Dehumidistat Control
Only the DXPL02, BC02 and BC03 controls have an adjustable Dehumidistat.
ERV's are not Dehumidifiers but may have a dehumidifying effect on the ventilation air only. This
greatly depends on climate, heating/cooling system being operated in the home and lifestyles
of the occupants.
NOTE: The dehumidifying feature will not work when the outside air is above 15°C (59°F)
therefore, this function is automatically disabled.
Homes in northern climates may experience high indoor humidity levels during the heating season.
This can become a problem in many well insulated, tight homes. Excessive condensation on the
windows is an indication of poor indoor air quality. This can result in mold and mildew and the
eventual degradation of the building structure itself.
Your ERV may reduce indoor humidity levels when the outdoor air is drier than the indoor air.
These conditions usually occur during the heating season when outdoor temperatures are less
o
than 15°C (59 F).
The DXPL02, BC02 and BC03 controls have an adjustable Dehumidistat which when activated
jumps the ERV to high speed ventilation. Once the humidity in the house is reduced, the ERV will
revert back to its previous speed or setting.
We suggest operating the ERV for the first few days without use of the Dehumidistat function to
observe if a further dehumidification effect will be required. The Dehumidistat operates in % of RH
(relative humidity) with 60 being high and 20 being low. If after a few winter days, further
dehumidification is required (the house is still too humid), set the humidity level to a lower
amount. The average person is comfortable between 30% and 50% RH. Refer to the "Setting the
Dehumidistat" section of either the DXPL02, BC02 or BC03 control instructions on how to set the
Dehumidistat, depending on which control you have installed.
Dehumidistat Notes
Dehumidistat Disable automatically disables the dehumidistat function on the main control when outdoor

temperatures exceed 15°C (59
while the dehumidistat function is disabled.
Dehumidistat Re-Enable automatically re-enables the dehumidistat function if either the outdoor temperature

drops below 15°C (59
o
F) for a full 24 hour period. All other ERV features and functions operate normally
o
F) for a full 24 hour period or if the ERV is reset (unplugged for 30 seconds).
