DIGI-SPAN® TSC-Elite

Two-Stage Digital Set Point Control

 

 

Overview

 

 

The TSC-Elite Provides accurate control for two set points. The TSC-Elite is ideal whenever two stages of control are needed to maintain your set point. This applies to dual control of boilers, water heaters, fans, refrigeration units, chillers, as well as other equipment used in heating, cooling, vacuum, or humidity. It can also be used to control any 2-stage device. Finally, the TSC-Elite can control a single-stage and one alarm point. In this type of application, if the system drifts above or below a critical set point, the control will activate an alarm.

 

Heat, Cool, or Change-Over (Heat/Cool) option. One TSC-Elite provides these options using field selectable menus. Each with a set of parameters that will customized the TSC-Elite for your specific application.

 

Each TSC comes with a built-in rotation option, which allows you to rotate equipment on a 24-hour basis. This option evens out wear and tear on individual components, helping to prolong equipment life.

 

A New Continuous Operating Mode is added for the control of two units that are not equal in size. A Large unit can bring the system to the second set point. Then, a smaller unit will take over and gets the system to the first set point. In this configuration a maximum of one stage will be active at any point in time.

 

The TSC is now equipped with External Activation that allows a remote device to enable or disable the TSC-Elite operation.

 

Two Set Points. Unlike other Two-Stage Controls, the TSC-Elite has two set points to ease setting and avoid calculation errors. Each set point can be set independently from the other.

 

Can be Powered by 120VAC or 24VAC. The TSC-Elite is normally powered by 120VAC. However, it has an alternative 24VAC power input. No transformers are required.

 

English or Metric. The same TSC-Elite can be confi gured to follow either standard. Each with an array of sensor options for versatility.

 

Mounts on a 1900 Box or an Extension Skirt. The flexibility of mounting the control and the use of the supplied skirt, makes this control fit any application need and most tight spaces.

 

Sensor Fault Output Option. The TSC-Elite offers the option of switching the On or Off when a fault condition occurs.

 
 

 

  • One control can operate in two-stage heating, two-stage cooling, or Change-Over Control(COC) (Heat/Cool).
  • Built-In Enable/Disable (External Activation).
  • 24 Hour Rotation is available with a click of a button.
  • Offers a new Continuous Operating mode where only one output can be on at a time.
  • Choose the state you want your output to be on a sensor fault.
  • Mounts on a 1900 box or use the provided extension skirt for wall mounting.
  • Multi-Line Digital Display.
  • Can be powered using 120VAC or 24VAC.
  • UL Listed.

 

TSC-Elite DOES NOT COME WITH SENSORS. SENSORS MUST BE ORDERED SEPARATELY.

Why is my control not turning the boiler on even when there is a call for heat?

First, check the display for any messages as many of the heating controls have several external inputs that can be used to shutdown the boiler. If the message relates to the PROVE input, it may not be shorted or the Prove terminal Jumper is not installed. In this case, the control will not start the boiler. If the message relates to the Shutdown input, the Shutdown maybe shorted remotely. If the message relates to the T-stat input, the T-Stat input maybe opened remotely. r

My outdoor sensor reading does not match the actual temperature.

The outdoor sensor measurement may vary based on its location and its sun exposure. In most cases it will never match a weather station that is located several miles away. most current Heat-Timer controls have a Trim feature which allows the sensor reading to be slightly modified just a few degrees to satisfy similar circumstances. If the difference was large, then check the sensor by disconnecting one of its wires from the control. The control should read OPEN. If not, contact technical support.

Why is my temperature sensor reading Open on the control display?

Remove the sensor wires from the control and check for continuity across the wires with and meter. If no continuity existed, check or replace the wires. if continuity did exist, then contact technical support.

Why is my temperature sensor reading Short on the control display?

Remove one of the sensor wires from the control. The control display should change and display OPEN. Then check the sensor wiring specifically around spliced areas. If wiring was good, then disconnect the sensor wires from the control and check the sensor wires with an Ohm meter. The readings should match the sensor temperature chart on the control manual. It not, then replace the sensor. If after removing one of the sensor wires the control read SHORT, then contact tech support.
