I have a Sunvic SP35 control box (timer?) attached to my Glowworm Economy
central heating boiler.
I turned the SP35 off at the mains last night, and it's been off for about
24 hours. I've now turned it on again and the LCD is coming on, but it won't
accept any input (such as trying to set the time, activate the boiler etc).
Can anyone think about why this is? I've also tried leaving it for 10
minutes, and also re-lighting the boiler!
Sorry to sound so totally DIY dumb!
