TADO works as a Relay System or Modulating?
I have a Logic combi esp1 35 boiler which was controlled by a Danfoss tp5001 wired thermostat. The thermostat had only two wires, COM and NO. Its manual states it is an "On/Off load compensation thermostat". The boiler has a "Fully modulating operation to low outputs" (from the manual). The manuals state that both boiler and Tado support OpenTherm.
I replaced Danfoss with a Tado v3+ wired thermostat.
Is Tado, based on the heat request, able to modulate the heat the boiler supplies in order to reach and maintain a specific temperature or works as a relay system, where the heating system turns on (100%) or off (0%) completely for specific time cycles based on the heat request?
