Table 7 — Standard Control Offerings
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.
6. Proportional Integrated Derivative (PID) logic heating, cooling
and damper controls to maintain temperature.
7. Adjustable filter maintenance timer on all units.
8. Direct shaft coupled, electric actuators on all dampers. Spring
return on outdoor-air (OA) damper.
9. Spring return modulating water valves.
10. Optional relative humidity sensor for high humidity control or
dehumidification.
11. Optional remote-mounted space sensor with set point adjust-
ment, tenant override, and service port jack.
12. Optional linkage thermostat with time clock, set point adjust-
ment, schedule and holiday programming, digital temperature,
set point and equipment status display.
