I've installed the extension kit on a glow worm betacom 4 30c combi.

I removed a Drayton rf receiver and installed the extension kit on the "bus" + and - connectors as instructed.

Removed the timer as instructed from boiler.

Boiler is on

Extension kit is synced and light is pulsing.

No heating....

Help please.
