Maybe if it has the same code set on those DIPs. And since their number is limited, it is possible in blocks of flats where many people can have the same regulators.
That's why I bought myself an RT510RF with digital pairing and the problem of settings on the switches does not concern me.

In fact, you can use the so-called night temperature reduction, although it does not necessarily have to be used only at night, it is your choice how you use this option.
I use a round-the-clock temperature, because I have an old building, so night reduction with my current installation does not make sense, because it is hard to heat up afterwards.

Drop tolerance is what you mean. hysteresis.
In this regulator, the factory hysteresis is 1.0 degrees, and it can be changed to 0.5 degrees.
What does it mean.
If you set the regulator to 20.0 degrees, then with a hysteresis of 1.0 degrees, the regulator works like this:
When the temperature on the controller drops to 19.5, it turns on the heating and maintains the heating demand until the temperature rises by 1 degree, i.e. to 20.5. When it reaches 20.5, the regulator turns off the heating and waits until the temperature drops back to 19.5 and the cycle starts again and repeats over and over again.
Now, it depends on the adjustment of the boiler and the installation, whether heating by this 1 degree will be as part of one burner operation cycle on the boiler, or rather, due to the boiler's oversize, the burner will clock more or less until reaching the 20.5 degrees in the room.
If you set the hysteresis to 0.5 degrees, it will be the same as above, but with 20.0, the heating will be turned on, for example, at 19.7, and turned off after increasing the temperature by 0.5 degrees, i.e. at 20.2.
If you do not have the manual, download it from the manufacturer's website and you will know how to program this regulator. You need to practice and choose the optimal variant of settings for your premises and your needs.
