OPTIONS / ACCESSORIESECONOMIZER OPTIONSFactory assembled and wired economizer dampers andcontrols are available for field installation.Heavy-gauge galvanized steel cabinet is completelyinsulated with thick, matte-faced fiberglass insulation.Large removable panels on both sides of cabinetprovide complete service access.Mounting flanges provide ease of connection to airhandler unit.Flanges on outdoor air opening and return air openingpermit easy duct connection.Damper linkage and shafts are plated.Factory or Field InstalledStandard Economizer Features(Not for Title 24)Gear-driven action, return air and outdoor air dampers,plug-in connections to unit, neoprene seals, 24-volt, fully-modulating spring return motor, adjustableminimum damper position.Standard EconomizerControl ModuleThe Standard Economizer ControlModule can be adjusted to operatebased on outdoor air temperatures.Economizer Controls:• Damper Minimum Position - Canbe set lower than traditionalminimum air requirementsresulting in cost savings.• IAQ Sensor - Signals dampers to modulate andmaintain 55°F when CO 2is higher than the CO 2setpoint.• Demand Control Ventilation (DCV) LED - A steadygreen Demand Control Ventilation LED indicatesthe IAQ reading is higher than setpoint andrequires more fresh air.• Free Cool LED - A steady green LED indicatesoutdoor air is suitable for free cooling.Free Cooling runs when outdoor air temperature is lowerthan the set temperature on the economizer control.NOTE: The Free Cooling default setting for outdoor airtemperature sensor is 55°F.High PerformanceEconomizer FeaturesApproved for California Title 24 building standards.ASHRAE 90.1-2010 compliant.Gear-driven action, high torque 24-volt fully-modulatingspring return damper motor, return air and outdoor airdampers, plug-in connections to unit, nylon bearings,enhanced neoprene blade edge seals and flexiblestainless steel jamb seals to minimize air leakage.NOTE - High Performance Economizers are notapproved for use with enthalpy controls in Title 24applications.High PerformanceEconomizer Control ModuleModule provides inputs and outputs to controleconomizer based on parametersettings.Module automatically detectssensors by polling to determinewhich sensors are installed insystem.Module displays any alarm messages (fault detectionand diagnostics) as an aid in troubleshooting.Non-volatile memory retains parameter settings in caseof power failure.Keypad with four navigation buttons and LCD screen isfurnished for setting economizer parameters.• Menu Up/Exitbutton returns to the main menu.• Arrow Up button moves to the previous or nextparameter within the selected menu.• Arrow Down button moves to the next parameterwithin the selected menu.• Select (enter)selection.Main Menu Structure:button confirms parameter• STATUS (economizer and system operation status)• SETPOINTS (settings for various setpointparameters)• SYSTEM SETUP (settings/information about thesystem)• ADVANCED SETUP (freeze protection, CO 2settings, stage 3 delay and additional calibrationsettings)• CHECKOUT (damper positions)• ALARMS (output signal that can be configured forremote alarm monitoring)NOTE - The free cooling setpoint for Title 24applications must be set based on the Climate Zonewhere the system is installed. See Section 140.4“Prescriptive Requirements for Space ConditioningSystems” of the California Energy Commission’s 2013Building Energy Efficiency Standards.Refer to Installation Instructions for complete setupinformation and menu parameters available.Field InstalledDifferential Enthalpy Control(Not for Title 24)Allows the outdoor air enthalpy control to selectbetween outdoor air or return air, whichever has lowerenthalpy.
