installing a honeywell st699 timer

[NIGHTFLIGHT]

i have taken out an old unknown make timer and want to replace it with this unit but can't work it out. i have a power cable from a fused socket and then a four wire cable connected to the boiler.
anyone any ideas ??

NIGHTFLIGHT - This is really freaky! Sorry, I have'nt the answer to your question but, I was only looking at honeywell timers/thermostats? the other day on ebay. We have been decorating and I was looking at our old honeywell thermostat thinking I would like to update it before putting up new wallpaper. We bought our council house about 3 years ago and we have had this old thing on the wall since first moving in! I don't even know what model number it is and what would be its equivelant? Your timer/thermostat sounds the same as what we have. I will keepan eye on your post xxx

thanks - beware - it looks tricky !

what type of boiler is it .e. combi boiler, old style boiler with cylinders and tanks etc.
and in most cases you can swop the head of the programmer for a new one and leave the backplate and wires in place. i would take the head off, take it to your local plumbers merchants and ask them for a compatible one
