2 - DESCRIPTION
START AQUA 24 BI is a wall-mounted gas boiler for central heating
and domestic hot water, equipped with a 45-litre water tank.
The boiler is controlled electronically with automatic ignition, ionisa-
tion flame control (with a single electrode), modulating in heating and
DHW mode.
It has a B open combustion chamber.
11BS
Switch between heating and DHW mode using an electric 3-way
valve, which is set to heating mode when in standby. To guarantee
the correct water flow in the primary exchanger, the boiler is fitted
with an automatic bypass device.
It is also complete with the safety, expansion and distribution acces-
sories.
The boiler is fitted with an efficient microprocessor control system.
START AQUA 24 BI boilers are also fitted with:
- Pump anti-block function and 3-way valve
- First level anti-freeze (suitable for indoor installations)
- Gas valve complete with stabiliser and slow ignition
- Provision for room thermostat or timer (to be installed outside the
boiler)
- Provision for DHW timer (to be installed outside the boiler)
- Baby Safety function: this function, with jumper JP1 wired in, al-
lows the domestic water storage temperature to be automatically
set at 43 +- 3 °C (electronically disabling the temperature selection
dial). This prevents the risk of scalding if the domestic hot water
tap is turned out inadvertently. Activating this function prevents use
of the anti-legionella function. This function can be activated on
request by contacting the Technical Assistance Service.
- Anti-legionella function: Legionella is a disease that can be caught by
inhaling small droplets of water (aerosol) that contain the legionella
bacteria (this is found naturally in lakes and rivers throughout the world).
The bacteria is eliminated by bringing the stored water to a tem-
perature exceeding 50°C/55°C. It is therefore recommended that
the DHW temperature selection knob be set to the maximum value
at least every 2/3 days to bring the water temperature to 63°C,
maintaining this temperature for at least 5 minutes.
