  1. Control & Monitoring

  2. Control and Monitoring for the Commercial Construction Industry FWT-3

  3. Objectives • Familiarize you with the options for controlling electrical heat-tracing systems • Familiarize you with the different methods of monitoring electrical heat-tracing systems • Provide an overview of TTC’s products for control and monitoring

  4. Summary XL-TraceFreeze protection Self-Regulating, Ambient & Line Sensing Thermostats, DigiTrace 910 ElectroMelt, IceStopSnow and Ice Melting Manual, Ambient Thermostat, Building DCS, Snow Controller RaySolFloor Heating Manual or Timed, Floor-Sensing Thermostat, DigiTrace910 HWATHot Water Maintenance Self-Regulating, Line Sensing Control?

  5. Control and Monitoring are Different • Control • Varying the heating cable output to achieve the desired temperature • Monitoring • Providing feedback on the status of the heat-traced system Control Monitoring

  6. Options for XL-Trace • Self-Regulating • Ambient sensing control • Ambient sensing thermostats • Line sensing control • Line sensing thermostats • Monitoring & Control with DigiTrace 910

  7. Self-Regulating Control is Simple DistributionPanel PowerConnection Heating cable End Seal

  8. Ambient Sensing Control MainContactor Ambient sensingthermostat DistributionPanel

  9. Ambient Sensing Thermostats Fixed 40°F setpoint AMC-1A AMC-F5

  10. Line Sensing Control DistributionPanel Line sensingthermostat orDigitrace 910

  11. Line Sensing Thermostats Fixed 40°F setpoint AMC-1B AMC-F5

  12. Ground-Fault Monitoring • Advantages • Monitors integrity of heating cable and power distribution wiring • Readily available equipment • Low installed cost • Disadvantages • Monitors cable integrity, not performance • Required bell alarm contract on GFPD

  13. Monitoring Using GFPD GFPD DistributionPanel PowerConnection End Seal Heating cable

  14. DigiTrace 910 • 910 Single point electronic controller (920 Multi-point) • Approved GFPD replaces t-stat and ground fault breaker • Compatible with BMS, Networkable • Provides temperature, current and ground fault monitoring • Order RTD separately

  15. Temperature Monitoring • Advantages • Measures performance (will it freeze?) • Provides extensive alarm capability • Low and high temperature • High Low Amps • High Ground fault & Ground Fault trip • Can be networked to each other & a PC • Disadvantages • Expensive to install on each circuit

  16. Temperature Monitoring w/910 Distribution Panel W/ Standard Circuit Breaker DigiTrace 910 RTD

  17. Control for ElectroMelt and Icestop • Manual Control (on/off control switched by hand) • Ambient-sensing control • AMC-F5, AMC-1A • Automated Building Management System (on/off control switched by building computer) • Automatic snow controllers (on/off control based on temperature and moisture) • Controllers - APS-4 (208-240), APS-4 (277), APS-3B • Sensors - CIT-1, GIT-1, SIT-1

  18. Product Offering APS-4 GIT-3 APS-3B RCU-1 GIT-1 LCD-1 SC-40 CIT-1 SIT-5E

  19. Manual Control MainContactor DistributionPanel w/GFPD’s Simple Switch

  20. Ambient Control MainContactor DistributionPanel w/GFPD’s Ambient sensing thermostat single circuit control

  21. Building Management System MainContactor Building Management System DistributionPanel w/GFPD’s

  22. Automatic Snow Controller • Automatically turns on system at 38°F with the presence of moisture • Variable hold-on time after snowfall ends • Manual override • In-pavement sensor available

  23. Automatic Snow Controller MainContactor CIT-1 pole mounted sensor APS-3B Snow Controller DistributionPanel w/GFPD’s SIT-1 pavement mounted sensor
