Central room temperature controller for ERR underfloor heating

Hello,

is there a way to control the ERR centrally on one device, so that, for example, the children cannot turn the controller of the underfloor heating (heating circuit)? In addition, I can also do without a thermostat with a controller in each room, what would be the alternative? Are there pure sensors that, for example, transmit the temperature to the control unit via radio, or does a separate fixed setting for the respective heating circuit also count as ERR?

Best regards
M

Hello,

which heating system is available? Gas? Heat pump?

Regards

Air-water heat pump: Vaillant flexcoCompact (underfloor heating + hot water)

edit: as far as I can see (e.g. KaMo), you would additionally need a control distributor for wireless.

What does your heating engineer say? There are many possibilities with Vaillant from the start.

Decommission err and set temperature via heating curve.

I have an appointment with Vaillant on Thursday.

: I would like to have this particular issue explained in more detail "disable ERR"
if the room thermostat is set to 25 degrees, but the heating itself is set to 21 degrees, then everything runs at 21 degrees. Did I understand that roughly correctly?
