Among the various CMV models, the humidity-controlled CMV is an effective solution to allow a renewal of the ambient air in the different rooms of a house, while achieving some consumption savings. If you chose this type of ventilation, here are some tips for installing a humidity-controlled CMV.
Type A or type B, the humidity-controlled VMC is based on humidity detectors placed in the return vents and the air inlets which allow the ventilation to be adapted according to the indoor humidity level. Thanks to this humidity detection, the humidity-controlled VMC allows greater savings in consumption than regular and constant ventilation.
Installation of humidity-controlled CMV
To install your humidity sensitive CMV, you will first need to position your extraction box in the attic of your home, preferably the most in the center of the different extraction vents, and suspended from the frame rather than placed on the ground, to avoid too high an operating noise level. The extraction vents will be positioned in damp rooms (toilets, kitchen, bathroom), generally under the ceiling, and connected by ducts of 80 millimeters in diameter for the toilets and the bathroom, of 125 millimeters in diameter for the kitchen. For humidity sensitive CMV, we finally advise you to opt for insulated glass wool ducts to avoid condensation.
