Carrier 40UV Installation, Start-Up And Service Instructions Manual page 25

All control offerings provide the following features:
1. A 3-speed automatic fan control that minimizes fan noise by
matching the fan speed to the load. This process provides
better dehumidification during cooling and reduces energy
consumption.
2. American Society of Heating, Refrigeration and Air Conditioning
Engineers (ASHRAE) Cycle I, Cycle II, or Cycle III damper con-
trol options (Cycle II default).
3. Configurable minimum ventilation set point (cfm) for ASHRAE
Cycle II or Cycle III damper control.
4. Demand controlled ventilation with optional sensor to meet ven-
tilation requirements with improved efficiency.
5. Coil freeze protection on all units except non-water units.
