Does anyone have the instructions for the DT2 digital timer that plugs into the Worcester Bosch Greenstar HE combi condensing boiler?
A service engineer who came to fit a new room thermostat set the timer to 'always on' and forgot to set it back again to on twice a day. Now I find that the instruction manual for the boiler doesn't include the timer, and I can't work out how to program it - they say it's easy, but it's not self-evident to me.
Thanks, PhilG
