Once again I have found the BRD91 activated when there was no heat demand programmed for any of the valves.
On looking in the Fault Log I discovered an interesting sequence of events:
There was a Comms Failure reported on zone 4b which was restored after 6 days(!). After a further 3 hours and 10 minutes it failed again for another 5 days.
This pattern of restoring and then failing after exactly 3 hrs 10 mins was repeated twice more.
Tests on the comms link to this particular zone show a signal strength of mostly 3, occasionally 2, never 1 or less.
So my question is: what is the significance of the period of 3 hrs 10mins?? Has anyone else seen this phenomenon? What can be done to stop it recurring?
The problem of unexplained boiler firing has now been occurring from time to time for nearly 3 years, see my post at http://www.wordpress-1219309-4387497...and-from-BRD91 and the subsequent discussion at http://www.wordpress-1219309-4387497...ding-corrupted; it was logged by Honeywell in 2015 but I have never heard anything further.
Until I find a solution to this unexplained behaviour we dare not go away leaving the system under the control of Evohome in case we come back to an empty oil tank!
