sensor are present. See Economizer Changeover Select section below for further information. ECONOMIZER CHANGEOVER SELECT (E.SEL) — The control is capable of performing any one of the following changeover types in addition to both the dry bulb lockout and the standard external input: E.SEL = 0 none E.SEL = 1 Differential Dry Bulb Changeover E.SEL = 2 Outdoor Enthalpy Changeover E.SEL = 3 Differential Enthalpy Changeover Differential Dry Bulb Changeover — As both return air and outside air temperature sensors are installed as standard on these units, the user may select this option, E.SEL = 1, to perform a qualification of return and outside air in the enabling/ disabling of free cooling. If this option is selected and outsideair temperature is greater than return-air temperature, free cooling will not be allowed. Outdoor Enthalpy Changeover — This option should be used in climates with higher humidity conditions. The P Series control can use an enthalpy switch or enthalpy sensor, or the standard installed outdoor dry bulb sensor and an accessory relative humidity sensor to calculate the enthalpy of the air. Setting ConfigurationECONE.SEL = 2 requires that the user configure ConfigurationECONOA.E.C, the Outdoor Enthalpy Changeover Select, and install an outdoor relative humidity sensor. A control expansion module (CEM) is required. Once the sensor and board are installed, enable ConfigurationECONORH.S, the outdoor relative humidity sensor configuration option. This will automatically enable the CEM board, if it is not enabled already. If the user selects one of the Honeywell curves, A,B,C or D, then OA.E.C options 1-4 should be selected. See Fig. 13 for a diagram of these curves on a psychrometric chart. OA.E.C = 1 Honeywell A Curve Table 54 — Economizer Configuration Table 68 OA.E.C = 2 Honeywell B Curve OA.E.C = 3 Honeywell C Curve OA.E.C = 4 Honeywell D Curve OA.E.C = 5 custom enthalpy curve If the user selects OA.E.C = 5, a direct compare of outdoor enthalpy versus an enthalpy set point is done. This outdoor enthalpy set point limit is configurable, and is called ConfigurationECONOA.EN. Depending on what ConfigurationECONOA.E.C is configured for, if the outdoor enthalpy exceeds the Honeywell curves or the outdoor enthalpy compare value (Configuration ECONOA.EN), then free cooling will not be allowed. NOTE: If the user wishes to disable the standard enthalpy control from running concurrently, a field-supplied jumper must be installed between TB201 terminals 5 and 6. Differential Enthalpy Changeover — This option compares the outdoor-air enthalpy to the return air enthalpy and chooses the option with the lowest enthalpy. This option should be used in climates with high humidity conditions. This option uses both humidity sensors and dry bulb sensors to calculate the enthalpy of the outdoor and return air. An accessory outdoor air humidity sensor (ORH.S) and return air humidity sensor (RRH.S) are used. The outdoor air relative humidity sensor config (ORH.S) and return air humidity sensor config (ConfigurationSENSRRH.S) must be enabled.

NOTE: If the user wishes to disable the standard enthalpy control from running concurrently, a field-supplied jumper must be installed between TB201 terminals 5 and 6. Outdoor Dewpoint Limit Check — If an outdoor relative humidity sensor is installed, the control is able to calculate the outdoor air dewpoint temperature and will compare this temperature against the outside air dewpoint temperature limit configuration (ConfigurationECONO.DEW). If the outdoor air dewpoint temperature is greater than O.DEW, free cooling will not be allowed. Fig. 12 shows a horizontal limit line in the custom curve of the psychrometric chart. This is the outdoor air dewpoint limit boundary. Custom Psychrometric Curves — Refer to the psychrometric chart and the standard Honeywell A-D curves in Fig. 11. The curves start from the bottom and rise vertically, angle to the left and then fold over. This corresponds to the limits imposed by dry bulb changeover, outdoor enthalpy changeover and outdoor dewpoint limiting respectively. Therefore, it is now possible to create any curve desired with the addition of one outdoor relative humidity sensor and the options for changeover now available. See Fig. 12 for an example of a custom curve constructed on a psychrometric chart.
