FACTORY OPTIONS AND/OR ACCESSORIESEconomizer (dry--bulb or enthalpy)Non--Fused DisconnectEconomizers 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.This OSHA-- compliant, factory-- installed, safety switchallows a service technician to locally secure power to therooftop.CO2 SensorRTU Open Protocol ControllerImproves 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.Connect 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.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 asrequired by code. The “unpowered” option is to bepowered from a separate 115/120v power source.Power Exhaust with Barometric ReliefSuperior internal building pressure control. Thisfield-- installed accessory or factory-- installed option mayeliminate the need for costly, external pressure controlfans.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 befactory-- installed, or easily field-- installed. Not availablewith 2-- speed indoor fan motor.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 PremierLinkr, 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 inconjunction with a compatible unit controller/thermostat,the switches will activate an alarm to warn the appropriatepersonnel.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%versions.6
FACTORY OPTIONS AND/OR ACCESSORIES (cont.)Optional Humidi--MiZer AdaptiveDehumidification SystemCarrier’s Humidi-- MiZer adaptive dehumidificationsystem is an all-- inclusive factory installed option that canbe ordered with any WeatherMaker 50TC18-- 29 rooftopunit.This system expands the envelope of operation ofCarrier’s WeatherMaker rooftop products to provideunprecedented flexibility to meet year round comfortconditions.The Humidi-- MiZer adaptive dehumidification system hasthe industry’s only dual dehumidification mode setting.The Humidi-- MiZer system includes two new modes ofoperation.The WeatherMaker 50TC18-- 29 rooftop coupled with theHumidi-- MiZer system is capable of operating in normaldesign cooling mode, subcooling mode, and hot gas reheatmode. Normal design cooling mode is when the unit willoperate under its normal sequence of operation by cyclingcompressors to maintain comfort conditions.Subcooling mode will operate to satisfy part load typeconditions when the space requires combined sensible anda higher proportion of latent load control. Hot Gas Reheatmode will operate when outdoor temperatures diminishand the need for latent capacity is required for solehumidity control. Hot Gas Reheat mode will provideneutral air for maximum dehumidification operation.Staged Air Volume (SAV) Indoor Fan SpeedSystemCarrier’s Staged Air Volume (SAV) system saves energyand installation time by utilizing a Variable FrequencyDrive (VFD) to automatically adjust the indoor fan motorspeed in sequence with the units cooling operation. PerASHRAE 90.1 2010 standard section 6.4.3.10.b, duringthe first stage of cooling operation the VFD will adjust thefan motor to provide 2/3rd of the total cfm established forthe unit. When a call for the second stage of cooling isrequired, the VFD will allow the total cfm for the unitestablished (100%). During the heating mode the VFDwill allow total design cfm (100%) operation and duringthe ventilation mode the VFD will allow operation to2/3rd of total cfm.Compared to single speed indoor fan motor systems,Carrier’s SAV system can save substantial energy, 25% *,versus single speed indoor fan motor systems.The VFD used in Carrier’s SAV system has soft startcapabilities to slowly ramp up the speeds, thus eliminatingany high inrush air volume during initial start-- up. It alsohas internal over current protection for the fan motor anda field installed display kit that allows adjustment and indepth diagnostics of the VFD.This SAV system is available on models with 2-- stagecooling operation with electrical mechanical or RTUOpen, Multi Protocol controls. Both space sensor andconventional thermostats controls can be used to provideaccurate control in any application.The SAV system is very flexible for initial fanperformance set up and adjustment. The standard factoryshipped VFD is pre-- programmed to automatically stagethe fan speed between the first and second stage ofcooling. The unit fan performance static pressure and cfmcan be easily adjusted using the traditional means ofpulley adjustments. The other means to adjust the unitstatic and cfm performance is to utilize the field installedDisplay Kit and adjust the frequency and voltage in theVFD to required performance requirements. In either case,once set up, the VFD will automatically adjust the speedbetween the cooling stage operations.*Data based on .10 ( /kWh) in an office applicationutilizing Carrier’s HAP 4.6 simulation software programMotormaster 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 lowambient cooling operation. This device should be used asan alternative to economizer free cooling not wheneconomizer usage is either not appropriate or desired. TheMotormaster will either cycle the outdoor-- fan motors oroperate them at reduced speed to maintain the unitoperation, depending on the model.MotorMaster allows cooling operation down to - 20 F(-- 29 C) ambient conditions.Winter Start KitThe winter start kit by Carrier extends the low ambientlimit of your rooftop to 25 F (-- 4 C). The kit bypasses thelow pressure switch, preventing nuisance tripping of thelow pressure switch. Other low ambient precautions maystill be prudent.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 installedcombination to meet your application. A wide selection ofmotors and pulleys (drives) are available, factoryinstalled, to handle nearly any application.Thru--the--Base ConnectionsThru-- the-- base provisions/connection points are availableas standard with every unit. When bottom connections arerequired, field furnished couplings are required.7
FACTORY OPTIONS AND/OR ACCESSORIES (cont.)Hinged Access PanelsAllows access to unit’s major components withspecifically designed hinged access panels. Panels are:filter, control box and fan motor.Electric Heaters / Single Point KitCarrier offers a full-- line of field-- installed accessoryheaters and single point kits when required. The heatersare very easy to use, install and are all pre-- engineered andcertified.Carrier Energy Demand System(EDS)The Energy Demand System is as easy to install asthermostats, and requires no special training. Everycontroller has a built-- in self-- configuring wirelessnetwork. The controllers work together to establish awireless network, eliminating the need for expensivewiring. The secure web portal allows property managersto easily access multiple sites from any internetconnection to monitor building performance andreconfigure controllers for demand response or thescheduling of loads.S Simple, affordable, wireless electrical demandmanagementCarrier’s wireless automated demand management anddemand response controllers can be easily installed ontoany packaged rooftop unit.
