as i said there's two boilers this thorn and another one for the hot water i saw it last year when they moved in. if i recall correctly there is a pump under the thorn. the hot water boiler has replaced the cylinder i think it is a hot water only combi as there is only cwsc in loft.

so the appolo drives the heating and a multipoint geyser type boiler does the hot water? now thats weird the apolo could drive a cylinder what a rubbish way to fit a system in that case steve you just need a basic single channel clock

it looks like the other boiler is mounted where the cylinder used to be one side of the window in a bedroom and the other thorn on the other side of the window in the same room.

been today to fit the new timer. got a horstmann centaurplus c17 in the end. have tried wiring it up but came to a dead end can anyone help please. which set of wires do i connect to, there are three pump, live to boiler and thermostat i think. in the apollo wiring diagram it says if fitting an external controller to remove a link between hw and on had a look but there isn't one i could see.

if the existing clock works on continous you can leave it in situ
wire the new clockwith a live and neutral to the motor and use the clock switch to break the wire to the switch live on boiler this is assuming that the boiler is purely doing heating and needs a time switch rather than a programmer

 

[PlumbBobBob]

yes heating only

ignore the thermostat in the drawing steve

live from boiler or anywhere else its common on the boiler circuit then intercept the switched live wire one end into the boiler S/L and into clock the other from the other terminal on the boiler into the clock you will have to trace what goes where on the boiler but basically your making a switch mains in, live in live out
