Note: This product uses an occupancy sensor. It operates at the selected low airflow speed continuously and will automati- cally increase to the set high speed when the product de- tects motion. After the set time, the product returns to the selected low speed airflow.
This feature sets the speed of the product’s airflow to the low Operation airflow speed and holds the low airflow speed continuously if switch I is set to the ON position, if switch II is set to the OFF To Start the Product position, if relative humidity is below the set level, and if the oc- cupancy sensor does not detect motion.
Condition 2 – If the time delay knob is set in the OFF (OFF–5 minutes) position and if the humidity sensor knob is set be- tween 30–80%, the product will return to the low airflow speed in 5 minutes. Condition 3 – If the time delay knob is set between 5–60 mi- nutes and if the humidity sensor knob is set between 30–80%, the product will return to the low airflow speed in 5–60 minutes.
