Choosing a central heating controller

[Addlepate]

Hi all,

I need to find a central heating controller for a couple of different applications, but knowing nothing about controllers I'm not sure where to start.

1. Mother's house: she has a WB Greenstar ZB 7-28 (GC41-311-62) with an older Drayton Lifestyle LP722 controller / timer and a separate RF wireless room thermostat (RF601?). She would like a controller / thermostat where she can programme a temperature profile, so for example she can have the temperature low at night or in the middle of the day and higher morning and evening without having to turn the thermostat up and down.

2. Our house: we have almost the opposite, in that we have an Alpha E-Tec 28NX boiler with a Wolseley (Plumb Center) 340022 which appears to do a temperature profile but no on-off timing. Not sure what we want TBH but probably something that will do timer, temperature profiles and perhaps IoT / Smart.

Trouble is I don't know where to start; I don't know whether all these things work on the same system / protocol, what to look for or anything really; hoping someone could give me a few pointers to start with ...

Thanks

Pretty much any wired or wireless thermostat can be used with those boilers.
There is no protocol or system - they are an basic on/off switch. When the switch is on, the boiler works.

Some manufacturer specific controls may have features where the burner power can be adjusted relative to the temperature required, and theoretically those with Openthem can be used with controls from other manufacturers to do the same, but retrofitting such things will achieve next to nothing in savings while adding a pile of problems getting the various items to work together.

As for functionality - you already have examples of the two types available.
It's either the old style on/off timer and a separate manual thermostat
OR
it's a programmable thermostat where you set the temperatures you want at various times.

There are no programmable thermostats with on/off, as that defeats the entire point of them. For periods where you don't want heating, you just set the temperature to a low value such as 10C.

'smart' thermostats just means it connects to a phone or other devices, and the added features are primarily remote control, which is mostly irrelevant as it's unlikely people want to be controlling heating when they are not in the building - and even when in the building, a thermostat is a set once and leave it like that device, not something which needs constant adjustment.

901KT ( screwfix number ) swap existing room stat for this and leave timer on constant .
