COMMISSIONING STARTUP GUIDE
ATTENTION
The Startup guide must always be run, as it is the only way
to address the connected heat pumps.
The control unit is equipped with a commissioning assistant. This
assistant will guide you through the most important settings of
the regulator during initial commissioning. The “GO” symbol in
the main menu ashes. Click on the symbol to launch the com-
missioning assistant. The symbol will disappear as soon as initi-
al commissioning is complete. For more information on the com-
missioning assistant, please refer to the corresponding sections in
this operating manual..

NOTICE
The heating phase until the compressor starts can take se-
veral hours when starting up air/water heat pumps for the
rst time.
NOTICE
In the case of LWD units the ow is monitored while the
pump is running. If the ow is not ok, the heat pump does
not start up and no error is displayed. To this end, check
the ASD input, if it is not set to ON the ow is too low..
page 12, “Query inputs“
STARTUP ASSISTANT PARAMETERS BACK
If your heat pump was commissioned by an authorised customer
service partner and the startup parameters have been stored, you
can use this menu item to restore these parameters.
This may be helpful if settings have been changed and let to a
system malfunction. Please Notice that all settings such as hea-
ting curves, system settings, set values will be reset to the values
applicable at commissioning.
This does not apply to the time switches.
You will be guided through the following menu items:
As soon as the conrmation prompt is pressed the addressing of
heat pump 2 begins.
The screen does not change until it has nished addressing heat pump 2
NOTICE
Do not press the conrmation prompt in the screen until
the LINBus connection to heat pump 1 has been plugged
into the control board.
As soon as the prompt is conrmed the system checks whether
the connection with both heat pumps can be established.
Following successful checking and connection to both heat pumps the Startup
guide continues with further input prompts, which concern the settings of your
system, for example, with.

SMART GRID
Use of the Smart Grid option depends on the unit type and soft-
ware version.
If you have any questions regarding the availability of the Smart
Grid functionality in your electricity tari, please contact your
electricity supply company
The function is connected via two contacts of the utility lock,
from which four possible operating states result.
.NOTICE
If utility lock is applied, the Smart Grid functional may not
be activated.
ADJUSTABLE UNDER SYSTEM SETTINGS:
Current operating state visible under Information->Inputs
Operating state 1 (1:0)
Corresponds to the current utility lock.
Operating state 2 (0:0) - deviation from standard control behavi-
our:
The heat pump operates exclusively within the range of the set-
point hysteresis (i.e. below the setpoint).
Heating: If the system temperature drops to below the lower hy-
steresis, the heat pump is switched on and heats the system up to
the setpoint. The upper hysteresis is ignored. The heat pump on-
ly heats until there is no longer any need to worry about possi-
ble comfort losses. Domestic water heating takes place as normal.
Operating state 3 (0:1) - corresponds to standard control behavi-
our:
The target temperature is the set setpoint temperature for hea-
ting and domestic hot water. These set temperatures are held ta-
king into account the respective hystereses.
Operating state 4 (1:1) - deviation from standard control behavi-
our:
The heat pump operates exclusively within the range of the set-
point + hysteresis (i.e. above the setpoint).
Heating: If the system temperature drops to the setpoint, the he-
at pump is switched on and heats the system up to the setpoint +
hysteresis points
DHW: The controller generates a positive hysteresis whose magni-
tude is equal to the lower hysteresis and regulates in this area (set
temperature + upper hysteresis).

HEAT QUANTITY
Many heat pump types are equipped with heat quantity recording
by pressure sensors in the cooling circuit of the heat pump. In the-
se heat pumps the heat quantity can be read out directly – for all
other units in the Luxtronik 2.0 series the external heat quantity
meter can be retrotted (accessory).
