Adjusting heating water temperature with an external sensor
connected
When an external probe is connected, the value of the delivery temperature
is automatically chosen by the system which rapidly adjusts ambient tem-
perature to the changes in external temperature. Just the central segment
of the bar is illuminated (Fig. 7).
To increase or decrease the temperature with respect to the value automa-
tically calculated by the electronic board, turn the heating water selector
clockwise to increase and anticlockwise to decrease. The bar segments
light up (at every comfort level), correction tolerance lies between - 5 and +
5 comfort levels (Fig. 7). When choosing the level of comfort, the digit area
of the display shows the required level of comfort while the bar shows the
matching segment (Fig. 8).
Adjusting domestic hot water temperature
CASE A -
only heating - adjusting not applicable
CASE B - only h water tank with thermostat: in this condition every
time there is a request from the water tank thermostat, the boiler supplies hot
water to preparing domestic hot water. During this operation on the display
the icon flashed.
CASE C -
only h water tank with sensor: to adjust domestic hot water
temperature storaged in the water tank, turn switch D (Fig. 9): clocwise to
increase and anticlockwise to decrease. The bar segments light up (every
3°C) as the temperature is increased. About 4 seconds after the selection
has been made, the modification is memorised and the display returns to
the delivery temperature read by the sensor.
Working the boiler
Adjust the ambient thermostat to the required temperature (approx. 20°C).
If there is a demand for heating water, the boiler starts and the symbol is
shown on the display (Fig. 10). The boiler will remain working until the set
temperatures are reached, after which it will go on stand-by . In the event of
ignition or operating faults, the boiler will perform a “safety stop ”.
The flame symbol will go out and the fault code and will be displayed
(Fig. 11). For a description of faults and how to reset them, consult chapter
“Troubleshooting”.
