13. Reaction speed
(factory setting 12)
Active only in the case of selection of equithermal regulation
with automatic correction according to the indoor
temperature! States how fast the requested temperatures
are achieved. Optional range
1 to 16 (by 1).
Turn the “ “ button to select the value and press ” “
button to confirm. Constant No. 14 automatically appears.
At the speed of reaction 1 the requested temperature is achieved
slightly, which prevents possibility of overusing, although the
requested temperature is achieved later. At the speed of reaction
16, in the case of the change of the requested temperature, there
is immediate heating up to the requested temperatures, but
overusing occurs.

11. Reg. period in minutes
(factory setting 10 min.)
It is selected according to the thermal inertia of the
object. The optimal setting is 10 to 15 min.
Optional range
5 min to 20 min (by 1min).
12. Reg. period in °C
(factory setting 2°C)
Only in the case of the option
PI regulation
(constant 8
= without equitherm).
The “zone of proportionality“ from
when the thermostat starts to restrict the CH temp.
(when the PI regulation starts). Optional range
1.5°C to 3.0°C (by 0.1°C).
The principle of PI regulation is based on comparing the
actual temperature of the room with the requested tem-
perature. This regulation depends solely on the indoor
thermostat sensor. Selection of constants 11,12:
when
setting the time section, it is necessary to ensure the thermal
inertia of the room. The optimal setting is 10-15 minutes.
If there are frequent thermal deviations in the room it is rec-
ommended to select a shorter time section. Zone of propor-
tionality states from which value the PI regulations will start.
14. Day of service
(factory setting 1.1.2029)
Setting the date for servicing the boiler. Notification for the
user regarding the maintenance of the boiler.
Turn the “ “ to set regulation interval and press ” “
button. Constant No. 12 or No. 13 automatically appears (at
the equitherm with automatic balancing).
The length of the interval in minutes influences the oscilla-
tion of the system. The lower this value, then the higher the
risk of oscillations.
If selecting the PI regulation (constant No. 8), it is necessary
to set the further parameter.
Turn the “ “ zone of the proportionality of PI regulation
and press the ” “ button. There is the automatic
appearance of constant No. 14.
In the case of selecting the PI regulation parameters,
orientate according to the PI regulation and follow
instructions shown at the graph.
Turn the “ “ button to consequently set day, month and
year for the revision and confirm each setting by the ” “ .
To speed-up the setting, press the button “

“, which
displays the actual date. The revision is cancelled by the change
of the date of revision. After setting constant No. 17 automati-
cally appears (or 15 in service mode).
At the stated date, the text “
revision of the boiler
is required
” is shown on the display.
15. Name of technical expert
Display of the name of the service technician. The name of
your service technician appears on the display. Active only
when in service mode.
16. Phone of technical expert
Display of the telephone number of the service technician.
The name of your service technician appears on the display.

Do not make any changes and you are in the introductory dis-
play, there is automatic termination of the service mode within
4 minutes.
10. Building insulation
The speed of the change of temperature in the room during
frequent deviations of outdoor temperature depends on the
construction and insulation of the building. With this constant, it
is possible to take into consideration the speed of the change of
temperature according to the type of heated building (only in the
case of equithermal regulation.
badly = uninsulated building,
responds quickly to a change in
the outdoor temperature
medium = insulated building,
responds slowly to a change in
the outdoor temperature
well = well insulated building,
responds slower to the
changes in the outdoor temperature
Turn the “ “ button to select the type of the building
according to the kind of insulation and press the ” “
button. There is the automatic appearance of constant
No. 14 (during manual correction) or No. 11 (during
automatic correction).
If stated, a new item appears in the information, for
