Hello
My Honeywell programme is one of these...
I find it very annoying that it doesn't allow me to progamme the DWH and CH independently, i.e they both come on and turn off at the same time.
I wouldn't be so bothered, expect that, when they are both one, the system seems to priortise/favour the central heating over the hot water. I.E - after an hour of running, the radiators are all blasting heat, but the hot water in the tank is only luke warm, whereas it'd usually be piping hot after 20 mins without the CH on.
I've got two questions;
- I have two diverter valves, one marked Hot Water and one marked Heating. At the end of the heating valve pipe, I've a shut off valve marked 'Heating Bypass', which is closed tight. I'm wondering if I need to open this to midpoint, to bypass the CH circuit partially, and allow the DHW to get hot, even when both diverters are open?
I may have totally mis-understood what the bypass does....very grateful if anyone can shed some light!
- My other question is, I'm thinking about swapping the programme for a more modern Honeywell, like this;
Obviously with the plan that I could separate DWH and CH timings, but would the backing plate & wiring configuration be the same between these two? I don't mind some fiddling with the wiring, I just want to avoid digging out the wall.
One more thing - I can't find a thermostat in my house, anywhere (not even on the unvented cylinder!)?......is this unusual!?
Cheers!!!!
Tom
