What an idiot!
I've bought a starter kit with smart room thermostat and bridge (successfully fitted) and some radiator thermostats. Being an idiot I didn't check that my existing thermostatic radiator valves were compatible with the tado ones and they're not - they're Pegler Mistral II. Will I need to have these replaced before I can install the tado smart valves? If so any suggestions as to what I should replace them with? Thanks
