siemens rdh 10rf wireless room stat

sorry lads another room stat problem. i got a siemens wireless room stat for my place but i cannot wire it up correctly. i've followed the sparse instructions but i don't know whats wrong, i thought the wiring centre might be duff so i wired the old stat up and it works perfectly with no problems. but when i wire up the wireless receiver the three way spins round to make on the microswitch and kicks the heating on even when off on the programmer. i guess it could be faulty i suppose.

Think you could well have a faulty one steve,not the most reliable,if you have tried reseting it,maybe relay stuck,perhaps exchange for a different brand
imho

It is more than likely wired incorrect. LX is common, if you have voltage there when the timer is off it is wired incorrect for the system as the LX L1 and L2 terminals are volt free so cannot switch a voltage. Check your wiring
