RT-Series Typical Applications Exhaust COP (XCOP1) Draft COP (DCOP1) 1) Intercepted call for heat activates Draft COP. Triggered by an external switch or constantly operating, the Exhaust COP maintains a negative exhaust pressure set point by modulating the speed of the Rooftop Inducer to meet demand. 2) Draft is measured and compared to set point. 3) Inducer ramps up to meet draft set point. 4) PSA-1 fan prover closes enabling burner call circuit.
