Boiler constantly on not turning off when temp reached

Aar0n

Hello,

I have just set my Tado v3+ wireless system up to my baxi 105 he boiler and the problem I have is the central heating is constantly on.

I have capped the old thermostat as to the instructions and wired the receiver to the boiler as to the instructions. So currently I am running off my old timer system.

If I ask the Tado to heat the receiver clicks to turn central heating on but the boiler doesn’t respond.

Any help would be much appreciated

I think you may need to link out the timer on the front of the boiler

Or possibly leave the old timer on constant so it isn’t timed or off

It’s not wired correctly.

I have followed the combi boiler live linked

So on the old timer you should see to black wires going in and then two wires coming out that goes into the timer . If you turn the power off . Disconnect the two wires going into the timer and put a link in . See if that works . Just means the old timer isn’t connected anymore

All sorted turned out the receiver box was to close to the boiler which was interfering with the boiler
