7 Smart Grid application
INFORMATION
This information ONLY applies to LAN adapter
RBRP069A61.
The LAN adapter allows for the connection of the ROTEX system to
a photovoltaic system, minimising the power injection into the grid,
and maximising the self-consumption of the power generated by the
photovoltaics.
The Smart Grid application poses the following requirements to the
ROTEX system:
Item Requirement
LAN adapter software It is recommended to ALWAYS
keep the LAN adapter software
up-to-date.
Unit control method The indoor unit CANNOT be
controlled with the user interface
in LWT control ([C‑07]=0).
Power consumption control
settings
▪ Power consumption control
setting [A.6.3.1] (Mode) MUST
be set to
"Continuous" ([4‑08]=1).
▪ Power consumption control
setting [A.6.3.2] (Type) MUST
be set to "Power" ([4‑09]=1).
For the Smart Grid application, the LAN adapter PCB has 2 digital
inputs (SG0 (X1A/1+2) and SG1 (X1A/3+4)). These inputs need to
be controlled by an external controller, such as a solar inverter, or a
home energy management system. Depending on the state of the
inputs, you can make the system run in 4 Smart Grid operation
modes:
Smart Grid operation mode SG0 SG1
Normal operation (free mode) 0 0
Recommended ON 1 0
Forced OFF 0 1
Forced ON 1 1
7.1 "Normal operation" mode
In "Normal operation" mode, the indoor unit operates as normal,
according to its owner's settings and schedules. No Smart Grid
functionalities are enabled.
7.2 "Recommended ON" mode
In "Recommended ON" operation mode, the ROTEX system makes
use of photovoltaic energy for space heating/cooling and/or domestic
hot water production (i.e. energy buffering), minimising the power
injection into the grid. The amount of photovoltaic energy that is
used for buffering depends on the domestic hot water tank and/or
the room temperature. To align the photovoltaic capacity and the
power consumption by the ROTEX system, the power consumption
of the indoor unit is limited either statically or dynamically.
7.2.1 Energy buffering
The "Recommended ON" operation mode allows for buffering of
electrical energy into thermal energy. On the configuration web
interface, you can choose what to use as buffer: the domestic hot
water tank only, or the domestic hot water tank and the room.
To use the room as buffer
1Make the appropriate setting on the configuration web interface.
2Make sure user interface setting [C‑07] is set to 2:RTControl.
To use the domestic hot water tank as buffer
1Make the appropriate setting on the configuration web interface.
2Make sure a domestic hot water tank is part of the system.
3Make sure user interface setting [E‑05] is set to 1:DHW.
4Make sure user interface setting [E‑06] to 1:DHWtank.
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 domestic hot water setpoint 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.
7.2.2 Power limitation
In "Recommended ON" operation mode, the power consumption of
the ROTEX 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).

8 Troubleshooting
Installer reference guide
12
RBRP069A61
ROTEX LAN adapter
4P510034-1 – 2017.10
INFORMATION
▪ The electrical heaters will ONLY operate when the
power limitation is higher than the power rating of the
heaters.
▪ For RRLQ011~016 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.
Static power limitation
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.
Dynamic power limitation
To enable dynamic power limitation, the system requires an
electrical meter. In this case, the power limitation is auto-adaptive,
and dynamically performed based on the power injection into the
grid, measured by the electrical meter.
INFORMATION
▪ Make sure to connect the electrical meter in the correct
direction, so that it measures the total energy injected
INTO the grid.
▪ 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
electrical meter input, you do NOT have to set the
power limitation value in the configuration web
interface.
7.3 "Forced OFF" mode
In "Forced OFF" operation mode, the external controller can be set
to trigger the system to deactivate the operation of the outdoor unit
compressor and the electrical heaters. This is especially useful when
a controller is available that can react to high energy tariffs. Once
active, "Forced OFF" mode will cause the system to stop space
heating/cooling, as well as domestic hot water production.
INFORMATION
Once connected to run in one of the Smart Grid operation
modes, the system will keep running in that mode until the
input state is changed. Beware that if the system runs in
"Forced OFF" mode for a long time, comfort issues can
occur.
7.4 "Forced ON" mode
In "Forced ON" operation mode, there is NO power limitation. The
system selects the comfort setpoint for domestic hot water
production. The outdoor unit compressor and the electrical heaters
will consume as much energy as possible.
INFORMATION
Once connected to run in one of the Smart Grid operation
modes, the system will keep running in that mode until the
input state is changed.

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:
1Set DIP switch 4 to the "ON" position and reset the adapter by
turning the indoor unit OFF and ON again.
Result: The adapter now uses a fixed IP address
(169.254.10.10).
2Using an Ethernet cable, connect a computer directly to the
LAN adapter.
3In your browser, go to the fixed IP address.
Result: The configuration web interface opens.
4On the configuration web interface, go to Network settings, and
define a fixed IP address (Static IP address)(make sure
Manually is selected).
5Turn OFF the power to the unit.
6Set DIP switch 4 back to the "OFF" position.
7Turn ON the power to the unit.
Result: The adapter now uses a custom‑set fixed IP address.

contact your dealer.
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.
For a complete description of the status LEDs, check "2 About the
