Mounting
TheSZ1063and64aredesignedforwallmounting
usingtwo#6sheetmetalscrews,eitheroverahorizon-
tallyinstalled2"x4"junctionbox,ordirectlytoblockor
drywall.
Forbestresults,thethermostatshouldbemountedon
aninteriorwallwhichreflectsnormalroomenvironment,
ataheightofapproximatelyfivefeetfromthefloor.
Avoidareasexposedtodirectsunlight,unusualheat
orcoolsources,opendoorsandwindows,unventilated
locations and hot or cold air from diffusers.
Ifusingaremoteroomsensor,itshouldbemountedin
themannerdescribedabove.Thethermostatmaythen
bemountedinanareawhichisaccessibleforadjusting
its settings.
Caution:Removepowerfromthermostatpriorto
mounting.

Wiring
The SZ1063 and SZ1064 use standard terminal desig-
nationsfor wiring.Seediagrambelow.
REMOTE SENSOR WIRING
TheSZ1063acceptsone1000ohmtwo-wireplatinum
sensorandtheSZ1064acceptstwo.UseTS1009,
TS1002withTQSeriesImmersionwellsorTS1005for
watertemperaturesensing.
WhenusingTCS/BasysControlsthree-wiresensors,use
theblackandredleads,andeithercliportwistoffthe
whitelead.Thewiringlengthshouldnotexceed250ft.
POWERING THE SZ1064
Superstatsarepoweredfrom24VAC+/-20%.
Ifwiringforcommunications,dedicatedpowermustbe
usedtopowertheSuperstat.Several“S”Seriesther-
mostatsmaybepoweredfromthesametransformer,
providedthatthetransformerhassufficientpower.
(Superstatsrequire8VA@24VAC.)
Caution:Donotconnectto120VAC.When
multipleTCS/BasysControlsdevicesareusing
asingletransformer,thepolarityofthepower
wiringmustbemaintainedbecauseallTCS
devicesarehalf-waverectifiedandhavecom-
mon return paths.
When the Superstat is used as a stand-alone thermostat
withoutcommunications,theunittransformermaybe
usedtopowerit.Todothis,installajumperbetween
the“R”and“+24”terminals.The“24-”terminalmust
then be connected to the common side of the unit trans-
former.

Additionally,an"OverrideHold"featureisbuiltintothe
thermostats.Wheninunoccupiedmode,pressingthe
overrideonceandthenpressing/holdingitfor5seconds
putsthethermostatintoa"hold”mode(theoverrideLED
onthethermostatwillflashquicklytoconfirmthemode
change).Inthismode,theoverridesetpointsareused
untilthenextoccupiedperiodisreachedoruntilthether-
mostatismanuallytakenoutofthe"hold"modebypress-
ingtheoverridebuttonagain.Thisfeaturealsoworks
whenthe"OverrideforOccupiedPeriod"isenabledBUT
starting from the occupied mode and holding the thermo-
stat in the unoccupied state.
AcontinuousoverrideisavailablethroughtheDI3contact
orthesoftware.IfDI3issettoexternaloverride,theunit
willbeintheoccupiedmodewhenevertheDI3contactis
closed.Whenusingthisoption,thetimedoverridemay
stillbeactivated.
SETBACK AND OVERRIDE APPLICATIONS
Inmostapplications,itisdesiredtomaintainaregular
schedule,andallowtimedoverridewiththebuttononthe
faceorwitharemotemomentarycontact.
Toallowaregularschedule,andalsoautomaticallyover-
ridewiththeuseofoccupancyorlightsensor,setDI3to
overrideandsetitupsothatthecontactisclosedwhen
youwanttheoverride.
Forapplicationswherearoommightnotbeusedona
regularschedule,suchasconferencerooms,setDI3to
externaltimeclockandclosethecontactwhenyouwant
theroomoccupied,suchaswithaswitchorwind-up
timer.Ifeachoccupancyperiodisaboutthesame,(the-
aters,meetings)anotheroptionistosettheDI3toexter-
naltimeclock,andusethetimedoverridebuttontoput
the unit in occupied mode.
Tomaketheunitalwaysoccupied,setDI3toexternal
timeclockandshorttheDI3terminaltoground.
TWO-PIPE FAN COIL OPERATION
Fortwo-pipefancoiloperation,instep#28selectNO.In
step#29,selectYES.Youmustthenselectwhetherthe
systemisHEATingonly,COOLingonlyorheatingand
cooling(H&C)instep#30.
Whenusingatwo-pipesystemtodobothheatingand
cooling,theSZ1063andSZ1064needtoknowwhether
hotorcoldwaterisavailable.Thisisaccomplishedby
eithertheuseofamechanicalaquastat(bulbthermostat)
connectedtoterminalsDI1and24-,orbytheuseofa
temperaturesensorconnectedtoT2andT2(SZ1064
only).Ifusingamechanicalthermostat,selectDIGITAL
instep#31,andselectnormallyclosedN.C.ornormally
openN.O.Instep#32.Ifusingatemperaturesensor,
selectANALOGinstep#31andplaceachangeoverset-
pointinstep#33.Whenthetemperatureisgreaterthan
thissetpoint,itisassumedhotwaterisavailableand
heating is done. When the temperature is less than this
setpoint,itisassumedcoldwaterisavailableandcooling
is done.
Whenusingatwo-pipesystemtodobothheatingand
cooling,onlyAO2isused.Whenusingatwo-pipesys-
temtodoonlyheating,onlyAO1isused.Whenusinga
two-pipesystemtodoonlycooling,onlyAO2isused.
THREE-PIPE FAN COIL OPERATION
Forthree-pipefancoiloperation,instep#28selectYES.
Three-pipe fan coil operation assumes that there are
twowatersourcesavailable(hotandcold),andthat
thewatertothefancoilwillbeamixtureofthese.Only
analogoutputtwoisusedforthree-pipeoperation.The
outputwillbe12mA(4-20mA)whenthereisnoneedfor
heatingorcooling.Astherebecomesaneedforheating
orcooling,theanalogoutputmodulatestoward4mAor
20mAdependingonwhetheranalogoutputtwoisdirect
orreverseacting.
FOUR-PIPE FAN COIL OPERATION
Forfour-pipefancoiloperation,instep#28selectNO.
Instep#29,selectNO.
Four-pipefancoiloperationassumesthattherearetwo
watersourcesavailable(hotandcold),thatareeach
controlledbyitsownvalve.Analogoutputoneisused
forheatingandanalogoutputtwoisusedforcooling.
PIPE TEMPERATURE SENSING
The SZ1063 and SZ1064 accepts a remote pipe tem-
perature sensor for monitoring purposes or for change-
overinatwo-pipesystem.(Seesetupinstructionsfor
dipswitchplacementforthisoption.)
Thepipetemperaturespanis0to150°F(-17.8to
65.6°C).
ANALOG OUTPUTS
The analog outputs on the SZ1063 and SZ1064 are
used to control the heating and cooling in a space.
Analogoutput1isusedtocontrolheatingandanalog
twoisusedtocontrolcoolingwithafourpipesystem.
Onlyanalogoutput2isusedwithathree-pipeorwith
two-pipesystemsetforheatandcool(H&C).
DI2 SETPOINT SHIFT
TheSZ1063andSZ1064allowDI2tobesetforsetpoint
shiftforenergydemandsetback.Adigitalcontactthat
closeswhensetbackisneededshouldbewiredinto
DI2.Youmayspecifyanumberofdegreessuchthat,
whenthethermostatisoperatingintheoccupiedmode,
andDI2isclosed,theheatingsetpointwillbelowered
thisnumberofdegrees,andthecoolingsetpointwill

BUILT-IN DELAYS
TheSZ1063andSZ1064havedelaysbuiltintothepro-
grammingsequencestoprotectequipment.Thefanhas
a minimum on and off time of 30 seconds. When the fan
isinAUTOmode,itwillcomeon30secondsbeforethe
heatingorcoolingdevicesareallowedtosequenceon.
Theauxiliaryrelay,whensettobeastageofheator

DELAYONPOWERUP
TheSZ1063andSZ1064haveanadjustabledelayon
powerupandstart-up.Whenseveralthermostatsare
usedatonelocation,andthepowergoesout,mostther-
mostatsturnalloftheunitsbackonatthesametimeon

youtosetavalue,inseconds,wherenooutputsare
Iftheauxiliaryrelayisusedasheatingorcoolingstage,
youmayspecifyanoffsetandadifferentialvalue.The
offsetvalueistheamountawayfromthesetpointa
stagewillturnoff.Byassigningavalueotherthanzero,
you"anticipate"thattheresidualheatorcoolinginthe
ductwillbringthetemperaturebacktosetpoint.Inmost
cases,afirststageissettozero.Thedifferentialvalue
isthedifferencebetweentheonandoffpoints.Using
anoffsetvaluegreaterthanorequaltotheproportional
bandofananalogoutputwillallowtherelaytocomeon
afterfullmodulationisachieved.Stripheat,forexample.
Iftheauxiliaryrelayisusedasatimeclockoutput,itis
selectablewhethertherelayisopenorclosedduring
theoccupiedperiod.Duringtheunoccupiedperiod,the

Outputs Will Not Shut Off
Firstchecktheroomtemperatureandthesetpointsand
determinewhethertheoutputshouldbeon.Thereare
delaysandminimumonandofftimesforthefanand
heatingandcoolingstages.Also,checktheservice
statusmenustoverifythattheoutputsareon.Turning
thesystemto"off"willinstantlyturnalloutputsoff.The
thermostatcanberesetbypressingthesystemswitch
buttonandtheservicestatusbuttonsimultaneously.
Analog Output Not Working Properly
Checkwiring.Aseparatetransformershouldbeusedfor
theSZ1063andSZ1064,andaseparatetransformer
shouldbeusedforthemotor(s).Checktomakesure
thattheanalogoutputisprogrammedcorrectly.
ChecktheMonitoringscreens.TheModOutScreens
willtellyouwhattheSZ1063andSZ1064istryingtoput
out.Comparethiswiththeactualpositionontheheating
orcoolingdevice.
Output Operation is not Correct
Checkprogrammedparameters,inparticular"Reverse"
and"Direct"actingselectionsand"Heat"or"Cool"
selectionsfortheanalogoutputs,and"Offset"and
"Differential"selectionsand"DelayTimes"fortherelay
outputs.Checkwiring.
