Your HRV/ERV system produces a dehumidifying effect when
outdoor humidity levels are lower than indoor humidity levels.
These conditions occur normally when outdoor termperatures are
below 60°F. An additional dehumidification effect is achievable
with the Optional Dehumidistat (Part DH1).
The Optional DH1 Control may be combined with the Healthy
Home System Control (HHSC). The DH1 will initiate high speed
ventilation when the moisture level in the home exceeds the set
point on the control. Once the humidity in the house is reduced,
the HRV will revert back to the HHSC automatic setting. The
Dehumidistat should be set to OFF for all seasons except the
heating season.
