Factory-installed optionsEconomizer (dry bulb or enthalpy)Economizers save money. They bring in fresh, outside airfor ventilation; and provide cool, outside air to cool yourbuilding. This is the preferred method of low ambient cooling. When coupled to CO2 sensors, Economizers can provide even more savings by coupling the ventilation air toonly that amount required.Economizers are available, installed and tested by the factory, with either enthalpy or dry bulb temperature inputs.There are also models for electromechanical as well asdirect digital controllers. Additional sensors are available asaccessories to optimize the economizers.Economizers include gravity-controlled barometric reliefwhich equalizes building pressure and ambient air pressures. This can be a cost effective solution to prevent building pressurization.CO2 SensorImproves productivity and saves money by working withthe economizer to intake only the correct amount of outside air for ventilation. As occupants fill your building, theCO2 sensor detects their presence through increasing CO2levels, and opens the economizer appropriately.When the occupants leave, the CO2 levels decrease, andthe sensor appropriately closes the economizer. This intelligent control of the ventilation air, called Demand Controlled Ventilation (DCV), reduces the overall load on therooftop, saving money.Smoke DetectorsTrust the experts. Smoke detectors make your applicationsafer and your job easier. Carrier smoke detectors immediately shut down the rooftop unit when smoke is detected.They are available, installed by the factory, for supply air,return air, or both.Louvered Hail GuardsSleek, louvered panels protect the condenser coil from haildamage, foreign objects, and incidental contact.Convenience Outlet (powered or un-powered)Lower service bills by including a convenience outlet inyour specification. Carrier will install this service feature atour factory, powered. Provides a convenient 15 amp,115V GFCI receptacle.Non-fused DisconnectThis OSHA-compliant, factory-installed, safety switchallows a service technician to locally secure power to therooftop.Motorized 2-Position DamperThe new Carrier 2-position, motorized outdoor air damperadmits up to 100% outside air. Using reliable, gear-driventechnology, the 2-position damper opens to allow ventilation air and closes when the rooftop stops, stoppingunwanted infiltration.PremierLink This CCN controller regulates your rooftop’s performanceto tighter tolerances and expanded limits, as well as facilitates zoning systems and digital accessories. It also unitesyour Carrier HVAC equipment together on one, coherentCCN network. The PremierLink can be factory-installed,or easily field-installed.RTU Open, Multi-protocol ControllerConnect the rooftop to an existing BAS without needingcomplicated translators or adapter modules using the RTUOpen controller. This new controller speaks the 4 mostcommon building automation system languages (BACnet1,Modbus2, N2, and Lonworks3). Use this controller whenyou have an existing BAS.Alternate Motors and DrivesSome applications need larger horsepower motors, someneed more airflow, and some need both. Regardless of thecase, your Carrier expert has a factory installed combination to meet your application. A wide selection of motorsand pulleys (drives) are available, factory installed, to handle nearly any application.Thru-the-Base ConnectionsThru-the-base connections, available as either an accessoryor as a factory option, are necessary to ensure proper connection and seal when routing wire and piping through therooftop’s basepan and curb. These couplings eliminateroof penetration and should be considered for gas lines,main power lines, as well as control power.Field-installed accessoriesPower Exhaust Pressure ReliefSuperior internal building pressure control. This fieldinstalled accessory may eliminate the need for costly, external pressure control fans.Time Guard II Control CircuitThis accessory protects your compressor by preventingshort-cycling in the event of some other failure, preventsthe compressor from restarting for 30 seconds after stopping. Not required with PremierLink, RTU Open, orauthorized commercial thermostats.Filter or Fan Status SwitchesUse these differential pressure switches to detect a filterclog or indoor fan motor failure. When used in conjunctionwith a compatible unit controller/thermostat, the switcheswill activate an alarm to warn the appropriate personnel.Manual OA DamperManual outdoor air dampers are an economical way tobring in ventilation air. The dampers are available in 25%and 50% versions.Motormaster Head Pressure ControllerThe Motormaster motor controller is a low ambient, headpressure controller kit that is designed to maintain theunit’s condenser head pressure during periods of low ambient cooling operation. This device should be used as analternative to economizer free cooling not when economizer usage is either not appropriate or desired. TheMotormaster will either cycle the outdoor fan motors oroperate them at reduced speed to maintain the unit operation, depending on the model.Electric HeatersCarrier offers a full line of field-installed accessory heaters.The heaters are very easy to use and install. All are preengineered and certified.1. BACnet is a registered trademark of ASHRAE (American Society ofHeating, Refrigerating, and Air-Conditioning Engineers).2.
