The HR Low Limit Sequencer module manages a heat recovery device and activates an alternative control mode if the low limit process variable falls below the low limit setpoint. This module could be used with either a glycol loop or an energy wheel to prevent the exhaust temperature from dropping below the low limit setpoint. This module accepts inputs for the limit temperature and setpoint, and the heat recovery output controller control status. The module has an output for the state. For information on how the FSM determines the state, see FSM (Hx Sequencing).
