Temperature Interlock, Digital; Temperature Interlock, Thermostat - Greenheck KFCC Installation, Operation And Maintenance Manual

Temperature Interlock – Digital (Optional)
When configured with digital temperature interlock,
the KFCC will include sensor(s) (located in the hood or
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.

Digital Temperature Interlock Sensors
NOTE
Do not connect temperature sensors in series.
Separate as much as possible the probe and digital
input cables from inductive loads and power cables,
to avoid any electromagnetic disturbances. Never
lay power and probe cables in the same cable
conduits (including those for the electrical panel).
Loosen every screw and insert the cable end. Next,
tighten the screws and gently pull the cables to
check their tightness.

Temperature Interlock – Thermostat (Optional)
When configured with thermostat style, temperature
interlock, the KFCC will include thermostat(s) (mounted
in hood or shipped loose) and a time delay relay. Unless
already done by the factory, wire all thermostats in
parallel back to terminal blocks T1-A and T1-B in control
panel using 14 gauge 90°C minimum conductors.
