Has anyone got the Honeywell wiring booklet/guide? I downloaded it.
The wiring for a S PLAN with pump overrun doesn't make sense, the reason I say it is :
the boiler has a NEUTRAL and EARTH connection as normal, a PERMANENT LIVE to it, and still has the switched live from the ORANGE WIRES to it. The boiler provides LIVE to the PUMP via a separate terminal block. My point is: how does the pump run?
Pump overrun stats make when the temp is over 60 degrees C and open when the temp is under, so when the boiler 1st starts up, and the water is a lot lower, does the pump not run ??? .....
