7.14 Disinfection of HUW container
The regulator has a function of automatic,
periodic heating of HUW container to 70 °C
to eliminate bacterial flora from the HUW
container.
Keep the tenants informed of
activating disinfection function as
there is a risk of being burnt with
hot utility water.
7.15 Mixer circle settings
Settings of first mixer circle are in the menu:

Mixer 1 settings
Settings for other mixers are in following
sections of the menu and are identical in
each cycle.
Mixer settings (without weather sensor) It
is required to set manually desired
temperature in mixer’s heating cycle using
parameter
Preset mixer temperature, e.g. 50
degrees C. Such should be a value to provide
required room temperature.
.
After connecting a room thermostat, value of
decline in preset mixer temperature from
thermostat should be set. (parameters
mixer
room thermostat e.g. 5 degrees C. This value
should be chosen experimentally. A room
thermostat can be a traditional one or a
room panel ecoSTER200. After activating the
thermostat, mixer preset temperature will be
reduced. When this value is reduced
correctly then room temperature increase
will be stopped.
Mixer with weather sensor setting
(without room panel ecoSTER200) Set
parameter
mixer weather control in position
on. Adjust weather curve according to point
8.16
Using parameter
paralel curve movement set
required room temperature according to
formula:
Required room temperature = 20°C +
heating curve paralel movement.
Example.
To reach room temperature 25°C value of
heating curve movement must be set for
5°C. To reach room temperature 18°C value
of heating curve paralel movement must be
set for -2°C.
In this configuration a thermostat can be
connected. It will level inaccuracy of heating
curve adjustement in case when its value will
be too big. In such case value of decrease of
preset mixer room temperature from
thermostat should be set i.e. for 2°C
. After
discontecting thermostat plugs preset mixer
cycle temperature will be reduced. By correct
adjustement of this reduction will stop
temperature increase of temperature in
heated room.
Mixer with weather sensor and room
panel ecoSTER200 settings
Set parameter Mixer weather control . In
position off.
Adjust weather curve according to point 8.16
Controller ecoSTER200 automatically moves
the heating curve depending on preset room
temperature.
The controller relates
adjustements to 20 degrees C, i.e. for preset
room temperature = 22 degrees C the
controller will move heating curve by 2
degrees C, for preset room temperature = 18
degrees C the controller will move heating
curve by -2 degrees C. In some cases
described in point 8.16 it can be necessary to
adjust heating curve movement.
In this configuration room thermostat
ecoSTER is able to:
reduce temperature of heating cycle by a
constant value, when preset temperature in
a room will be reached. Similarly like it was
described
in previous point (not
recommended), or
automatically, constantly correct heating
cycle temperature.
It is not recommended to use both these
possibilities at the same time.
Automatic correction of room temperaturę is
done according to formula:
Correction = (preset room temperature –
measured room temperature) x room
temperature factor / 10
