Applicable legislation: 3. All international, European, national and local directives, laws, regulations and/or codes which are relevant and applicable for a certain product or domain. 3.1. Accessories: Thank you for purchasing this indoor unit. Equipment which is delivered with the unit and which needs to be installed according to instructions in the documentation. Equipment which can optionally be combined to the products as per the subject of this manual.
. OPERATING 4.1. THE UNIT Introduction 4.2. Operating the EKHB* unit comes down to operating the digital controller. CAUTION The heat pump system is designed to provide you a comfortable indoor climate for many years at low energy consumption. Never let the digital controller get wet. This may cause an electric shock or fire. To get the most comfort with the lowest energy consumption out of your system, it is very important to observe the items listed below.
4.3. Name and function of buttons and icons 8 5 6 24 15 18 3 16 2 17 7 14 21 19 11 9 12 10 23 22 20 13 34 29 25 27 30 26 33 32 28 31 HEATING/COOLING ON/OFF BUTTON y The ON/OFF button starts or stops the heating or cooling function of the unit. When the unit is connected with an external room thermostat, this button is not operable and the icon e is shown. Pressing the ON/OFF button consecutively too many times may cause malfunction of the system (maximum 20 times per hour).
26. DOMESTIC WATER HEATING BUTTON v This button enables or disables heating of the domestic water. This button is not used when the domestic hot water tank is not installed. INFORMATION Remark that pushing the y button has no influence on the domestic water heating. Domestic water heating is only switched on or off by means of the v button. 27. WEATHER DEPENDENT SET POINT BUTTON ba This button enables or disables the weather dependent set point function which is available in space heating/cooling operation.
4.5. Description of the operation modes Only for [4-03]=4 or 5 In this mode, the indoor unit will heat up the domestic hot water tank. Space heating operation (h) In this mode, heating will be activated as required by the water temperature set point. The set point can be set manually (refer to "Manual operation" on page 7) or weather dependent (refer to "Selecting weather dependent set point operation" on page 7). There are several modes for heating up the domestic water tank: 1.
Quiet mode operation (s) 3 Switch on the unit by pushing the y button. The operation LED 0 lights up. Quiet mode operation means that the outdoor unit works at reduced capacity so that the sound produced by the outdoor unit drops. This implies that the indoor heating (cooling) capacity will also drop. Beware of this when a certain level of heating (cooling) is required indoors.
What can the schedule timer do? Displaying actual temperatures 1 2 Push the ba button for 5 seconds. The b icon and the entering water temperature are displayed. The icons l and = are flashing. The schedule timer allows the programming of: 1. Space heating (refer to "Programming space heating or domestic water heating" on page 10) Switch on the desired mode at a scheduled time, in combination with a set point (weather dependent or manually set).
INFORMATION The status of this setting is only mentioned to indicate which settings and functions are applicable for your application. 4.7. Programming and consulting the schedule timer Getting started [4-03]=0, 1, 2, 3, or 4 is only for domestic hot water tank with built-in electrical booster heater (EKHW*). 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).
Programming Programming space heating or domestic water heating Programming space heating or domestic water heating is carried out as follows: INFORMATION Returning to previous steps in the programming procedure without saving modified settings is done by pressing the pr button. 1 Press the < button. The actual mode is blinking. 2 Use the pi and pj buttons to select the mode you want to program (space heating h or domestic water heating w) 3 Press the < button to confirm the selected mode.
Programming space cooling, quiet mode, or booster heater mode(1) Programming space cooling, quiet mode, or booster heater mode (1) is carried out as follows: INFORMATION Returning to previous steps in the programming procedure without saving modified settings is done by pressing the pr button. 1 Press the < button. The actual mode is blinking. 2 Use the pi and pj buttons to select the mode you want to program (space cooling c, quiet mode s, or booster heating m(1)). The selected mode is blinking.
Consulting programmed actions To copy programmed actions to the next day, proceed as follows: 1 Press the < button. The actual mode is blinking. 2 Use the pi and pj buttons to select the mode you want to program. Consulting space heating or domestic water heating actions Consulting space heating or domestic water heating is carried out as follows. The selected mode is blinking. You can leave programming by pressing the pr button.
5. FIELD SETTINGS 5 Save the new value by pressing the pr button. 6 Repeat step 2 through 4 to change other field settings as required. 7 When finished, press the z button to exit FIELD SET MODE. NOTICE The default values mentioned in "Field settings table" on page 18 are the values from factory. The actual initial values shall be selected according to your application. These values shall be confirmed by your installer. CAUTION ■ The field settings [2] depends on the applicable legislation.
[1] Weather dependent set point [2] Disinfection function The weather dependent set point field settings define the parameters for the weather dependent operation of the unit. When weather dependent operation is active the water temperature is determined automatically depending on the outdoor temperature: low outdoor temperatures will result in warmer water and vice versa. During weather dependent operation, the user has the possibility to shift up or down the target water temperature by a maximum of 5°C.
Only for tank without electrical booster heater (EKHTS) Scheduled/continuous domestic hot water reheat According to local and national regulations, it may be required to disinfect the domestic hot water tank at a higher temperature (>60°C). In that case Daikin suggests to install a shunt pump and a heater element parallel on the domestic hot water tank according to the figure below.
INFORMATION ■ ■ Make sure the domestic 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 water is not heated unnecessary. Start with activating automatic storage during night (default setting).
[A] Quiet mode [E] Unit information readout This field setting allows to select the desired quiet mode. Two quiet modes are available: quiet mode A and quiet mode B. ■ [E-00] Readout of the software version (example: 23) In quiet mode A, priority is given to the outdoor unit operating quietly under all circumstances. Fan and compressor speed (and thus performance) will be limited to a certain percentage of the speed at normal operation. In certain cases, this might result in reduced performance.

6. MAINTENANCE 6.1. 6.3. NOTICE Important information regarding the refrigerant used 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. This product contains fluorinated greenhouse gases covered by the Kyoto Protocol. Switching off the power supply stops the automatic repetitive movement of the pump in order to prevent it from getting jammed.
