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 settings with weather sensor
and room panel settings
Set parameter Weather mixer control. In
position off. Adjust weather curve according
to point 8.19. Room panel automatically
moves the heating curve depending on
preset room temperature. The controller
relates adjustements to 20ºC, i.e. for preset
room temperature = 22ºC the controller will
move heating curve by 2ºC, for preset room
temperature = 18ºC the controller will move
heating curve by -2ºC. In some cases
described in point 8.19 it can be necessary to
adjust heating curve movement.
In this configuration room thermostat 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 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
room panel) = 22ºC. Measured temperature
in room (using room panel) = 20ºC. Room
temperature factor = 15
Preset mixer temperature will be increased
by (22ºC – 20ºC) x 15/10 = 3ºC. Correct
value of parameter must be found room
temperature factor. The bigger value of
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.
8.19 Weather control
To control the boiler temperature from the
outside temperature, must be weather
control activated. Weather control requires
connecting an outside (weather) temperature
sensor. Weather sensor support should be
enabled in accordance with point 12.7
Depending on measured outside
temperature, automatically controlled can be
either preset boiler temperature and mixer
cycles temperatures. By correct adjustment
of heating curve temperature of heating
circuits is counted automatically depending
on value of external temperature. Thanks to
that by choosing proper heating curve for
given building, room temperature remains
approximately the same – no matter what
outside temperature. Attention: in the
process of experimental adjustement of
proper heating curve it is necessary to
exlude influence of room thermostat on
controller work (irrespectively if room
thermostat is connected or not), by adjusting
parameter:
Service settings → Boiler settings →
Thermostat select on OFF.
In case of connected room panel set
additionally Room temp. factor = 0.
Guidelines for correct heating curve settings:
• Floor heating 0,2 -0,6
• Radiator heating 1,0 - 1,6
• Boiler 1,8 - 4
