Resistive Temperature Detectors (RTD)
Wire the two leads of the sensors to be designated
terminals in the control panel as shown below. This is
determined by the number of temperature sensors on
the job (1-10 sensors). The two wires of the sensor are
not polarity sensitive. If more than one hood is being
controlled, be sure that the appropriate sensor is wired
to the appropriate terminals as depicted on the job
specific wiring diagram.
NOTE
The RTD’s should not be exposed to direct flame. The
RTD’s are rated up to 250°F
CAUTION
Exposing the sensor to direct flame may render the
sensor inoperable and will void the warranty.
