Since it is generally assigned to heating, how and where it is connected, what it does, what it turns on or off - we don't know that and you don't write anything about it.

Not knowing the exact model of the regulator / controller / thermostat, I offered a solution for controlling the floor heating at the bottom. If it is an ordinary on / off thermostat, it can only turn on / off the pump on the OP at the set temperature in the room where it is to be hung. From the photos it is difficult to say what this regulator is, because I do not know Siemens, but you can see that it has a button with a tap for DHW, so maybe you have a more complex regulator that connects to some central unit and maybe, in addition to controlling the CO, it also controls DHW, so it will not be possible to shift it down, or it will not be possible to use it only to control the OP

Well, unfortunately, such a solution has not yet been invented for the hydraulic system you have installed. It is a system with constant water temperature in OP pipes. warm floor. For you, a solution that gives some comfort would be to set one water temperature and control on / off or the pump, i.e. the entire OP system or individual circuits, i.e. individual rooms.
In the first case, one thermostat on the wall (wired or wireless) is enough, which will turn on / off the pump (entire OP) depending on the set temperature.
In the second case, you need as many thermostats as the rooms you want to control, plus as many thermal actuators for the loops that you want to control, and a control strip for the appropriate number of heating zones.
Of course, the best regulation is the weather regulation, which changes the water temperature in the OP depending on the outside temperature. When it gets colder, the water increases the temperature, and when it gets warmer, the water temperature decreases. But it would take the entire hydraulic system to be able to use a 3-way valve with an actuator + regulator with an external temperature sensor + cable pulling etc. There is also a wireless system, but unfortunately the price can be economically unjustified.
