EHUMIDISTAT
Dehumidistat (99-DH01) Operation:
(1) Dehumidistat Adjust Button
(2) Dehumidistat LEDs
Press the Dehumidistat Adjust Button to set the Dehumidistat to the desired humidity
level. The Dehumidistat LEDs will indicate the set point. High speed ventilation will
initiate when the indoor moisture level exceeds the set point on the control. Once the
humidity in the house is reduced, the HRV will revert back to its previous setting.
The dehumidistat should be set to OFF for all seasons except the heating season.
