Sequence of Operation:
1. Changeover/Morning Warm-up (Central AHU Heat/Cool): If supply air as measured by the discharge
air temperature (DAT) sensor is below 72°F (22.2°C), cool air is said to be available. If supply air is above
76°F (24.4°C), warm air is said to be available.
2. Cool Air Available: As space temperature rises above the cooling setpoint, the controller increases
primary airflow. At a space temperature of 2°F (1.1°C) above the cooling setpoint, maximum cooling
airflow is maintained. On a decrease in space temperature, the controller reduces airflow. Below cooling
setpoint, minimum airflow is maintained.
3. The fan is started during occupied and standby modes and runs continuously at maximum fan speed.
The fan induces warm ceiling plenum air as the primary airflow varies and maintains a constant volume to
the space. During unoccupied mode, the fan starts on a call for heating only. The fan stops only during
unoccupied mode when there is no call for heat. EPIC ECM Motor Only: During standby and unoccupied
modes, the fan runs at minimum fan speed.
4. As the space temperature drops below the heating setpoint, the fan continues to recirculate warm
ceiling plenum air.
5. Warm Air Available: As space temperature drops below the heating setpoint, the controller increases
primary airflow. At a space temperature of 2°F (1.1°C) below the heating setpoint, maximum heating
airflow is maintained. On an increase in space temperature, airflow decreases. As space temperature
rises above the heating setpoint, minimum heating airflow is maintained.
