Important: As of Release 5.1, the Humidification Scrubber Output v51 module replaces the Humidification Scrubber Output v50 module.

The Humidification Scrubber Output module controls a scrubber that provides humidification. A scrubber is a two-position humidification device. The basin fills and the pump runs when humidification is required. If the pump is off for a user-defined period of time, the fill line closes and the basin drains. This module also incorporates tracking the overridden value of the actual output object (AO, PAO). The module resets the PIDs to default tuning parameters if the Reset PID Tuning input is not Normal.

This module provides a second output that incorporates lead compensation to control devices. This function attempts to remove some of the dynamics of the control loop. This process results in forward-looking predictions and speeds up controller responses. The effect is similar to adding derivative action to the controller. Lead compensation is incorporated into most zone temperature control processes where oversized or nonlinear valves might be applied. For more information on the Lead Compensator block, see Lead Compensator in the Control category of the Logic section.
