3. “Safeties by Others”: This note implies that the associated equipment has safety

features installed, for example adding mechanical stops to the dampers.

Application 2860 VAV Cooling Only

In Application 2860, the controller modulates the supply air damper of the terminal box

for cooling. In order for it to work properly, the central air-handling unit must provide

cool supply air.
See the following figure.

Application 2861 VAV Cooling or Heating

In Application 2861, the controller modulates the supply air damper of the terminal box

for cooling and heating. In order for it to work properly, the central air-handling unit

must provide cool supply air in cooling mode and warm air during heating mode.
See the following figure.

Application 2862 VAV with Electric Reheat or Baseboard Radiation

In Application 2862, the controller modulates the supply air damper of the terminal box

for cooling and controls stages of electric reheat or baseboard radiation for heating.

When in heating, the terminal box either maintains minimum airflow or modulates the

supply air damper. In order for the terminal box to work properly, the central air-

handling unit must provide supply air.
See the following figure.
