IMPORTANT This product is intended for domestic use only.

The manufacturer Daikin Europe NV accepts no liability for damage or injury caused by the failure to (strictly) observe the safety instructions, or negligence during the installation of the Daikin EKOMB*AAV1H wall-mounted gas boiler and any associated accessories.

This device is not intended for use by people (including children) with reduced physical, sensory or mental abilities, or lack of experience and knowledge, unless they are given supervision or instructions on the use of the device by a person who is responsible for their safety.

The entire installation must meet the applicable local technical and (safety) instructions, for the gas installation, the electrical installation, smoke extraction installation, drinking water installation, and central heating installation.

2 UNIT DESCRIPTION

2.1 General

The Daikin EKOMB*AAV1HAAV1H wall-mounted gas boiler is a closed unit. The unit is intended to provide heat to the water of a CH installation and the domestic hot water installation.

The air supply and combustion gas outlet can be connected to the unit by means of two separate pipes. A concentric connection can be supplied upon demand. The unit was tested in combination with the combi feedthrough, but the unit may also be connected to combi feedthroughs which meet the universal test standards for combi feedthroughs.

The unit can be connected to an assembly bracket if required, a frame with top connection, and various installation sets. These are provided separately.

The Daikin EKOMB*AAV1H wall-mounted gas boilers have the CE quality mark, electrical protection class IP44.

It is possible to use the unit solely for warm water, or solely for heating. The system which is not in use, does not need to be connected (see par. 7.2). The unit is delivered for natural gas (G20) as a standard. On request, the unit can also be provided for propane (G31).

2.2 Functioning

The Daikin EKOMB*AAV1H wall-mounted gas boiler is a modulating high-efficiency boiler. This means that the power is modulated to suit the required heat demand. In the aluminum heat exchanger two separate copper circuits are integrated.

The separate circuits for CH and warm water allow the heating and warm water supply to function independently. The hot water supply takes precedence over the heating. Both cannot work at the same time.

The unit is fitted with an electronic boiler controller machine, which operates the fan at every heat requirement of the heating or the warm water supply, opens the gas valve, ignites the boiler controller, and continuously monitors and regulates the flame, depending on the requested power.

Daikin Europe NV 5

2.3 Operating modes

The operating mode of the unit is indicated by means of a code on the service display of the operating panel.

- Off

The unit is not in operation, but is connected to the electricity supply. No response is given to requests for domestic hot water or CH water. The unit frost protection is active. This means that the pump will start running and the exchanger will be heated up if the temperature of the water in the system drops too far.

If the frost protection intervenes, the code 7 will be displayed (heating up exchanger). The pressure in the CH installation can also be read from the temperature display in this

operating mode (in bar).

Standby

The LED at the key is lit and possibly one of the LEDs of the tap comfort function. The unit is ready to respond to a request for CH or tap water.

Post-running CH

After the end of the CH operation, the pump will run for a specified time. The post-pumping time is set to the value in par. 7.2 in its factory settings. This setting can be changed. In addition to this, the pump will run automatically 1 time per 24 hours, for 10 seconds, in order to prevent it from getting stuck. This automatic switching on of the pump takes place at the time of the last heating request. In order to change this, the room thermostat needs to be set higher for a moment, at the required time of day.

1 Requested temperature reached

The boiler controller may temporarily block the heat request. The boiler controller will then be stopped. The block occurs because the required temperature has been reached. When the temperature has sufficiently decreased, the block will be lifted.

2 Self test

Once every 24 hours, the boiler controller tests the connected sensors. During the test, the controller will not carry out any other tasks.

3 Ventilating

When the unit is started, the fan is first brought up to its correct start rpm. When the start rpm is reached, the boiler controller will be ignited. Code 3 is also visible when

there is post-fanning after the boiler controller is stopped.

4 Igniting

When the fan has reached the start rpm, the boiler controller will be ignited by means of electrical sparks. During the ignition, code 4 is displayed. If the boiler controller does

not ignite, a new attempt will be made after approximately 15 seconds. If after 4 ignition attempts, the boiler controller has still not been ignited, the controller will go into downtime.

5 CH operation

An on/off thermostat, an OpenTherm thermostat, an outdoor sensor or a combination thereof can be connected to the controller (see par. 10.1).

When there is a heat request from a thermostat, after the fan has started running (code 3), the ignition will take place (code 4 ) followed by the CH operating mode (code 5 ).

During CH operating, the rpm of the fan and therefore the power of the unit can be adjusted so the temperature of the CH water to the required CH supply temperature can be controlled. If an on/off thermostat has been connected, this will be the CH supply temperature set on the display. In case of an OpenTherm thermostat, the required CH supply temperature is determined by the thermostat. In case of an outdoor sensor, the required CH supply temperature is determined by the fuel line programmed in the boiler controller. For the last two situations, the temperature set on the display is the maximum.

During CH operation, the requested CH supply temperature will be displayed on the operating panel.

The CH supply temperature can be set between 30 and 90°C (see par. 7.1). Caution: for a low temperature system, a lower maximum setting may be required than the standard setting of 80°C.

You can press the service button during CH operation to read the actual CH supply temperature.

If the tap comfort function is switched on (see code 7 ), an OpenTherm heating request of less than 40 degrees will be generated.

6 Tap water operation

The hot water supply takes precedence over the heating. If the flow switch senses a request for more than 2 l/min of domestic hot water, any CH requests will be

interrupted. After the fan has switched on (code 3 ) and there has been an ignition (code 4 ), the controller will switch to domestic water operation (code 6 ). During

domestic hot water operation, the rpm of the fan, and therefore the power of the unit, is controlled by the controller on the basis of the set tap water temperature.

The control system ensures the tap water temperature is correct. The water temperature can be set between 40°C and 65°C (see par. 7.1). The set tap water temperature is displayed on the operation panel. The standard setting is 60°C.

You can press the service button during tap water operation to read the actual tap water temperature.

7 Heating up unit

In order to provide a fast supply of domestic hot water, a so-called tap comfort function has been installed in the unit. This function keeps the heat exchanger at the right temperature (this temperature can be set, see par. 7.2). The tap comfort function has the following settings:

• On: ( LED on) The tap comfort function of the unit is continuously switched on.

The unit always immediately provides warm water.

• Eco: ( LED on) The tap comfort function of the unit is self-learning. The unit will

adjust to the usage pattern of the domestic hot water. This means the heat exchanger will not be kept warm during the night or during longer absences.

• Off: (Both LEDs off) The heat exchanger is not kept warm which means the supply of

domestic hot water takes a bit of time. If there is no need for fast delivery of domestic hot water, the tap comfort function can be switched off.

2.4 PC Interface

The boiler controller is provided with an interface for a PC. A PC can be connected by means of a special dongle, and the associated software. This facility enables you to follow the behavior of the boiler controller, the unit and the heat installation over a long period.

2.5 Test programs

There is an option in the boiler controller, to bring the unit into a test status. Activating a test program, will switch on the unit with a set fan rotations per minute,

without the control functions intervening. The safety functions do remain active. The test program is ended by pressing and simultaneously.

Test programs

During test mode the following data can be read :

• By pressing the + button continuously in the display the CH water pressure is shown.

• By pressing the - button continuously in the display the ionisation current is shown.

Daikin Europe NV 7

2.5.1 Frost protection

• The unit is fitted with frost protection in order to prevent it from

freezing. If the temperature of the heat exchanger drops too low, the pump will start running until the temperature of the heat exchanger

is sufficiently high. If the frost protection intervenes, code 7 will be displayed (heating up exchanger).

• If the installation (or a part thereof) can freeze, the coldest place

should be fitted with an (external) frost thermostat on the return pipe. This must be connected in accordance with the electrical diagram (see par. 10.2).

Note When the unit is switched off ( - on the service display), the unit frost protection will remain active, however a heating request from an (external) frost thermostat will be

ignored.

4.2 Installation space

The unit must be installed against a wall with sufficient load bearing capacity. In case of light wall constructions, there is a risk of resonance noises. Within 1 meter of the unit, there must be a earthed wall plug. In order to prevent the condense outlet from freezing, the unit must be installed in

a frost-free room. Preferably ensure there is a space of at least 2 cm next to the boiler. No free space is required due to danger of singeing.

4.2.1 Installing in kitchen cabinet

The unit can be placed between two kitchen cabinets, or inside a kitchen cabinet. Make sure there is sufficient ventilation at the bottom and the top.

If the unit is installed inside a cabinet, ventilation openings of at least 50 cm2 are required.

4.2.2 Removing cover plate and front panel

For various activities on the unit, the cover plate and front panel have to be removed from the unit, if they were installed. Do this as follows:

• If you are using the cover plate (A), remove it to the front.

• Unscrew both screws (1) behind the display window.

• Pull the bottom of the front panel (2) forwards.

Danger: risk of burning

In case of high leaving water set ponts for space heating (eighter a high fixed set point or a high weather-dependent set point at low ambient temperatures), the heat exchanger of the boiler can be very hot, for example 70°C.

Beware that in case of a tapping demand, the water can initially have a higher water temperature than requested.

In this case, it is recommended to install a thermostatic valve to prevent scalding. This can be done according to the schematics below.

a=boiler, b=DHW from boiler, c= cold water inlet,

d=shower, e=thermostatic valve (field supply)

Daikin Europe NV 13

3. Check the unit for any damage: immediately report damages to the supplier.

4. Install the suspension strip.

5. Check whether the compression rings are positioned straight in the couplings of the assembly bracket.

6. Position the unit: slide it from top to bottom over the suspension strip (B). Make sure the pipes slide into the compression fittings simultaneously.

7. Tighten the compression fittings onto the assembly bracket. The nipples and pipes must not rotate with it!

8. Open the display valve and loosen the two screws on the left and right of the display, and remove the front panel.

9. Assemble the flexible tube (D) onto the outlet of the siphon. Fill the siphon with water, and slide it as far as possible on top of the condense output connector (E) under the unit.

10. Seal flexible tube (D) of the siphon, if possible together with the overflow pipe of the inlet combination and the overflow valve, to the sewage via open connection (F).

Please note: When installing the boiler in combination with a cover plate, the siphon will extend underneath the cover plate.

Daikin Europe NV 15

5 CONNECTING

If an underfloor heating system is not hydraulically neutral, the underfloor heating pump may generate unwanted circulation over the boiler. For a good functioning of the domestic hot water provision, unwanted circulation over the boiler must be prevented.

Connect an underfloor heating system indirectly hydraulically neutrally or provide the CH installation with a two-way valve set 230 V ~ (E). If the underfloor heating pump absorbs heat via the return of the boiler, unwanted circulation can be prevented by means of a check valve (D).

5.1 Connecting CH installation

1. Rinse the CH installation carefully.

2. Fit the supply pipe (A) and return pipe (B) to the connection set.

3. All pipes must be assembled with no electrical current, in order to prevent shocks from the pipes.

4. Existing connections may not be rotated, in order to prevent leakages.

The CH installation must be fitted with:

• A filling/draining tap (A) in the return pipe, immediately underneath the unit.

• A draining tap at the lowest point of the installation.

• An overflow valve (B) of 3 bar in the input pipe at a distance of no more than 500 mm

from the unit. Between the unit and the overflow valve there may be no valve or constriction.

• An expansion vessel in the return pipe (in the B-pack or in the installation).

• A check valve, if there are pipes running up, within close distance of the unit. This

prevents a thermo siphon effect from occurring during tap water operation (a non spring-operated return valve, must be assembled vertically).

5.1.1 Thermostatic radiator taps

If all radiators are fitted with thermostatic or cable radiator taps, a minimum water circulation must be safeguarded. See par. 7.4.

5.1.2 Underfloor heating

Underfloor heating distributor with pump

Make sure there is a minimal water circulation. See par. 7.3.

Daikin Europe NV 16

Underfloor heating distributor without pump

Connect the underfloor heating system (D) and set the maximum CH supply temperature of the boiler to the design condition. Fit a clamp thermostat (A) onto the supply tube underneath the boiler. The clamp thermostat with blind cap must be set to a maximum supply temperature of 55°C.

Assemble the on/off room thermostat (B) and connect it in series with the clamp thermostat to connector X4 - 6/7 in the unit. See par. 10.1.

In this situation, the pump in the boiler is used to bridge the loss of pressure of the underfloor heating system. Using the loss of pressure graph par. 7.4, the maximum loss of pressure of the underfloor heating system can be determined.

Make sure there is a minimal water circulation. See par. 7.3. If required, install a bypass valve (C).

In case of an underfloor heating system without pump, we recommend changing the following parameter settings: par. o from 0 to 3. par. P from 5 to 2. Parameter 3 must also be set to its minimum level, or the transmission loss of the property.

Daikin Europe NV 17

5.1.3 Dividing CH installation in groups in case of additional heat

sources

Operating principle

If the room thermostat switches off the boiler because another heat source (wood heater, open fire etc.) heats the room, the other rooms may cool down. This can be resolved by splitting the CH installation into two zones. The zone with the external heat source (Z2) can be shut off from the main circuit by means of an electrical shut-off valve. Both zones are fitted with their own room thermostat.

Please note: "external heat source" regulation may only be applied if no extra external boiler has to be heated up (installation type 1).

Installation instructions

1. Install the valve in accordance with the connection diagram.

2. Connect the room thermostat of zone 1 to X4 – 6/7.

3. Connect the room thermostat of zone 2 to X4 – 11/12.

4. Change parameter A (see Parameter settings via the service code par. 7.2).

Please note: The room thermostat in zone 1 MUST be an on/off thermostat. The room thermostat in zone 2 may be an OpenTherm thermostat or an on/off thermostat.

5.2 Connecting DHW installation

1. Rinse the installation carefully.

2. If required, assemble an inlet combination.

3. Assemble the cold (D) and warm water pipe (C) to the connection set.

Comments

• If the unit is only used for warm water supply, the heating function can be

switched off using the service code on the operating panel. The CH installation does not need to be connected or filled.

• If the unit is switched off during winter, and is disconnected from the electricity

supply, the sanitary water must be drained in order to prevent freezing. To do so, disconnect the tap water connections underneath the unit.

In case of old installations or domestic hot water circuits which can contain small particles, install a filter in the domestic hot water circuit. This pollution could cause a fault during domestic hot water operation.
