ECO/COMFORT selection

The unit has a function that ensures a high domestic hot water delivery speed and max-
imum comfort for the user. When the device is activated (COMFORT mode), the water
contained in the boiler is kept hot, thereby ensuring immediate availability of hot water
on opening the tap, without waiting times.
The user can deactivate the device (ECO mode) by pressing the 

eco/comfort

 button

(detail 7 - fig. 1). In ECO mode the display activates the ECO symbol (detail 12 - fig. 1).
To activate the COMFORT mode, press the 

eco/comfort

 button (detail 7 - fig. 1) again.

Sliding Temperature

When the optional external probe is installed, the boiler adjustment system works with
"Sliding Temperature”. In this mode, the temperature of the heating system is controlled
according to the outside weather conditions, to ensure high comfort and energy saving
throughout the year. In particular, the system delivery temperature is decreased as the
outside temperature increases, according to a specific "compensation curve”.
With Sliding Temperature adjustment, the temperature set with the heating buttons (de-
tail 3 - fig. 1) becomes the maximum system delivery temperature. It is advisable to set
a maximum value to allow system adjustment throughout its useful operating range.
The boiler must be adjusted at the time of installation by qualified personnel. Possible
adjustments can in any case be made by the user to improve comfort.
Compensation curve and curve offset
Press the 

reset

 button (detail 6 - fig. 1) for 5 seconds to access the "Sliding temperature"

menu; the display shows "CU" flashing.
Use the DHW buttons (detail 1 - fig. 1) to adjust the curve from 1 to 10 according to the
characteristic. By setting the curve to 0, sliding temperature adjustment is disabled.
Press the heating buttons (detail 3 - fig. 1) to access parallel curve offset; the display
shows "OF" flashing. Use the DHW buttons (detail 1 - fig. 1) to adjust the parallel curve
offset according to the characteristic (fig. 6).
Press the 

reset

 button (detail 6 - fig. 1) again for 5 seconds to exit the "Sliding Temper-

ature" menu.
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.

Adjustments from Remote Timer Control

A

If the Remote Timer Control (optional) is connected to the boiler, the above ad-
justments are managed according to that given in table 1.

Table. 1

Water system pressure regulation

The filling pressure read on the boiler water gauge with the system cold must be approx
1.0 bar. If the system pressure falls to values below minimum, the boiler stops and fault

F37

 is displayed.

3. INSTALLATION
3.1 General Instructions

B

This unit must only be used for its intended purpose. This unit is designed to
heat water to a temperature below boiling point and must be connected to a
heating system and/or a water supply system for domestic use, compatible with
its performance, characteristics and its heating capacity. Any other use is
deemed improper.

BOILER INSTALLATION MUST ONLY BE CARRIED OUT BY QUALIFIED PERSON-
NEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL
MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRESCRIPTIONS OF THE
TECHNICAL STANDARDS (BS), ANY LOCAL REGULATIONS AND THE RULES OF
PROPER WORKMANSHIP.
Incorrect installation can cause damage or injury for which the manufacturer declines
any responsibility.

Installation of this unit must be carried out in strict compliance with the present
instructions and the following regulations applicable in Great Britain.

Gas Safety Regulations (Installations & Use).
Local Building Regulations..
The Building Regulations (Part L).
The Buildings Standards (Scotland - Consolidated) Regulations. British Standards
Codes of Practice (BSI):

Model Water By-Laws

For Northern Ireland, observe the current applicable regulations.

Safe handling of materials

Pay attention when handling the boiler insulation panels because the material they are
made of could irritate the skin. No part of the boiler contains asbestos, mercury or CFC's.

Advice for transport and handling

For lifting and transport always take suitable safety precautions: keep your back straight,
bend knees, do not turn your body, move feet, avoid bending forward or sideways and
keep the load as close as possible to your body.
If possible, use a trolley or other suitable means to carry the boiler.
Grip the boiler firmly and, before lifting it, try and find the point where the load is concen-
trated in order to establish the centre of gravity and suitably reposition yourself.

3.2 Place of installation

The combustion circuit is sealed with respect to the place of installation, therefore the
unit can be installed in any room. However, the place of installation must be sufficiently
ventilated to prevent the creation of dangerous conditions in case of even small gas
leaks. This safety standard is required by the EEC Directive no. 2009/142 for all gas
units, including those with sealed chamber
The unit is suitable for operation in a partially protected place in compliance with EN 297
pr A6, for temperatures to -5°C. It is advisable to install the boiler under the slope of a
roof, inside a balcony or in a sheltered recess.
Therefore the place of installation must be free of dust, flammable materials or objects
or corrosive gases.
The boiler is arranged for wall mounting and comes standard with a hooking bracket. Fix
the bracket to the wall according to the measurements given in the cover drawing and
hook the boiler on it. A metal template for marking the drilling points on the wall is avail-
able by request. The wall fixing must ensure stable and effective support for the gener-
ator.

A

If the unit is enclosed in a cabinet or mounted alongside, a space must be pro-
vided for removing the casing and for normal maintenance operations

Heating temperature setting

Adjustment can be made from the Remote Timer Control menu and the 
boiler control panel.

Hot water temperature adjustment

Adjustment can be made from the Remote Timer Control menu and the 
boiler control panel.

Summer/Winter Switchover

Summer mode has priority over a possible Remote Timer Control heat-
ing demand.

Eco/Comfort selection

Adjustment can only be made from the boiler control panel.
