Recommendations for selecting the appropriate control equipment:
Base your selection on the number and type of trace heating circuits to be installed, the type of control you need and the area classification.
TABLE K: Control Equipment Selection Recommendations

Line-sensing
on a reference pipe
PBTC-200-E (on pipe, local only) 1 per control panel
Single self-regulating heating circuit(s)
on temperature sensitive tanks
Temperature maintenance or
tight temperature control

→ Example
 The application is temperature maintain for the pipe in a hazardous area. The ambient temperature is below the maintain temperature for
only a few months every year and the customer wants to conserve energy. No remote indication or communication is required.
appropriate control equipment = PBTW-200-E
Note: Since the PBTW-200-E includes the power connection enclosure the PBS-200-E kit (from Step 11) is not required.
