Some models have a built-in dehumidistat (an optional
remote wall mount dehumidistat can be installed, see
Optional Remote Controls), to control harmful, excess
humidity during the heating season. The dehumidis-
tat operates in % of RH (relative humidity) with 80
being high and 20 being low. The average person is
comfortable between 30-50%.
The dehumidistat will override the ventilator to high
speed when the moisture level in the home exceeds
the set point on the control. Once the humidity in the
house is reduced, the HRV/ERV will revert back to its
previous setting.The dehumidistat should be set to off
for all seasons except the heating season.
Note: If your HRV/ERV is equipped with an internal
and an external dehumidistat, the internal one can be
turned off and not used.
