Just bought a wired thermostat from amazon UK after I learned that the 2021 amazon wireless version I have used on previous boiler doesn't work on opentherm.

Question 1.

Wherre can I get the instructions for wiring via opentherm with the tado and above boiler.

Question 2.

Will I be able to use old bridge and wireless smart thermostat with new wired thermostat? Aim to add trvs also? Will one system accept others

Question 3.
Can I control hot water temp via tado after this install?

    1. You’ll get instructions via the app when you do the install. Make sure Tado supports your boiler’s digital protocol first, especially if it’s ebus rather than opentherm.

    2. Yes, all recent Tado devices work together.

    3. Yes, in theory. You might find your boiler controls override the temperature set in the Tado app.

    I know you’ve said your boiler is a combi but for anybody else’s reference if your boiler is a system/ heat only (with hot water cylinder) or your house is zoned you cannot use a digital connection with Tado.
