DpCngOvrLt: Wheel Dewpoint Changeover Limit. This is the point at which the Discharge air temp swaps
between the DatSpHiDp setpoint and the DatSpLoDp setpoint.
52 - 65°F
(11-18°C)
59ºF (15°C)
DatSpHiDp: Discharge Air Temperature Setpoint with High Dewpoint . This setpoint is used when the ER
Wheel Dewpoint is greater than the DpCngOvrLt setpoint.
52 - 75°F
(11 - 24°C)
58ºF (14°C)
*DatClgSpLoDp:
Discharge Air Temperature Cooling Setpoint with Low Dewpoint. This setpoint is used when the

than the HtgClgCngOvr setpoint.
52 - 75°F
(11 - 24°C) 60ºF (15.5°C)
*DatHtgSpLoDp:
Discharge Air Temperature Heating Setpoint with Low Dewpoint. This setpoint is used when the
ER Wheel Dewpoint is lower than the DpCngOvrLt setpoint and the OA temperature is less than
the HtgClgCngOvr setpoint.
