Sorry there have been many threads on this subject but i cant quit
resolve my question. I have a WB Greenstar HE combi which has its own programmer. I hav bought a simple TR2 room stat to control room temp.
Boiler manual says connect TR2 to terminals 3,4 and F (on boiler). It does not say what 3,4 and F do??
I assume i remove the link from the boiler circuit and connect the sta to 3,4 and F but the stat uses terminal 1 and 3 for L and N which i call and satisfied. Plus there is an earth connection. No obvious eart connection on the boiler where the TR2 is supposed to go?
Any ideas as any way i try it the boiler just says the link is remove
- it is not picking up the room stat
