The battery indicator in my automatic thermostat suggested they needed changing, which I
duly did. This resulted in me having to reprogram the daily settings and try to wirelessly
re-connect it to the boiler. Despite me following the instructions on the Worcester Greenstar 30si
boiler documents I have not be successful in doing that. The heating kicked-in, so I had to
turn the c/h switch on the boiler to 'off'.
I'll try again tmw (tomorrow).
