* For two wire RTDs, install a copper sense lead of the same gauge and length as the RTD leads. Attach one end of the wire at the probe and the other end to input
common terminal. Complete lead wire compensation is obtained. This is the preferred method. If a sense wire is not used, then use a jumper. A temperature offset
error will exist. The error may be compensated by programming a temperature offset.

WIRING CONNECTIONS
All conductors should meet voltage and current ratings for each terminal. Also, cabling should conform to appropriate standards of good installation, local codes
and regulations. When wiring the controller, use the numbers on the label to identify the position number with the proper function. Strip the wire, leaving
approximately 1/4" (6 mm) of bare wire exposed. Insert the wire into the terminal, and tighten the screw until the wire is clamped tightly. (Pull wire to verify
tightness.) Each terminal can accept up to one #14 AWG (2.55 mm), two #18 AWG (1.02 mm), or four #20 AWG (0.61 mm) wires.
CONTROLLER POWER CONNECTIONS
For best results, the power should be relatively “clean” and within the
specified limits. Drawing power from heavily loaded circuits or from circuits
that also power loads that cycle on and off should be avoided. It is recommended
that power supplied to the controller be protected by a fuse or circuit breaker.
