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.
50ºC. 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. 5ºC. This value should
be
chosen experimentally. A room
thermostat can be a traditional one or a
room panel. After activating the thermostat,
mixer preset temperature will be reduced.
When this value is reduced correctly then
room temperature increase will be stopped.
Mixer settings with weather sensor,
without room panel.
Set parameter Mixer weather control in
position on. Adjust weather curve according
to point 8.18. Using parameter Curve shift
set required room temperature according to
formula: Required room temperature = 20°C
+ heating curve shift. In this configuration a
thermostat can be connected. It will level
inaccuracy of 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
plugs preset mixer cycle temperature will be
reduced. By correct adjustment of this
reduction will stop temperature increase of
temperature in heated room.
Mixer settings with weather sensor and
room panel.
Set parameter Mixer weather control. In
position off. Adjust weather curve according
to point 8.18. Room panel automatically
moves the heating curve depending on
preset room temperature. The controller
relates adjustments to 20
º
C, i.e. for preset
room temperature = 22
º
C the controller will
move heating curve by 2
º
C, for preset room
temperature = 18
º
C the controller will move
heating curve by -2
º
C. In some cases
described in point 8.18 it can be necessary to
adjust heating curve shift.
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.
8.18 Weather control
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 adjustment of
proper heating curve it is necessary to
temporarily exclude the influence of room
thermostat on the controller’s operation,
irrespectively
if room thermostat is
connected or not, by setting parameter:
