To decide which rooms should be equipped with an Alea vent, it is important to consider that when a vent’s flow is reduced:
• The airflow into the room is decreased (we call this “direct” effect”)
• Airflow increases in adjacent rooms connected to the same duct (we call this “indirect” effect”).
If you have a “trouble-room” you need to determine whether the room is:
1.) Getting too much hot or cold air -- In which case you need an Alea vent in that room. (see diagram)
2.) Not getting enough air -- In which case placing Alea in adjacent rooms that might get too much air will allow Alea to direct air to the room(s) with more air demand. (see diagram)
In addition, you need also to consider that the same rooms can suffer from “too hot” at some time of the day or of the year and inversely from “too” cold” at other times.
Our recommendation is thus that you install Alea vents in the “trouble” rooms and the adjacent ones and enable the system to determine and automatically manage year round the best configuration to meet your preferences.
