Frequently Asked Questions
Regarding Temperature Interlock
What temperature is the thermostat set from the
factory?
95º Fahrenheit
How do I determine if the KFCC is configured
with thermostat style or digital style temperature
interlock?
Thermostat style interlock uses 5/8-inch diameter
probe(s) mounted in either the hood capture area or
exhaust collar(s). The KFCC will include a solid-state
relay with a 1-100 minute off-delay dial. Inspect the
probe diameter or look inside the KFCC for this solid-
state relay.
Digital style interlock uses 1/4-inch diameter probe(s)
mounted in either the hood capture area or exhaust
collar(s). The KFCC will include a controller with
a digital read out, capable of displaying different
temperature values. Inspect the probe diameter
or look inside the KFCC for this digital-displaying
controller.
Will the temperature interlock automatically start/
stop the fans?
When connected properly to the fan starters the
temperature interlock will automatically control
the fans without input from the user. However, it is
intended to be used as a back up to manual control.
With thermostat style interlock, what is the purpose
of the timer in the KFCC?
The timer is used to delay the shut down of the fans,
to prevent fan on/off cycling while the temperature
in the exhaust duct can reach steady state. Without
the delay, cycling could occur both on startup
or shutdown of cooking equipment. The delay is
typically set at 20 minutes.
How many individual breakers does the KFCC
require?
The number of individual breakers depends the
number of fans controlled and options included in
the KFCC. Each individual fan typically requires its
own breaker. The KFCC main power requires its own
breaker. Each light circuit is typically put on individual
breakers.
Can I still turn my fan on and off?
Yes, the temperature interlock is designed to operate
with a typical on/off switch. The fan may not turn off
immediately after turning the fan switch off, it will
sense when the cooking operations have cooled and
then turn off.
Maintenance
Daily
If KFCC is configured with temperature interlock,
clean thermostat or sensor with cloth and degreaser.
Keep clean for best performance. (Can clean weekly
depending upon grease accumulation).
Weekly
Depending on grease production and grease filter type
in the hood, temperature thermostats or sensors can be
cleaned weekly.
Seasonal
If KFCC is configured with temperature interlock, may
have to change temperature settings if ambient kitchen
temperatures fluctuate between summer and winter
seasons.
