INSTALLATION
4.3.1 DESCRIPTION OF THE AUTOMATIC MODE CYCLE
When the letter A appears on the display it indicates that the Automatic cycle has been selected. In the Automatic cycle the
appliance expresses its maximum operating flexibility by optimizing the fuel consumption. If, for example, the temperature
is set (7) at 70 °C the five speed ratios will be automatically distributed between 61 and 70°C so that when the temperature
reaches 70°C the appliance will be running at the minimum power. The level at which the minimum is reached can be
changed by means of button (2). If the value of the button (2) is increased or reduced all the power steps will be redistributed
in the temperature scale.
Consequently, we recommend you find the appropriate level at which the SET POINT minimum is reached in order to
optimize the heat produced by your heater.
If, for example, the SET POINT is set at a high temperature such as 73°C the appliance will attempt to go to that level in
the shortest time possible by modulating the power as it approaches the set temperature. There is no point in setting high set
point temperatures when the conditions of the environment do not require them. With time and experience you will learn
which set points are best for your particular needs.
If the combustion power is not absorbed by the plant above 76 °C, the appliance will shut off temporarily and STOP appears
on the display (6). The heater starts up again at 74 °C.
4.3.2 DESCRIPTION OF THE MANUAL MODE CYCLE
When the plant is operating in manual mode the letter A disappears from the display. The power expressed in this cycle
remains constant independently from the power absorbed by the plant. The plant pump is always activated at anticondensation
temperatures, that is above 61 °C. In this case as well, it is possible to set a set point temperature above which the appliance
will run at minimum power. If an overly-high power level for plant absorption is set, above 75 °C the appliance will shut off
temporarily and the word STOP appears on the display (6). The heater will automatically restart at a temperature of 74°C.
