Optional Lifebreath Dehumidistat - Part #99-DH01
Key Features:
 The Dehumidistat measures the indoor humidity
level and will initiate high speed ventilation when
the moisture level in the building exceeds the set
point on the control.
 Once the humidity in the building is reduced, the
HRV will revert back to its previous setting.
 The Dehumidistat should be set to OFF for all sea-
son except the heating season.
 Connect to 3 wire 20 gauge low voltage wire.
Humidity Control
Your HRV will produce a dehumidifying effect when
outdoor humidity levels are lower than indoor humidity
levels. Never use the Dehumidistat feature when out-
door temperatures are above 59 F (15 C).
Note: The indoor humidity level is measured at the
control.
Setting the Dehumidistat
Press and release the Dehumidistat button until the
Dehumidistat Light is at the desired setting. After 5
seconds the Dehumidistat light will either flash or be on
continuous.
A flashing light indicates the humidity level is higher
than the setting and the unit is operating on high
speed ventilation. A continuous light indicates the hu-
midity level is lower than the setting. Refer to the unit's
Operation & Installation Manual for instructions on how
the Dehumidistat works.
Note - Only 1 Dehumidistat should be active on a sys-
tem.
