Noticed this am that target temp is 21.5 but heating still on at position 2 and temp 22.1.
wired connection. I also waited for 10 mins to see if did turn itself off but no...
seems like something wrong
A relay control would only allow a precission of +/-0.5ºC, that can be increased if there's a call for heating for a long period, so this screenshot can be a pretty normal behavior. If your boiler is not a relay system, please contact our tech support with the details of the date and times in which you have experienced something like this.
Many thanks fro your reply.
could you define for me the meaning of 'relay system'
This heating over- run is a new thing. Its also noticeable how the boiler demand by tado was not 1 out of three but 2 out of three,
