Hi all,

I was wondering if anyone had an idea of how the control of DHW works on the Ideal pre-plumbed cylinder (I also have a Halo Thermostat). I think I've located the correct setting in the installer parameters, 1620 - Release, which is currently set to '24 h/day'. My understanding of how this is working is that whenever the water temperature drops below my set point, it will switch on and heat the water back to 50 degrees.
This has led to it coming on in the evenings after washing up or running a bath for the kids, which is not ideal as at that point I won't need hot water again until the following day and if it's before 7pm it's costing me 40p/KWh!!

I would much rather it heat the tank between 1-4pm when we're on the cheapest rate and we have the sun to help us out, but when I've switched the hot water to timed on the Halo thermostat, it seemed to just ignore the settings and come on when it wanted.

The options under the installer parameters are:
- 24 h/day
- All time programs HC/CC
- Time program 4/DHW
- Low-tariff
- T'prog 4/DHW or low-tariff

It's not clear in the manual what any of them do, so if anyone has any idea of how I acheive what I'm after or if there is a document somewhere that spells out what the different settings actually mean I would be incredibly grateful!

Also, if anyone is aware of how to select the time the legionella cycle runs, that would be nice too, currently it runs once a week but I can't figure out how to specify when!

TIA
