Instructions for installation and use Akva Lux II VX substations
4.0 Enduser instructions, General
Instructions
Please read these instructions carefully before installing and commissioning 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 physical injury and/or damage to property. Exceeding the
recommended operating parameters appreciably increases the risk
of personal injury and/or damage to property.
Installation, commissioning and maintenance must be carried out
by qualied and authorised personnel (both plumbing and electrical 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 VX, which
are district heating substations for indirect heating for single-family
houses, semi-detatched and terraced houses as well as ats. With
one or two heating circuits for radiator and/or oor heating and with
instantaneous water heater for domestic hot water heating. For wallmounting and with variable connection possibilities.
The HE supply temperature is controlled either by a self-acting thermostat T°C 200 or AVTB or by a Danfoss ECL controller in combination
with an electronic actuator. The ECL controller acts as the brain of
the heating system. It lets you easily control and optimize system
performance and operation.
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 unit.
Warnings about high pressure and high temperature
The maximum supply temperature in the district heating network can be up to 120°C (130° C*) and the operating pressure can
be up to 16 bar. This may result in a risk of scalding from touching
the substation and from outow of the medium (water/steam).
Exceeding 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 professional assistance without delay.
*
the substations can work temporarily at 130° C
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 dierence between the supply and
return temperature of the district heating water – has a signicant effect on the overall energy economy. Therefore, it is important to focus
on the supply and return temperature in the heating system.
The dierence should typically be 30–35°C in systems that operate
with radiators. In systems that feature oor heating, the dierence
is typically 5–10°C. In oor heating systems, the supply temperature
should not exceed 35°C.
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 situation, the district heating meter will register very modest consumption
as the volume of water is very small.
On substations with recirculation, the calorie meter registers the heat
loss in the recirculation pipe.
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.

Instructions for installation and use Akva Lux II VX substations
5.0 Enduser instructions, Initial adjustment and Setting
Domestic hot water control
Danfoss PTC2+P controller (Fig. 1) for domestic hot water. Set the DHW
temperature 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 must never exceed 55°C to prevent limescale
deposits building up in the water heater.
Fig. 1
Option: Alternatively the VX substations may be tted with a Danfoss
PM2+P controller (Fig. 2) 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.
Bypass or circulation thermostat
Thermostat (Fig. 3) that keeps the branch pipe warm in the summer
or regulates the circulation temperature if domestic hot water recirculation has been established in the hot water system (see pages 20-21
and page 37 for more information).
The thermostat should initially be set to position 3.
Heating circuit, Dierential Pressure Controller
The dierential pressure controller (Fig. 1) reduces the high, uctuating
pressure in the district heating network to a constant operating pressure.
The AVPL dierential 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 necessary to reset the dierential pressure controller
to a lower or higher operating pressure. We suggest that you contact
your local plumber for assistance.
The TD200 dierential pressure controller is preset from factory and
should not be adjusted afterwards.
Heating circuit, Temperature control
Thermostatic control
The supply temperature to the substation can be set by adjusting the thermostat TC (Fig. 5), which controls the temperature for the heating circuit.
The thermostat will be set by the installer in connection with the com
missioning, but it may be necessary to adjust it subsequently depending
on the outdoor temperature.
Approximate thermostat scale settings:
Pos. 2 = 30°C
3 = 40°C for range 25-70° C
4 = 50°C
5 = 60°C
or
Pos. 2 = 45°C
3 = 55°C for range 35-85° C
4 = 65°C
5 = 75°C
Please note that a label on the TC thermostat will indicate the temperature
range (g. 6).
The setting values may vary depending on the operating conditions. It is
important to set the supply temperature to the radiators as low as possible. 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.
ALWAYS refer to the instructions from the oor supplier.

Instructions for installation and use Akva Lux II VX substations
Alternatively the HE temperature is controlled by a self-acting temperature controller Danfoss AVTB (Fig. 5B). The controller has a control
valve, thermostatic actuator and handle for temperature setting. The
thermostat will be set by the installer in connection with the commissioning, but it may be necessary to adjust it subsequently depending
on the outdoor temperature.
Approximate thermostat scale settings:
1.0 = 35 °C
1.5 = 45 °C
2.0 = 55 °C
2.5 = 65 °C
3.0 = 75 °C
Other variations with other types of thermostatic valves for control
of the heating circuit may occur.
Electronic control
The temperature for the heating circuit can be controlled electronically by a Danfoss ECL 110, a Danfoss ECL 210 or a Danfoss ECL 310
controller (Fig. 6). The supply temperature ist calculated by the controller on basis of the outdoor temperature.
See the enclosed documentation for same.
Pump.
Akva Lux II VX substations are factory tted with a pump (Fig. 7). The
pump setting is established in connection with the commissioning. Generally speaking, 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.

Read and follow these instructions carefully to prevent the risk of physical 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
qualied 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 recommended chloride content is exceeded.
Safety valve(s)
Installation of safety valve(s) must always be in compliance with local
regulations.
Noise level.
≤ 55 dB.
PTC2+P controller for domestic hot water
The controller is preset from factory and sealed with a
red sticker. This sealing must not been broken.
The warranty becomes void if the sealing is broken.
Storage
Before installation, the units must be stored in a dry, heated (i.e. frostfree) 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.
Danfoss District Energy VI.GP.Q3 .02 DKDHR
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 equalizer connection to secure
against user contact with dangerous voltage, which may occur for
example between two piping systems. Potential equalization reduces
corrosion in heat exchangers, water heaters, district heating units and
plumbing installations. Equalization of potentials should be eected
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
substation.
Warning of high pressure and high temperature
The maximum supply temperature in the district heating network
can be up to 120°C (130°C*) and the operating pressure can be up
to 16 bar. This may result in a risk of scalding from touching the substation and from outow of the medium (water/steam). Exceeding
the substation design data and operating parameters for pressure
and temperature carries an appreciable risk of personal injury and/
or damage to property.
* the substation can work temporarily at130°C.
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 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.
NB! - Tightening of connections
Before mounting of the substation, ALL pipe connections MUST
be retightened, as vibrations during transport may have caused
leaks. Once the substation has been put into operation ALL pipe
connections MUST be pressure tested for leaks and retightened
once more if necessary.
DO NOT OVERTIGHTEN THE PIPE CONNECTIONS – see page 14,
“Test & connections”.
Handling
We recommend that you wear suitable safety footwear while
handling and installing the substation.

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 instructions in this manual.
If the system features DHW recirculation, a recirculation connection 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 page 20-21.
Commissioning
Please note that from factory the substation is prepared for
connection in bottom of the substation.
1. The ball valves, which are supplied loose with the substation, can
be mounted either on the top connections or bottom connections. For connection in top, demount the plugs from the top connections and mount them on the bottom connections.
(Please see instruction on page 14 for further information)
2. For connection in TOP for DCW and DHW please note that
this includes relocation of the built-in blind plates BEFORE
mounting the substation on the wall. (Please see instruction
on page 15 for further information).
3. If the household piping system features domestic hot water
recirculation, the substation must be connected to the recirculation system. See pages 20-21 for further information about
DHW recirculation.
4. The substation is prepared for wall mounting. Mount the substation on a solid wall using two sturdy bolts, screws, expansion bolts or similar.
5. Close all shut-o valves in the substation before connecting it/
them to the household piping.
6. Mount the district heating meter (see page 16).
7. IMPORTANT! Tighten all pipe connections, as they may have
loosened during transport and handling.
8. On systems that feature a safety valve, establish a drain connection in compliance with the applicable legislation.
9. Fill the heat exchanger / the system with water according
to the instructions on pages 18 and 19 until the manometer
shows a working pressure, which corresponds to the system

8.0 Installation instructions, general
The installation, connection and maintenance of the substation must
be performed by qualied and authorised personnel.
Installation must always be performed in accordance with the applicable legislation and in compliance with these instructions.
The substation must be installed so that it is freely accessible and can
be maintained without unnecessary disruption. Lift the substation
by its mounting plate and secure it to a solid wall using 2 sturdy
bolts, screws or expansion bolts positioned in the two keyholes in
the mounting plate.
Before commissioning, rinse all the pipes in the household piping
system thoroughly to remove any impurities, and check and clean
the dirt strainers in the substation.
Connect the substation to the household piping in accordance with
the labelling at the bottom and/or in accordance with the instructions in this manual.
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 overtightening or failure to retighten connections are not covered by
the warranty.
Variable connections possibilities
The Akva Lux II VX substations oer variable connection possibilities, as connections of pipes can be established in the top or in the
bottom of the substation. - Upon delivery the substation is prepared
for connction in bottom of the substation. Please note that the ball
valves are supplied loose and must be mounted on site.
For change of connection from bottom to top, demount plugs on
connection pipes in top of substation and ball valves on connection
pipes in bottom of substation, and mount plugs in connection pipes
in bottom of substation and ball valves on connection pipes in top
of substation.
These variable connection possibilities makes it possible to establish
some of the connections in the top and others in the bottom of the
substation. This may be desirable in some cases.

Control of heating circuit
The temperature for the heating circuit is controlled by a thermostatic valve T°C 200.
Approximate thermostat scale setting for range 25-70° C:
Pos. 2 = 30°C
3 = 40°C
4 = 50°C
5 = 60°C
6 = 70°C
Please note that the values are intended as a guide and may vary
according to the district heating operating conditions.
Approximate supply temperatures at:
10 °C outdoor temperature approx. 40°C
0 °C outdoor temperature approx. 55°C
-10 °C outdoor temperature approx. 65°C
Please note that a label on the thermostatic valve will indicate the
temperature range.
It is important to keep the supply temperature to the radiators as low
as possible (the temperature is indicated by thermometer mounted
in HE return). The room temperature is controlled by radiator thermostats.
Floor heating (substation with heat exchanger for oor heating)
It is important to keep the supply temperature to the oor heating
system as low as possible, approx. 30-35° (the temperature is indicated by thermometer mounted in HE return),
The T°C is typically set in pos. 2-2.5 (intended as a guide). The supply
temperature should not exceed 40°C
(ALWAYS refer to the instructions of the oor supplier)
Alternatively the HE temperature is controlled by a self-acting temperature controller Danfoss AVTB. The controller has a control valve,
thermostatic actuator and handle for temperature setting. The thermostatic actuator consists of a bellows, capillary tube and sensor.
The AVTB closes on rising temperature.
The thermostat will be set by the installer in connection with the commissioning, but it may be necessary to adjust it subsequently depending on the outdoor temperature.
Approximate thermostat scale settings:
1.0 = 35 °C
1.5 = 45 °C
2.0 = 55 °C
2.5 = 65 °C
3.0 = 75 °C
Other variations with other types of thermostatic valves for control

Control of heating circuit
The temperature for the heating circuit is controlled by a thermostatic valve T°C 200.
Approximate thermostat scale setting for temperature range 35-85°C:
Pos. 2 = 45°C
3 = 55°C
4 = 65°C
5 = 75°C
Please note that the values are intended as a guide and may vary
according to the district heating operating conditions.
It is important to keep the supply temperature to the radiators as low
as possible (the temperature is indicated by thermometer mounted
in HE return). The room temperature is controlled by radiator thermostats.
Please note that a label on the thermostatic valve will indicate the
temperature range.
Circulation pump, heating circuit

12.0 Domestic hot water (DHW)
Description
The domestic hot water is prepared in the heat exchanger based on
the ow principle and the temperature is controlled by a combined
hydraulic and thermostatic self-acting controller PTC2+P with integrated dierential pressure controller, which blocks the ow of
primary and secondary side ow through the heat exchanger immediately after completion of the tapping process.
12.1 Regulation of the domestic hot water temperature
PTC2 controller for domestic hot water (Fig. 1).
Danfoss PTC2 controller for domestic hot water. Adjust the hot water temperature 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
must never exceed 55°C to prevent limescale deposits building up
in the water heater.
Alternative controller PM2+P
As alternative the temperature can be controlled by a the pressure-controlled self-acting controller PM2+P with integrated dierential pressure
controller. 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 counterclockwise 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 pin must be positioned between the blue and red
dot, otherwise the controller will shut down.
12.2 Bypass or circulation thermostat (Fig. 2)
Bypass thermostat (default)
As a standard the substation is equipped with a bypass thermostat,
Danfoss FJVR, so that when water is tapped, the water heater
immediately starts to produce hot water. We recommend setting
of the thermostat in pos.3. If you have to wait a long time (i.e. more
than 20 sec.) for hot water, it may be necessary to set the thermostat
at a higher value.
1
Adjuster lever
Adjuster lever
2
Scale setting (indicative)
Pos. 2 = 30°C
3 = 40°C
4 = 45°C
If you want to avoid waiting time altogether, you will need to set up
domestic hot water recirculation to the tapping points.
Circulation thermostat / conversion to recirculation
If the household piping system features domestic hot water recirculation, the substation must be connected to the recirculation
system.
Conversion to recirculation requires only an additional circulation set.
(this is not part of the delivery and must be purchased as extra equipment, - see photo on page 21).
Connect the recirculation pipe from the xed household piping system
to the hexagon nipple, at the bottom of the substationtion (please
see pages 20 -21 for instructions about how to make recirculation
connection).
If a time-controlled pump is used, we recommend setting the circulation water temperature to approx. 35 °C.
Please note! If the circulation pump (outside the station) is
stopped for a protracted period, we recommend that the bypass
thermostat is shut o for the same period.

13.0 Maintenance
Maintenance work
Is only to be carried out by qualied and authorised personnel.
Inspection
The water heater should be checked regularly by authorised personnel.
Any necessary maintenance must be performed in accordance
with the instructions in this manual and other sets of instructions.
During service the dirt strainers are to be cleaned – including the lter
on the controller, all pipe connections must be tightened and the safety
valve must be function tested by turning the lever.
Rinsing/cleaning of plate heat exchanger
To clean the plate heat exchanger, rinse it by running clean water
through the exchanger at high speed and in the opposite direction to
the normal ow. This will remove any dirt deposits that may have built
up in the exchanger. If rinsing with clean water is not sucient, the
exchanger can also be cleane d by circulating a cleaning agent approved
by Danfoss (e.g. Kaloxi or Radiner Fl cleaning uid) through the
exchanger. Both these cleaning uids are environmentally friendly and
can be disposed o through the standard sewer system. After use of
a cleaning uid, the plate heat exchanger must be rinsed thoroughly
with clean water.
Acid cleaning of plate heat exchanger
Deposits of limesc ale may build up in plate heat exchangers for domestic
hot water on account of the large temperature uc tuations, and because
aerated water is used on the secondary side. If it becomes necessary
to clean the exchanger with acid, this can be done as shown on the
drawing to the right. Brazed plate heat exchangers can withstand
rinsing with a dilute acid solution - e.g. 5% formic, acetic or phosphoric
acid).
Measures after maintenance work
After maintenance work and before commissioning:
– Check that all screwed connections are tight.
– Check that all safet y features, covers, that were removed, have been
replaced properly.
– Clean the working area and remove any spilled materials.
– Clear all tools, materials and other equipment from the working area.
– Connect to energy supply and check for leaks.
– Vent the system.
– Carry out any necessary adjustment again.
– Make sure that all safety features on the device and the system work
properly.
Meter reading
The caretaker/owner must perform visual checking and reading of
the district heating meter at short, regular intervals. (The meter is
not a part of the delivery from Danfoss).
Service procedures must only be performed by trained, authorised
personnel.
NB! Excessive consumption for whatever reason is not covered by
the Danfoss warranty.
Cooling / Return temperature reading
Cooling – i.e. the dierence between the supply and return temperature
of the district heating water – has a signicant eect on overall energy
economy. Therefore, it is important to focus on the supply and return
temperature in the heating system. The dierence should typically be
30–35°C. Please note that a low district heating return temperature is
directly related to the return temperature from the heating circuit and
the return temperature of the circulation water.
It is therefore important to focus on these return temperatures.
40
DKDHR VI.GP.Q3.02 Danfoss District Energy
Instructions for installation and use Akva Lux II VX substations
Cooling from the water heater alone:
During tapping, the level of cooling will typically be 30–35°C. When
hot water is not being tapped, it is completely normal for the return
temperature from the water heater to rise slightly. In this situation,
the district heating meter will register very modest consumption as
the volume of water is very small.
On water heaters with recirculation, the calorie meter registers the
heat loss in the circulation pipe.
13.1 Maintenance schedule (recommendations)
Interval Maintenance work Comments
Check all connections for leaks
Check that the safety valve on the cold water supply is
functioning correctly.
Check that all components are intact and functioning as
intended

Check the pipes and exchanger for signs of corrosion Visual check
Check that the temperature regulators are set in accordance
with the instructions in this manual
Check the functions of all shut-o valves Check that the ball valves open and close as they should
Service and maintenance procedures must only be performed by
trained, authorised personnel.
Please note that after dismantling, the gaskets MUST be replaced.
Once the system has been lled with water, retighten 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 may feature EPDM gaskets! Therefore,
it is important that you DO NOT OVERTIGHTEN the pipe
connections. Over-tightening may result in leaks. Leaks caused by
over-tightening or failure to retighten connections are not covered
by the warranty.
If you identify a leak, replace the gaskets and retighten the pipe connections
Check the functionality by turning the lever on the safety valves
In the event of irregularities, lack of functionality or visible faults and
defects in a component, replace the component in questionn
Visual check. Check whether it is possible to disconnect the current to the
substation.

16.0 Commissioning Certicate
Commissioning certicate
The substation is the direct link between the district heating supply network and the household piping system. All supply pipes and the
pipes in the household piping system must be checked and rinsed before commissioning. Once the system has been lled with water, all
pipe connections must be retightened before performing pressure test for leaks. The dirt strainers must be cleaned and the substation
must be adjusted in accordance with the instructions in this manual.
It is important to comply with all technical regulations and the applicable legislation in every respect.
Installation and commissioning must only be performed by trained, authorised personnel.
The substation is checked in the factory for leaks before delivery. Leaks are however possible due to vibrations caused by transport, handling and heating of the system and therefore it is important to check all connections and to retighten if necessarys before commissioning.
Please note that the connections may feature EPDM gaskets! Therefore it is important that you DO NOT OVER-TIGHTEN the connections.
Over-tightening may result in leaks. Leaks caused by overtightening or failure to retighten connections are not covered by the warranty.
