High Temp Cap Override (H.TMP) — If stages of mechanical cooling are on and the error is greater than twice Y.PLU, and the rate of change of error is greater than 0.5F, then a stage of mechanical cooling will be added every 30 seconds. This override is intended to react to situations where the load rapidly increases. Low Temp Cap Override (L.TMP) — If the error is less than twice Y.MIN, and the rate of change of error is less than –0.5F, then a mechanical stage will be removed every 30 seconds. This override is intended to quickly react to situations where the load is rapidly reduced. Pull Down Cap Override (PULL) — If the error from set point is above 4F, and the rate of change is less than –1F per minute, then pulldown is in effect, and “SUM” is set to 0. This keeps mechanical cooling stages from being added when the error is very large, but there is no load in the space. Pulldown for units is expected to rarely occur, but is included for the rare situation when it is needed. Most likely pulldown will occur when mechanical cooling first becomes available shortly after the control goes into an occupied mode (after a warm unoccupied mode). Slow Change Cap Override (SLOW) — With a rooftop unit, the design rise at 100% total unit capacity is generally around 30 F. For a unit with 4 stages, each stage represents about 7.5F of change to EDT. If stages could reliably be cycled at Table 83 — Economizer Run Status Display Table 104 very fast rates, the set point could be maintained very precisely. Since it is not desirable to cycle compressors more than 6 cycles per hour, slow change override takes care of keeping the PID under control when “relatively” close to set point. VFD INFORMATION DISPLAY TABLE — The VFD information display table provides information on the supply fan VFD and exhaust fan VFD. See Table 85. MODE TRIP HELPER — The Mode Trip Helper table provides information on the unit modes and when the modes start and stop. See Table 86. This information can be used to help determine why the unit is in the current mode. CCN/LINKAGE DISPLAY TABLE — The CCN/Linkage display table provides information on unit linkage. See Table 87. COMPRESSOR RUN HOURS DISPLAY TABLE — The Compressor Run Hours Display Table displays the number of run time hours for each compressor. See Table 88. COMPRESSOR STARTS DISPLAY TABLE — The Compressor Starts Display Table displays the number of starts for each compressor. See Table 89. SOFTWARE VERSION NUMBERS DISPLAY TABLE — The Software Version Numbers Display Table displays the software version numbers of the unit boards and devices. See Table 90.
