Duct Static Press Displays the interpreted value of the voltage read from the duct static pressure sensor. The duct static pressure sensor should be field installed approximately 2/3 down the supply duct. The output signal from the sensor must be 0-10 VDC. The duct static pressure sensor, when used, must be connected to Universal Input 12 on the 34 point module or Universal Input 1 on the 16 point module on the controller depending on the configuration of the ventilator. For the sensor voltage to be interpreted correctly, the conversion scale and offset values must be set up correctly for that device (refer to the Appendix). View Only Space Enthalpy Calculated based on the field installed (factory provided if ordered) space temperature sensor and field installed (factory provided if ordered) space humidity sensor. View Only Outside Air Enthalpy Calculated based on factory installed RH sensor and factory installed outside air temperature sensor. View Only AFMS Sensor Measured by the either the Inlet cone sensor or AMD damper located in the outside air inlet. This is the actual air flow being measured in CFM as calculated by the factory calibrated air flow measuring station. View Only HP Ckt A Press Measured with a pressure transducer factory installed in the refrigeration piping. The signal from the sensor will be a 0-10 VDC signal with a range of 0-750 psi. The sensor is wired to Universal Input 3 on the expansion module of the controller. View Only HP Ckt B Press Measured with a pressure transducer factory installed in the refrigeration piping. The signal from the sensor will be a 0-10 VDC signal with a range of 0-750 psi. The sensor is wired to Universal Input 8 on the expansion module of the controller. View Only HP Ckt A Temp Displays the calculated value for circuit A's condensing temperature when in cooling mode, and suction temperature when in heating mode. View Only HP Ckt B Temp Displays the calculated value for circuit B's condensing temperature when in cooling mode, and suction temperature when in heating mode.

Dampers Outside Air Damper Position Displays the status of the modulating damper percentage. Analog Output 1 is used to control modulating dampers. For units with no return dampers, the outside dampers are first controlled Open. When damper operation is confirmed (damper end switch True), the supply fan is enabled. For units with return dampers, the supply fan is enabled prior to damper operation. View Only Damper End Switch Displays the status of the damper end switch universal input 7. When the damper end switch is True, at least one of the dampers (outside or return) is sufficiently open for air flow. On units with only outside air dampers (no return dampers), the supply fan can only operate when the damper end switch is made (True). View Only OAD Min Position Minimum position of the damper during occupied operation. The outside damper is always closed during unoccupied operation for units with return air dampers. Editable Range: 0-100% Default: 100% Allow Econo This point allows user to select if the unit utilizes the economizer function: 5. Enab Econ 6. Disab Econ (default) Editable Econo W/Cool Ena Allows user to select whether the unit allows economizer operation along with mechanical cooling or only as a first stage of cooling. 7. Enab Econ With Cooling (default) 8. Disab Econ With Cooling Editable Temp or Enth Sel Select whether the unit bases its economize calculations on space enthalpy vs. outside air enthalpy or space temperature vs. outside air enthalpy. For units with no space temperature connected, OAT based economizer will automatically be selected. 9. Enthalpy Econo (default) 10. Temperature Econo Editable Econo Type Temp or OA Based Select whether the unit bases its economize calculations on space temp vs. setpoint or OAT vs. setpoint. For units with no space temperature connected, OAT based economizer will automatically be selected. 11. OAT Only 12. Space Temp (default) Editable Controls V2 IOM 23 May 2011 Part Number 474626
