wiring a salus RF thermostat

I'm going to be wiring up a Salus Rf thermostat to a Saunier-Duval combi and need a little clarification. As far as i can see the combi outputs 230v and the Salus receiver accepts 230v by default. The main terminal on the combi has N, L, thermostat, frost stat. there is another terminal with a link wire across (i'm assuming this could be 24v).

Am i right to take a live from the combi terminal-thermostat and run this wire to the S/L on the receiver. The receiver also needs a seperate 230v L and N.

If the link wire in the second terminal is for voltage free then what would i run to the receiver. it can be wired up volt free -by removing a link-as it has connections for NO (switched live-volt free) COM (volt free feed) as well as L + N.

Thanks. I'm normallly fitting Valliants/Worcesters where the receiver just slots into the boiler.

If you have or can arrange a volt free pair of contacts on the receiver then its usually just a matter of connecting them to the terminals which are currently linked.

However, its always so obvious to me when looking at it, but assure yourself that its correct before powering anything.

You are dealing with some expensive bits if you are not sure what you are doing.
