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 unit will revert to
its previous setting.
• The Dehumidistat should be set to OFF for all season 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 outdoor 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 humidity level is lower than the setting. Connect to 3 wire
20 gauge low voltage wire. Mounts in a standard 2” x 4” electrical box.
Note - Only 1 dehumidistat should be active on a system.
