Problem with multiple valve associations

Hi i have a problem with the association of 3 valves to a wall-thermostat.

The first one in the association declaration (htWohnzimmerPosition.mean) works as intended …ure=temperature:associate=MEQ1818437,MEQ1818441,MEQ1818489

The other two get their temp obviously not from the wall thermostat

Set Point for wall-thermostat is 20.5°

(Big Windows & the sun is shining)

are there some hints for me ?
