I have recently moved into a house that has a Worcester 30HE Combi, a built in programmer and TRV's on all radiators except 1 (but there's no room thermostat). The boiler manual says to fit a TR2.
I bought TR2, looked at the instructions that say fit 3 wires to terminals F, 3, & 4 on thermostat to terminals F, 3 & 4 on boiler, unfortunately my boiler doesn't have terminals F,3,4.
Boiler manual says to fit a TR2 with wires going to Ns, Ls, & Lr. Ns is Neutral, Ls is live, Lr is switched (but here's where the confusion lies - the diagram doesnt say which terminals F, 3 & 4 on thermostat correspond to. At a guess i'd say F goes to neutral, 3 goes to Ls and 4 goes to Lr - but thats a guess - has anyone wired one of these up before and if so would you know if what I propose is correct.
thanks in advance for any help
