In this configuration a thermostat can be
connected. It will level inaccuracy of the
heating curve adjustment 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 disconnecting thermostat connectors
preset mixer cycle temperature will be
reduced. By correct adjustment of this
reduction will stop temperature increase of
temperature in heated room.
Mixer with weather sensor and room panel
ecoSTER200 settings
Set the parameter
Mixer weather control in
position off.
Adjust weather curve according to the point
7.15
The ecoSTER200 controller automatically
moves the heating curve depending on
preset room temperature. The controller
relates adjustments to 20
°C degrees, i.e. for
preset room temperature = 22 °C degrees
the controller will move heating curve by 2 °C
degrees, for preset room temperature =
18
°C degrees the controller will move
heating curve by -2 °C degrees. In some
cases described in the point 7.15 it can be
necessary
to adjust heating curve
movement.
In this configuration the 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 the 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 a room temperature
is done according to formula:
Correction = (preset room temperature
–
measured room temperature) x room
temperature factor / 10
Example.
Preset temperature in heating room (set in
the ecoSTER200) = 22
°C degrees. Measured
temperature in room (using the ecoSTER200)
= 20
°C degrees, room temperature factor =
15.
Preset mixer temperature will be increased
by (22
°C degrees – 20 °C degrees) x 15/10 =
3 °C degrees. Correct value of the parameter
room temperature factor should be adjusted.
Scope: 0…50. The bigger value of the factor
the bigger correction of preset boiler
temperature factor. When set on value “0”
preset mixer temperature is not corrected.
Attention: setting too high value of room
temperature factor may cause cyclic room
temperature fluctuations.
7.15 Weather control
Weather control may be activated for both,
boiler and mixer circuits. Once the heating
curve has been properly selected, preset
boiler or mixer temperature is automatically
computed on the basis of ambient
temperature. Owing to this feature, if the
heating curve is properly selected for the
given building, in-door temperature will
remain constant irrespective of the out-door
temperature. Therefore, proper selection of
heating curve is essential.
Note:
when identifying the heating curve -
eliminate influence of the room thermostat
on regulator operation (irrespective whether
the room thermostat is connected or not) by
setting the parameter:
For mixer circuit: MENU
→
Mixer
Settings
→
Room thermostat
→
Reduce preset mixer temperature to
thermostat
= 0.
For boiler circuit: MENU
→
Boiler
Settings
→
Room thermostat
→
Reduce preset mixer temperature to
thermostat
= 0.
In case of the connected ecoSTER200 room
control panel - additionally, set the
parameter: Room temperature coefficient =
0.
