Vokera RF Weekly Room Thermostat - HRT-177RS

I keep getting A84 coming up on my thermostat.  Does anyone know what this means please.  There is no indication in the manual.  Thanks

  • Google says a few folk have had the same issue - but I haven't seen an explanation.
    Time to message Vokera? See if they have a Facebook page - that's often a quick way.
  • Yes, contact vokera tech dept.

    What does your regular boiler servicing operative think about the A84 message.

    Does the A symbol looklike a corrupted E symbol ?  E84 is a known issue.
    A  or E messages are alarm or error messages (or similar) alot depends on the third party that made the item and the translation of the original documents.

    I imagine new batteries have been tried and the unit has been reset to original settings (factory reset) Then set up as per the instructions you have.

  • Will contact Vokera, seems to be working ok otherwise.  Will Post their reply if I get anywhere.  Thanks all.
  • That's what the other threads on this reported too - the programmer was otherwise working ok. Some had tried fresh batteries to no avail.
    A real mystery. Please report back when they reply :smile:
  • As expected, I got no response to my email to Vokera.  I did try new batteries though and all seems to be ok now over the last 2 days.  If it happens again I will ring them next time or ask my boiler man when he comes to do the service.  I suspect I may need a new thermostat.  Unfortunately nothing seems to last these days.  Thanks to everyone for all the help.
