hi guys my gran parents got a new combi boiler installed yesterday installers left just left the roomstat sitting for them to setup was late last night that i had a chance to even look near the programmer cm727 when i noticed the roomstat was not communicating with the boiler ie when you turn the stat to off the boiler still demands heat ended up having to turn the c/h temp down to off
phoned the installer to see if he can sort the problem out but can't get out for 2 weeks an said that a electrician installed the stat an receiver relay an he's away on holidays today for 2 weeks
stat an receiver is binded an transmits through out the house even when demand for heat on the stat shows flame an green light on the receiver heating doesnt want to come on
the 2 black switch wires (A & B) to the ebus are connected but on the receiver(relay) N,L,L there is 2 brown wires in the middle L is that right an no wires in no.2 L
