Our boiler has recently started to ignore its instructions from the wireless control. It comes on at different times and generally stays on, only stopping when switched off via the central control on the front panel. We've changed the batteries twice in the remote and reset the boiler a few times with no change. I've checked the pressure and that's fine, operating within the green zone (1.0 to 2.5). It's just over three years old and has been great so far. Any ideas and suggestions as to can be wrong and a fix gratefully accepted. Many thanks.
