Checks during and after the first commissioning
Following commissioning, check that the Family Aqua Condens 3.5
BIS, boiler performs the start-up procedures and subsequent shut-
down properly as described below:
- Press button 1,
(ON/OFF)
- Press button B, select heating water temperature, and turn the en-
coder A to select the desired value
- Press button C, select DHW temperature, and turn the encoder A
to select the desired value
- Generate a heat demand by acting on the room thermostat or
hourly timer (external)
- Also check the domestic hot water operation by opening a hot wa-
ter tap.
- Check the full stop of the boiler by turning off the system's main
switch.
After a few minutes of continuous operation, the binders and manu-
facturing waste will have evaporated, you can then perform:
- the supply gas pressure check
- the combustion check.
