Hi,
having some real struggles with my (crappy) Ferroli Optimax HE31c combi boiler. It has never had a thermostat and we've used the inbuilt clock as per the manual below:

Fitted underfloor heating and the wiring centre (Heatmiser UH8-RF) uses a 'boiler enable' :

I've connected the relevant terminals with a wire to my boiler bit (72 on the manual - pins 5 and 6) and when the wiring centre calls for heat the boiler just doesn't respond.
Can't make head nor tail of it. I've tried the following:
Removed the 'jumper' on 5 and 6 of the boiler that is there and that makes no difference.
Can some kind soul suggest something please?
Thanks
