can anyone tell me if i'am doing something wrong. I've wired a salus rt500rf wireless room theromstat to a baxi 80 he boiler and just can't get it to fire when calling for heating. It doze have the opational internal mechinical timer fitted. I've taken the link out of terminal 1&2 and taken a feed from 1 to the common of the no volts of the stat, then a switch live to terminal 2.and I tried unplugging the internal timer AND keeping plugged in on constant but still it just will not bloody fire I'm I missing some thing?

Please leave these instructions with the user
have a look at page 37/38, it has a wiring diagram and fault finding guide, it may help, i'm more experienced with oil, so don't have an answer of the top of my head.

Cheers for the reply pmac10 it turns out it might be the pressure switch at fault.
