Radiator thermostats not in sync in the same room

TalkingTado

Hi,
I have had a Tado extension kit and a room thermostat for years and it works well. I have recently added some Tado basic radiator thermostats. I have rooms set up with multiple rads. For example the bedroom has 3 radiators, each with a tado basic thermostat. One of them is used as the main thermostat for the room.

The problem I have is that the ‘main’ radiator turns off when up to temperature (as expected) but the others do not. I expected them all to work synchronously. I could probably get them to work if I set them up as individual rooms but that doesn’t sound like a good option (I would have tons of rooms).

Any ideas what I have configured wrong?

Any help much appreciated.

If they’re all in the same room on the app then there should be one measuring device. Is the zone controller set?

Hi Johnny78,

Thanks for replying. The one measuring device is one of the rads. The zone controller is the extension kit (one zone for the whole house). I tried removing the zone controller but it didn’t seem to help. The measuring device seems to turn on and off as expected but not the other 2 rads :-(.

Am I right in assuming the 3 rads should turn on and off in sync? One shouldn’t be freezing cold (measuring rad) while the other 2 are piping hot?

Cheers

They should be working in sync. Try swapping the trv heads. If the problem moves with them it’s the heads. If it doesn’t it’s the radiators.

Presumably you’ve set one of the TRVs as the “measuring device” for that room?

Hi all,

thanks for the suggestions. It seems to be working as expected now. It was a mixture of things which resolved in the end:

• remove spanner symbol on one of the heads (disconnect/reconnect)
• bleeding a radiator !
• restart internet bridge

Think that was about it but the rads appear to be in sync now.

Thanks again

Tony
