Honeywell st699 issues?

[granthathaway]

Hi,

I have a query regarding the st699 controller in my property and am after some help/advice/guidance as to what to do etc.

1. the clock/timer goes wrong - after correcting it it goes out again after a couple of days?

2. my biggest concern is that, at present, both central heating (as it's summer) and hot water are off - i've never actually turned the hot water slider on since moving in in 2013!, yet i get still get hot water for a bath. I can only assume that the controller is wired up wrong? My gas consumption is extremely high over the summer months and nothing else in the property uses gas apart from the central heating/hot water???

3. How do you identify what type of system you have? I know i have a condensing boiler, with a cylinder in the airing cupboard and expansion tank in the attic.

Any help would be much appreciated.

We are skilled in the use of the Mk II Crystal Ball.

But if you only gave us a little information and perhaps some photos then we could tell you will greater certainty.

Crystal Ball images are always a little cloudy.

If you have a back up electric immersion, this could be switched on. A rather expensive way to heat your water for the last 3 years...

How many cubic metres a day in summer?

What colour is your hot-water cyinder?

Some photos would be nice.
