Why is one radiator reaching much higher temperature than the one set

Hi all,

I've recently had my tado system installed and it all seems to be working fine - apart from one room which I have set to 15 degrees and yet consistently it seems to reach temperatures of 23 degrees. Any ideas why this may be happening or how to fix it please?

Thanks,

ruth

  • It sounds like the TRV head is failing to close the radiator valve. Remove the head and depress the centre pin with a coin or a metal tool. If the pin is stiff or fails to move then use a small amount of WD40 to lubricate. Could also be a calibration issue. Removing the batteries will force the TRV to re-calibrate the motor when the head is reattached.

  • Thank you so much. I will try that
