Illustrate:

1. The terminals of Pow and Com are the power supply When using 24Vdc input, please note that the Pow connects to anode(“+”),the Com connects to the cathode (“-”)(The device is reverse voltage protected and will not work if connected backwards): when using 24V AC input, don't need to consider the anode and cathode too much, but the consideration of the code for electrical deign and installation, advice that the Pow connect the HOT and the Com connect to the NEUTRAL.

2.“Rt”is the terminal of the temperature resistance signal out, when measuring the temperature, the sensor option output is on the two terminals marked “Rt”and “T”.
