Obvious Ventilation Controls
No climate specific information applies.
Ventilation controls can sometimes look like ordinary light switches. Exhaust fan and other ventilation controls should be permanently labeled as such, unless their function is obvious or they are labeled by the manufacturer.
For more on exhaust fans controls, see Continuously Operating Ventilation and Exhaust Fans.
How to Label Ventilation Controls
- Clearly label the ventilation controls (exhaust fan switch) or install controllers that are clearly labeled by the manufacturer.
The HERS rater should inspect to ensure that ventilation controls are clearly labeled, unless their function is obvious (for example, a bathroom exhaust fan).
Whole House Ventilation
Function of ventilation controls is obvious (e.g., bathroom exhaust fan) or, if not, controls have been labeled.
- Install controls that are differentiated or labeled by the manufacturer.
- If function of ventilation controls is not obvious, install permanent labels to indicate the function of the control.
