▪ LED flashing: LAN adapter

performing a Smart Grid
compatibility check.

(a) This LED is ONLY active for BRP069A61 (present for BRP069A62, but ALWAYS

inactive).

2.1 Compatibility

Make sure the heat pump system is compatible for use with the LAN adapter (app
control and/or Smart Grid applications). For more information, see the installer
reference guide of the heat pump system.

2.2 System layout

Integrating the LAN adapter into the heat pump system allows for the following
applications:

▪ App control (only)

INFORMATION

▪ The DIP switch is used to configure the system. For more information, see

"7Configuration"[429].

▪ When the LAN adapter performs a Smart Grid compatibility check, LD4 flashes.

This is NOT erroneous behaviour. After a successful check, LD4 will either stay ON
or go OFF. When it keeps flashing for more than 30 minutes, the compatibility
check failed, and NO Smart Grid operation is possible.

2 | About the adapter

INFORMATION

▪ For an overview of the possible system layouts, see "2.2System layout"[46]. For

more information about the electrical wiring, see "4.2 Overview of electrical

connections"[415].

▪ The function of the router in the system depends on the system layout. In case of

app control (only), the router is a mandatory system component, required for the
communication between heat pump system and smartphone. In case of Smart
Grid application (only), the router is NOT a mandatory component, but only used
for configuration purposes. In case of app control + Smart Grid application, you
need the router both as a system component and for configuration purposes.

▪ The smartphone and Daikin Residential Controller app are used to perform a LAN

adapter software update (if required). Therefore, ALWAYS take a smartphone
plus app to the installation site, also when the adapter is only used for the Smart
Grid application.

▪ Some tools and components might already be available on site. Before going on

site, find out which components are already at hand, and which ones you need to
provide (e.g. router, electricity meter, …).

4 | Preparation

Connector X1A is for the connection of the LAN adapter to the digital outputs of a
solar inverter/energy management system, and allows for the integration of the
heat pump system in a Smart Grid application.

X1A/N+L supply a 230 V AC detection voltage to the input contact of X1A. The
230V AC detection voltage enables the detection of the state (open or close) of
the digital inputs and does NOT supply power to the rest of the LAN adapter PCB.

Make sure X1A/N+L are protected by a fast acting circuit breaker (rated current
100mA~6A, typeB).

The rest of the wiring to X1A differs depending on the digital outputs available on
the solar inverter/energy management system and/or on the Smart Grid operation
modes that you want the system to run in. For more information, see "8Smart Grid

application"[437].

5.1 Overview: Installation

The installation of the LAN adapter consists of the following stages:

1 Mounting the rear casing to the wall
2 Mounting the PCB to the rear casing
3 Connecting electrical wiring
4 Mounting the front casing to the rear casing

5.2 Mounting the adapter

5.2.1 About mounting the adapter

The LAN adapter is mounted to the wall by way of the mounting holes (a) in the
rear casing. Before mounting the rear casing to the wall, you have to remove some
knockout holes (b)(c), depending on how you want to route the wiring and insert it
into the adapter.

5 | Installation

You can route and insert the wiring from the bottom or from the rear. Respect the
following rules and restrictions:

Wiring Possibilities and restrictions

Wiring routed and inserted from the
bottom

▪ ONLY for surface wiring routed from

the bottom.

▪ When routing wiring from the

bottom, ALWAYS let it enter the
adapter via the holes in the bottom of
the casing (b). It is NOT allowed to
clamp this wiring between the casing
and the wall and let it enter via the

Daikin Altherma LAN adapter
4P464229-1C – 2019.11

When the LAN adapter is used for app control (only), there is hardly any
configuration required. After correct installation and system start-up, all system
components (LAN adapter, router, and Daikin Residential Controller app) should be
able to find each other automatically by way of their IP address.

If the system components fail to connect to each other automatically, you can
connect them to each other manually by making use of a fixed IP address. In this
case, provide LAN adapter, router, and Daikin Residential Controller app with the
same fixed IP address. For how to provide the LAN adapter with a fixed IP address,
see "7.8Network settings"[434].

When the LAN adapter is used for the Smart Grid application, configure the LAN
adapter on the dedicated configuration web interface.

INFORMATION

By default "DHCP active" is set to "Automatic" and IP settings are configured
automatically and dynamically by way of the DHCP protocol. When setting "DHCP
active" to "Manually", you bypass the DHCP protocol. Instead, define a static IP
address for the LAN adapter in the fields next to "Static IP address".

When you set a static IP address for the LAN adapter, you make access to the
configuration web interface via the URL (http://altherma.local) impossible.
Therefore, when setting a static IP address, note it down somewhere, this for easy
future access to the configuration web interface.

The DIP switch allows you to assign a custom static IP address to the LAN adapter.
This IP address is "169.254.10.10". When you choose to do this, you bypass any IP
settings made on the configuration web interface.

To assign the custom static IP address to the LAN adapter:

1 Turn OFF the power to the LAN adapter.

2 Set DIP switch 2 to "ON".

3 Turn ON the power.

7.9 Removal

NOTICE

8 Smart Grid application

INFORMATION

This information ONLY applies to LAN adapter BRP069A61.

INFORMATION

To use the LAN adapter for the Smart Grid application, it is required that DIP switch 1
is set to "OFF" (default the case). Alternatively, to disable the possibility of using the
LAN adapter for the Smart Grid application, it is possible to set DIP switch 1 to "ON".

NOTICE

Use appropriate tooling to set the DIP switches to another position. Beware of
electrostatic discharge.

The LAN adapter allows for the connection of the heat pump system to a solar
inverter/energy management system, and enables it to run in various Smart Grid
operation modes. In this way, all system components work together to limit the
injection of (self-generated) power into the grid, instead converting this power into
thermal energy by making use of the thermal storage capacity of the heat pump.
This is called "energy buffering".

8 | Smart Grid application

The system can buffer energy in the following ways:

▪ Heat up the domestic hot water tank

▪ Heat up the room

▪ Cool down the room

The Smart Grid application is controlled by the solar inverter/energy management
system, that monitors the grid, and sends commands to the LAN adapter. The
adapter is connected to the solar inverter/energy management system (digital
outputs) by way of connector X1A (digital inputs).

INFORMATION

For the system to run in all 4 possible Smart Grid operation modes, the solar
inverter/energy management system needs to have 2 digital outputs available. If only
1 output is available, then you can only connect to SG0, and the system can only run
in the "Normal operation/Free running" and "Recommended ON" operation modes.
For the system to run in "Forced OFF" and "Forced ON", a connection to SG1 is
required (for those operation modes, SG1 needs to get "closed").

INFORMATION

In case the system layout includes a controllable wall socket, and the solar inverter/
energy management system activates this socket, SG0 gets "closed" and the system
runs in the "Recommended ON" operation mode. If the solar inverter/energy
management system deactivates the socket, SG0 (and SG1) get "opened" and the
system runs in the "Normal operation/Free running" operation mode (due to the

Buffering in case [C-07] = 0 OR 1

When, on the user interface, [C-07] = 0 OR 1 (the unit control method is leaving
water temperature control OR external room thermostat control), then the system
can only buffer energy in the domestic hot water tank, and only in the following
two separate cases:

▪ Space heating/cooling operation is turned OFF

OR

Installer reference guide

8 | Smart Grid application

▪ During space heating operation:

- Outdoor temperature > space heating setting [4-02]

- Room frost protection is not active

▪ During space cooling operation:

- Outdoor temperature < space cooling setting [F-01]

INFORMATION

▪ The system will ONLY buffer energy when the indoor unit is in standby mode.

Normal operation (scheduled actions, etc.) has priority over energy buffering.

▪ On the configuration web interface, the buffering is default set to "domestic hot

water tank only".

▪ The maximum temperature during domestic hot water tank buffering is the

maximum tank temperature for the applicable tank type.

▪ The space heating/cooling setpoint during room buffering is the comfort setpoint

for the room.

▪ The system will ONLY buffer energy during space heating if the space heating

setpoint is lower than the heating comfort setpoint. The system will ONLY buffer
energy during space cooling if the space cooling setpoint is higher than the
cooling comfort setpoint.

8.1.2 Power limitation

In the "Recommended ON" operation mode, the power consumption of the heat
pump system is limited either statically or dynamically. In both cases, it is possible
to include the power consumption of the electrical heaters in the calculation
(default NOT the case).

IF THEN

Static power limitation

(Static power limitation)

Dynamic power limitation

(Pulse meter setting)

The power consumption of the indoor
unit is limited statically based on a fixed
value (default 1.5kW) that is set in the
configuration web interface. During
energy buffering, the power
consumption of the indoor unit will NOT
exceed this limit.

The value for this setting is only used if
the system does not include an
electricity meter (on the configuration
web interface: Pulse meter setting: "No
meter"). Otherwise, make use of
dynamic power limitation.

The power limitation is auto-adaptive,
and dynamically performed based on
the power injection into the grid,
measured by the electricity meter. To
minimise the power injection into the
grid, the indoor unit operates as much
as possible.

INFORMATION

▪ In the "Forced ON" operation mode, energy buffering happens WITHOUT power

limitation.

▪ To get the most out of the energy buffering it is recommended to make use of

dynamic power limitation by way of an electricity meter.

▪ The electrical heaters will ONLY operate when the power limitation is higher than

the power rating of the heaters.

▪ For ERLQ011~016 and EBLQ+EDLQ011~016CA(3)V3+W1 outdoor units, the

power limitation functionality is NOT available. When these outdoor units are
used in a Smart Grid system, they will operate without power limitation. Electrical
heater assistance, however, will be disabled.

WARNING

Make sure to connect the electricity meter in the correct direction, so that it
measures the total energy injected INTO the grid.

INFORMATION

▪ For dynamic power limitation to be possible, a single connection point to the grid

is required (one connection point for the photovoltaic system AND the domestic
appliances). To function properly, the Smart Grid algorithm requires the net sum
of generated AND consumed energy. The algorithm will NOT work when there
are separate meters for generated energy and consumed energy.

▪ Since dynamic power limitation is performed based on electricity meter input,

you do NOT have to set the power limitation value in the configuration web
interface.

8.2 Operation modes

8.2.1 "Normal operation/Free running" mode

In the "Normal operation"/"Free running" operation mode, the indoor unit
operates as normal, according to its owner's settings and schedules. No Smart Grid
functionalities are enabled.

8.2.2 "Recommended ON" mode

In the "Recommended ON" operation mode, the heat pump system makes use of
solar/grid power (when it is available, as measured by the solar inverter/energy
management system) to produce domestic hot water and/or heat up or cool down
the space. The amount of solar/grid power that is used for buffering depends on
the domestic hot water tank and/or the room temperature. To align solar/grid
capacity and the power consumption by the heat pump system, the power
consumption of the indoor unit is limited either statically (by a fixed value set in the
configuration web interface) or dynamically (auto-adaptively, as measured by the
electricity meter – if part of the system layout).

8.2.3 "Forced OFF" mode

BRP069A61+BRP069A62
Daikin Altherma LAN adapter
4P464229-1C – 2019.11

In the "Forced OFF" operation mode, the solar inverter/energy management
system trigger the system to deactivate the operation of the outdoor unit
compressor and the electrical heaters. This is especially useful in case of energy
management systems that react to high energy tariffs, or in case of grid overload

Installer reference guide

41

8 | Smart Grid application

8.2.4 "Forced ON" mode

(signaled by the energy distributor to the energy management system). Once
active, "Forced OFF" mode will cause the system to stop space heating/cooling, as
well as domestic hot water production.

INFORMATION

Once running in one of the Smart Grid operation modes, the system will keep
running in that mode until the input state of the LAN adapter is changed. Beware
that if the system runs in "Forced OFF" mode for a long time, comfort issues can
occur.

In the "Forced ON" operation mode, the heat pump system makes use of solar/grid
power (when it is available, as measured by the solar inverter/energy management
system) to produce domestic hot water and/or heat up or cool down the space.
The amount of solar/grid power that is used for buffering depends on the domestic
hot water tank and/or the room temperature. In contrast to the "Recommended
ON" operation mode, there is NO power limitation: the system selects the comfort
setpoint for space heating/cooling, and will heat up the domestic hot water tank to
the maximum temperature. The outdoor unit compressor and the electrical
heaters are not limited in their power consumption.

The "Forced ON" operation mode is particularly useful in case of energy
management systems that react to low energy tariffs, in case of grid overload
(signaled by the energy distributor to the energy management system), or when
multiple houses are connected to the grid that are controlled simultaneously, this
to stabilise the grid.

INFORMATION

Once running in one of the Smart Grid operation modes, the system will keep
running in that mode until the input state of the LAN adapter is changed.

8.3 System requirements

In the rare case that the Daikin Residential Controller app does not find the LAN
adapter automatically, connect router, LAN adapter, and app manually by way of a
fixed IP address.

1 In the router, check the IP address that is currently assigned to the LAN

adapter.

2 Access the configuration web interface with this IP address.

3 On the configuration web interface, set "DHCP active" to "Manually".

4 In the router, assign a static IP address to the LAN adapter.

9.3 Solving problems based on error codes

9.3.1 Error codes of the indoor unit

5 On the configuration web interface, in the fields next to "Static IP address", set

the same static IP address.

6 In the Daikin Residential Controller app (Settings menu), assign the same IP

address to the LAN adapter.

7 Reset the power to the LAN adapter.

Result: Router, LAN adapter, and Daikin Residential Controller app share the same

fixed IP address and should be able to find each other.

If the indoor unit loses its connection with the LAN adapter, the following error
code appears on the user interface:

Error code Detailed error code Description

U8 01 Connection with adapter lost

9.3.2 Error codes of the adapter

LAN adapter errors are indicated by the status LEDs. There is a problem if one or
more status LEDs have the following behaviour:

LED Error behavior Description

Heartbeat LED NOT blinking No normal operation.

Network LED flashing Communication problem.

Indoor unit communication LED

Smart Grid LED flashing for
more than 30 minutes.

Please contact your dealer.

Try resetting the LAN adapter or contact
your dealer.

Check the network connection.

Communication problem with the
indoor unit.

Smart Grid compatibility problem.

Try resetting the LAN adapter or contact
your dealer.

INFORMATION

▪ The DIP switch is used to configure the system. For more information, see

"7Configuration"[429].

▪ When the LAN adapter performs a Smart Grid compatibility check, LD4 flashes.

This is NOT erroneous behaviour. After a successful check, LD4 will either stay ON
or go OFF. When it keeps flashing for more than 30 minutes, the compatibility
check failed, and NO Smart Grid operation is possible.
