Hi,
I'm hoping you can solve my wiring problem. Just bought a Drayton +2RF wireless Thermostat which I am trying to fit to my existing Worcester 28cdi combi boiler.
The bolier was original fitted with a 24hr clock/timer, on/auto/off with three wires which i have now disconnected from the boiler. I have tried to wire the new wireless thermostat to the instructions. The wireless controller is connecting to the receiver, the red light flashes saying they are communicating & the boiler fires up. However, I find when I no longer need to heat the room up, by switching the controller completely off, the pump continues to run on, & heating as required ( with the old clock/timer, the pump ran on , but then it stops completely) I have turned off the freeze protection in the clock
The boiler has four connections NS / LS / LR / Spare
The wireless unit has N L 1(common) 2(heating satisfied or call for cooling) 3(Call for heat)
I have wired it as follows: N to Neutral (switched 3A)
L to Live (switched 3A)
1 loops 2
2 loops 3
1 to LR
3 to LS
Firstly I need to know if I have wired this correctly
Secondly do I need to wire up the original 24hr clock to switch off the pump completely and if so, how?
hope this makes sense
Thanks
