6. Min. temp. heating watter
(factory setting 30°C)
States the lower limit of the requested temperature for
heating water calculated by the thermostat for when
the heating can start. This constant prevents
redundant activation of the boiler
.
Optional range from
5.0 °C to 50.0°C (by 1.0°C).
7. Max. temp. heating watter
(factory setting 70°C)
States the upper limit of the requested temperature of the heating
water calculated by the thermostat which the boiler must not
exceed. Difference between the minimum and ten maximum
temperature must be greater than 8°C.
Optional range from
13.0 °C to 85.0°C (by 1.0°C).
Turn the “ “ button to set the minumum temperature

8. Number heating curve
(factory setting “Room control”)
Selection of the type of regulation.
Room control = PI regulation (according to the
inside temperature).
The thermostat heats up
depending on the temperature in the reference room.
It is necessary to set constants 11 and 12!
1 - 60 = equithermal regulation,
number 1 to 60
corresponds to the requested heating curve (see below)
It is recommended to select equithermal regulation for large buildings where it is not possible to select a reference room. The principle of
equithermal regulation is optimising the temperature of the water for the heating system depending on the outdoor temperature.
The mentioned equithermal curves express this dependence (for a requested room temperature of20°C), according to which it is possible to select the
requested temperature of the water in the heating system. The thermostat calculates the temperature of heating water according to the selected
equithermal curve which is consequently sent to the boiler. Then the boiler regulates the temperature of heating water to the requested value.
It is necessary to select the slope of the curve according to the heating system to prevent permanent over or under heating of the building.
The selection of the correct curve for the stated system is a long-term issue and it is necessary to test the system at various outdoor temperatures! It is
recommended to modify the indoor temperature in the rooms, e.g. regulation by thermostat heads.
The water temperature in the heating system is
restricted by minimum and maximum limits which are set in constants No. 6 and 7! During this regulation, the outdoor sensor must always be
connected to the boiler!
Turn the “ “ button to select the type of regulation
and press the ” “ button to confirmation.
In the case of selection of equithermal regulation follow
the instructions under the graph with the heating
curves
.
If selecting a requested room temperature of other than
20 °C, the thermostat calculates the automatic shift of the
curve according to the following equation where the
coefficient is 1:
shift = (requested temper. - 20) * coefficient
Note.: the most frequently used curve under our conditions
is 9-11 for low-temperature systems and 15-17 for traditional
heating systems.
After selection of the optimal heating curve and the
confirmation, there is a shift to constant No. 9.
In the case of option PI regulation
constants No. 9, 10 are
skipped and constant No.11 is automatically displayed for
further setting of the Pl regulation.
9. Parallel displac. h.c.
0.5 to 10.0 =manual correction according to the
coefficient
, used if the temperature is not
according to your requirements (by 0.5).
In the case of this regulation, the heating curve is automatically corrected depending on the outdoor temperature, as well as
the actual temperature in the reference room where the thermostat is located.
This enables to achieve higher thermal comfort in
the heated area, optimal operation of the heating system and greater savings! During this regulation, the sensor must always be
connected to the boiler and
constant No. 9 must be set to „AUTO”
!
AUTO= automatic correction
, according to the
indoor temperature measured in the reference
room. It is possible to use this option after the
correctly selected equithermal curve!
Example
describes the option for equithermal curve No. 13
(pink) and the calculated correction with the coefficient 2.5
(for requested room temperatures of 24 °C and 16 °C). The
optimal setting of the system is achieved when the water tem-
perature of the heating system is regulated according to the
actual outdoor temperature.
In the case of setting the equithermal regulation, it is possible
to select manual correction of the shift of the curve or the
automatic correction according to the indoor temperature.
Turn the “ “ button to set the correction for the curve and
press the ” “ button to confirm.
In the case of
manual correction
set the shift coefficient
for the heating curve when at various requested tempera-
tures in the reference room, regulation of the heating water
will be reached according to the actual outdoor tempera-
ture (for the formula, see constant No. 8).
After setting and confirmation, there is the automatic
transfer to constant No. 10.
In the case of option
automatic correction according
to the indoor temperature, constants No. 10, 11 and
13 must be set.
