How Do The Heat Level Requests Work?

Does Tado really have that much control over the boiler to request what temperature the water is each time it calls for heat?

Tado says there are 3 different levels of heat that it asks for (the 3 wavy lines) just wondering in reality if this is actually true?

  • I understand only if using a digital interface. If it is a relay Tado can only turn the boiler on or off. I'd also be interested to know what this means in a relay context.

  • I believe the lines indicate how much the TRV is opened and not the water temp in the system

    I think most water based CH boilers just heat the water to a temp set by the boiler stat e.g. 80C
  • @tulloch, a relay is IO. Doesn’t get much more interesting than that.
  • Could someone explain how the heat request works. The significance of the wavy lines and how the boiler response to these lines, I always thought it was full on or full off.

    Also could you explain the full names of the things your talking about TRV and IO for example don't mean much to me.
