Long delays from Evohome until BRD91 activates

[Fly100]

Hello all,

Anyone had an experience with long delays from Evohome sending the 'on' signal and the BRD91 actually turning on.?

Mine started this morning with the Heating not coming on. Investigation showed the rad valves open but the BRD91 not on, having seemingly ignored its on instruction for the morning heating run, oddly the hot water had fired . So testing followed and there is a 3-4 mine delay in the on time until the BRD91 actually turn on and the heating fires.

Any one have experience with this ?

Thanks
FLY
