If you search for the brewtus Control Board Retrofit you get a great PDF that shows you the wire config for a RL0 1E/SIC/F + LED or 01.00.0039 Whic pretty much matches the old RL 1E/2C+KNC/F with the bonus of two internal relays instead of 1.
I can not find that newer Giemme unit in the UK. My old one I've repaired twice, new transformer and new relay as the do burn out but my repairs were a bit hand fisted so I thought time to replace with new. I took a punt and bought the 01.03.0036 and hooked it up. Bang! oops did something wrong. After much web searching turns out L doesn't mean live it means light, so I had hooked up neutral to the reservior low level light which is on one of 3 relays and normally closed. I burnt out the trace. Fortunately this is not needed as I don't use a reservoir. Once I realised the pinout all is good and it's in and tested. You have to ground out the reservoir sensor or it thinks it's empty and won't heat the steam boiler. Thought and smoked £85 quid but in the end I'm all good. The contacts on the relay did burn. I pulled it appart to make sure it's not fused and in the process broke both wires off the coil but managed to re-solder them and the relay is working fine. I may replace it one day. Thought I'd share for anyone wanting to replace the old control unit. This one has 3 internal relays so hopefully longer lasting.
