermostat or external room thermostat.

NOTE

1 Press the ba button 1 time to select weather dependent set

2 Use the ébi and ébj buttons to set the shift value.

3 Press the ba button to deactivate weather dependent set point

■ When an external room thermostat is installed, the thermo ON/OFF is determined by the external room thermostat. The remote controller is than operated in the leaving control mode and is not functioning as a room thermostat.

■ The remote controller ON/OFF status always has priority over the external room thermostat!

During this operation, instead of showing the water temperature set point, the controller shows the shift value which can be set by the user.

Automatic storage

In this mode, the indoor unit will deliver hot water to the domestic hot water tank based on the daily ﬁxed pattern. This mode will continue until the storage temperature set point is reached. During operation of this mode, the w icon will be blinking with 1 second intervals.

Automatic storage is the recommended domestic hot water mode. In this mode, water heats up during the night (when space heating requirements are lower) until the storage temperature set point is reached. The heated water is stored in the domestic hot water tank at a higher temperature so it can fulﬁl the domestic hot water requirements throughout the day.

NOTE

Remark that the w icon will only be blinking during effective automatic storage operation. Presence of the permanently lit w icon does not mean that automatic storage is enabled, but only means that reheat is enabled.

During operation it is always possible to cancel the operation by pushing the w button once.

Be aware that after pushing the w button, it is possible that the permanently lit w icon still displays.

The storage temperature set point and the timing are ﬁeld settings. Refer to the chapter "Field settings" on page 14 for a detailed description how to set one or more ﬁeld settings.

■ [1-03] Start time: time of the day at which the domestic water should be heated.

Be aware that despite the automatic storage is a pre-programmed schedule timer, it is only active when the schedule timer is enabled. This means that you have to push the rp button and conﬁrm that the p is displayed to make sure that the automatic storage will operate.

■ [b-03] set point: storage temperature (see ﬁgure "Domestic

water heating modes" on page 6).

■ [b-02] Status: deﬁnes whether the weather dependent domestic water heating is turned ON (1) or OFF (0).

If enabled, the storage set point will be set weather dependent. In case of a higher ambient temperature (e.g. during summertime), temperature of supply water to the domestic hot water tank will be higher too, so that storage temperature set point can be set lower in order to keep the overall equivalent hot water amount the same during the whole year. Therefor it is recommended to use this function.

NOTE

■ Make sure the domestic hot water is only heated up to the domestic hot water temperature you require.

Start with a low domestic hot water storage temperature set point, and only increase if you feel that the domestic hot water supply temperature is not sufﬁcient for your needs (this depends on your water using pattern).

■ Make sure the domestic hot water is not heated unnecessary. Start with activating automatic storage during night (default setting). If it seems that the domestic hot water night storage operation is not sufﬁcient for your needs, an additional storage during daytime can be set.

■ For energy-saving purposes, it is advised to enable the weather dependent domestic water heating.

Manual storage

This mode is to be selected manually and will make the indoor unit immediately deliver hot water to the domestic hot water tank. This mode will continue until the storage temperature set point is reached. It is a one-time hot water making feature.

NOTE

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 rapidly with 0.5 second intervals.

Other operation modes

Start up operation (d)

During start up, the d icon displays, indicating that the heat pump is starting up and is not working in a steady state condition.

Defrost operation (d)

In space heating operation or domestic water heating operation, freezing of the outdoor heat exchanger may occur due to low outdoor temperature. If this risk occurs, the system goes into defrost operation. It reverses the cycle and takes heat from the indoor system to prevent freezing of the outdoor system. After a maximum of 12 minutes of defrost operation, the system returns to space heating operation.

Quiet mode operation (s)

Quiet mode operation means that the indoor unit works at reduced compressor speed so that the noise produced by the indoor unit drops. This implies that it will take longer till the required temperature set point is reached. Beware of this when a certain level of heating is required indoors.

Selecting quiet mode operation

1 Use the s button to activate quiet mode operation.

The s icon displays. If the controller is set to permission level 2 or 3 (refer to "Field

settings" in the installation manual), the s button is not operable.

2 Press the s button again to deactivate quiet mode operation.

The s icon disappears.

There are 3 different levels of quiet mode operation. The desired quiet mode is set through a ﬁeld setting. Refer to the chapter "Field

settings" on page 14 for a detailed description how to set one or more

ﬁeld settings.

■ [8-03] Status: deﬁnes the level of low noise operation (quiet mode).

NOTE

Remark that the w icon will only be blinking during effective operation.

During the operation it is always possible to cancel the disinfection function by pushing the w button once.

Be aware that after pushing the w button, it is possible that the permanently lit w icon still displays, meaning that the reheat function is enabled.

NOTE

If a domestic hot water tank is installed, the disinfection function is enabled by default.

The disinfection temperature set point is a ﬁeld setting as are the retention time, day and hour. Refer to the chapter "Field settings" on

page 14 for a detailed description how to set one or more ﬁeld

settings.

■ [4-00] Status: deﬁnes whether the disinfection function is turned ON (1) or OFF (0).

■ [4-01] Operation interval: day of the week at which the domestic water should be heated.

■ [4-02] Start time: time at which the disinfection operation is started.

■ [5-00] Set point: Disinfection water temperature to be reached (see ﬁgure "Domestic water heating modes" on page 6).

■ [5-01] Duration: time period deﬁning how long the disinfection set point temperature should be maintained.

Even if all schedule timers are de-activated and there is no reheat function active, the disinfection function will operate if a domestic hot water tank is installed and ﬁeld setting [4-00] is set to ON.

Simultaneous demand of space heating and domestic water heating

The unit can not perform domestic water heating and space heating at the same time. If both modes are requested at the same time, the unit will heat up till the reheat maximum temperature in 1 time. During this period, space heating is not possible.

■ If you are using the remote controller room temperature control: When the reheat temperature is reached, the further heat up of

the domestic hot water tank will be decided by the remote controller room thermostat in order to prevent the room temperature to drop too much.

■ If you are using the external room thermostat: When the reheat temperature is reached, the further heat up of

the domestic hot water tank will be decided by the external room thermostat thermo conditions and running timers which are programmed by your installer.

■ If you are using the remote controller leaving water temperature control:

When the reheat temperature is reached, the further heating up of the domestic hot water tank will be decided by the running timers which are programmed by your installer.

the controller will be switched off (operation LED will stop working). Note that this has no inﬂuence on the domestic water heating.

The schedule timer for space heating will stop (when active at that moment) and will start again at the next scheduled ON function. The "last" programmed command overrules the "preceding" programmed command and will remain active until the "next" programmed command 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 13.

The controller will be switched off (operation LED will stop working).

However the schedule timer icon will stay displayed which means that the domestic heating stays enabled.

The schedule timer for space heating and domestic water heating along with the quiet mode will be stopped and will not start again.

The schedule timer icon will not be displayed anymore.

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.

Operation manual

Page 12

Domestic water heating

Domestic water heating can be done through several standard operation modes:

•Automatic storage: by ﬁeld setting, once during night and/or once during the afternoon the water is heated till storage set point.

• Manual storage: if due to special circumstances, production of hot water (till storage set point) is needed immediately (1 time), this function can be used.

• Reheat: the reheat function can be activated next to or separate from the automatic storage operation if the user wants to keep the domestic hot water tank at the minimum reheat temperature.

Next to the standard domestic water heating operation modes, it is also possible to freely program the domestic water heating operation through the schedule timer (refer to "Programming quiet mode or

domestic water heating" on page 13). Then the mode is switched on

or off at a scheduled time. Five actions can be programmed per mode. These actions are repeated daily (additional schedule of storage on top of the automatic day and night storage functionality).

NOTE

■ Remark that only the time when domestic water heating must start and stop can be programmed in the schedule timer. When domestic water heating is enabled, the water will be heated till storage set point. The storage set point is set through ﬁeld setting.

■ For energy-saving reasons, keep hours with low electricity cost tariffs in mind when programming the schedule timer for domestic water heating.

Quiet mode

Refer to "Programming quiet mode or domestic water heating" on

page 13.

Switch the mode on or off at a scheduled time. Five actions can be programmed per mode. These actions are repeated daily.

Programming and consulting the schedule timer

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:

■ Familiarize yourself with the icons and the buttons. You will need them when programming. Refer to "Remote controller buttons

and icons" on page 3.

■ 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 space heating program, 5 actions can be programmed

per weekday. The same actions are repeated on a weekly basis.

- In the domestic water heating and quiet mode program, 5

actions can be programmed per mode. The same actions are repeated on a daily basis.

■ Ta ke your time to enter all data accurately.

■ Tr y 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 highest action number will be executed.

Example:

NOTE

■ 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 (if time is shorter than 2 hours). It is therefore recommended to leave the auto restart function enabled.

■ 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 4.

■ When the schedule timer is not enabled (p icon not displayed), schedule timer actions will not be executed!

■ 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.

■ You can always alter, add or remove the programmed actions later.

Field settings

The conﬁguration of the Daikin system is done through ﬁeld settings. In this operation manual all ﬁeld settings related to the operation of

the unit and user demand are explained. A list of all those 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.

For a total list of ﬁeld settings, refer to the installation manual. All 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

[5-03], which is indicated on the user interface display. The ﬁrst digit [5] indicates the 'ﬁrst code' or ﬁeld setting group. The second and third digit [03] together indicate the 'second code'.

Procedure

To change one or more ﬁeld settings, proceed as follows.

Operating the remote alarm option

An optional EKRP1HBA digital I/O PCB can be connected to the indoor unit and be used to remotely monitor your system. This address card offers 3 voltage free outputs:

■ Output 1 = THERMO ON/OFF this output will be enabled when your unit is in space heating

operation.

■ Output 2 = ALARM OUTPUT this output will be enabled when your unit is in error condition.

■ Output 3 = DOMESTIC HOT WATER MODE ON/OFF this output will be enabled when your unit is in domestic water

heating operation.

For more details about the wiring connections of this option, refer to the wiring diagram of the unit.

Operating the optional remote controller

MAINTENANCE

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. This maintenance should be carried out by your local Daikin technician (see installation manual).

The only maintenance which may be required by the operator is:

■ keeping the remote controller clean by means of a soft damp cloth,

■ checking if the water pressure indicated on the manometer is above 1 bar.

If the supply cord is damaged, it must be replaced by the manufacturer, its agent or similar qualiﬁed persons in order to avoid hazards.

During longer periods of standstill, e.g. during summer with a heating only application, it is very important NOT TO SWITCH OFF THE POWER SUPPLY towards the unit.

Switching off the power supply stops the automatic repetitive movement of the pump in order to prevent it from getting jammed.
