i have the following boiler

http://www.tradeplumbing.co.uk/asset...IASI_BOILERS/H
E%20combi%20boilers/INSTALLATION_RIVA_COMPACT_HE_3804_EDITION.pdf

the manual states that i should connect a room thermo stats to the terminal 1 and 3.

the thermostat stat it self has more than 2 connections.

it doesn't actually say what wire should be connected to which terminal.

does any one know what those two wires are for. on the thermo stat there is L, N and eath

the boiler manual says do not connect live wires to terminals to which the room thermostat must be connected.

all it shows is a picture of a thermos stat and the two wires shoved in to terminal 3 and 1 on the connector of the boiler.

stupid boiler manual, it doesn't give clear information.
