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
