I have an Apollo Fanfare with boiler overrun, there is two cables coming from it, one has three wires which I presume is power the other has two wires one is blue the other is brown, this I think is the power to the pump, I have fitted the following.. Drayton Lifestyle LP522 programmer Drayton Mid position valve, Drayton LWC1 junction box, Drayton Digistat 1 Room thermostat, Pump Cylinder thermostat. When I switch on all seems ok, but when I try to switch the central heating off with the programmer, there is no response from the boiler, when I switch the hot water off using the programmer the boiler switches off then restarts. I wired the system as per info sheet from Drayton ie Biflo with LWC1 and pump overrun boiler from there website. Please help if you can. Thank you.
