ᐅ Central room temperature controller for the fan coil unit (FCU) of the underfloor heating system

Hello,

Is there a way to control the ERR centrally on one device, so that, for example, the children cannot adjust the underfloor heating control (heating circuit)? Also, I don’t mind not having a thermostat with a controller in every room. What would be the alternative? Are there sensor-only devices that, for example, send the temperature wirelessly to the central unit, or does a separate fixed setting for the respective heating circuit also count as an ERR?

Good luck

I wanted to express that it would be possible to create a "temporary" energy reference value (ERR) using very simple means, if required.

Maybe I wasn't clear enough, because that is exactly what is planned.

Very lively and informative thread.

My main starting point was that I wanted to know which wireless thermostats and control technology you would recommend or currently use for ERR (which, according to regulations, must be installed).

The background is that if I disconnect the ERR, I wouldn’t install the unnecessary and unattractive room thermostats at all, but could reactivate the ERR if needed.

For example, Homematic IP (as a thermostat but also an actuator).

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

Does anyone know about the underfloor heating control system from Controme?

Here, temperature sensors are installed directly on the return flow at the heating manifold for immediate temperature feedback. Would this allow me to skip having a thermostat in the room itself?

This is what you do when you don't follow unrealistic regulations but know your way around heating systems and understand what needs to be done.

Remove the ERR, add return flow monitoring. Hydraulic and thermal balancing.

So, you don't necessarily have to be familiar with the control system you mentioned. This approach has been around for a long time and has always worked perfectly.

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