I have an issue with a Worcester Greenstar 29CDi Classic boiler.
I replaced the old thermostat controller with a smart dual-channel HIVE one.
I did all the wiring following the diagram in the attached picture.
The boiler doesn't work anymore.
Please, any suggestions?
 
Did you remove the old clock?

Picture of your wiring please

Of course, I did. The issue was that the diagram for wiring the HIVE thermostat to the Worcester combi boiler was wrong. Because I've used only the heating channel, the return live had to be connected to the com no 4 on the receiver's pins.
Anyway, it is sorted already, but thanks for your reply.
 
Glad you managed to get things sorted out in time for the cold snap we have had!
