Here you can set the limit of the minimum adjustable tempera-
ture. When using the GSM module, you will be informed by an
SMS that the room temperature has dropped below this value.
Select within the range
from 3°C to 10°C
(by 0.5°C).

CONTROL TYPE
Press the “
MENU
“button twice; select the CONST mode by tur-
ning the “ “ button, and confi rm with the “
“button.
Language selection (CZ/PL/EN/DE).
Choose the language by turning the“ “ button, and confi rm
with the“
“ button.
MINIMUM CONTROL TEMP.
Set the value by turning the“ “ and confi rm “
“.
MAXIMUM CONTROL TEMP.
Selection of regulation type:
PI = proportional-integral control
The PI-control principle consists in comparison of the cur-
rent room temperature with its desired value.
The PI-control aims at achieving and maintaining
the desired temperature without overshooting
(see the graph). For correct function of the PI-control,
set the control parameters according to the type of
the heating system with respect the room thermal
inertia; see
CONST 6
.
Note: If the PI-control is selected, CONST 5 is skipped
automatically.
(CONSTANTS)
(Czech is factory preset)
(factory setting of 5°C)
(factory setting of 39°C)
Here you can set the limit of the maximum adjustable tempera-
ture. When using the GSM module, you will be informed by an
SMS that the room temperature has risen above this value.
Select within the range
from 15°C to 39°C
(by 0.5°C).
Set the value by turning the“ “ and confi rm “
“.
(PI-regulation is factory preset)
Choose the control type by turning the“ “ button, and con-
fi rm with the “
“ button.
HS = hysteresis
Difference between the desired and current temperature.
If the hysteresis is 1 °C and the desired temperature is 20 °C, the ther-
mostat switches off at 20 °C, and on at 19 °C (see the graph).
For correct hysteresis function, set the parameters according to the
heating system type; see
CONST 5
.
Note: If hysteresis is selected, CONST 6 is skipped automatically.
