Hi All,
Can anyone help with what wires I should connect to a new Horstmann Channel plus H27XL.

I have a gravity HW and Pumped CH system with room stat (no cylinder stat)

Here is the existing timer Horstmann Diamond

what wires control what and have had a go at replacing
View media item 26135
I have the installation instructions here but cannot work out what goes where exept for the L,N and E and I can see that I need to link L 2 & 5 which I have done. I have also removed the gravity link.

I have DHW going to 1
Room stat (yellow) going to 4
CH pump (Red) going to 5
CH Pump (Yellow) ? this is where I have a problem can not work out where to put this wire.

Try removing the link that you fitted between 2 and 5, and then put the red pump wire into 5 and the two yellows into 4.

Are you sure this system worked properly before?

Yes it was fine the only reason I replaced the timer was because the plastic lugs broke off and could not set the timer.

Ok, replace the link between 2 and 5, the red goes to 4, and the two yellows go into a piece of choc block they do not connect to the programmer.

YES that's done it thanks holmslaw, your a star all working and pump switches off when Room stat turned down.

Thank you
