The minimum time of operation of the
boiler during hysteresis is set in minutes.
Selection is to be made according
to the type of the heating system used
(see the table)
5. SELECTION OF HYSTERESIS OR PI REGULATION
Set the
hysteresis
from
0.1°C to 1.5°C
with the
+/- T
buttons.
When hysteresis is selected, the constants (6, 7, 8), which are related to the setting of the parameters of PI regulation,
are skipped automatically.
When three horizontal dashes are selected using the
+/- T
buttons,
PI regulation
will be active.
6. TIME PERIOD OF PI REGULATION
Is to be selected within the range from
5 to 20 minutes
. The length of this period is given by the thermal lag of the
room.
The optimum setting is 10 to 15 minutes.
7. THE MINIMUM TIME OF OPERATION OF THE HEATING APPLIANCE DURING PI
REGULATION
This is to be selected within a range from 1 to 5 minutes.
The setting depends on the type of heating system
and is dependent on the selection of the time
period for PI regulation.
We recommend setting it according to the table.
8. ZONE OF PROPORTIONALITY DURING PI REGULATION
This information determines the value from which PI regulation will start
functioning. For example, the required temperature is 22.0°C, and the zone
of proportionality is 1.5°C. Up to a temperature of 20.5°C, the source will
give out maximum heat. After this value has been achieved, PI regulation
will start functioning.
The zone of PROPORTIONALITY can be set from
1.5 do 3.0°C
.
9. INDICATION THAT THE HEATING SYSTEM REQUIRES
MAINTENANCE
Set the date (day, month, year) when you want to be informed about the
necessity for routine servicing to be carried out on the heating source. On
the required day, the
Udr
symbol and
will appear on the LCD (erase the
date by entering a new one for the next maintenance session!).
11. SELECTION OF CONTROL VIA THE GSM MODULE
Via this constant, you can select the option of controlling the central unit via
the GSM module.
Options:
GSM: N
gsm module is not permitted; constants 12 and 13 are skipped
automatically.
GSM: A
gsm module is permitted; constants 12 and 13 need to be set!
Make your selection using the
+/- T
buttons and confirm it with the
i
button
(control via the gsm module is described in detail in the instruction manual for GST1)
