I am trying to replace a Honeywell T6360 room thermostat with a Siemens RDD10 (not 10.1) digital thermostat.
The Honeywell wiring has 4 wires, I have identified from the wiring diagram inside the cover; Earth, Live (red), Neutral (Blue) and Neutral/Load (Yellow).
The Siemens requires four connections, however, none of them are Earth, so I have 3 wires for four connections.
Here is a manual for the RDD10, page 7 shows the wiring diagram for the RDD10 on the left (the right is the RDD10.1 which is the battery model).

Can anyone suggest what I should wire, I guess Neutral (Blue) goes to "N" and Neutral/Load (Yellow) goes to "Q14". I've tried Live (Red) in both "L" and "Q11" separately but in "L" I get power but the control is not working, in "Q11" there is no power at all.
TIA
