The Honeywell ST699 timer in my elderly parents home has burnt itself out. I've bought a Siemens rwb29 but the wiring guide does not say where to move all the wires I have. In addition, it looks like the earth wire is not being used for earth but something else. Besides the N & L there are 2 black wires and the earth wire.
Here is the current wiring for the ST699:
