[Solved] Choice of controllers for controlling underfloor heating on the first floor and ground floor

I would like to be able to change the temperature in the rooms upstairs, in the bedroom and at the children's home. I have 2-wire cables running from the rooms to the manifold in the cupboard. What room controllers should I buy to control this nicely and to allow the controller to learn how to heat a particular room?I don't know what would be better downstairs, whether to control it with a room regulator and actuators in the cupboard or to feed the manifold with a three-way valve with an actuator and a weather controller downstairs at the same temperature and maybe connect a room regulator to control the three-way valve.Then control it with a weathervane and a room regulator.

It all depends on what your budget is. The simplest and overall best is to use a controller like this in all rooms:
Which switches on/off the individual heating loops. In addition, it is worth having a special strip at the manifold which switches off the circulation pump when all the valves are closed. The simpler it is, the fewer operational problems.

I'm not sure that controlling the underfloor(frequent)makes sense. The floor has a lot of inertia, it's not a radiator that's cold in a few (maybe a dozen) minutes after turning it off.

Believe me, it does and I know this from experience over many years of operating underfloor heating.

Something I also know about this. It takes a minimum of several hours just to heat up an underfloor heating system in the autumn so that the heat is perceptible.

Does this controller have the possibility of learning how to heat a given room? I mean, if I plan a certain temperature at a certain time, will the controller switch on at this time or much earlier, knowing how long it takes to heat up the room?

In order to optimally control the underfloor heating, we recommend setting a constant room temperature around the clock. As already mentioned, the inertia of the system is high. On the other hand, preemptive heating, i.e. automatic switching on earlier to reach the set temperature at programmed times in the case of the underfloor heating system does not make sense, because if you should not set different temperatures during the day, there is no situation when the temperature is raised from a lower level to a higher one.
Please check the Euroster 4040 controller - this model has a suitable proportional PWM algorithm which minimises the inertia of the installation, obviously in the context of maintaining one constant temperature. In other words, it ensures that the set temperature is not exceeded or undershot too much, which is the case when using hysteresis-based operation in typical room controllers. This model also has an overrun setting and you can see for yourself whether it makes sense to set it or not. Another cheaper solution, which also works well in underfloor heating, is the Euroster 4020, which is also equipped with the PWM algorithm, but does not have the option of setting programmes or heating advance.

This controller I have shown is an example. All its , "intelligence" is that it is possible to set modes and several for each day of the week.

A lot of people question the sense of using controllers with underfloor heating, hiding behind the inertia of the floor. It is true that the underfloor heating system has its own inertia and, despite appearances, this is an advantage, especially in rooms such as bathrooms. Of course, you can heat the underfloor 24 hours a day, but why If the heat source is a traditional cooker, let it heat, but if you heat with gas, it already matters, and it matters a lot. Of course, I have no intention of convincing opponents and theorists, because this is pointless. As a practitioner of many years of use (more than 10 years) with gas heating, it makes sense, especially when the gas bill comes.
It's like asking the question why regulators at radiators, after all you can control the heating temperature on a gas cooker....

Good day, I would like to regulate the temperature in the children's rooms, when they play or study during the day, the temperature will be higher, for example 22 degrees, but for sleeping it is already too much and if I heated it non-stop, it would be simply impossible to sleep. I have 19 degrees in my bedroom and the kids come to sleep like gophers so I have to reduce the temperature in the children's rooms at night.

Good morning thank you all for your help.
