Exhaust Fan The procedure to modify the exhaust fan speed (if equipped) is similar to adjusting the supply fan speed. However, note that the exhaust fan speed operates based on an offset from the supply fan speed. As a result, the parameter to adjust exhaust fan speed is listed as EF VFD OFFSET with an available adjustment range of -20% to +20%. To modify the EF VFD OFFSET parameter follow the instructions below. 1. Using the LCD display on the controller, go to the advanced setpoints menu. 2. Using the PREV and NEXT buttons, move the underscore to the EF VFD OFFSET and press (enter) on the keypad. 3. Use the and (left and right) and and (up/down) arrows to move the cursor to the desired digit allowing the desired output to be entered (e.g., %). 4. Press the enter button to save the change. IMPORTANT Changes to the supply fan speed parameter (SUPPLY FAN SPEED) will affect the speed of the exhaust fan as well. Verification With the changes made to the VFD parameter(s), confirm the VFD/fan speed by enabling the fan to operate. Upon startup, the fan should quickly ramp to the design speed. The speed (in Hz) is indicated on the front of the display. If the controller is sending a fan speed of 100%, fan speed analog output should be 10 VDC and the fan speed should be the design limit.

Occupancy Displays Occupied during the day (occupied hours), Unoccupied and night (unoccupied hours), and Standby (when unit is running in standby. The occupancy of the controller is determined by: Hardwired occupancy input Local time clock/schedule Communicated command from building automation system When a hardwired occupancy input is used, remove the occupancy input jumper wire on Universal Input 15. Connect the occupancy device to that input. The setup parameter for Occupancy Hardwired must be set to True. To use the units standby feature the Occupancy Hardwired must be left at false, occupied and unoccupied will be set via the units stand alone controller. When the stand alone schedule is occupied and the universal input 15 is open the unit will run in standby mode. When the stand alone schedule is occupied and the universal input 15 is closed the unit will run in occupied mode. When the stand alone schedule is unoccupied and the universal input 15 is either open or closed the unit will be in unoccupied mode. The occupancy can also be determined by the local time clock/schedule in the controller. When the local clock/schedule is used, set Occupancy Hardwired to False. Ensure that the time and date are set correctly in the controller. Finally, a communicated command from a building automation system (BAS) can be used to determine the occupancy of the controller. When a communicated command is to be used, set Occupancy Hardwired to False. Communication is possible via several communication protocols including LonTalk, BACnet IP, and BACnet MS/TP. Sup Fan Start Stop True when: Run Stop Input (hardwired) is AllowToRun and System enable is True and All fan alarms are False and Duct static pressure high limit is False (duct static VAV units) and Occupancy is True (occupied) or Night operation is True (night heating, cooling, or dehumidification) Range: True, False Supply Fan Speed Displays the defined speed for the supply fan. The rooftop unit includes a variable frequency drive (VFD) for the supply fan motor. In constant volume operation, the speed of the fan remains constant at the defined speed (50-100%, adjustable).
