QUADRIFOGLIO B
Sliding temperature
When an external probe (optional) is installed, the corresponding symbol of the outside
temperature is activated on the control panel display. The boiler adjustment system
works with "Sliding Temperature". In this mode, the temperature of the heating system
is adjusted according to the outside weather conditions, to ensure a high level of comfort
and energy saving throughout the year. In particular, as the outside temperature increas-
es, the system delivery temperature decreases according to a specific "compensation
curve".
With Sliding Temperature adjustment, the "Heating adjustment" temperature becomes
the maximum system delivery temperature. It is advisable to set a maximum value to al-
low system adjustment throughout its useful operating range.
The boiler must be adjusted at the time of installation by qualified personnel. Adjust-
ments can in any case be made by the user to improve comfort.
Compensation curve and curve offset
Access the Sliding Temperature menu. Adjust the required curve from 1 to 10 according
to the characteristic (fig. 28) through the parameter "Curve1" and confirm with the OK
button.
By setting the curve to 0, the sliding temperature adjustment is disabled.

Adjust the parallel offset of the curves from 20 to 60 °C (fig. 29), through the parameter
"Offset1" and confirm with the OK button.

If the room temperature is lower than the required value, it is advisable to set a higher
order curve and vice versa. Proceed by increasing or decreasing in steps of one and
check the result in the room.

Outside Temperature Heating OFF
Access the "Out Temp Heat Off" to activate the function: between 7°C and 30°C.
If activated, this function will deactivate the heating demand whenever the temperature
measured by the external probe is higher than the programmed value.
The heating demand will be reactivated as soon as the temperature measured by the ex-
ternal probe is lower than the programmed value.
Adjustments from remote timer control
If the Remote Timer Control (optional) is connected to the boiler, the above ad-

justments are managed according to that given in table 1.

System water pressure adjustment
The filling pressure with the system cold must be approx. 1.0 bar. If the system pressure
falls to values below minimum, the boiler card will activate fault 37 and the number of
the module (fig. 30).

3. INSTALLATION

3.1 General Instructions

THE BOILER MUST ONLY BE INSTALLED BY QUALIFIED PERSONNEL, IN COMPLI-
ANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE
PROVISIONS OF CURRENT LAW, THE NATIONAL AND LOCAL REGULATIONS,
AND THE RULES OF PROPER WORKMANSHIP.
For Switzerland must apply the following installation standards and directives:
• SVGW - Gas principles G1: Gas installation
• EKAS - Form. 1942: Liquid gas directive, part 2
• Cantonal instances regulation (e.g. fire safety regulators)
QUADRIFOGLIO B is a heat generator arranged to operate alone or in cascade (bank).
FERROLI supplies (on request) all the plumbing fittings and fume manifolds for the con-
nection of 2 or 3 units in cascade in configurations of 70 + 70 kW to 320 + 320 +320 kW.
When the generators QUADRIFOGLIO B are installed in cascade with the accessories
provided for by FERROLI, they can be considered as a single heat generator with equiv-
alent total capacity equal to the sum of the powers of all the units connected in cascade.
All requirements of the current rules and regulations applicable to this generator of
"equivalent" total heating capacity must be met. In particular the place of installation,
3
4
safety devices and fume exhaust system must be adequate for the total heating capacity
2
of the bank of units. The requirements given in this manual apply to the single unit as well
1
as connection in cascade. For further information regarding the installation of generators
in cascade, refer to the manual supplied with the cascade connection kits.
The boiler electronics have a function for a managing a cascade of up to 6 units.
A
To create cascade systems with more than three units without using the acces-
sories provided for by FERROLI, it is necessary to arrange hydraulic/gas man-
ifolds of appropriate size and complete with all the safety devices required by
the current regulations, as well as single fume exhausts or manifolds appropri-
ately sized by a qualified technician.
boiler control panel.
The adjustment can be made from the Remote Timer Control menu and the
boiler control panel.
Summer mode has priority over a possible Remote Timer Control heating
demand.
On disabling DHW from the Remote Timer Control menu, the boiler will select
the Economy mode. In this condition, the button detail 10 - fig. 1 on the boiler
panel is disabled.
On enabling DHW from the Remote Timer Control menu, the boiler will select
the Comfort mode. In this condition, with the button detail 10 - fig. 1 on the
boiler panel it is possible to select one of two modes.
Both the Remote Timer Control and the boiler card manage Sliding Tempera-
ture adjustment: Sliding Temperature overrides the boiler card.
