MYNUTE X
Using the interface it is possible to access, using the SETTINGS menu, a series of
parameters that can be programmed to allow you to personalise the operation of the boiler
based on the type of system. Set the parameters according to the desired operating modes.
4.3 Time band scheduling function (room thermostat)
If the heating system is managed by a room thermostat, and therefore without programming
timing, the programming timing on the boiler interface can be enabled by setting in the CH menu
the parameter POR = 1.
To access the programming timing menu press the keys B+D for at least 2sec.

The displays appears as in the following figure:
Using the , arrows select the day or the pre-selected group of days:
1-2-3-4-5-6-7 programming the individual days
1-5 programming from Monday to Friday
6-7 programming from Saturday to Sunday
1-7 programming the entire week
With the key you confirm the selection made and you pass to the programming of the

time bands, with the key you exit the programming timing confirming the changes
made.
With the key you exit without saving the selections.
Setting the Time Bands
- The display shows TIME ON, press
the time, confirm with .
- The display shows TIME OFF, press
change the time, confirm with .
- TIME ON, is displayed again, then the programming of the time bands is resumed up to
the maximum number of programmable bands (four), or else
the bands set and you move on to the programming of the next day.
For each day of the week it is possible to programme up to 4 bands, each one having a start
time and an end time.
Outside these time bands, heat requests from the room thermostat are ignored.
The central heating time bands enabled by default are:
07:30 - 08:30 / 12:00 - 13:30 / 18:00 - 22:30 from MON to FRI
08:00 - 22:30 from SAT to SUN.
When heating programming timing is enabled pressing the keys C+D allows you to move
from AUTO programming timing to MAN ON or MAN OFF.

Description of the settings menu
Some of the following functions might not be available depending on the access level and
the type of machine.
SETTING
TIME
From this menu the time and the number of the day of the week can be adjusted.
TIME PROGRAM
From this menu you can access the menu for adjusting the heating programming timing. For each
day of the week it is possible to set up to 4 bands, characterised by a starting time and an end time.
It is possible to access the same menu directly from the main screen by pressing the keys B+D at
the same time for at least two seconds (see paragraph "4.3 Time band scheduling function (room
thermostat)").
COMB
GAS TYPE
This parameter allows you to set the type of gas.
0 = methane gas - factory setting
1 = LPG
BOILER TYPE
Set this parameter for the type of boiler, see the relative paragraph "4.27 Replacing the AKM board"
for more information.
COMBUSTION OFFSET
This parameter allows you to reset the factory settings of the combustion, see the relative paragraph
"4.28 Combustion Control Parameters" for more information.
CONF
HYDRAULIC CONFIGURATION
This parameter allows you to set the type of hydraulic configuration of the boiler:
0 = ONLY HEATING
1 = INSTANTANEOUS FLOWSWITCH
2 = INSTANTANEOUS FLOWMETER
, change
3 = STORAGE CYLINDER WITH PROBE
4 = STORAGE CYLINDER WITH THERMOSTAT
The factory setting for this parameter is 1. When replacing the electronic board make sure that
,
this parameter is set to 1.
WATER TRANSDUCER
This parameter allows you to set the type of water pressure transducer:
0 = water pressure switch
1 = pressure transducer
The factory setting for this parameter is 1, do not change! When replacing the electronic board make
sure that this parameter is set to 1.
AUTO WATER FILL ENABLE
This parameter allows you to enable the "semi-automatic filling" function since the boilers have a
pressure transducer and a filling solenoid valve installed.
The factory setting for this parameter is 0, do not change! When replacing the electronic board make
sure that this parameter is set to 0.
BEGIN SYSTEM FILLING
NOT AVAILABLE ON THIS MODEL
AIR PURGING CYCLE
This parameter allows you to disable the vent cycle function; the factory setting is 1, set the
parameter to 0 to disable the function.
MIN
This parameter allows you to change the minimum number of the fan's rpm. Do not change!
MAX
This parameter allows you to change the maximum number of the fan's rpm. Do not change!
MAX_CH
This parameter allows you to change the maximum number of the fan's rpm in heating mode. Do
not change!
RANGE RATED
This parameter allows you to change the heat output in heating mode, the factory setting for this
parameter is MAX_CH and can be programmed within the MIN - MAX_CH range.
For more information about the use of this parameter see the paragraph "4.19 Range rated".
