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 ecoSTER TOUCH) = 22°C. Temperature
measured in the room (by ecoSTER TOUCH)
= 20°C. Room temp. factor = 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. factor. 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!
8.18 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/ecoSTER
TOUCH is connected, it is also necessary to
set the parameter Room temp. factor 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
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 shift and to select a lower
heating curve,
- if during frosty weather the room
temperature is too low, and when it gets
warmer - it is too high, it is recommended to
decrease the Curve shift and to select a
higher heating curve.
Buildings with poor thermal insulation require
higher heating curves, whereas for buildings
which have good thermal insulation, the
heating curve can have lower value.
The regulator can increase or decrease the
preset temperature, calculated in accordance
with the heating curve, if it exceeds the
temperature range for the given circuit.
8.19 Night decrease settings description
Night time decrease for heating circuits,
HUW container and circulation pump.
Time periods allow setting temperature
reduction in given time period – i.e. at night
or when user leaves the heated room.
Thanks to it preset temperature can be
