VARIABLE SPEED CIRCULATOR WITH MAXIMUM FIXED
SPEED MODE (P90 = 1)
In this mode the modulating circulator runs continuously at full speed.
Used on systems with high pressure drops in which it is necessary
to make the most of the boiler discharge head in order to ensure a
sufficient circulation (system output at maximum speed less than 600
litres per hour).
Used in the presence of hydraulic separators with high output in the
downstream circuit.
In operational terms:
- Enter parameter 90
- Set the parameter = 1
4 - EXCEPTIONAL USE OF A STANDARD CIRCULATOR WITH-
OUT REGULATED SPEED (P90 = 0)
This mode should be used in exceptional cases in which a traditional
circulator without speed adjustment is used in the boiler. It assumes
that the adjustable speed circulator has been removed and replaced
with a non-adjustable speed circulator.
The BE06 card connected to the CN9 connector must be
removed and replaced with a connector with jumper to be
inserted again in the CN9 connector. The latter connection is
mandatory and if not performed can cause system malfunc-
tions.
In operational terms:
- Enter parameter 90
- Set the parameter = 0

3 - INSTALLATION
3.1
Receiving the product
The Family Aqua Condens 3.5 BIS boiler is supplied in a single
pack protected by cardboard packaging.
The boiler is supplied as standard with the following material:
- Instruction booklet for the installer and user
- Bar code labels
- Pre-assembly template
- Package with plumbing fittings
- External probe
- Plastic pipe
- LPG conversion kit.
The instruction booklets are an integral part of the boiler and
there it is recommended to read them carefully and keep them
in a safe place.

Handling
After unpacking, handling of the boiler is done manually using the
support frame (fig. 4).
3.4
Boiler installation room
The Family Aqua Condens 3.5 BIS boiler can be installed in vari-
ous types of room, as long as the combustion product discharge and
combustion air suction are outside the room itself.
In this case, the room does not require any ventilation opening since
the Family Aqua Condens 3.5 BIS boiler has an "airtight" combus-
tion circuit in relation to the installation environment
Consider the clearances necessary to access safety and ad-
justment devices and to perform maintenance operations.
Check that the electric protection level of the appliance is suit-
able for the installation room characteristics.
If the boilers are supplied with fuel gas of a specific weight
greater than that of the air, the electric parts will have to be
positioned more than 500mm above ground level.
3.5
Installation on appliances that are old or that need to
be updated
When the Family Aqua Condens 3.5 BIS boiler is installed in old
systems or systems being updated, verify that:
- The smoke pipe is suitable for the temperature of the combus-
tion products with condensation, calculated and built according to
Standard, is as straight as possible, airtight, insulated and has no
blockages or narrow sections. It is equipped with appropriate con-
densate collection and discharge systems
- The electrical system is installed in compliance with the specific
standards and by qualified personnel
- The fuel supply line and eventual tank (LPG) are made according
to specific Standards
- The expansion tank ensures the total absorption of the dilatation of
the fluid contained in the system
- The flow rate and head of the circulator are suitable to the charac-
teristics of the system.
- The system has been washed and cleaned of mud and grime,
de-aerated and water tight.
- The boiler condensate drain system (siphon) is connected and
routed to the collection of "white" water.
- There is a treatment system for when the supply/make-up water
is particular (the values in the table can be used as reference
values).
