That is beyond me. All the more so in mid-season when the solar gain but also the outside temperatures can vary greatly from one day to the next.
For my case, by default the user interface including the room sensor is incorporated into the indoor unit.
The remote user interface is an option that was not offered to me, the indoor unit being in the heated volume of the house. Then I have a thermostatic valve on each group of radiators.
Since I don't have a remote room sensor, I only have access to adjusting the water law and setpoint by time programming and that's enough for me. No interior temperature adjustment at this level and never noticed any nighttime overheating.

20°/12° gives night T°: 19,8° at 3 a.m. (= 4 hours before resumption of daytime T°).
checked manually at specified times or data automatically recorded?
