Fan Coil Unit (typical of 2) Run Conditions - Scheduled: The unit will run according to a user definable time schedule in the following modes: • Occupied Mode: The unit will maintain • A 75°F (adj.) cooling setpoint • A 70°F (adj.) heating setpoint. • Unoccupied Mode (night setback): The unit will maintain • A 85°F (adj.) cooling setpoint. • A 55°F (adj.) heating setpoint. Alarms will be provided as follows: • High Zone Temp: If the zone temperature is greater than the cooling setpoint by a user definable amount (adj.). • Low Zone Temp: If the zone temperature is less than the heating setpoint by a user definable amount (adj.). Demand Limiting - Zone Setpoint Optimization: To lower power consumption, the zone setpoints will automatically relax when the facility power consumption exceeds definable thresholds. The amount of relaxation will be individually configurable for each zone. The zone setpoints will automatically return to their previous settings when the facility power consumption drops below the thresholds. Zone Setpoint Adjust: The occupant will be able to adjust the zone temperature heating and cooling setpoints at the zone sensor. Zone Optimal Start: The unit will use an optimal start algorithm for morning start-up. This algorithm will minimize the unoccupied warm-up or cool-down period while still achieving comfort conditions by the start of scheduled occupied period. Zone Unoccupied Override: A timed local override control will allow an occupant to override the schedule and place the unit into an occupied mode for an adjustable period of time. At the expiration of this time, control of the unit will automatically return to the schedule. Smoke Detection: The unit will shut down and generate an alarm upon receiving a smoke detector status. Fan: The fan will run anytime the unit is commanded to run, unless shutdown on safeties. Cooling Coil Valve: The controller will measure the zone temperature and modulate the cooling coil valve to maintain its cooling setpoint. The cooling will be enabled whenever: • Outside air temperature is greater than 60°F (adj.). • AND the zone temperature is above cooling setpoint. • AND the fan is on. The cooling coil valve will open whenever the freezestat (if present) is on. Heating Coil Valve: The controller will measure the zone temperature and modulate the heating coil valve to maintain its heating setpoint. The heating will be enabled whenever: • Outside air temperature is less than 65°F (adj.). • AND the zone temperature is below heating setpoint. • AND the fan is on. The heating coil valve will open whenever the freezestat (if present) is on. Economizer: The controller will measure the zone temperature and modulate the mixed air dampers in sequence to maintain the zone cooling setpoint. The outside air dampers will maintain a minimum adjustable position of 20% (adj.) open whenever occupied. The economizer will be enabled whenever: • Outside air temperature is at least 3°F (adj.) less than the Zone Temperature. • AND the outside air temperature is less than 75°F (adj.) The economizer will close whenever the freezestat (if present) is on. The outside air dampers will close and the return air damper will open when the unit is off. If Optimal Start Up is available the mixed air damper will operate as described in the occupied mode except that the outside air damper will modulate to fully closed. Minimum Outside Air Ventilation - Fixed Percentage: The outside air dampers will maintain a minimum position (adj.) during building occupied hours and be closed during unoccupied hours. Sample Project Somewhere, Maryland Discharge Air Temperature: The controller will monitor the discharge air temperature.

Fan Status: The controller will monitor the fan status. Alarms will be provided as follows: • Fan Failure: Commanded on, but the status is off. • Fan in Hand: Commanded off, but the status is on. • Fan Runtime Exceeded: Fan status runtime exceeds a user definable limit (adj.). Zone Carbon Dioxide (CO2) Concentration Monitoring: The controller will measure the zone CO2 concentration. Alarms will be provided as follows: • High Zone Carbon Dioxide Concentration: If the zone CO2 concentration is greater than 1000ppm (adj.) when in the occupied mode. Zone Humidity: The controller will monitor the zone humidity. Alarms will be provided as follows: • High Zone Humidity: If the zone humidity is greater than 70% (adj.). • Low Zone Humidity: If the zone humidity is less than 35% (adj.).
