Thank you for your question on the model 82W humidity sensing switch. When used in the CYCLE Mode, the control provides a pre-set ventilation ON Time for meeting continuous ventilation codes. After the initial ON time is set by manually turning the fan ON, the control will provide continuous activation cycles every hour. Also Sense on Rise is active in the Cycle mode, so if the control is in the "Fan OFF" portion of the cycle and it senses a rise in humidity, it will bypass the remainder of the OFF cycle and start a new ON cycle with a time duration equal to the TIME potentiometer setting.
Should you have further questions, please contact our Technical Support Department directly at 800-637-1453.
