Brink bypass valve error

[Ultima357]

Hi everyone. My 4 Yr old Brink Flair 400 has just thrown up a wobbly on the bypass valve, putting up an error code and basically then not responding to my commands. The unit is doing the initialisation every so often, but then says error. Taking the exchanger out and inspecting the valve I can see no issues and it fully cycles during the initialisation. I've removed it and replaced it and can't see any damage or problems with the cabling, so a little bemused as to why I'm getting the error. I've powered down and rebooted, leaving it for a few hours in between, but still no joy. The only odd thing I can see is that during initialisation, it starts to move and then stops after the top edge has travelled around 6cm, shunts back a couple of cm then fully travels to the closed position, then returns to open. 

 

Only thing I can think is there must be a positional sensor that is not working properly. Any ideas?

Sounds like a sensor issue. Looking for a feedback it's not seeing?

Had this issue on my salda, I taped the contact shut so the error would go away. It's the Internal bypass so it's never needed as we never get temps low enough for it to activate.

Following a call to CVC, the company that originally supplied the unit, and after discussing the problem, the tech support team suggested a firmware flash and emailed me the files. Simple to apply via plug in USB slot. Update was automatically applied and the problem cured. Great support from the team at CVC Systems.
