I have got an old Servowarm boiler (elite 50) and the pump went on it.
I have replaced the pump and have noticed that a bi-metallic strip wa broken in the timeclock( beleived to be old horstmann emerald)
I have got an electrician to install a new Drayton LP241 programme along with a seperate timer for the pump overrun.
All works fine except that from the boiler control drayton show 3 wire coming from the control to the programmer (Live Neutral and earth) bu mine has 4 wires from the control (Live Neutral Earth and a Red wire)
My electrician has wired the Blue to Blue on Programmer terminal, Eart to the earth and the red to position 4 on the terminal block but th live is not connected.
Can anyone tell me if this is correct and if not which wires go where?
I have no room stat or auto valve for hot water.
Each radiator has a stat and the CH/Hot water valve is manual.
Thank
