2.0 Safety notes
Instructions
This operating manual should be read carefully before installation and
start-up of the substation. The manufacturer accepts no liability for
damage or faults that result from non-compliance with the operating
manual.
Please read and follow all the instructions carefully to prevent acci-
dents, injury and damage to property. The risk of persons being injured
and equipment damaged increases considerably if the recommended
permissible operating parameters are exceeded.
Installation, assembly work, first start-up and maintenance work may
be carried out only by qualified and authorized personnel in compli-
ance with the safety regulations (both heating and electrical work).
Energy source
The substation is designed for district heating as the primary source
of energy. However, also other energy sources can be used where the
operating conditions allow it and always are comparable to district
heating.
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.
Connect the substation to the house installation in a frost-free room,
where the temperature does not exceed 50 °C and the humidity does
not exceed 60%. Do not cover or wall up the substation or in any other
way block the entrance to the station.
Choice of material
Choice of materials always in compliance with local legislation.
Corrosion protection
The maximum chloride compounds of the flow medium should not
be higher than 300 mg/l. The risk of equipment corrosion increases
considerably if the recommended permissible chloride compounds
are exceeded.
Safety valve(s)
We recommend mounting of safety valve(s), however, always in com-
pliance with local regulations.
Sound level.
≤ 55 dB.
Connection
The substation must be equipped with features that ensure that
the substation can be separated from all energy sources (also
power supply).
Warning of hot surfaces
Parts of the substation may become hot and hot surfaces can
cause serious burns. Please be extremely cautious in close prox-
imi-ty to the substation.
Warning of high pressure and high temperature
The stations work at a maximum supply temperature from the
district heating network of 120°C and the stations work with a op-
erating pressure of 16 bar, which may put the user at risk of burns
from touching the surface or from the emissions of hot media
(water/steam). The risk of persons being injured and equipment
damaged increases considerably if the recommended permissible
operating parameters are exceeded.
Emergency
In case of danger or accidents - fire, leaks or other dangerous cir-
cumstances - interrupt all energy sources to the station if possible,
and seek expert help.
In case of discoloured or bad-smelling domestic hot water, close
all shut-off valves on the substation, inform the operating person-
nel and call for expert help immediately.
Warning of transport damage
Before substation installation, please make sure that the substa-
tion has not been damaged during transport. Always transport
the substation with the utmost care and caution.
IMPORTANT -Tightening of connections
Due to vibrations during transport all flange connections, screw
joints and electrical clamp and screw connections must be check-
ed and tightened before water is added to the system.
After water has been added to the system and the system has
been put into operation, re-tighten ALL connections.
(Do not overstrain! - See item 7.7)
3.0 Storage and Handling
If the substation is stored before installation, make sure that the place
is dry and heated.
(Humidity max. 60% and storage temperature 5-70 °C).
Do not stack the unit higher than factory shipped. Units that are
shipped in cardboard packaging are to be lifted by the carrying
handles of the packaging. Transport / removals over great distances
should be carried out on pallets.
During and after unpacking, the substation can be lifted by using
straps, fitted around the pipes or it can be lifted by hand in the
pipes Lifting in the pipes can cause leaks. ALWAYS re-tighten.
Handling
When working on the substation suitable safety shoes must be
worn.
4.0 Disposal
Dispose of packaging material in accordance with local regulations.
This product consists of materials, which must not be disposed of
together with domestic waste. Switch off the complete power sup-
ply and dismantle the product and sort the components in various
groups before disposal. Always observe the disposal rules of the local
legislation.

7.6 Variable connection possibilities
The substation offers variable connection possibilities, as connec-
tion of pipes can be established in the top or in the bottom of the
substation. Upon delivery the substation is prepared for connec-
tion in bottom of the substation.
For change of connection from bottom to top, demount plugs on
connection pipes in top of substation and ball valves on connec-
tion 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.
Please note that the air screw, which originally is mounted on the
heating supply pipe in top of substation must be relocated to the
highest point of the substation.
PLEASE NOTE that the 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.
7.7 Tightening of connections
Check and tighten all connections before adding water to the
system, as vibrations during transport may have caused leaks.
After having added water to the system, tighten all the connec-
tions before performing leak test. If the substation operates in ac-
cordance with the dimensioning basis, re-tighten the connections
and take the substation into continuous use.
Please note that the connections may be supplied with EPDM rub-
ber gaskets - in general connection sizes from ¾”to and incl. 1½”
for Kompakt H stations. Therefore take care not to overstrain the
union nuts, as this may result in leaks. The manufacturer accepts
no liability for leaks that result from overstrain of union nuts.
7.8 Connection of expansion vessel
The expansion vessel is not part of the delivery.
Connect expansion vessel to substation either in the top or in the
bottom of substation, - contrary to pipes connection, which can be
established both in the top or in the bottom of the substation.
Necessary assembly, start-up and maintenance work must be per-
formed by qualified and authorized personnel only, and always in
compliance with local regulations and this instruction manual.
The substation must be easily accessible, enabling maintenance
work without undue discomfort.
The substation is intended for wall mounting and the mounting
sheet on the back of the substation has got holes for screw instal-
lation.
Fix the substation to a solid wall, which has the necessary load-
bearing capacity, in a workmanlike manner with two strong bolts,
screws or expansion plugs.
All pipes and connections must be cleaned and rinsed before
start-up. After that the strainers should be cleaned.
A symbol for each of the different connections is placed on the
substation. Connect the substation to the household system
according to these symbols as well as the instructions in this
manual.

11.0 Description
12.0 Heating circuit
12.1 Temperature control
The temperature for the heating circuit is controlled by the
Danfoss ECL controller. The supply temperature is calculated by
the controller on basis of the outdoor temperature.
The factory-setting of the controller ensures that heating is auto-
matically switched off in the summer period.
In periods with higher heat demand the controller settings can be
changed in accordance with the enclosed producer instructions
for the mounted controller.
Please see enclosed user guide,
Installation & Maintenance
ECL Comfort 200/P30 (for control of the heating circuit)
ECL Comfort 300/C66 (for control of both heating and domestic
hot water circuit)
Substation for indirect heating for small properties and apartment
houses. With one heating circuit and connection for domestic hot
water cylinder. For wall-mounting.
The substations are available in two basic variants - one variant
with Danfoss ECL 200 for control of the heating circuits and one
variant with Danfoss ECL 300 for control of the heating circuits and
the domestic hot water circuit.
The temperature for the heating circuit is controlled by the
Danfoss ECL controller in combination with an electronic actuator.
The supply temperature is calculated by the controller on basis of
the outdoor temperature.
For variants with Danfoss ECL 300 the domestic hot water tem-
perature is also controlled by an electrical actuator in combina-
tion with the electronic controller, incl. of an immersion sensor for
mounting in the DHW cylinder.
Please note:
Your substation may look different than the substation shown, as
variants with other components may be supplied.
Instructions for the fitted components will always be supplied to-
gether with the substation.

12.3 Heating circuit, temperature control H 328/35/42 ECL 300/C66
The H 328/H 335/H 342 substations are supplied with a 2-way
valve VS2 or VM2 and an electrical actuator AMV 10 or 20, which in
combination with the ECL controller controls the heating circuit.
The controller closes when set max. flow is exceeded.
A built-in differential pressure controller AVP-F protects the actua-
tor from too high differential pressure (see item 12.3.1).
The electrical actuator has undergone a functional test from fac-
tory. In case of operating disturbances the actuator can be closed
manually.
Please see enclosed instructions,
Electrical actuator AMV
2-vay valve
2-way valve
Manual override (AMV)
12.3.1 Differential pressure controller
The self-acting differential pressure controller AVP-F reduces the
fluctuating pressure in the district heating network to a small
and invariable operating pressure in the substation and thereby
ensures the best possible operating conditions.
The control valve opens on falling differential pressure to main-
tain constant differential pressure, and closes on rising differential
pressure.
The differential pressure controller is preset from factory and
should not be adjusted afterwards.

The KompaktHsubstationscomestandardwithWilocirculation pumps.
Alternatively Grundfos pumps may be used. The WiloWilo installation
and operating instructions will in such cases be replaced by Grundfos
installation and operating instructions.
Substation start-up / pump
Do not start up the pump until the system has been filled with the
flow media and vented.
On traditional heating systems the selector switch (the red button)
must be turned left for selection of constant pump operating mode.
It is recommended to set the pump at highest speed of rotation be-
fore start-up. Then set the pump at lowest possible speed of rotation,
in due consideration of the electricity consumption and the heating
comfort. (The factory setting of the selector switch, “the red button”
does not comply with the flow rate required for the system)
Floor heating
Selectvariablepump controlmode forfloor heating.Turn the redbut-
ton to the right.
Setthe pumpatlowestpossiblespeed ofrotation,indueconsideration
of the electricity consumption and the heating comfort.
Summer operation
The circulation pump for heating is automatically switched off in pe-
riods without heat demand. To prevent the pump from blocking in
periods without heat demand, the controller automatically switches
on the pump for some minutes every third day. In this period the
circulation pump should be set at the highest speed of rotation.
The shut-off valve/summer valve Sin top of the station can be closed
during this period. It is recommendable to vent the system after the
summer period.

closed installation and operating instructions:

Installation and operation instructions

For systems with Grundfos circulation pumps please follow the en-
closed Grundfoss Installation and Operating Instructions for setting
of pump.
In general, Grundfos recommends:
• AUTOADAPT (factory setting)
(This control mode is suitable for most installation. During operation, the pump auto-
matically reduces the factory-set setpoint and adjusts it to the actual system characte-
ristic).
• Proportional-pressure control (systems with relatively large pressure losses).
• Constant-pressure control (systems with relatively small pressure losses).
• Automatic night-time duty
Please note that the system can not be vented through the pump.
