During installation, your heating contractor will determine which heating circuits
are to be controlled by the MEC2 programming unit. These heating circuits will

simultaneously:
– Setting the room temperature

If you have selected an individual heating circuit that is assigned to the MEC2,
and you want to make one of the above adjustments, the fault message
