Which boiler do I have

[keggy]

Hello,
I am looking to replace my ch / hw programmer, while looking at the Honeywell diagrams for replacement programmers there is a note regarding wiring methods if the boiler has pump over-run,, how would I find this out. I've looked at my boiler but it just says warmflow. It has a riello rdb burner but can't find any other info.

I am having problems with my hw/ch system as the pump continues to run for hours some times, I believe my system is an s plan as there are 2x 2port valves next to the hw storage tank and the pump is also located there.

There maybe a problem with one of my valves keeping the pump running but I definitely have a problem with the controller because it will only work without the battery in the back of it!!

My system is a sealed type and the boiler has a plate on it that says its suitable for this system.

Any advice would be appreciated...

Thankyou.

Generally speaking oil boilers don't have a pump overrun so you don't need to worry about that

Great thanks, I suppose any 2 channel programmer will do !

Mine is a Honeywell st7100..
