6.7. Replacing the modulation PCB
When replacing the PCB, it is required to carry out a few
checks and set a few parameters through the LCD control or
SmartEASY/WEB.
Every AKY equipment has a list of pre-programmed default
values. It is advisable to update the list at every change performed
on site in order to be able to reprogram a spare PCB if needed.
* The following information only applies to AKY boilers; for the
other equipment using the same modulation PCB, refer to the
relevant manual.
Check the hardware configuration of the PCB
Modify the address of the PCB with the switches, copying the
exact configuration of the PCB that was just replaced.
Programming the parameters
The parameters that must be programmed are the following:
•
d0, d1, and d5 - to identify the type of equipment;
• b1, b2, b3 - regulate the motor revolutions of the flue fan;
•
S1 - enables the NTC1 hot water delivery probe;
•
S5 - enables B2 probe for water pressure control;
• S6 - enables B3 probe for water flow rate control;
•
H11 - enables Y1 output (PWM2) for water circulator
modulation;
•
b16 - ID5 input management (fault F35) concerning the
TDOOR burner door thermostat (for AKY100 only);
•
b17 - ID6 input management (fault F38) concerning the
TFUMI fume thermal fuse.
•
H16 circulator modulation;
•
H17 PWM (Y1) or 0/10V (Y2) output according to “direct"
or “reverse” logic
Programming the parameters - Operating mode
Parameters can be modified from the LCD display on the machine
or, alternatively, from SmartEASY/WEB.
SmartEASY/WEB can be used to access all parameters
[see tables on following pages]; parameters have passwords,
which are issued by the APEN GROUP service centre.
Please refer to SmartEASY/WEB manual for instructions for the
procedure for access and modification of functional parameters.
Please remember that all changes to parameters must be done
with the burner OFF.
6.8. Programming with LCD Display
The parameters can be displayed and changed only if they
have been enabled by entering the password from
Abi
menu.
To perform the change, the PCB address must be Ø, otherwise
the PCB address must be changed.
Abi (enabling change of setpoint)
The
Abi
function has the following passwords:
•
001: enables the change of boiler setpoints under
Set
menu;
•
007: enables the change of boiler setpoints under
Set
menu
and of boiler parameters under
Par
menu.
Once the password is enabled, if no key is pressed for 10 minutes,
the programme automatically returns to the machine status.
Move using the menu arrows, select the parameter or setpoint
to be displayed with ENTER, change the parameter by pressing
the arrow keys (↑ to increase ↓ to decrease) until the desired
value, then press and hold ENTER for at least 3 seconds; the
display flashes to indicate that the value has been stored.
Setpoint Menu
For the meaning and the default values, please refer to the
parameter table.

Parameter Menu
The
Par
submenu allows the access to "b" and "d" parameters:
from b1 to b17
burner parameters
from d0 to d9
boiler operation configuration.
For the meaning and the default values, please refer to the
parameter table. Besides "b" and "d" parameters, the following
parameters can be changed:
S1
Modulation probe enabling
SP1
ST1 hysteresis
(only if the probe is used as temperature limit)
tH1
Maximum temperature of the modulation probe,
switches the burner off regardless of the other
conditions set
S2
Not used
P2
Not used
S5
Activates water circuit pressure control
P5
Hysteresis on ST5 value, water pressure
S6
Activates water flow control
P6
Hysteresis on ST6 value, water flow
H11
Activates circulator speed electronic control
