External temperature senzor on Vitopend 111 W

TheodorC — Thu, 30 Dec 2021 08:21:08 GMT

Hello,

I have a Vitopend 111 W which runs great. It is controlled by a ambient thermostat. I wanted to fit the external temperature senzor to have the boiler adjust the temperature of the heating agent according to the external temp and as specified in the manual I did. All ok up to a point:

Two questions I have:

1. The external temperature sensor for weather compensation works independent from the interior ambient thermostat?

2. It does not matter what compensation curve I select from the dial on the boiler, with the external temperature sensor fitted the boiler will always keep a 45 C temperature in the radiators. It seems it is not following the weather compensations curves and also ignores the commands from the ambient thermostat. Is there any supplementary setting I have to make to the boiler to make this work?
