Space heating operation ( )

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.

Selecting space heating operation

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

Icon appears on the display as well as the corresponding actual room temperature set point.

The operation LED lights up.

2 Use the temperature.

and buttons to set the desired room

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 12 for setup of the schedule timer function.

3 Use the and 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 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 16 for a detailed description how to

set one or more field settings.

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

1 Press the button 1 time to select weather dependent set point operation (or 2 times when the remote controller room thermostat function is used).

Icon appears on the display as well as the shift value. The shift value is not shown in case it is 0.

2 Use the and buttons to set the shift value.

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 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 icon will only be blinking during effective automatic storage operation. Presence of the permanently lit 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 button once.

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

The storage temperature set point and the timing are field settings.

"Domestic water heating modes" on page 7 ).

NOTE Remark that pushing the button has no influence on the domestic water heating. Domestic water heating is only switched on or off by means of the button and/or disabling the storage schedule timer.

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 icon will be blinking rapidly with 0.5

second intervals.

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

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

Be aware that after pushing the button, it is possible that the permanently lit 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 16

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 7 ).

[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.

Emergency operation

[8-02] Emergency operation

During emergency mode, heating is only done by the heater kit, not by the heat pump.

Activation of emergency mode is done by changing field setting

[8-02]=1.

Activating the emergency mode will stop the heat pump operation. The pump of the indoor unit will be started, but heating itself is done by the heater kit. If there are no error conditions in leaving or returning water thermistors, the heater kit can start to follow emergency operation.

NOTE Before activating emergency operation, be sure to activate the heater kit. The heater will stay in emergency mode until the field setting is set back to default [8-02]=0.

Other operation modes

Start up operation ( )

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

Defrost operation ( )

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 ( )

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 button to activate quiet mode operation.

The icon displays.

If the controller is set to permission level 2 or 3 (refer to "Field settings" in the installation manual), the button is not operable.

2 Press the button again to deactivate quiet mode operation.

The 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 16

for a detailed description how to set one or more field settings.

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

Space heating

Refer to

"Programming space heating" on page 13 .

Five actions per day of the week can be programmed, totalling 35 actions.

The space heating schedule timer can be programmed in 2 different ways: based on the temperature set point (both leaving water temperature and room temperature) and based on the ON/OFF instruction.

The desired method is set through field setting. Refer to the chapter

"Field settings" on page 16

for a detailed description how to set one or more field settings.

[0-03] Status: defines whether ON/OFF instruction can be used in the schedule timer for space heating.

NOTE By default space heating based on temperature set point (method 1) is enabled, so only temperature shifts are possible (no ON/OFF instruction).

Advantage of this method is that you can simply switch off the space heating operation by pushing the button without disabling the automatic domestic hot water storage operation (e.g. during summertime when no space heating is required).

In the following tables both methods on how to interpret the schedule timer are shown.

[0-03]=0 Space heating based on ON/OFF instruction

During operation When the schedule timer switches space heating OFF, the controller will be switched off (operation LED will stop working). Note that this has no influence on the domestic water heating.

When pushing the button

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.

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 14 .

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.

When pushing the / button

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 14 ). 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 14 .

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

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 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 ( 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.

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, depending on remote controller model 4 or 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, depending on remote controller model 4 or 5 actions can be programmed per mode. The same actions are repeated on a daily basis.

NOTE Remote controller model: 4 actions

Remote controller model: 5 actions

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 highest action number will be executed.

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.
