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 14, “Query inputs“
The selection possibility for the heat source for SWP:
NOTICE
For SWP it is necessary to select whether water or brine
is to be used as the heat source uid, otherwise the unit
doesn’t work. The set uid can be viewed under System
Settings and can be changed from Customer Service ac-
cess level. TWQ-Min can be changed using the customer
service access, if brine is selected. For Low pressure cut-o
value with water: 7 bar. For Low pressure cut-o value with
brine: 4 bar.
Brine
This setting must be selected if the heat pump is opera-
ted with a brine - water mixture. Whether probes or sur-
face collectors are used is irrelevant.
Water |/| Brine
This setting must be selected if the heat pump is opera-
ted with an intermediate heat exchanger, and water is
used as the heat source medium on the primary side and
a brine-water mixture is used on the secondary side.
Water |/| Water:
This setting must be selected if the heat pump is opera-
ted with an intermediate heat exchanger and water is

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).
