I have evohome with eTRVs and a BRD91 controlling the boiler, plus another BRD91 opening a zone valve on some UFH (which is bound to the main unit).
All "optimisations" are turned OFF.
It mostly works, but it does some decidedly odd things at times. For example - this morning: all zones are well below their setpoints, AND economy mode is switched on (thus: -3deg C, or so I'm told).
And yet: evohome is CFH roughly every 10 minutes, burning for about 1 minute, until sometime around 10:30 when just as mysteriously it stopped.
Is there any way of figuring out WTF evohome believes it needs to CFH ?!
