Important: As of Release 5.1, the Zone Damper w Proportional Heating Valve v51 module replaces the Zone Damper w Proportional Heating Valve v50 module.

This module sequences the control of the zone dampers on a multizone unit with a proportional heating valve. 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. You can view and modify the modules in this group’s logic.

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.

For information on how the FSM determines the state, see FSM (Texas Multizone Sequencing).
