The regulator relates the setting to 20 °C,
e.g. for preset room temperature = 22 °C,
the regulator will translate the heating curve
by 2°C, for preset room temperature =
18 °C, the regulator will translate the heating
curve
by
-2 °C.
In some cases described in point 8.17,
it may be necessary to fine-tune the heating
curve translation.
In this setup, the ecoSTER200 room
thermostat can:
- decrease the heating cycle temperature by
a constant value when the preset room
temperature is reached. Analogously, as
specified in the previous point (not
recommended), or
- automatically, continuously correct the
heating cycle temperature.
It is not recommended to use both
options at the same time.
Automatic correction of room temperature is
carried out in accordance with the following
formula:
Correction = (Preset room temperature -
measured room temperature) x room
temperature coefficient /10
Example.
Preset temperature in the heated room (set
at ecoSTER200) = 22 °C. Temperature
measured in the room (by ecoSTER200) =
20 °C.
Room temp. coeff.
=
15.
Preset mixer temperature will be increased
by (22 °C - 20 °C) x 15/10 = 3 °C.
It is necessary to find appropriate value of
the
Room temp. coeff.
Range: 0…50. The
higher the coefficient, the greater the
correction of preset boiler temperature. If
the setting is “0”, the preset mixer
temperature is not corrected. Note: setting
a value of the room temperature coefficient
too high may cause cyclical fluctuations of
the room temperature!

Weather controlled operation
Depending on the temperature measured
outside the building, both preset boiler
temperature and temperatures of mixer
circuits can be controlled automatically. If
proper heating curve is selected, the
temperature of the circuits is calculated
automatically, depending on the outdoor
temperature. Thus, if the selected heating
curve is appropriate for the given building,
the room temperature stays more or less the
same, regardless of the temperature outside.
Note:
during trial and error selection of
appropriate heating curve, it is necessary to
exclude influence of the room thermostat on
regulator operation (regardless of whether
the room thermostat is connected or not), by
setting the parameter:
Mixer 1 settings > Mixer room therm.
to
“0”.
If a room panel ecoSTER200 is connected, it
is also necessary to set the parameter
Room
temp. coeff.
to “0”.
Guidelines for proper setting of the heating
curve:
floor heating
0,2 -0,6
radiator heating
1,0 - 1,6
boiler
1,8 - 4
Fig. 5 Heating curves.
Guidelines for selection of appropriate
heating curve:
- if the outdoor temperature drops, and the
room temperature increases, the selected
heating curve value is too high,
- if the outdoor temperature drops, and the
room temperature drops as well, the selected
heating curve value is too low,
- if during frosty weather the room
temperature is proper, but when it gets
warmer - it is too low, it is recommended to
increase the
Curve translation
and to select a
lower heating curve,
