Daikin Altherma LAN adapter
4P464229-1B – 2018.10
4.2.1 Router
Make sure the LAN adapter can be connected via a LAN connection.
The minimum category for the Ethernet cable is Cat5e.
The function of the router in the system depends on the system
layout.
System layout Function
App control (only) The router is a mandatory
system component, required for
the communication between
Daikin Altherma system and
smartphone.
For more information, see
"2.2System layout"on page3.
Smart Grid application (only) The router is NOT a mandatory
system component, but only
used as a tool for configuration
purposes.
For more information, see
"7Configuration"on page14.
App control + Smart Grid
application
The router is both a mandatory
system component (app
control) and a tool for
configuration purposes (Smart
Grid application).
For more information, see
"2.2System layout"on page3
and "7Configuration"on
page14.
If the router is a system component, it can be integrated in the
system in the following ways:

INFORMATION
It is recommended to connect the LAN adapter to the
router directly. Depending on the wireless bridge or power
line adapter model, the system might not function properly.
4.2.2 Indoor unit
For power and communication with the indoor unit, the LAN adapter
is connected to the indoor unit's P1/P2 terminals via a 2‑wire cable.
There is NO separate power supply: the adapter gets its power from
the indoor unit's P1/P2 terminals.
4.2.3 Electricity meter
If the LAN adapter is connected to an electricity meter, make sure it
is an electrical pulse meter.
Requirements:
Item Specification
Type Pulse meter (5VDC pulse
detection)
Possible number of pulses ▪ 100pulse/kWh
▪ 1000pulse/kWh
Pulse duration Minimum On
time
10ms
Minimum OFF
time
100ms
Measurement type Depends on the installation:
▪ Single‑phase AC meter
▪ Three‑phase AC meter
(balanced loads)
▪ Three‑phase AC meter
(unbalanced loads)
INFORMATION
It is required that the electricity meter has a pulse output
that can measure the total energy injected INTO the grid.

4.2.4 Solar inverter/energy management
system
INFORMATION
Before installation, confirm that the solar inverter/energy
management system is equipped with the digital outputs
required to connect it to the LAN adapter. For more
information, see "8Smart Grid application"on page17.
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 Daikin Altherma 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).
