Solving problems based on
symptoms
8.2.1
Symptom: Cannot access the web page
Possible causes
Corrective action
The LAN adapter is not powered
(heartbeat LED not blinking).
Make sure that the LAN adapter
is correctly connected to the
Daikin Altherma unit, and that the
power of all connected
equipment is turned ON.
The configuration web interface
is ONLY available for 2 hours
after every power reset. Its timer
can have run out.
Perform a power reset on the
LAN adapter.
The LAN adapter is NOT
connected to the network
(network connection LED NOT
blinking).
Connect the LAN adapter to a
router.
The LAN adapter is NOT
connected to the router or the
router does NOT support DHCP.
Connect the LAN adapter to a
router that supports DHCP.
The computer is NOT connected
to the same router as the LAN
adapter.
Connect the computer to the
same router as the LAN adapter.
INFORMATION
If none of the corrective actions work, try performing a
power reset of the total system.
8.2.2
Symptom: Router does not support DHCP
In the rare case that the router does NOT support DHCP, or this
functionality is disabled, you can use the following steps to assign a
fixed IP address to the router:
1
Set DIP switch 4 to the "ON" position and reset the adapter by
turning the Daikin Altherma unit OFF and ON again.
Result:
The adapter now uses a fixed IP address
(169.254.10.10).
2
Using an Ethernet cable, connect a computer directly to the
LAN adapter.
3
In your browser, go to the fixed IP address.
Result:
The configuration web interface opens.
4
On the configuration web interface, go to Network settings, and
define a fixed IP address (Static IP address)(make sure
Manually is selected).
5
Turn OFF the power to the unit.
6
Set DIP switch 4 back to the "OFF" position.
7
Turn ON the power to the unit.
Result:
The adapter now uses a custom‑set fixed IP address.

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