CONTROL SEQUENCE N302
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. Any time warm air is available, auxiliary heat is locked out.
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. Supplemental Heat: As the space temperature drops below the heating setpoint, the heating output
modulates open. As the space temperature rises towards the heating setpoint, the heating modulates closed.
If the heating loop is less than 10%, the heating output remains at 0%.
5. If DAT limiting is enabled and a DAT sensor is detected, the discharge air heating setpoint is determined
based on the heating loop. The discharge temperature is limited to 15°F (8.3°C) above space temperature up
to a maximum of 90°F (32.2°C).
6. 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.
