If you are experience condensation or increased mould in your home simply 'op' the settings on your Ventis.
We recommend the following settings
Heating & Cooling on
Fan on Circ3 or Boost High
Set point 22
Ventilation on
Drying mode off (if its on your version of controller)
And also utilise the flush or ON mode morning & night when you are leaving the house, this will force the system to run for 2 hours while you are not home. And give your home extra airflow.
