25Table 7 — Standard Control OfferingsAll control offerings provide the following features:1. A 3-speed automatic fan control that minimizes fan noise bymatching the fan speed to the load. This process providesbetter dehumidification during cooling and reduces energyconsumption.2. American Society of Heating, Refrigeration and Air ConditioningEngineers (ASHRAE) Cycle I, Cycle II, or Cycle III damper con-trol options (Cycle II default).3. Configurable minimum ventilation set point (cfm) for ASHRAECycle 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, coolingand damper controls to maintain temperature.7. Adjustable filter maintenance timer on all units.8. Direct shaft coupled, electric actuators on all dampers. Springreturn on outdoor-air (OA) damper.9. Spring return modulating water valves.10. Optional relative humidity sensor for high humidity control ordehumidification.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.LEGENDTable 8 — Field-Installed AccessoriesTable 9 — Factory-Installed OptionsCONTROL SEQUENCE APPLICATIONHeating/Cooling Valve Control2A/3A Chilled Water/Hot Water, 2-Pipe Changeover2B/3B Chilled Water/Hot Water or Steam, 4-Pipe2D/3D Chilled Water with Electric Heat2F/3F Hot Water or Steam Heating Only2G/3G Hot Water or Steam with DX Cooling2J/3J Chilled Water Cooling OnlyHeating/Cooling with Face and Bypass Damper Control20/30 Chilled Water/Hot Water, 2-Pipe Changeover21/31 Chilled Water/Hot Water or Steam, 4-Pipe22/32 Chilled Water with Electric Heat23/33 Hot Water or Steam with DX Cooling24/34 Hot Water or Steam Heating Only25/35 Chilled Water Cooling OnlyHeating/Cooling with Humidity Control2M/3M F&B Chilled Water/Hot Water or Steam Heating 4-Pipe plus Valve Control Reheat forDehumidification2G/3G Cooling with Hot Water or Steam Reheat, Valve Control2B/3B Chilled Water/Hot Water Reheat, 4-Pipe Valve Control2K/3K F&B Chilled Water Cooling with Hot Water or Steam Valve Control Reheat, 4-PipeNon-Water SystemsOC Electric Heat OnlyOE Electric Heat with DX CoolingOH DX Cooling OnlyDX — Direct ExpansionF&B — Face and BypassPACKAGE NO.
