Just installed my first one of these and it dosent seem to want to go into heating mode. Sparkies came in and sorted the wiring out but there has since been a vailant time clock added.... Now when the boiler is switched on and there is demand for heat at the central heating it does nothing..No fault code no nothing.. I set it to test and heating works just fine.. Demand for hot water and again the boiler works just fine.. It will not fire under central heating demand at the time clock either.. Im sure this is something very simple and wonder if any you guys have come across this. Before anyone jumps on the gas safe band wagon I got my number 2 weeks ago so yes i am registered but still a bit wet behind the ears with certain boilers.
As a note when i hit - + simultaneously the heating fires for approx 15 mins.
