Fig. 9 shows the new single enthalpy boundariesin the W7220. There are 5 boundaries (setpoints ES1 throughES5), which are defined by dry bulb temperature, enthalpy anddew point.Refer to Table 6 for the ENTH CURVE setpoint values.To use enthalpy the W7220 must have a C7400S Sylkbussensor for OA. The W7220 calculates the enthalpy and dewpoint using the OA temperature and humidity input from the OAsensor. When the OA temperature, OA humidity and OA dewpoint are all below the selected boundary, the economizer setsthe economizing mode to YES, economizing is available.TEMPERATURERATEMPABSOLUTE HUMIDITYES4ES5 ES3 ES2 ES1 HLDUAL ENTHALPYHIGH LIMITECONOMIZINGSINGLE ENTHALPYAVAILABLENOT AVAILABLEP2 (T,RH)P1 (T,RH)ENTHALPYR A H U M ( % RH )Table 6: Single Enthalpy and Dual Enthalpy High Limit Curves.EnthalpyCurveTemp.Dry-Bulb (°F)Temp.Dewpoint (°F)Enthalpy(btu/lb/da)Point P1 Point P2Temp. °F Humidity %RH Temp. °F Humidity %RHES1 80.0 60.0 28.0 80.0 36.8 66.3 80.1ES2 75.0 57.0 26.0 75.0 39.6 63.3 80.0ES3 70.0 54.0 24.0 70.0 42.3 59.7 81.4ES4 65.0 51.0 22.0 65.0 44.8 55.7 84.2ES5 60.0 48.0 20.0 60.0 46.9 51.3 88.5HL 86.0 66.0 32.4 86.0 38.9 72.4 80.3
