iCOM Control Training and Service Manual

If the off time is less than 15 hours (or user programmed value) the pre-fill program is bypassed and the infrared lamps and water valve are activated at the same time to fill the pan to the proper water level and initiate humidification.

During normal infrared humidification operation the water makeup valve is periodically closed (no pan fill) and opened (pan fill) based on a timing sequence to allow for the evaporation of water from the pan (see flow chart below).

With the humidifier water flush rate set at the factory default value of 150% the water makeup valve will open for 7 minutes of fill time with an off time of 45 seconds between fill cycles for a small pan. For a large pan water makeup valve will open for 10 minutes of fill time with an off time of 80 seconds between fill cycles. The user can modify the percentage from 110% to a maximum of 500% in 1% increments.
