Residential HRV/ERV
16
Your HRV/ERV will reduce indoor humidity levels when outdoor air is drier than indoor air.
This usually occurs during the heating season when outdoor temperatures are less than 10°C
(50°F), as shown in the following table:
RECOMMENDED RELATIVE HUMIDITY TO PREVENT INDOOR CONDENSATION*
OUTSIDE AIR TEMPERATURE RELATIVE HUMIDITY
0°C to 10°C (32°F to 50°F) 45% - 50%
-6°C to 0°C (21°F to 32°F) 40% - 45%
-12°C to -6°C (10°F to 21°F) 35% - 40%
-18°C to -12°C (0°F to 10°F) 25% - 30%
-24°C to -18°C (-11°F to 0°F) 20% - 25%
Under -24°C (-11°F) Under 20%
*Values according to the type of construction and fenestration of your house.
ASHRAE 62.2 standards recommend maintaining a relative humidity rate between 30%
and 60%. The average person is comfortable between 30-50% relative humidity (RH).
Aldes oers several wall controls with a dehumidistat function. Please refer to the wall control
user guide for detailed information.
