The heat tracing circuit control assignments would be as follows:

Circuit No. Setting

1 thru 10 Enabled (Ambient Sensed Dual RTD’s)

11 thru 18 Enabled (Pipe Sensed Dual RTD’s)

In this case, power relays on circuits 1 thru 10 will be controlling ambient sensed cir-

cuits based on the RTD input on Circuit 1 and speciﬁcally RTD#1 and RTD#2. The

remainder of Circuits (2-10) and associated power relays will be controlling based

on the RTD inputs from Circuit 1 and will not have RTD’s populated on these circuits.

Circuit 11 thru 18 and their associated power relays will be controlling based on the

dual RTD inputs fed to each of their respective circuits.
