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-Trace Freeze protection ElectroMelt, IceStop Snow and Ice Melting RaySol Floor Heating HWAT Hot Water Maintenance Self-Regulating, Line Sensing Control? Manual or Timed, Floor-Sensing Thermostat, DigiTrace910 Manual, Ambient Thermostat, Building DCS, Snow Controller Self-Regulating, Ambient & Line Sensing Thermostats, DigiTrace 910

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 Power Connection Heating cableEnd Seal Distribution Panel

8 Ambient Sensing Control Distribution Panel Ambient sensing thermostat Main Contactor

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

10 Distribution Panel Line Sensing Control Line sensing thermostat or Digitrace 910

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

12 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 Ground-Fault Monitoring

13 Monitoring Using GFPD Distribution Panel Power Connection Heating cable End Seal

14 DigiTrace 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
