Central room temperature controller for ERR underfloor heating

I wanted to express that with very simple means one could "temporarily" generate an ERR if it were required.

I wanted to express that with very simple means one could create an ERR "temporarily" if it were required.

Perhaps I was unclear, because that is exactly what is planned.

very lively and informative thread.

the actual starting point for me was that I would have liked to know which wireless thermostats and which control technology you can recommend for [ERR] (which, according to regulations, must be installed) and possibly have in use.

The background is that if I disconnect the [ERR], I do not install or fit the useless and unattractive room thermostats in the first place but could reactivate the [ERR] if necessary.

For example, Homatic IP (both as thermostat and actuator)

The cheapest possible, why should one throw more money out the window than necessary?

Does anyone know the underfloor heating control from Controme?

Here, temperature sensors are mounted directly on the return flow at the HKV for direct feedback of the temperature. Would I save myself a thermostat in the room with this?

This is what you do when you do not follow the unrealistic regulations but know about heating systems and know what to do.

ERR out, return flow monitoring in. Hydraulic and thermal balancing.

So you don't need to know the control system you mentioned. This approach is old and has always worked wonderfully.

The mentioned manufacturer is just taking it to the extreme (not necessarily required for a surface heating system).
