Controls—DDCTrane DDC–UCMControl Logic—DDC controllers are today’s industrystandard. DDC controllers providesystem-level data used to optimizesystem performance. Variables such asoccupied/unoccupied status, minimumand maximum airflow setpoints,temperature and temperaturesetpoints, valve position, fan status (onor off, and mode of operation: series orparallel), reheat status (on or off), boxtype and air valve size, temperaturecorrection offsets, flow correctionvalues, ventilation fraction, etc. areavailable on a simple twisted-shieldedwire pair.Trane DDC controllers provide Tranedesigned, solid-state electronicsintended specifically for VAVtemperature control in space comfortapplications. DDC control capabilitiesinclude: Proportional plus integral control loopalgorithm for determining requiredairflow needed to control roomtemperature. Airflow is limited byactive minimum and maximumairflow setpoints. Pressure-independent (PI) operation,which automatically adjusts valveposition to maintain required airflow.In certain low-flow situations or incases where the flow measurementhas failed, the DDC controller willGeneralLogicoperate in a pressure-dependent (PD)mode of operation. Cooling and heating control action ofair valve. In cooling control action, theDDC controller matches cooling airflowto cooling load. In heating controlaction, the DDC controller matches theheating airflow to control heating load.The DDC controller will automaticallychange over to cooling control action ifthe supply air temperature is below theroom temperature and willautomatically change over to heatingcontrol action if the supply airtemperature is 10 F or more above theroom temperature. If the supply airtemperature is between the roomtemperature and the roomtemperature plus 10 F, then the DDCcontroller will provide the activeminimum airflow.The DDC controllerfirst chooses theTracer Summitsupplied supply air temperature valueto use for auto changeover. If this is notavailable, it uses the temperatureprovided by the optional auxiliarytemperature sensor. If this is also notavailable, it uses the heating/coolingmode assigned byTracer Summit orthe DDC controller’s service tool(Everyware TM or RoverTM V4). Multiple reheat control optionsincluding staged electric, staged hotwater (normally on or normally off),proportional hot-water, and slowpulsed width modulation. Modulatingreheat options utilize a separate reheatproportional-plus-integral control loopfrom that controlling airflow into theroom. Staged reheat options utilize acontrol algorithm based on heatingsetpoint and room temperature. 24 VAC binary input that can beconfigured as a generic input or asoccupancy input. When the DDCcontroller is operation withTracerSummit, the status of the input isprovided toTracer Summit for itsaction. In stand-alone operation andwhen configured for an occupancyinput, the input will control occupancystatus of the DDC controller. Auxiliary temperature analog inputthat can be configured for an auxiliarytemperature sensor or a 2-to-10 VDCCO2 sensor. When configured fortemperature, the value of the input isused as status-only by Tracer Summit ifTracer Summit is providing a supply airtemperature to the DDC controller.Otherwise, the input will be used fordetermining control action of the DDCcontroller. When configured for a CO2sensor, the value of the input is used asa status-only input by Tracer Summit. Dual-duct support with two DDCcontrollers. One DDC controllercontrols the cooling air valve and theother controller controls the heating airvalve. With constant-volumesequences, the discharge air volume isheld constant by controlling dischargeair volume with the heating UCM.Flow Sensor Signal vs. Airflow Delivery5Flow Sensor DP (In. wg)14"5"6"8"10"12" 14" 16"0.10.01101001,00010,000CfmC4Note: Flow sensor DP (in. wg) is measured at the flow ring to aid in system balancing and commissioning.

Controls—DDCDDC Remote HeatControl OptionsWhen heat is added to the primary airat the VAV unit before it enters thezone, the air is said to be reheated. Theoperating characteristics of the fourbasic types of VariTrane DDC terminalreheat are discussed.Single-Duct: On/Off Hot WaterReheat—Three stages of on/off hotwater reheat are available. The watervalves used are 2-position and areeither fully-opened or fully-closed. Theheating minimum airflow setpoint isenabled during reheat.Stage 1 energizes when the spacetemperature is at or below the heatingsetpoint. When the zone temperaturerises above the active heating setpointby 0.5 F (0.28 C), stage 1 is deenergized. Stage 2 energizes when thespace temperature is 1 F (0.56 C) ormore below the active heatingsetpoint, and is de-energized when thespace temperature is 0.5 F (0.28 C)below the active heating setpoint.Stage 3 energizes when the zonetemperature is 2 F (1.11 C) or morebelow the active heating setpoint, andde-energizes when the spacetemperature is 1.5 F (0.83 C) below theactive heating setpoint. When reheat isde-energized, the cooling minimumairflow setpoint is activated.VCEFSingle-Duct: Proportional HotWater Reheat—Proportional hotwater reheat uses 3-wire floating-pointactuator technology.The heatingminimum airflow setpoint is enabledduring reheat.The water valve opens as spacetemperature drops below the heatingsetpoint. Water valve position isdependent on both the degree thatspace temperature is below the activeheating setpoint and the time that thespace temperature has been below theactive heating setpoint. If not alreadyclosed, the water valve fully closeswhen the zone temperature risesabove the active heating setpoint by0.5 F (0.28 C). An additional on/offremote heat output is available andenergized when the proportional valveis driven 100% open and de-energizedwhen the proportional valve reaches50% open. When reheat is deenergized, the cooling minimumairflow setpoint is activated.Single-Duct: On/Off ElectricReheat—Three stages of stagedelectric reheat are available. Theheating minimum airflow setpoint isenabled during reheat.Stage 1 is energized when the spacetemperature falls below the activeheating setpoint and minimum airflowrequirements are met. When the zoneDDCReheatControltemperature rises above the activeheating setpoint by 0.5 F (0.28 C),stage 1 is de-energized. Stage 2energizes when the space temperatureis 1 F (0.56 C) or more below the activeheating setpoint, and is de-energizedwhen the space temperature is 0.5 F(0.28 C) below the active heatingsetpoint. Stage 3 energizes when thezone temperature is 2 F (1.11 C) ormore below the active heatingsetpoint, and de-energizes when thespace temperature is 1.5 F (0.83 C)below the active heating setpoint.When reheat is de-energized, thecooling minimum airflow setpoint isactivated.Single-Duct: Pulse-WidthModulation of Electric Heat—Electric heat is modulated byenergizing for a portion of a threeminute time period. The heatingminimum airflow setpoint is enabledduring reheat. This allows exact loadmatching for energy efficientoperation, and optimum zonetemperature control. One or twostages can be used.The amount of reheat supplied isdependent on both the degree thatspace temperature is below the activeheating setpoint and the time that thespace temperature has been below theactive heating setpoint. If not alreadyoff, reheat de-energizes when the zonetemperature rises more than 0.5 F(0.28 C) above the heating setpoint.The Stage 1 “on” time is proportionalto the amount of reheat required. Forexample, when 50% of stage 1capacity is required, reheat is on for 90seconds and off for 90 seconds. When75% of stage 1 capacity is required,reheat is on for 135 seconds and off for45 seconds. When 100% of stage 1capacity is required, reheat is oncontinuously.Stage 2 uses the same “on” time logicas stage 1 listed above, except stage 1is always energized. For example,when 75% of unit capacity is required,stage 1 is energized continuously, andstage 2 is on for 90 seconds and off for90 seconds. When reheat is deenergized, the cooling minimumairflow setpoint is activated.VAV-PRC008-ENC5

If not alreadyclosed, the water valve fully closeswhen the zone temperature risesabove the active heating setpoint by0.5 F (0.28 C).
