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...
Sorry, with 2 cables is the picture below.
The cable coming from the BDR91 is the right white one at the top left. As you can see, on the last photo of the previous post (8517), the green-yellow cable (in the ~middle connector, just before the gap) leads to nothing, while it was connected to a...
however, in the wiring box, this green-yellow cable is connected to ... nothing. So, I would imagine the BDR91 is not commanding anything at the moment and that is the issue. It was connected to the rest through one wire of the Honeywell actuator I dropped in April as I thought it was defective...
Thank you.
So:
- HPA2 seems to be dead again indeed. Cannot see the lever coming back when I open manually.
- I just opened the BDR91, and it is cabled this way (cable to the wiring box)
* blue cable on N
* brown cable on L
* connector between second L and A
* green-yellow cable on...
Please, how is everything supposed to be cabled if I drop the HPA2 completely? I think some cables may not be linked together anymore as I dropped the Honeywell actuator, as that may be the reason why the boiler is on despite receiving no signals. I would imagine that by default it is on, unless...
Yes, heating mode burner mode, code S.04. Boiler has been running for 3 hours continuously, with Evohome system off, BDR91 light off and water heater at minimum temperature (I turned it higher a couple of hours ago and heard the TLSC switching on, and then put it back at minimum and heard it...
Hello
I find myself in the unfortunate position of being unemployed at the moment and savings are depleting quickly. I have just started heating a couple of days ago, and I forgot that I noticed already when switching it off in April that the boiler was running continuously, which is not what I...
