Replacement Wireless Thermostat Wiring

I am replacing my old RF thermostat (Tower RF-205) with a Heatmiser RF-Switch but just wanted confirmation on the wiring. The old thermostat has 4 terminals. Live and Neutral I'm happy with but for some reason they have labelled the other two Out 1 and Out 2.



The new receiver has a ton of terminals but assuming I am replicating only existing wiring to control the central heating I assume I connect L,E,N from Mains, COM1 in the below diagram to L and NO1 to what is currently connected to 1 in the above diagram (Out 2).



Can anyone please confirm. Photo of existing (working) wiring below:



Many thanks in advance. Boiler is a Vaillant ecoTec 832 in case that's helpful.

If you cannot work that out, then I am afraid you really should not be touching it. Get an electrician.

You mean you confirm that my assumption above is incorrect? Happy to get a spark in if I am

Nice try John
