Vaillant ecoTEC plus 624 Compatibility


I received a Tado Starter Kit V3+ (wireless smart thermostat, programmer with hot water control) via OVO when I switched suppliers, and wanted to know if it is compatible with my Vaillant ecoTEC plus 624 boiler, which is probably 15 years old.

I cannot find anything concrete on whether I can use my Tado with this, and if I unbox it, it cannot be returned.
