Where do I connect a kitchen hood (type E) and a humidity sensor?

A type E kitchen hood and a humidity sensor are connected via a three-core cable located on the top of the airhandling unit. Look for a black cable with three conductors. The brown and white conductors are used to activate the boost function, while the third conductor is normally not used. When contact is established between the brown and white wires, the unit will automatically switch to boost mode. This is typically used during cooking or when humidity levels are high. If you are an end user and not comfortable performing the connection yourself, we recommend contacting the service company that installed the system or the retailer where the product was purchased.
