6FACTORY OPTIONS AND/OR ACCESSORIESEconomizerEconomizers save energy, money and improve comfortlevels in the conditioned space. They bring in fresh,outside air for ventilation; and provide cool outside air tocool your building. This also is the preferred method oflow ambient cooling. When integrated with CO2 sensors,economizers can provide even more savings by couplingthe ventilation air to only that amount required based onspace occupancy. Economizers are available, installed andtested by the factory, with either enthalpy or temperaturedry--bulb inputs. There are also models forelectromechanical, direct digital controllers and singlespeed fan or 2--speed indoor fan motors. Additionalsensors are available as accessories to optimize theeconomizer. Economizers include gravity controlledbarometric relief that helps equalize building pressure andambient air pressures. This can be a cost effective solutionto prevent building pressurization. Economizers areavailable in Ultra Low Leak and standard low leakversions.CO 2 SensorImproves productivity and saves money by working withthe economizer to intake only the correct amount ofoutside air for ventilation. As occupants fill your building,the CO2 sensor detects their presence through increasingCO2 levels, and opens the economizer appropriately.When the occupants leave, the CO2 levels decrease, andthe sensor appropriately closes the economizer. Thisintelligent control of the ventilation air, called DemandControl 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 detectorsimmediately shut down the rooftop unit when smoke isdetected. They are available, installed by the factory, forsupply air, return air, or both.Louvered Hail GuardsSleek, louvered panels protect the condenser coil fromhail damage, foreign objects, and incidental contact.Convenience Outlet (powered or un--powered)Reduce service and/or installation costs by including aconvenience outlet in your specification. Carrier willinstall this service feature at our factory. Provides aconvenient, 15 amp, 115v GFCI receptacle with “Wet inUse” cover. The “powered” option allows the installer topower the outlet from the line side of the disconnect orload side as required by code. The “un--powered” option isto be powered from a separate 115/120v power source.Non--fused DisconnectThis OSHA--compliant, factory installed, safety switchallows a service technician to locally secure power to therooftop.Disconnect Switch BracketProvides a pre--engineered and sized mounting bracket forapplications requiring a unit mounted fused and non--fuseddisconnect of greater than 100 amps. Bracket assures thatno damage will occur to coils when mounting with screwsand other fasteners (16 size only).Power Exhaust with Barometric ReliefSuperior internal building pressure control. This fieldinstalled accessory may eliminate the need for costly,external pressure control fans.PremierLink, DDC ControllerThis CCN controller regulates your rooftop’s performanceto tighter tolerances and expanded limits, as well asfacilitates zoning systems and digital accessories. It alsounites your Carrier HVAC equipment together on one,coherent CCN network. The PremierLink can be factoryinstalled, or easily field installed. Not available with2--speed Staged Air Volume (SAV) system.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 (Bacnet,Modbus, N2, and Lonworks). Use this controller whenyou have an existing BAS.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 afterstopping. Not required with PremierLink, RTU Open, orauthorized commercial thermostats.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 allowventilation air and closes when the rooftop stops, stoppingunwanted infiltration.Manual OA DamperManual outdoor air dampers are an economical way tobring in ventilation air. The dampers are available in 25%and 50% versions.Optional Humidi--MiZer AdaptiveDehumidification SystemCarrier’s Humidi--MiZer Adaptive DehumidificationSystem is an all--inclusive factory installed option that canbe ordered with any WeatherMaker 48TC**04--16 rooftopunit.
