Adjustments from Remote Timer Control
If the Remote Timer Control (optional) is connected to the boiler, the above ad-
A
justments are managed according to that given in table 1. Also, the control pan-
el display (detail 5 - fig. 1) shows the actual room temperature detected by the
Remote Timer Control.
Table. 1
Heating temperature setting
Adjustment can be made from the Remote Timer Control menu and the boiler
control panel.
DHW 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 heating
demand.
On disabling DHW from the Remote Timer Control menu, the boiler selects the
Economy mode. In this condition, the button 7 - fig. 1 on the boiler panel is dis-
abled.
Eco/Comfort selection
On enabling DHW from the Remote Timer Control menu, the boiler selects the
Comfort mode. In this condition it is possible select one of the two modes with
the button 7 - fig. 1 on the boiler panel.
Sliding Temperature
Both the Remote Timer Control and the boiler card manage Sliding Tempera-
ture adjustment: of the two, the Sliding Temperature of the boiler card has pri-
ority.
Water system pressure adjustment
The filling pressure with system cold, read on the display, must be approx. 1.0 bar. If the
system pressure falls to values below minimum, the boiler card will activate fault F37
(fig. 15).
fig. 15 - Low system pressure fault
Once the system pressure is restored, the boiler will activate the 120-second
A
air venting cycle indicated on the display by FH.
2. INSTALLATION

2.1 General Instructions

BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSON-
NEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL
MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRESCRIPTIONS OF NA-
TIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP.

2.2 Place of installation

The boiler unit must be installed in a specific room with ventilation openings to the out-
side as prescribed by current regulations. If there are several burners or suction units
that can work together in the same room, the ventilation openings must be sized for si-
multaneous operation of all the units. The place of installation must be free of flammable
materials or objects, corrosive gases, powders or volatile substances that, conveyed by
the burner fan, can obstruct the internal lines of the burner or the combustion head. The
room must be dry and not exposed to rain, snow or frost.
If the unit is enclosed in a cabinet or mounted alongside, a space must be pro-
A
vided for removing the casing and for normal maintenance operations.

2.3 Plumbing connections

Important

The heating capacity of the unit must be previously established by calculating the build-
ing's heat requirement according to the current regulations. The system must be provid-
ed with all the components for correct and regular operation. It is advisable to install
shutoff valves between the boiler and heating system allowing the boiler to be isolated
from the system if necessary.
The safety valve outlet must be connected to
B
a funnel or collection pipe to prevent water
spurting onto the floor in case of overpressure
in the heating circuit. Otherwise, if the dis-
charge valve cuts in and floods the room, the
boiler manufacturer cannot be held liable.
Do not use the water system pipes to earth
electrical appliances.
Before installation, flush all the pipes of the system thoroughly to remove any residuals
or impurities that could affect proper operation of the unit.
Carry out the relevant connections according to the diagram in cap. 4 and the symbols
given on the unit.
High efficiency circulating pump
Circulating pump adjustment with boiler connected to an external hot water stor-
age tank
For proper operation of the boiler ATLAS D ECO COND UNIT with it connected to an
external hot water storage tank, the speed selector (see fig. 16) must be set to position
III.
Circulating pump adjustment without a connection to an external hot water stor-
age tank
The factory setting is suitable for all installations; however a different operation strategy
can be set, depending on the characteristics of the system.

- Setting Dp-v Proportional head (fig. 17)
The circulating pump head will be automatically reduced with the decrease in flow rate
required by the system. This setting is optimum for systems with radiators (2 pipes or sin-
gle pipe) and/or thermostatic valves.
The strong points are the reduction in power consumption with the decrease in system
demand and reduction of noise in radiators and/or thermostatic valves. The operating
range is from min. (1) to max. (7).
