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

Ask your heating installer for the cheapest solution for actuators and thermostats.
Then remove the thermostats from the wall and install a blank cover so nothing is visible anymore.
Controme is a system that claims to control the heat pump for each individual room.
If you have understood the posts here, it should be clear to you that this is not possible with a standard home installation.

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

Here, temperature sensors are mounted directly on the return flow at the heating manifold for immediate temperature feedback. Would this make a thermostat inside the room unnecessary?
Most heat pumps are controlled by the return flow, so why would you install an additional return flow control system?

Well, that is overengineering at its best.

The cheapest option available, why throw more money out the window than necessary?

For the underfloor heating actuators, I only found systems from Homematic. Actuator 190, actuators around 20 EUR, and thermostats around 45 EUR.

Does anyone know of other systems?

Thank you. Unfortunately, these are not the wireless versions. The Alpha 2 also costs around 200 EUR.
