1 Control & Monitoring

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

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 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 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 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 7 Self-Regulating Control is Simple Power Connection Heating cableEnd Seal Distribution Panel

8 8 Ambient Sensing Control Distribution Panel Ambient sensing thermostat Main Contactor

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

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

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

12 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 13 Monitoring Using GFPD Distribution Panel Power Connection Heating cable End Seal

14 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 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 16 Temperature Monitoring w/910 DigiTrace 910 Distribution Panel W/ Standard Circuit Breaker RTD

17 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 ( ), APS-4 (277), APS-3B - Sensors - CIT-1, GIT-1, SIT-1

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

19 19 Distribution Panel w/GFPD’s Main Contactor Manual Control Simple Switch

20 20 Distribution Panel w/GFPD’s Main Contactor Ambient Control Ambient sensing thermostat single circuit control

21 21 Building Management System Distribution Panel w/GFPD’s Building Management System Main Contactor

22 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 23 Automatic Snow Controller Distribution Panel w/GFPD’s APS-3B Snow Controller Main Contactor CIT-1 pole mounted sensor SIT-1 pavement mounted sensor

24 24 IceStop Control Distribution Panel APS-4 Snow Controller Main Contactor CIT-1 pole mounted sensor GIT-1 gutter mounted sensors

25 25 Control and Monitoring For RaySol Manual or Timed Control Floor Temperature Sensing Control Floor Temperature Sensing Control and Monitoring

26 26 Manual or Timed Control Distribution Panel w/GFPD’s Simple switch or timed switch Main Contactor

27 27 Floor Temperature Sensing Control Distribution Panel w/GFPD’s Main Contactor FWT-2E Floorstat FWT-3

28 28 Floor Control and Monitoring Distribution Panel w/GFPD’s Main Contactor DigiTrace 910

29 29 Monitoring and Control for HWAT? Self-Regulating control Line Sensing Control?

30 30 HWAT Line Sensing Control? DigiTrace 910 Locate sensor on “dead-leg”
