3TSC Digi-Elite Operation Manual
Installing and Wiring Temperature Sensor Inputs
(T1, COM (-30°F-250°F)
A variety of sensor inputs can be connected to the TSC-Elite series depending on the model and
sensors provided. Each TSC-Elite comes with the sensors it is designed to work with.
• Thesensorwirescanbeextendedupto500'bysplicingwith18gaugeshieldedwire.
• Donotrunsensorwiresinconduitwithlinevoltage.
• Ifmeasuringliquidtemperature,thesensorshouldbeinsertedintoa3/8"IDwell
(HT#904011orequivalent).
• TheTSC-Elitewilloperatebasedonthetemperatureitreadsatthesensorlocation.

7TSC Digi-Elite Operation Manual
• Incoolingapplications,theTSCElitecontrolwillusetheSetPointplustheDifferentialasastarting
point when sensor reading is increasing. It will energize the output relay as long as the sensor is
above the Set Point (Target).
• Whenthesystemvaluefallsincoolingapplications,therelaywillremainenergizeduntiltheSet
Point (Target) is reached. Then, it will de-energize.
• TheChange-OveroptionwillallowOutput1relaytofollowSP1.Output1relaywillenergize
wheneverthesensorvalveisaboveSP1plusthedifferential.Therelaywillde-energizewhen
thesensorvaluedropstotheSP1value.TheOutput2relaywillfollowSP2.Output2relaywill
energizewheneverthesensorvalveisbelowSP2minusthedifferential.Therelaywillde-energize
whenthesensorvalueincreasestotheSP2value.
Output Light
The TSC Elite has three lights, however, only the left two output
lights are used. They follow the relay operation. Whenever,
theleftOutputLightisON,Output1isactiveandtherelayis
energized.ThemiddlelightwillrepresentOutput2status.
Enable/Disable Input
TheTSCElitewilloperateinheatingorcoolingmodesonlyiftheEXT-andEXT+terminals
are shorted. If no external equipment or switch is connected to these terminals, leave the factory
installedjumper.WhentheterminalsareOPEN,theTargetwilldisplayTSTATOPEN.
ALERT
On a sensor fault while the Enable/Disable terminals are open, the
control will follow the Enable /Disable state. However, the System
Sensor will display the fault condition weather Short or Open.

Troubleshoot
No Display:
 Turnthepoweroffandbackon.MakesuretheDisplaysection
is mounted securely to the base.
OPEN or SHORT Display:
 First,makesurethattheSensorTypeselectedmatchesthe
sensor used. Also, make sure that the sensor is connected to
therespectiveinputterminals.IfcontrolreadsOPEN,the
TSC-Elite either does not see a sensor connected or the sensor
reading is below the sensor operating range. Check the sensor
wires are connected from the sensor to the TSC-Elite controller.
If SHORT, the TSC-Elite either sees a short across the input
terminals or the sensor reading is above its operating range.
Remove the sensor wires from the TSC-Elite terminals, the
displayshouldreadOPEN.Ifthedisplaydoesnotchangeto
OPEN,theTSC-Elitemaybedamaged.Otherwise,followsteps
for Incorrect Temperature Display for temperature sensors or
IncorrectpressureorVacuumDisplayforalltransducers.
Incorrect Temperature Display:
 RemovethewiresfromtheSENSORscrews.Thedisplay
shouldchangetoreadOPEN.Ifitdoesn’t,theTSC-Elitemay
bedamaged.Fortemperature,takeanohmreadingacrossthe
detached sensor wires. The ohm reading should correspond
tothechartontheright.Iftheohmreadingissignicantly
different, the sensor may be damaged.

Incorrect Pressure or Vacuum Display:
 Makesurethatthepressuresettingselectedmatchesthepressure
transducer connected to the TSC-Elite control. If it does, then use a
current multi-meter and set it to read mA and put it in series with the
sensor.Matchtheohmreadingtothepressuretablebelow.Ifcurrent
does not match the actual pressure, use the System Trim from the
MaintenanceMenutocorrectit.Ifthedifferenceislargerthanthe
System Trim range, then the pressure or vacuum transducer is damaged.
RememberthatPressureandVacuumtransducersaresusceptibletostatic
electricity. Thus, reduce excessive manual handling prior to transducer
installation.
Output Red Light does not come on at the desired temperature:
Check the set points and differential values. In a heating application,
the Red light will not come on until the sensor value drops below the
set point minus the differential. In a cooling application, the Red light
will not turn off until the sensor value rises above the set point plus the
differential.
TSC-Elite does not activate the output:
 FirstremoveallconnectionstotheWhiteandBlueoutputwires.Ifboth
Outputs'RedLightsareon,therelaysshouldbeenergized.Boththe
WhitewiresandtheBluewiresshouldbeclosed.IfbothOutputs'Red
Lightsareoff,therelaysshouldbede-energized.BoththeWhitewires
andtheBluewiresshouldbeopen.Iftheabovetwoconditionsaremet,
the TSC-Elite is working normally. Check the unit the TSC-Elite is
controlling.
