2 UNIT DESCRIPTION

2.1 General

The Daikin EKOMBG*AAV1 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 the combustion gas outlet of the EKOMBG*AAV1 can be connected
to the unit by two separate pipes, or by a concentric connection. 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 EKOMBG*AAV1 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 (G25) as a standard. On request, the unit can also
be provided for propane (G31).

2.2 Functioning

The Daikin EKOMBG*AAV1 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
and the modulating pump 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. The pump is only
operated during a heat request from the heating, depending on the requested power.

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

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.

0

Post-running CH

After the end of the CH-operation, the pump will post-run. 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.

will be displayed (heating up exchanger).

5

2

Selftest

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
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 down-time.

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

(code 5 ).

During CH operation, 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 or wireless
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.

of less than 40 degrees will be generated.

6

Domestic hot 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

(code 4 ), the controller will switch to domestic water operation (code
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 (it 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.

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.
In the settings "on" and "eco" , the unit meets the requirements of the Gaskeur
[Gas Inspection] CW standards.

2.4 PC Interface

The boiler controller is provided with an interface for a PC. A PC can communicate with
the CH boiler 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,

4.2 Installation spac e

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.

IMPORTANT

The unit must not be installed in a space where work is carried out
with aggressive or corrosive gases such as hairspray.

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 cm

2

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.

the inlet combination and the overflow valve, to the sewage via open connection
(F).

12. Assemble the air supply and the burning gas outlet (see par. 5.6).

13. Assemble the cover and tighten the two screws to the left and the right of the
display, and close the display cover.

4.3.4 Apply cover plate (optional)

Suspend the converted top edge of the cover plate from the washers underneath the
bottom of the unit, and slide the cover plate as far back as possible.

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.

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 thermosiphon 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. 7.3.

5.1.2 Underfloor heating

Underfloor heating with pump

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

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

Underfloor heating without pump

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

Fit the on/off room thermostat (B) and connect in a series with the clamp thermostat.
The boiler must be connected to X4 - 6/7.

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.
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, see par. 7.3.

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, the other
rooms may cool down.
This can be resolved by splitting the CH installation into two groups. The group with the
external heat source (Z2) can be shut off from the main circuit by means of an electrical
shut-off valve. Both groups are fitted with their own room thermostat.

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

Installation instructions

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

6. Connect the room thermostat of group 1 to op X4 – 6/7.

7. Connect the room thermostat of group 2 to op X4 – 11/12.

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

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

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 straight 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.
