thank you. So, after deep investigations:
- the valve to the cylinder is too hard for the actuator. The HPA2 actuator actually works fine but it was blocked in open position as the spring cannot turned the valve off and the switch was continuously activated. So, I left the actuator cabled, but I detached it from the valve and it is now working fine. Valve is of course left open.
- the Honeywell actuator motor is kind of dead. Clacking. So, valve left open and actuator completely removed.
- the other HPA2 actuator on the zone to 1st and 2nd floor works perfectly well and its valve as well. So, I plugged it back as per my photos.
And now everything is working perfectly!
Thank you anyway for the support. It notably helped me ask myself the right questions.
