SEQUENCE OF OPERATION:

1. Changeover: If the discharge air temperature (DAT)
drops below 72°F, cool air is said to be available. As the
DAT rises above 76°F, warm air is said to be available.

2. Cool air available: As space temperature rises above
the cooling setpoint, the controller increases airfl ow. At
a space temperature of 2°F above the cooling setpoint,
maximum cooling airfl ow is maintained. On a decrease
in space temperature, the controller reduces airfl ow.
Below cooling setpoint, minimum cooling airfl ow is
maintained.

3. Warm air available: As space temp drops below the
heating setpoint, the controller increases airfl ow. At a
temperature 2°F below the heating setpoint, maximum
heating airfl ow is maintained. On an increase in space
temperature, airfl ow decreases. As space temperature
rises above the heating setpoint, minimum heating
airfl ow is maintained.
