The Viessmann Vitotrol 100 was discontinued in 2018 but was (and still is) a very good hard wired OpenTherm Thermostat. It had the ability to weather compensate any Viessmann boiler with an outside sensor fitted, and has 40 weather compensation curves you can select.
The Viessmann Vitotrol 100 was made by Honeywell and this thermostat is what is known as a CM737 which is essentially a hard wired OpenTherm modulation thermostat.
I believe it will work with any OpenTherm Boiler (Intergas, Alpha, Viessmann, Atag, Baxi & Ideal) as it has the ability to set the maximum heating flow temperature and hot water temperature.
