11.1.3 Available readings at Maintenance Level 2
•
When you are on the main display (if not, press switch T2), press button T10, “info”
•
Press simultaneously, during 3 seconds at least, the buttons T6 and T7
.
•
Press once switch T7,
•
Choose the required parameter by pressing the buttons T8 and T9
•
To go back to the initial display, press the button T2 (if you do not vary anything after 8 minutes you will
automatically go back to the initial display).
Operation values (maintenance level 2)
Code
Description
c0, c7-c9
Not used
c1
Value of the ionization current (must be higher than 5 microamperes)
c2
Fan revolutions per minute
(Rpm) at that moment (multiplay the obtained reading by 100 to have “rpm”)
c3
Operation value between “maximum value defined” and “minimum value defined”
(% PWM)
c4
Percentage of the boiler input/charge at that moment
(%):
Value “0”
minimum output; value “100”
maximum output.
c5
Not available: percentage of operation or of setting of the modulating pump (signal PWM)
c6
Difference between the boiler set-up flow temperature and the real temperature
11.1.4 Available readings at Maintenance Level 3
•
When you are on the main display (if not, press switch T2), press the button T10, “info”
•
Press simultaneously, during 3 seconds at least, the buttons T6 and T7
.
•
Press trice the button T7,
•
Choose the required parameter by pressing the buttons T8 and T9
•
To go back to the initial or normal display, press switch T2 (if you do not vary anything after 8 minutes you
go automatically back to the initial display).
Set-up temperatures (maintenance level 3)
Code
Description
d0, d7-d9
Not used.
d1
Modulating controller set-up temperature (PID controller)
d2
Boiler set-up flow temperature (ºC)
d3
Not available: Set-up room temperature (according to programming and installation)
d4
Not available: set-up D.H.W.S. temperature (according to programming and installation)
d5
Maximum percentage of the fan modulation for the boiler model, respect to the maximum value of the
fan itself
d6
Maximum speed of the fan at maximum output (multiply the read value by 100 to obtain r.p.m.)
11.2 CODES OF THE BOILER OPERATION PHASES
Display
Meaning
00
Boiler in stand-by (the installation does not have any request of heat)
01
Signal of boiler start-up
02
Motor fan is activated (revolutions increase)
03
Phase of pre-venting
04
Time of stand-by (control of the fan speed)
05
Time of pre-ignition
06
Safety time of ignition and ionization control (constant). The image of a flame appears.
07
Safety time of ignition and ionization control (variable)
10
Operation in heating mode
11
Phase not available: Operation of D.H.W.S.
12
Phase not available: Operation of heating and D.H.W.S. in parallel.
20 / 21
Post air venting starts and fan stops
22
Self-test and return to the initial position
99
Alarm / lockout (the alarm code is visualized on the display)
If the phases finish off in a short time, its code is not shown on the display.
