Glow worm boiler not heating

bullinn1

Hi chaps, hope you can help I have a Glow worm Ultracom 38cxi, HW is fine but CH is not working I turned it on last week and all went well but I struggled to turn it off so I just shut down everything, it appeared to be back to normal, all lights on, all controls OK, water heats ok, today I thought I'd have a little heat, "boosted" on the Hive thermostat and boiler didn't respond, I think I've done everything (it was 'serviced' a few months ago) ... any advice very welcome ... here are some pics of the various gizmos:

Problem solved by a nice chap from another forum ... the "flow temperature" was down .... whatever that is ?
