Start Aqua Condens 25/60 BIS
Adjusting the heating water temperature with an external
probe connected
When an external probe is installed, the delivery temperature
is automatically selected by the system, which quickly adjusts
the ambient temperature according to variations in the outside
temperature. If you want to alter the temperature value (increasing
or reducing the value automatically calculated by the electronic
card), use the heating water temperature selector: turn it clockwise
to increase the temperature, or anticlockwise to reduce it.
The correction possibility is between 15° C and 25° C levels of
comfort (0 = 20° C), shown on the digital display by rotating the
knob.
Summer mode
The standard domestic hot water-only mode is activated by
turning the selector to the summer symbol
automatically in response to a request for domestic hot water. The
digital display indicates the temperature of the domestic hot water.
SUMMER MODE
Adjustment of the domestic hot water temperature
To adjust the domestic hot water temperature (for baths, showers,
kitchen etc.), turn the dial with the
the value, or anticlockwise to decrease the value (min. value 37°C -
max. value 60 °C). The boiler is in standby until the burner switches
on following a heat request. The boiler continues to function until
the temperatures set on the boiler are reached, or the heat request
terminates; it will then go back to standby. In the case of a temporary
stop the digital display shows the fault code.
ADJUSTING THE DOMESTIC HOT WATER TEMPERATURE
Heating Temperature Control function (C.T.R.)
Turn the heating water temperature selector into sector highlighted
with white markers to activate the C.T.R. self-adjusting system:
depending on the temperature set on the ambient thermostat and
the time taken to reach it, the boiler automatically varies the heating
water temperature by reducing operating time, thereby achieving
increased comfort and energy savings.

Reset function
To restore normal operation, turn the function selector to
5-6 seconds, and then turn it to the required position. At this point,

4.3 Checks during and after the first commissioning
Following commissioning, check that the Start Aqua Condens
25/60 BIS, boiler performs the start-up procedures and subsequent
shutdown properly by acting on the:
- mode selector
- calibration of the heating water temperature selector and
domestic hot water temperature selector
- requested ambient temperature (by intervening on the ambient
thermostat or programming timer).
Also check the domestic hot water operation by opening a hot
water tap with the mode selector both in summer mode and in
winter mode.
Check the full stop of the boiler by turning off the system's main
switch.
After a couple of minutes of continuous operation to be obtained
by turning on the system's main switch, the mode selector on
(summer) and by keeping open the domestic hot water device, the
binders and manufacturing waste evaporate and it will be possible
to perform:
- the supply gas pressure check
- the combustion check.
