swiss_guy:
The Voltage starts from 0V to the measured values when i hear the click in the gas switch. After a few seconds (need to count exactly) i would say, 3-5secs, the voltage decreases within 1sec back to 0v.
The ignititor is good to hear after the gas switch "clacking sound", its a very silent frequently pulsing sound (ca 3-4secs)
To your question: Do you see voltage on JP2/pin2 simultaneously with ignition "buzz"? >>>> i need to verify this tonight, i feel like it is the same time, but not 100% sure.
swiss_guy:
i measured again
PIC Pin 26 5.1v - 5.4v (while igntion is active)
PIC Pin 27 0v
JP2 Pin 3 12.8v - 13.0v constant (while igntion is active)
JP2 Pin 4 12.4v - 1sec 12.8v, then 12.5v (while igntion is active)

Being busy these days my response have delayed but some quick notes here anyway:
- As you may noticed in #1. for gas to flow it takes two (solenoid)valves to operate.
The main (security)valve which is always needed.
And
one or both of heating power control valves (2kW or 4kW).
All these requires a holding voltage to keep open and at least a pulse of actuating
voltage to open. Those LEDs tells only of holding voltage of heating power control valves,
they do not tell anything about valve actuations.
So, the "clacking sound" tells about opening of one valve. Distinguishing of two valves
to open is needed. Without any electrical measuring you might try to touch those solenoids
to feel if they operate.
There is another way to check gas flow wery directly:
As you open the bottle valve shortly, then if you later open some gas appliance valve (f.e.
gas stove) you may hear "a hizz" and may even light it up for a second. That is also a practical
way to check for leaks in system. Now, if you have tried to start your heater in meantime and
found that gas is disappered from distribution lines, you know that your Aquaflex had succeeded
to open gas flow at least for a moment (during starting sequence). If there is still pressure
left in lines then one of the needed valves has failed to open.

@Mjerica
Sorry, i was also not checking since last friday (the website was also not working for 2 days, at least in Switzerland)
i will try the mentioned tests.
Other question:
When i start the heater on electric power, with mode 1 (1kw) no matter what temperature i set, the system keeps heating up until i feel like in a sauna.
Could this be related to the temperature senros (rt1) or the potentio meter (temperature selector) which is broken?
thanks again

Se liittyy ohjauspaneelin lämpötila-anturiin tai trimmeri potentiometriin ( lämmön säätö ).
