Honeywell ST799 timer for gas central heating

[nickh1964]

Dear All.

Help please...the timer we have has stopped working. The clocks still working but the redlights which indicate either the waters heating or the central heating is running are not coming on when the bars to turn both on are slid over.

Added to this the thermostat which runs off this does not click when rotated so it appears there is no power getting to it.

As the lights on the ST799 are not working is there a seperate fuse for this somewhere. Any help would be appreciated before I call someone out.

Thanks

Without being at your property or having a full interconnection schematic, I don't see how we can give you any advice.

It will be a very simple task to diagnose for anyone who has electronics experience!

But it does need testing with a meter!
