Hot water temperature adjustment
To set the system delivery temperature, turn the specific knob.
It can vary from a minimum of 30°C to a maximum of 65°C. Turning the knob sets the required temperature
(clockwise to increase, anticlockwise to decrease) that is shown on the display. During the setting, the display
quickly blinks and once defined it stops blinking after 2 sec. and goes back to showing the actual operating
temperature.
If connecting to a remote timer control
(optional), the system temperature
is only governed with the remote
control. By turning the tap water
temperature control knob on the
boiler, the temperature can only be displayed and not changed.
Adjusting the maximum heating output
To adjust the heating power, set the boiler on TEST operation (see "Test operation"). During the ignition phase,
the display shows the ignition power and, immediately afterwards, the heating power. Turn the heating
temperature control knob clockwise to increase the power or anticlockwise to decrease it. The display shows
a percentage ranging from 0 to 100%
(the display blinks during the setting).
The figure shown on the display
indicates the percentage change
between the boiler's minimum and
maximum power. This adjustment is
set on the control panel, also with the remote control connected the system must be free of any errors.
Ignition power adjustment
To adjust the ignition power, set the boiler on TEST operation (see "Test operation"). During the ignition phase,
the display shows the ignition power and, immediately afterwards, the heating power. Turn the tap water
temperature control knob clockwise to increase the ignition power or anticlockwise to decrease it. The display
shows a percentage ranging from 0
to 100% (the display blinks during
the setting). The figure shown on the
display indicates the percentage
change between the boiler's
minimum and maximum power. This adjustment is set on the control panel, also with the remote control
connected.
Adjusting the heating t by changing the delivery-head of the circulator
The temperature drop t (difference in temperature of the heating water between the system delivery and return)
must be less than 20°C and this is obtained by changing the delivery-head of the circulator with its speed
changer (or with the switch).
