Danfoss District Energy VI.HE.C3.02 DKDHR
Instructions for installation and use Akva Lux II S-F substations
4.0 Enduser instructions, General
Instructions
Please read these instructions carefully.
The manufacturer accepts no liability for loss or damage resulting
from failure to comply with these instructions. Read and follow these
instructions carefully to prevent the risk of physical injury and/or
damage to property. Exceeding the recommended operating pa-
rameters appreciably increases the risk of personal injury and/or
damage to property.
Installation, commissioning and maintenance must be carried out
by qualied and authorised personnel (both plumbing and electri-
cal work).
Once the station has been installed and is operating, there is nor-
mally no need to alter the settings or other functions. The district
heating substation is very reliable and easy to operate.
If necessary, you can change the temperature settings as described
on page 10. For more detailed information about the substation,
see the sections concerning installation and commissioning.
Description
These instructions apply to substation types Akva Lux II S-F, which are
district heating substations for direct heating for single-family, semi-
detached and terraced houses as well as ats. With one heating circuit
and instantaneous water heater for domestic hot water heating.
With mixing loop, which provides a suitable temperature level e.g.
for oor heating (protects the heating circuit against too high tem-
peratures) and ensures that return water is cooled to the required
temperature before it ows back to the DH plant.
Akva Lux II S-F substations are tted with a dierential pressure
controller that maintains a constant pressure in the heating circuit.
The supply temperature to the heating circuit is regulated using a
thermostat or an automatic controller. Akva Lux S-F substations are
also tted with a pump.
In rooms with oor heating, the temperature is regulated using the
oor heating thermostat for the room in question. In rooms with
radiators, the temperature is regulated using the radiator thermostats.
Alternatively, the heating circuits can be regulated using fully auto-
matic Danfoss ECL weather compensation equipment.
The Akva Lux II S-F variants are designed for wall mounting and are
available as built-in variant with a recess box or as wall-mounted
variant.
The Akva Lux II S-F, Types 144B2345, 144B2347, 144B2353 and
144B2112 are supplied with bypass thermostat mounted before
heat meter (bypass consumption is registered by the heat meter).
Akva Lux II S-F, type 144B2391 is supplied with bypass thermostat
mounted after heat meter (bypass consumption is not registered
by the heat meter).
Akva Lux II S-F, types 144B2347, 144B2353 and 144B2112 are wired
and tested in the factory. For type 144B2347 internal electrical com-
ponents are prewired into an electrical terminal box.
We recommend regular inspections of the substation - ideally in
connection with readings of the district heating meter.
Pay special attention to any leaks and an excessively high return
temperature in the district heating circuit (poor cooling of the district
heating water). Cooling – i.e. the dierence between the supply and
return temperature of the district heating water – has a signicant ef-
fect on the overall economy. Therefore, it is important to focus on the
supply and return temperature in the heating system.
Warning! Hot surfaces
Parts of the substation may be very hot and can cause burn in-
juries. Be very careful when you are in the immediate vicinity of
the unit.
Warnings about high pressure and high temperature
The maximum supply temperature in the district heating net-
work can be up to 90°C and the operating pressure can be up
to 10 bar. This may result in a risk of scalding from touching the
substation and from outow of the medium (water/steam). Ex-
ceeding the substation design data and operating parameters for
pressure and temperature carries an appreciable risk of personal
injury and/or damage to property.
Emergencies
In the event of re, leaks or other hazards, immediately shut o
all sources of energy to the substation, if possible, and call for
appropriate assistance.
If the domestic hot water is discoloured or malodorous, shut o
all ball valves on the substation notify all users and call for profes-
sional assistance without delay.
The dierence should typically be 30–35°C in systems that operate
with radiators. In systems that feature oor heating, the dierence
is typically 5–10°C. In these systems, it is important that the supply
temperature does not exceed 35°C.
Please note that a low district heating return temperature is directly
dependent on the return temperature from the heating/oor heating
circuit and the return temperature of the domestic hot water recircula-
tion (in systems with domestic hot water recirculation). It is therefore
important to focus on these return temperatures.
Cooling from the water heater alone:
During tapping, the level of cooling will typically be 30–35°C. When
domestic hot water is not being tapped, it is completely normal for the
return temperature from the water heater to rise slightly. In this situa-
tion, the district heating meter will register very modest consumption
as the volume of water is very small.
Irregularities
When reading the meters, check all joints and connections for leaks.
If you identify any irregularities/leaks, contact your professional
provider for assistance.
Check the troubleshooting section before contacting your
professional provider.

DKDHR VI.HE.C3.02 Danfoss District Energy
Instructions for installation and use Akva Lux II S-F substations
5.0 Enduser instructions, initial adjustment/setting
Domestic hot water control
Danfoss PTC2+P controller (Fig. 1) for domestic hot water. Set the DHW tem-
perature by moving the adjuster lever towards “+” (hotter) or “-” (colder). Start
by turning the lever clockwise – until it stops/until you cannot turn it any
further. Then turn the lever counter-clockwise until the temperature of the
tap water is approx. 48°C during normal tapping ow (7–8 litres per min.). The
temperature should never exceed 55°C to prevent limescale deposits building
up in the water heater.
Option: Alternatively the Akva Lux S-F substations may be tted with a Danfoss
PM2+P controller (Fig. 1b) for domestic hot water. Set the DHW temperature by
turning the adjuster lever towards red (hotter) or blue (colder). Start by turning
the lever clockwise – until the pin is opposite the blue dot. Then turn the lever
counter-clockwise until the temperature of the tap water is approx. 48°C during
normal tapping ow (7–8 litres per min.). The temperature must never exceed 55°C
to prevent limescale deposits building up in the water heater.
NB! The indicator of temperature setting must be positioned between the
blue and red dot, otherwise the controller will shut down.
Bypass or circulation thermostat
Thermostat (Fig. 2) that keeps the branch pipe warm in the summer or regu-
lates the circulation temperature if domestic hot water recirculation has been
established in the hot water system.
The thermostat should initially be set to position 3.
Heating circuit, Dierential Pressure Controller
The dierential pressure controller (Fig. 3) reduces the high, uctuating pres-
sure in the district heating network to a constant operating pressure. The dif-
ferential pressure controller is initially set by the plumber in connection with
the commissioning of the substation. If disruptions to the operation occur:
noise in the radiator thermostats or poor regulation capacity, it may be nec-
essary to reset the dierential pressure controller to a lower or higher operat-
ing pressure. We suggest that you contact your local plumber for assistance.
Heating circuit, Temperature control
Thermostatic control
The supply temperature to the heating circuit can be set by adjusting the
thermostat FTC (Fig. 4), which in combination with a 2-way valve type RA-C
controls the temperature for the heating circuit.
The thermostat will be set by the installer in connection with the commis-
sioning, but it may be necessary to adjust it subsequently depending on the
outdoor temperature.
Temperature range: 15-50 °C or 35-70 °C
The setting values may vary depending on the operating conditions.
It is important to set the supply temperature to the radiators as low as pos-
sible. Use the radiator thermostats to regulate the room temperature.
NB! For houses that are heated exclusively with oor heating.
The supply temperature should typically be set to approx. 30–35°C, which
corresponds to pos. 2–2.5 on the thermostat (guiding value). The supply tem-
perature must never exceed 40°C. (In addition, ALWAYS refer to the instructions
from the oor supplier).
Electronic control
Alternatively the temperature for the heating circuit can be controlled elec-
tronically by a Danfoss ECL 110 or 210 controller (Fig. 5). The supply tempera-
ture ist calculated by the controller on basis of the outdoor temperature. See
the enclosed documentation for same.
Pump.
Akva Lux II S-F substations are factory tted with a pump (Fig. 6). The pump
setting is established in connection with the commissioning. Generally speak-
ing, this setting is not to be altered. If it should nevertheless be necessary to
change the pump setting, see the section concerning pumps in the installation
and commissioning sections regarding the individual products.
In the summer, you can switch o the power to the pump at the mains if you
want to save electricity by not heating your home.
Start-up and venting – see the installation and commissioning sections, if
necessary.

Instructions for installation and use Akva Lux II S-F substations
6.0 Installation instructions, Safety and Handling
Instructions
Please read these instructions carefully before installing and comis-
sioning this substation. The manufacturer accepts no liability for loss or
damage resulting from failure to comply with these instructions for use.
Read and follow these instructions carefully to prevent the risk of physi-
cal injury and/or damage to peroperty. Exceeding the recommended
operating parameters considerably increases the risk of personal injury
and/or damage to property.
Installation, commissioning and maintenance must be carried out by
qualied and authorized personnel in compliance with the local safety
regulations.
Once the station has been installed and is operating, there is normally
no need to alter the settings or other functions. The district heating
substation is very reliable and easy to operate.
Energy source
The substation is primarily designed for connection to district heating.
Alternative energy sources can be used if the operating conditions are
equivalent to district heating at all times.
Application
The substation is designed only to operate with water or a water-glycol
mixture (up to 40%), and other heating media may not be used.
The substation is to be connected to the household piping in a frost-free
room, where the temperature does not exceed 50 °C and the relative
humidity is not higher than 80%. The substation must no be covered,
bricked in or otherwise cut o from access.
Choice of materials
Only use materials, that comply with local regulations.
Corrosion
The maximum chloride compounds of the medium must not be higher
than 300 mg/l. The risk of corrosion increases considerably if the recom-
mended chloride content is exceeded.
Safety valve(s)
Installation of safety valve(s) must always be in compliance with local
regulations.
Noise level.
≤ 55 dB.
Connection
It must be possible to cut o all energy sources to the unit - including
electrical connections - at all times.
Potential equalization/grounding
Potential equalization is an electrical equalizing connection to se-
cure against user contact with dangerous voltage, which may occur
for example between two piping systems. Potential equalization re-
duces corrosion in heat exchangers, water heaters, district heating
substations and plumbing installations. Equalization of potentials
should be eected according to local regulations.
Warning! Hot surfaces
Parts of the substation may be very hot and can cause burn injuries.
Be very careful when you are in the immediate vicinity of the substa-
tion.
Warning of high pressure and high temperature
The maximum supply temperature in the district heating network
can be up to 90°C and the operating pressure can be up to 10 bar.
This may result in a risk of scalding from touching the substation and
from outow of the medium (water/steam). Exceeding the substa-
tion design data and operating parameters for pressure and temper-
ature carries an appreciable risk of personal injury and/or damage
to property.
Emergencies
In the event of re, leaks or other hazards, immediately shut o all
sources of energy to the substation, if possible and call for appropri-
ate assistance. If the domestic hot water is discoloured or malodor-
ous, shut o all ball valves on the substation, notify all users and call
for professional assistance immediately.
Warning of damage during transport
On reception of the substation, and before installing it, check for any
evidence of damage during transport.
The substation must be handled and moved with the greatest care
and attention.
IMPORTANT - Tightening of connections
Before adding water to the system, ALL pipe connections MUST be
retightened, as vibrations during transport may have caused leaks.
Once the substation has been lled and the system has been put
into operation, ALL pipe connections MUST be tightened once more.
(Do not overtighten! - See page 14, Test and Connections)
Storage
Before installation, the units must be stored in a dry, heated (i.e. frost-
free) room.
(Relative humidity max. 80% and storage temperature 5-70 °C).
The units must not be stacked higher than the limit at the factory (max.
8 layers) Units supplied in cardboard packaging must be lifted using the
handles incorporated in the packaging. Units must be placed on pallets
for transport/moving across large distances.
As far as possible, do not lift the substation by the pipes. Lifting by the
pipes may cause leaks. REMEMBER to retighten.
Disposal
Dispose of the packaging in accordance with the local regulations for
disposal of used packaging materials.
The substation is made of materials that cannot be disposed of together
with household waste.
Close all energy sources and disconnect all connection pipes. Disconnect
and dismantle the product for disposal in accordance with the applicable
local regulations for the disposal of the individual components.
Handling
We recommend that you wear suitable safety footwear while
handling and installing the substation.

Instructions for installation and use Akva Lux II S-F substations
7.0 Installation instructions, GETTING STARTED
Connect the substation to the household piping in accordance with
the labelling at the bottom and/or in accordance with the instruc-
tions in this manual.
If the system features DHW recirculation, a recirculation connec-
tion must be established on the substation. The circulation set
is optional equipment, which must be ordered separately and
mounted on site.
We recommend establishing recirculation BEFORE mounting the
substation on the wall.
For instructions about recirculation connection, see pages 17 -25.
GETTING STARTED is a quick guide and some details in connection with
installation and commissioning may require additional information,
which can be found elsewhere in this instruction manual.
Commissioning:
Please note that the “getting started” quick guide presupposes
that shutt-o possibility is established to and from the substa-
tion. - We recommend mounting of ball valves.
Please note that ball valves are not part of the delivery for most
types of S-F substations and must be ordered separately.
1. If the household piping system features domestic hot water re-
circulation, the substation must be connected to the recircula-
tion system. See pages 17 -25 for further information.
2. The substation is prepared for wall mounting. Mount the sub-
station on a solid wall using two sturdy bolts, screws, expan-
sion bolts or similar.
3. Mount ball valves (not part of the delivery) on the substation
and make sure that they are closed, when connnecting them
to the household piping.
4. Mount the district heating meter (see page 14).
5. IMPORTANT! Tighten all pipe connections, as they may have
loosened during transport and handling.
6. On systems that feature a safety valve, establish a drain con-
nection in compliance with the applicable legislation.
7. Open the ball valve for the HE supply and return ow and ll
the system with water by carefully opening the ball valve for
the district heating supply ow and at the same time venting
the system.
Finally, open the ball valve for the district heating return ow.
8. Check the substation and the household piping thoroughly
for leaks.
9. Pressure test the entire system for leaks in accordance with
the applicable regulations.
10. Connect pump and automatic components, if any, to the elec-
tricity supply, but do not switch on the power.
11. Heat the system and vent the radiator circuit/heating side
thoroughly on the radiators and the air valve, if any.
12. For S-F stations, which include zone valve, remember to re-
move the red split on the position indicator of the zone valve.
13. Now switch on the pump and automatic components, if
any.
14. Finish by adjusting the substation in accordance with this
instruction manuals.
Heating and cooling of the system may cause leaks. There-
fore it may be necessary to retighten the connections in the
period after commissioning.

supply temperature to the heating circuit is regulated using a ther-
mostat (types 144B2345, 144B2347 and 144B2391) or an electronic
controller (types 144B2353 and 144B2112). Akva Lux S-F substations
are also tted with a pump.
In rooms with oor heating, the temperature is regulated using the
oor heating thermostat for the room in question. In rooms with
radiators, the temperature is regulated using the radiator thermostats.
Alternatively, the heating circuits can be regulated using fully auto-
matic Danfoss ECL weather compensation equipment.
The Akva Lux II S-F variants are designed for wall mounting and are
available as built-in variants with a recess box or as mount-on-wall
variants.
The Akva Lux II S-F, Types 144B2345, 144B2347, 144B2353 and
144B2112 are supplied with bypass thermostat mounted before
heat meter (bypass consumption is registered by the heat meter).
Akva Lux II S-F, type 144B2391 is supplied with bypass thermostat
mounted after heat meter (bypass consumption is not registered
by the heat meter).
Akva Lux II S-F, types 144B2347, 144B2353 and 144B2112 are wired
and tested in the factory. For type 144B2347 internal electrical com-
ponents are prewired into an electrical terminal box.

Test and connections
Before lling the system with water, retighten all the pipe connections
because vibrations and shocks during transport and handling may
have caused leaks. Once the system has been lled with water, tighten
all the pipe connections once more before performing pressure test
for leaks. After heating of the system, check all the connections and
retighten if necessary.
Please note that the connections feature EPDM rubber gaskets!
Therefore, it is important that you DO NOT OVERTIGHTEN the
union nuts. Over-tightening may result in leaks. Leaks caused by
over-tightening or failure to retighten connections are not covered
by the warranty.

Electrical junction box
The electrical junction box houses the internal electrical connections
of the substation and allows the wiring in the substation to interface
with the main power supply provided by a local utility.
For the Akv Lux II S-F with junction box, the pump and zone valve are
pre-wired to the junction box, and the junction box is also prepared
for connection of a room thermostat.
In case of oor heating a safety switch is also connected in the junction
box, securing that zone valve and pump will close in case of overheat-
ing.
See enclosed wiring diagram for more information.
Zone valve / thermal actuator TWA-V
The Akva Lux II S-F can be supplied with zone valve/thermal actuator
TWA-V, which enables connection to an electronic programmable
room thermostat.
The thermal actuator of the zone valve is switched on by an exter-
nal contact from the room thermostat, and starts to open or close
the valve. The actuating movement is achieved by means of an
electrically heated expansion element. When the heating current is
switched o, the actuator shuts or opens the valve.
The actuator is equipped with a visual position indicator to show
the open or closed position of the valve.
Electronic programmable room thermostat (option)
If the substation is connected to a room thermostat the tempera-
ture is controlled by the room thermostat and radiator thermostats.
Please note that the room thermostat keeps the temperature at a
constant level in the whole apartment according to the set room
parameters.
Consult additional maintenance instructions for room thermostat
for further information. It is recommended to avoid fully opened
thermostats on some radiators and fully shut-o on others. Higher
temperature at the top and lower temperature at the bottom part
of radiators means that the system operation is correct. To keep cor-
rect temperature and friendly microclimate for human beings in the
apartment, it is recommended to ensure regular airing in rooms.

Safety valve
As optional equipment the substation can be equipped with a safety
valve set with 60 mm ball valve, - total length 120 mm.
Please note that this is not part of the delivery and must be ordered
separately and mounted on site.
(Safety valve should always be mounted when establishing DHW-recirculation).
Always establish a blow-o pipe from the safety valve. The blow-o
pipe must be lead to a drain in accordance with applicable legislation.
See separate installation guide for mounting of safety valve set.
The safety valve set is prepared for mounting on at stations with and
without circulation set.
Photo 1 illustrates mounting of safety valve set on at station without
circulation set.
Photo 2 illustrates mounting of safety valve set on at station with
circulation set.
10.0 Installation instructions, recirculation connection
If the household piping system features domestic hot water
recirculation, the substation must be connected to the recirculation
system. The circulation set for recirculation connection is not standard
equipment. The set must be purchased as extra equipment.
We recommend establishing recirculation BEFORE mounting the
substation on the wall.
Connect the recirculation pipe from the xed household piping to
the hexagon nipple at the bottom of the substation, - see photo to
your right .
You must always t a pump and a non-return valve to the recir-
culation pipe, with ow direction towards the substation.
A safety valve must be mounted in the DCW inlet.
If a time-controlled pump is used, we recommend setting of the
circulation water temperature to approx. 35°C.
Please note that if the circulation pump (outside the substation) is
stopped for a protracted period, we recommend that the bypass
thermostat is shut o for the same period.
Please note that four circulation sets for recirculation connection are
available as optional equipment.
The four circulation sets and and control change possibilities from
bypass to DHW recirculation will be described thoroughly on pages
18 to 25.
