Daikin Altherma LAN adapter
4P463935-1E – 2018.10
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 the installer reference guide.
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).
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.
Smart Grid operation mode SG0
(X1A/1+2)
SG1
(X1A/3+4)
Normal operation/Free running
NO Smart Grid application
Open Open
Recommended ON
Energy buffering in the domestic
hot water tank and/or the room,
WITH power limitation.
Closed Open
Smart Grid operation mode SG0
(X1A/1+2)
SG1
(X1A/3+4)
Forced OFF
Deactivation of outdoor unit and
electrical heater operation in
case of high energy tariffs.
Open Closed
Forced ON
Energy buffering in the domestic
hot water tank and/or the room,
WITHOUT power limitation.
Closed Closed

5 Installation
5.1 Mounting the LAN 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.
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
holes in the rear
(c).
▪ The wiring for X1A and X4A
MUST be routed and inserted
from the bottom. The wiring for
X2A and X3A CAN be routed
and inserted from the bottom
(or from the rear).
▪ When routing and inserting
wiring from the bottom,
remove the required knockout
holes in the bottom of the
casing (b)
and replace them
with the grommets from the
accessory bag.
Wiring routed and inserted from
the rear ▪ ONLY for in‑wall wiring
entering the adapter from the
rear.
▪ The wiring for X2A and X3A
CAN be routed and inserted
from the rear (or from the
bottom). The wiring for X1A
and X4A CANNOT be routed
and inserted from the rear.
▪ It is NOT allowed to route
wiring from the bottom, clamp
it between the casing and the
wall, and let it enter via the
holes in the rear
(c).
