Fast flashing (frequency 0.1 sec. on; 0.1 sec. off; duration 0.5) input/
output function CTR (Environment Automatic Adjustment System).
By setting the heating water temperature selector in the zone marked
by symbols in bold type - temperature value from 55 to 65 °C - the CTR
self-adjusting system is activated: the boiler varies the delivery tempe-
rature according to the closing signal of the ambient thermostat. When
the temperature set with the heating water temperature selector is
reached, a 20 minutes count begins. If during this period the ambient
thermostat still requests heat, the value of the set temperature
automatically increases by 5 °C.
When the new value is reached, other 20 minutes count begins.
If during this period the ambient thermostat still requests heat, the value
of the set temperature automatically increases by 5 °C.
This new temperature value is the result of the temperature set manually
with the heating water temperature selector and the increase of +10 °C
of the CTR function.
After the second increasing cycle, the temperature value is restored to
the value set by the user and the above mentioned cycle is repeated
until the ambient thermostat request is fulfilled.
Fixed green
if there is flame, the boiler works regularly.
Red led
The red led indicates a boiler lockout due to the following faults:
Fixed
- flame lockout
- air pressure switch intervention (after transient phase)
- NTC heating probe
- ACF electronic fault alarms
- water pressure switch (after transient phase)
Flashing
- limit thermostat intervention
After a "SAFETY STOP" and fault code appearing, wait at least 10
seconds before restoring ignition conditions.
To reset operation, place the mode selector to
the desired position (summer or winter).
Green flashing led + red flashing led
When the LEDs flash simultaneously it is a domestic water probe alarm
The boiler works regularly, but stability of the domestic hot water tempera-
ture is not guaranteed.
Contact the Technical Assistance Service for a control.
When the LEDs flash alternatively it means that there is a calibration pro-
cedure in progress.

4.5 ADJUSTMENTS (FIG. 27)
The boiler has already been adjusted by the manufacturer.
For LPG gas: the boiler has been regulated in I3B/P (G30) category. If you
need to regulate in I3+ or I3P categories (G31) exclude pressure regulator.
If it is necessary to adjust it again, for example after extraordinary
maintenance, after replacement of gas valve or after gas conversion, carry
out the following procedure.
The maximum output adjustment must be carried out in the
sequence indicated exclusively by qualified personnel.
MAXIMUM POWER ADJUSTMENT
- Turn the main system switch to "OFF"
- on the control panel:
- set the mode selector to
- turn the domestic hot water temperature selector to maximum (2)

and then turn it back to

(summer)
- unscrew the screws fastening skirt to framework
- remove skirt
unscrew the screw fastening the instrument panel
- unscrew the screw of the pressure test point, downstream from the gas
valve, by about two turns and connect up the gauge
- turn on a hot water tap to maximum capacity (leave it running for at least
two minutes before calibrating)
- check that the pressure on the pressure gauge is stable; or with a
milliammeter in series to the modulator, make sure that the modulator
supplies the maximum available current (120 mA for G20 and 165 mA for
LPG).
- carefully prise out the protection cap of the adjustment screws, using a
screwdriver
-
disconnect the compensation tap from the air box
- with a fork spanner CH10 use the adjustment nut of the maximum output
in order to obtain the value indicated in multigas table
MINIMUM DOMESTIC HOT WATER ADJUSTMENT
- disconnect the modulator faston
- wait until the pressure on the pressure gauge is stable at minimum value
- paying attention not to press the internal shaft, with a socket head screw
turn the red adjustment screw to regulate the domestic hot water minimum
temperature and calibrate until the pressure gauge reads the value
indicated in multigas table
- reconnect the modulator faston
- close the domestic hot water tap
- carefully refit the protection cap of the adjustment screws.
MINIMUM AND MAXIMUM HEATING ELECTRIC ADJUSTMENT
The "electric adjustment" function is activated and deactivated
exclusively by the jumper (JP1).
The function can be enabled in the following way:
- by powering the card with the jumper JP1 inserted and the mode selector
in winter position, independently from the possible presence of other
operation request.
- by inserting the jumper JP1, with the mode selector in winter position,
without heat request in progress.
By activating the function the burner is ignited through simulation
of heat request in heating.
To perform calibration operations, proceed as follow:
- switch off the boiler
- remove the shell and access the card
- insert the jumper JP1 to enable the knobs placed on the control panel to
the minimum and maximum heating adjustment functions.
- make sure that the mode selector is in winter position
- power the boiler
Electric card in voltage (230 Volt)
- turn the heating water temperature adjustment knob (1) until it reaches
the heating minimum value as indicated in the multigas table
- insert the jumper JP2
- turn the domestic hot water temperature adjustment knob (2) until it
reaches the heating maximum value as indicated in the multigas table
- remove the jumper JP2 to store the heating maximum value
- remove the jumper JP1 to store the heating minimum value and to
get out the calibration procedure
- reconnect the compensation inlet to the air distribution box
Disconnect the pressure gauge and retighten the pressure test point screw.
