Wireless Thermostat for Oil Central Heating

[Darkness]

I have a Riello Mectron 3bm burner/boiler outside and its controlled by an analogue time clock. I think its time I got a thermostat installed as its currently starting and stopping based on the water thermostat.

I have been looking for a wireless thermostat but I don't know what works with an oil burner or doesn't work. I did notic a Honeywell DT92E but all the others seem work with combi boilers so I don't know if that rules out an oil boiler.

Can anyone recommend a wireless thermostat and also anything I need to be aware off or do when installing one? I remember reading that I should turn the water thermostat on the boiler to max, is this true?

Thanks

The honeywell cm or dt ranges are the best.

You should change the cycling rate yo something more suitable for oil boilers, but this is in their manual.

I've been looking at a few Honeywell thermostats from a DT92E which states for oil and then you have the fancy CMT921.

What I notice with the CMT921 and sililar ones is that they have volt free connections, suitable for combi boilers. Can someone explain what it means by this and why its suitable for combi boilers.
