Hi, i have a Ravenheat csi 120 (t) low nox combi boiler but there is no room thermostat so i have bought a Salus wirless digital thermostat with RF (RT 300rf).

My problem is the instrucions for wiring are simple enough but i am unsure of which wires in the boiler to use.

On the main board there is a room thermostat block with 2 points which have a 1 wire loop.

on the thermostat there are 5 points SL(off), live in SL (on) Neutral and live, both lives are linked.

Please could someone help, i have had my cousin (an electrician) around but he has not done one, but did explain how i should do it...but i am still confused....he did check with a meter on the points in the boiler and said it could be volt free.

Please help me....i am usually ok with things like this but this has me stumped. :(

remove the loop from the boiler terminal block.Place a mains tester to the terminal blcl and find out which one is live.The live terminal goes to Live in common on the receiver. The other teminal on the boiler terminal block goes to SL(com). Then also connect a strapping wire to the neutrals
