2.1 Steps to Set Up Static Pressure Control

1. Ifthecontrollerisoperatingabuildingthatutilizestunnelventilation,youmustfirstdeterminewhetheryou

wouldliketouseaseparatetargetstaticpressurewhiletunnelventilating.Ifso,youmustgotothe“Tunnel

3. ThelaststepistosetupyourStaticPressureRampingthatwillbeusedduringallotherformsofventilation

otherthantunnelventilation(unlessyouselected“No”inStep1).Ofcourse,ifyoudonotelecttousestatic

pressureramping,thenthemanualsettingislocatedonthe“TargetConditions”screen.

StaticpressurerampingisanEvolutionfeaturethatispatentedandnotavailableonothercontrollers.This

featureallowsausertosetdifferenttargetstaticpressuresfortheirbuildingbasedontemperature

differencesbetweentheoutsideandinsidetemperatures.Itinsuresthathighertargetpressuresareused

3. Utilizing Vent Anticipation

VentAnticipationisafeatureoftheEvolutioncontrollersthatisusedduringminimumventilation.Duringminimum

ventilation,yourfansareoperatingonatimerthereforethereareperiodsoftimewhiletherearenofansoperating.

Whenyourfansareoff,yourinletsystemsarecompletelyclosed.Whenthefanturnson,ittakesacertainamountof

timefortheinlettoopen.Duringthistime,thebuildingwillseehighstaticpressures.Thisputsextraloadonthefans

andcausesthebuildingtospendmuchofitstimercyclenotgettingthefullbenefitsofitsventilation.Vent

anticipationallowstheusertosetthecontrollertoanticipatethetimercycleandpreparetheinletsystemtogetinto

positionbeforetheventilationcyclebegins.Thesesettingsarelocatedonthe“StaticPressure”screenwhichisshown

below.



IfyouwouldliketoutilizeVentAnticipation,youmustfirstenableitbyturningitto“On”.Youmustthendetermine

whetheryouwantthecontrollerto“LearnTimes”.Thissettingallowsthecontrollertoselectandconstantlyupdate

your“Pre”and“Post”anticipationtimes.Thisisnotrecommendedforpeoplewhoutilizeavariabletimerorthe

optimummode.Ifyouset“LearnTimes”to“No”,theusercanmanuallysetthe“Pre”and“Post”anticipationtimes.It

isafairlyeasyprocessbutyoumustfirstunderstandthedifferencebetween“Pre”and“Post”settings.“Pre”indicates

theamountoftimeinsecondspriortothefanturningonwhenyourinletsystemshouldstartmoving.Everyfanhasa

“start‐up”time.Thisistheamountoftimeittakesforyourfantogofromstarttofullspeed.Thisisyour“Post”time.

Typically,thistimeisunder5seconds.

Tomanuallysetyour“Pre”and“Post”times,firstyoumustdetermineabouthowlong,inseconds,ittakesyourinlet

systemtoopenwhenyourminimumventilationfansturnon.Thenyoumustdeterminethe“start‐up”timeofyour

your“start‐up”time.Itisimportanttonotethatifyouadd,orremove,fansfromyourminimumventilationyourtotal

inletruntimewillchangebutyour“Post”timewilltypicallybethesamesoadjustmentswillonlybemadetothe“Pre”

time.The“Pre”timeshouldbealinearrelationshipwiththenumberoffansthatyouareusing.Forexample,ifyou

beginwithtwo36”fansforminimumventilationandittakes10seconds“Pre”timeand4seconds“Post”timeforthe

4. Managing Inlet Levels

TheEvolutioncontrollerestablishesinletlevelsbasedonthewaythatyousetthecontrollerup.Thedefaultinlet

systemistheSidewallinletandtheTunnelinlet.Theseinletswillbecalleduponwhenneedednomatterhowtheuser

hasset‐upthecontroller.Therearetwootheroptionalinletsystems.OneisAtticinletsthatareusedmostlyduring

minimumventilationbutcanalsobeusedduringpowerventilation.Theotherisasecondtunnelinletcalled“Tunnel

Inlet2”.Iftheuserwantstoutilizeoneorbothoftheseunits,theymustenabletheminsoftware.Thetwoscreens

shownbelowarethe“TunnelSetup”screenwhereyoucanenable“TunnelInlet2”andthe“StaticPressure”screen

whereyoucanenablethe“AtticInlets”.Itisveryimportanttoproperlysetthesesothatthecontrollerrealizeswhat

inletresourcesthatithasavailable.

Forthesakeofthisdiscussion,let’sassumethatallfourpossibleinletsystemsareavailabletobeused.Thatgivesthe

controllerfourdifferentinletsystemswhichare:

• AtticInlets

• SidewallInlets

• TunnelInlet1

• TunnelInlet2

JustbecauseAtticInletsareenableddoesnotmeanthattheyareavailableforuseatalltimes.Therearetimeswhen

theheatedairintheatticwillbedetrimentaltowhatyouaretryingtoaccomplishinthebuilding.TheEvolution

controllerrecognizesthisandbasedonmanyfactors,itmakesadeterminationofwhethertheyareusedornot.This

willbediscussedfurtherinthenextsection.Also,duringtunnelventilation,onlyTunnelInlet1andTunnelInlet2are

used,theAtticandSidewallinletsareclosed.

Part No. 4809-0011 Rev 01-10 EV Attic Inlets Page 8 of 14

Duringallmodesofventilation,excepttunnelventilation,thecontrollerisallowedtoutilizeallenabledlevelsofinlets

whichinthiscasewouldbeallfour.Inotherwords,intheeventofaninletfailureorifthecurrentinletlevel’scapacity

isexceeded,thecontrollerwillrecognizethisandmovetothenextavailableinletsystem.Itmakesthisdetermination

bymonitoringchangesinthestaticpressureversustheactionoftheinletsystem.Thisisnotonlytrueasventilation

increasesbutalsoasventilationdecreases.Ifnecessary,thiscontrolleriscapableofshiftingthroughallfourinlet

systemsinsideoffiveminutes.

ThisisanimportantfeatureoftheEvolutioncontrollerformanyreasonsbutthemostimportantissafety.Let’sfaceit,

inletsystemsfailfromtimetotimeandusersmakeerrorsfromtimetotime.Withthiscontroller,ifeitherofthese

happens,thebuildingwillstillbesafelyventilatedaslongasoneofthefourinletsystemsisavailableandoperational.

Forexample,iftheuserdecideshedoesn’twanttoutilizeAtticInletssohemanuallydisablesthemwiththeoverride

switch,thecontrollerwillrecognizethisandmovetotheSidewallInlets.IftheSidewallInletsaremaxedout,the

controllerwillrecognizethisandallowTunnelInlet1tocracktorelievethepressure.Lookingatyour“Stage

Conditions”screenyoumightseethefollowing.

Asyoucansee,eachinletstagewillcomeasasetwiththeoddstagenumberalwaysbeingthe“Open”outputandthe

evenstagealwaysbeingthe“Close”output.Payparticularattentiontothestatusthatisindicatedinthebrackets

besidetheinletstages.Theseareanindicationofthecurrentinletlevelstate.Theword“Disabled”willbedisplayedif

theinletisdisabledeitherbydisablingitintheprogramsetupor,inthecaseofatticinlets,thecontrollercan

determinethattheinletsneedtobedisabledduetooverheatingofthebuilding.ThiswillonlyapplytotheAtticand

Tunnel2inlets.TheSidewallandTunnel1inletsarealwaysenabledforoperation.

Ifyouseetheword“Active”,itindicatesthatthisisthecurrentinletlevelthatisbeingusedtomaintainthestatic

5. Attic Inlet Operation

Thenewestventilationtechniquebeingusedintheindustrytodaycentersaroundutilizingthesolarheatgaininthe

therearevaryingopinionsastohowtocontrolthismethodofventilation.

Intheearlystagesofatticinletventilation,itwasquicklydiscoveredthatatticventilationcanbeharmfultothe

overrideuseoftheatticinletsoncethetemperatureexceededacertainlevel.But,theuseofanatticsensorleadsto

itsownsetofissues.Rememberthegoalisnotonlytoutilizetheheattoreducegasconsumptionbuttoalsoincrease

theventilationlevelswhenwecan.Useofanatticsensorasthemaincontrolfeedbackledtoclosingtheatticinlets

prematurely.Itisalsoanunstablereadingbecausethetemperatureintheatticwillchangedependingontheamount

ofairthatyouareexhaustingthroughit.

Therefore,whenwesetouttoprovideasolutionfortheEvolutioncontrollers,wewantedtofindabetterwaytoutilize

theatticinlets.Awaythatwouldnotonlyhelpreducegasconsumptionbutwouldalsocreatewindowsofopportunity

whereifconditionswererightthecontrollerwouldactuallyoverventilatethebuildinginanefforttoimprovetheair

anderrormethodstodeterminehowtosetuphiscontrollertoproperlyoperatetheinlets.

Tocreateacontrolalgorithmthatworks,youneedtofirstfullyunderstandthegoalsthatyouaretryingtoaccomplish

andthencreateabalancebetweentheprosandconsthatexist.Inthiscasethegoalsaretoutilizethesolarheatgain
