Without the room thermostat connected With the room sensor connected (on the display there is
marked by the symbol .
In case that the room sensor is connected (the order
number of set is 4050485) the boiler is heating according
to the temperature in a reference room with hysteresis 1
°C. Actual temperature in the reference room is displayed
under the symbol .The room sensor is connected on the
clamps of the control unit marked NTC ROOM.
Steps for setting of temperature in a reference room
Press the button , on the control panel, for setting of the
temperature requested press for its increasing or
for its decreasing and confirm it by . After this
confirmation you will go back to main display.
Temperature could be set in scale from 5 to 35 °C, if the
temperature is decreased below 5°C the regulation
function is switched off on the basis of reference room
temperature. The boiler is controlled by the same way as
in previous 2 samples without the importance of the

P20 in the scale 1 - 10 °C. (This parameter could be set regulation activated then this regulation is priority (and
only by authorized service person). the boiler will not reply to room thermostat).
Steps for temperature setting of heating water:
Set the temperature requested by pushing , on the
control panel , on the display is temperature and “OV
TEPLOTA” and confirm by .After confirmation you will
go back to the basic display. The boiler is now heating to
the temperature requested by you. The scale of
temperature setting is 25 80 °C (regarding the setting
below the temperature value 25 °C the marking of
operation mode “SUMMER” = “SU” is lighting, going back
to heating mode is possible only by increasing the
temperature of heating water by the button ) .
If you don't confirm the value during editing till. 10 s, the
boiler is automatically goes back to the previous setting.
We recommend you to use the room thermostat for
economical operation of your heating system
