If the level of humidity falls too low in the winter months while operating in the continuous exchange mode, a humidifier may be integrated into the system. Intermittent
exchange mode may also be selected for short periods of time to increase the level of humidity.

VI. HUMIDITY SELECTOR
The humidity selector is a built-in dehumidistat designed to
properly control the level of humidity in the house during the
winter months. This control helps avoid condensation problems in
upper northern regions where indoor humidity is a problem during
the winter season.
NOTE: This control is not to be confused with a dehumidistat
used during the summer months to control high relative indoor
humidity.
Table 4 recommends humidity levels to avoid condensation.
