When fan tracking learning is enabled,the control will add an offset to the Fan Track Initial DCFM(Configuration→BP→FAN.T→FT.ST) if the building pres-sure deviates from the Building Pressure Set Point (BP.SP).Periodically, at the rate set by the Fan Track Learn Rate(FT.TM) the delta cfm is adjusted upward or downward with amaximum adjustment at a given instance to be no greater thanFan Track Max correction (FT.AD). The delta cfm can notever be adjusted greater than or less than the Fan Track MaxClamp (FT.MX).Set Clock on VFD (If Installed) — The clock setmode is used for setting the date and time for the internal clockof the VFD. In order to use the timer functions of the VFDcontrol, the internal clock must be set. The date is used to deter-mine weekdays and is visible in the fault logs. Refer to theVFD section in Appendix D on page 160 for information onoperating the VFD and using the keypad.To set the clock, perform the following procedure from theVFD keypad:1.
