Please, can anyone tell me why?

So I'm fine tuning my heating, and set my lounge to begin heating if the temperature falls below 16 degrees.

I'm sitting here, it's 16.6 and warm enough for me right now, but the tado wired thermostat just turned on the heating.

Why please?

    If the temperature in the room is falling, Tado will turn the heating on to stop it dropping below the set temperature. If it waited until the temperature fell below 16 before turning on the heating, it might continue to fall for a while leading to larger temperature variations. For most of my rooms, Tado will hold the temperature with +/- 0.1 degrees, but I think it helps that mine it set up using Opentherm, so it's not just turning the boiler on and off, but able to adjust the flow temperature as necessary.

  • The odd thing is neither the temperature outside, nor the room temperature was rising or falling. I had to manually turn the "room" off to stop the boiler from its short-cycling episode and wasting oil (firing the boiler for 20 seconds before turning it off).

    I'm trying everything, but everything I try results in a colder house and more oil usage than the manual system I had before.

    I would forego this preciseness for a wider variance of temperature if only the system would stop short-cycling my boiler.

    I suspect the default Tado logic is calibrated for more typical (in Europe) gas boilers. You might be able to chat with Tado support, as they have hidden settings to tweak that might improve your operation such as increasing the minimum firing time
