Temperature Interlock – Digital (Optional)
Exhaust Fan Failure Indicator (Optional)
When configured with digital temperature interlock,
the KFCC will include sensor(s) (located in the hood or
EXHAUST AIR FLOW SWITCH FIELD WIRED
shipped loose) and digital controllers . Unless already
done by the factory, wire the two leads of each sensor

to the control panel as shown below using low voltage,
18 AWG stranded wire . The two wires of each sensor
are not polarity sensitive .
