General PLEASE NOTE, that other variants may be supplied.
The control function, however, is basically as described below, and the control of the substation
should be done in accordance with the enclosed producer instructions for the mounted controller.
Description
Heating circuit
Temperature control
District heating substation for direct heating with
mixing loop for single-family, semi-detached and
terraced houses as well as ats. With one heating
circuit and with connection pipes for cylinder on
primary side. Designed for wall-mounting.
The heating temperature is controlled by an electronic temperature controller Danfoss ECL with
an outdoor temperature sensor.
The substation is supplied with mixing ciruit and
is thereby especially suitable for systems with
oor heating. The task of the mixing circuit is to
ensure a correct supply temperature for the heating circuit (to protect the heating circuit against
too high temperatures) and to ensure, that the
return water is cooled down to the required
temperature, before it ows back to the district
heating plant. The mixing circuit temperature is
controlled by an electronic temperature controller Danfoss ECL.
The temperature for the heating circuit is controlled
electronically by the Danfoss ECL controller. The supply
temperature ist calculated by the controller on basis of
the outdoor temperature.
The ECL Comfort 210 controller is loaded with a selected
application by means of an ECL Application Key (Plug&-Play). The Application Key contains information about
application, languages and factory settings.
From factory the VX Solo II H2WP is loaded with Application 1d. Other applications can, however, be loaded by
means of the ECL Application Key, and it is possible to
update the controller with new application software.
The controller is factory preset to turn o the heating
automatically in the summer period.
The controller settings can be changed in accordance with the enclosed producer instructions for the
mounted controller.
See ECL Application Key Box with ECL Comfort
210/310 user guide and mounting guide, for further
information.
Please see enclosed user guide,
2-way valve + electrical actuator.
The S-Solo HWP is supplied with a 2-way valve VS
2, which in combination with an electrical actuator Danfoss AMV 150 controls the heating circuit.
The electrical actuator is preset from factory. In
case of operating disturbances the actuator can
be closed manually.

Instruction for use
Dierential pressure controller
AVPL
AVPL is a self-acting dierential pressure controller
for PN 16 with adjustable dierential pressure setting.
Der AVPL keeps a constant dierential pressure even
with a variable system resistance.
The AVPL can be set at any dierential pressure between 0,05 bar and 0,25 bar. The preset factory setting
of the controller is 0,1 bar.
To alter the dierential pressure, use an Allen Key NV 3.
1 full turn is equivalent to approx. 0.01 bar. The arrow
on the controller top shows that the setting of the differential pressure is increased when it is turned clockwise and reduced when turned counter-clockwise.
The controller settings can be changed in accordance
with the enclosed producer instructions.
Circulation pump Grundfos Pumpe ALPHA2 L
Substation start-up /pump
Do not start up the pump untill the system has
been lled with the ow media and vented. See
Grundfos instructions for the pump.
The pump is self-venting. It need not be vented
before start-up.
Air in the pump may cause noise, This noise ceases
after a few minu-tes running.
Please note, that the system cannot be vented
through the pump
Please note, that the pump must not run dry.
Pumpeneinstellung
GRUNDFOS ALPHA2 L has seven optional settings
which can be
selected with the push-button.
Enclosed photo shows the recommended and alternative pump settings for system types.
The pump is set at the factory to the “Higest proportional-pressure curve” (PP2). In this control
mode, the pump performance and consequently
the power consumption are adjusted according to
the heat demand in the system.
If the recommended pump setting does not give
the desired distribution of heat in the rooms of the
house, change the pump setting to the shown alternative.

Summer operation
Stationen with Danfoss T°C Thermostat
In the summer, you can stop the pump by switching it o at the mains. However, remember to start
the pump (briey) at least once a month during the
summer.
Systems with Danfoss ECL:
Outside the heating period, the pump will be disconnected automatically from the heating system.
During the summer period, the controller will start
the pump for a minute at least once very three days
to prevent the pump from blocking.
Start-up after summer operation - venting
Please note that it may be necessary to vent the
system again. To vent the system, use the air vent,
if any, in the substation, or the radiators or, if appropriate, the air valve at the highest point of the
system.

Maintenance
Meter reading
Cooling
Cleaning
Tightening
The substation requires little monitoring, apart
from routine checks and cleaning of strainers. To
ensure the best operating conditions regular inspection of the substation and a check of all relevant operating parameters are recommended,
for example in connection with meter reading.
Meter reading
We recommend that you read your meter regularly and that you write down the meter read.
Cooling / Return temperature reading
The cooling, i.e. the temperature dierence between district heating supply and district heating
return is of great importance for the total heat
economy. It is therefore very important to observe the supply and return temperatures.
Cleaning
All strainers should be checked and cleaned at
least once every year, typically in connection with
start-up of the heating system.
Tightening of connections
All threaded and anged connections should be
checked and tightened in connection with meter
reading. All threaded and anged connections
should be tightened regularly and especially in
connection with start-up after the summer period.
Venting
Strainer
Venting of system
Always vent the radiators and the substation before the heating season.
Strainer
Strainers should frequently be cleaned from
sediments by authorized personnel, according
to producer’s instructions and dependent on the
substation’s operating conditions.
