General Description
Receiving and Handling
Description
The kitchen fan control center, or KFCC, is a pre-engineered package designed to control the operation of fans in a constant-volume kitchen. The package consists of a cabinet encasing one or more fan motor starters interlocked together for on/off operation. Different fan, light and thermal switch combinations may be provided to operate the kitchen hood fan(s), light(s), and heating/cooling capabilities of the supply air. The control center as a standard is equipped with additional relays prewired to the fan starter(s). These additional relays are capable of turning on the kitchen exhaust and shutting down supply regardless of the present state of the fans via integration of a fire system microswitch with factory terminals. The control center can be equipped with temperature interlock, designed to automatically start kitchen fans and keep them running while heat is being generated from the cooking appliances. Hood systems should always be manually started before the cooking equipment is turned on, but if forgotten the interlock will safely trigger the fans to start once heat is detected. Other options are available.
Purpose
The purpose of the KFCC is to provide a complete control center to provide and house all fan starters. The control center provides a common connection point to interlock kitchen exhaust, supply, and hood lights with the hood’s fire suppression system. The cabinet is pre-engineered with terminal blocks for most field wiring connections. The control center can also be equipped with interlock between the exhaust fans and cooking equipment, as to meet International Mechanical Code (IMC) 2006 section 507.2.1.1. In this case, the system will utilize a temperature sensor in the exhaust duct collar or capture area in the hood to detect heat generated from cooking operations and automatically activate the exhaust fans if not already running.
Product Application
The KFCC is designed for both Type I and Type II (grease and non-grease) constant-volume hood systems, where starters are needed to activate fans. The control center can operate both single and three phase fans. Greenheck recommends using one KFCC per hood system (activates all fans simultaneously). When temperature interlock is provided in this package, it is not to be used in conjunction with exhaust fire dampers.
Receiving
Upon receiving the product, check to make sure all items are accounted for by referencing the bill of lading to ensure all items were received. Notify the carrier if any damage is noticed. The carrier will make notification on the delivery receipt acknowledging any damage to the product. All damage should be noted on all of the copies of the bill of lading which is countersigned by the delivering carrier. If damaged upon arrival, file a claim with the carrier. Any physical damage to the unit after acceptance is not the responsibility of the manufacturer.
Unpacking
Verify that all required parts and the correct quantity of each item have been received. If any items are missing, report shortages to your local representative to arrange for obtaining missing parts.
Storage
If a kitchen fan control center must be stored prior to installation, it must be protected from dirt and moisture. Indoor storage is highly recommended. For outdoor storage, cover the control package with a tarp to keep it clean, dry, and protected from UV (ultraviolet) radiation damage.
NOTE
Improper storage which results in damage to the unit will void the warranty.
Handling
Make sure the equipment does not suffer any heavy vibration or knocks.

Fire System Integration
A dedicated fire system microswitch needs to be wired into the KFCC. During a fire, this will disengage supply starters, and therefore turn off corresponding supply fans. If KFCC is configured with “Exhaust in Fire” option, the KFCC will also engage the exhaust starters, therefore turning on exhaust fans in the event of a fire.
Dedicated Fire System Microswitch
• Common to terminal C1
• Normally-closed to terminal NC1
• Normally-open to terminal NO1

Temperature Interlock – Digital (Optional)
When configured with digital temperature interlock, the KFCC will include RTD sensors and digital controllers. Wiring from terminal blocks to controllers will be done in the factory. Use two 18 AWG stranded thermostat wires from each temperature sensor to the appropriate terminal blocks in the KFCC. (See the table below for connection options). In temperature sensor junction box, connect leads on RTD to the 18 AWG conductors using appropriate size wire nuts. These conductors for each sensor are not polarity sensitive.
RTD Sensors
Choose the final connection option based on the table.
Temperature Interlock – Thermostat (Optional)
When configured with thermostat style, temperature interlock, the KFCC will include thermostat(s) and a time delay relay. Wiring from terminal blocks to the time delay relay will be done in the factory. Use two 14 AWG 90°C minimum conductors from each thermostat to the appropriate terminal blocks in the KFCC. In the thermostat junction box, connect leads on the thermostat to the 14 AWG conductors using appropriate size wire nuts. These conductors for each thermostat are not polarity sensitive.

Digital Style Temperature Interlock Configuration
NOTE
This section only applicable if the KFCC is configured with digital temperature interlock option.
Calibration
The temperature controller is preset by the factory to turn the fans on at 95°F. This is controlled by the set point on the temperature controller. The temperature set point may have to be adjusted slightly depending on both ambient and cooking conditions. The adjustment is made through the buttons on the temperature controller. The controller is capable of monitoring two separate sensors. If more than one sensor is utilized with a single controller, two set points can be adjusted. To adjust, follow these instructions:
1. If setting set point 1 (St1), press Set. The display shows St1 and then the current value of St1.
If setting set point 2 (St2), press Set twice, slowly.
The display shows St2 and then the current value of St2.
2. Press the S or T to change the set point.
3. Press Set to confirm the new value of either St1 or St2.
4. Check system operation before making additional adjustments.
Factory Selected Parameters
The factory will pre-program the controllers to be properly integrated into the control panel. Except for the set points, the other parameters shouldn’t need adjusting. However, there are three different types of parameters that are accessible on the controller. Access differs depending on the type: set point; frequently used parameters (P); and configuration parameters (c, d, F).
NOTE
The controller is pre-programed at the factory to operate with the digital temperature interlock components. No further parameter changes should be necessary.

Testing
1. Turn the fan switch(es) on, then off to ensure proper fan operation before cooking equipment is started. Once this is verified, testing can proceed.
2. If applicable, turn the light switch(es) on, then off to ensure proper light operation in the hood. Once this is verified, testing can proceed.
3. Press and hold down the fire suppression switch connected to the KFCC and verify that the corresponding exhaust and/or supply fan(s) react appropriately when in the fire state. Verify all shunt trip breakers, alarms, and other components utilizing any of the spare relay contacts in the KFCC are activated properly.
4. If the KFCC is configured with thermostat style
temperature interlock, please follow steps 5 through 9 below. If the KFCC is configured with digital temperature interlock, please follow steps 10 through 12.
5. For testing only, locate the time delay relay. Turn the time adjustment knob counterclockwise to the first mark in order to expedite the testing process. Make a note as to where the timer was originally set.
6. Heat up cooking equipment with fans off. Once the temperature reaches the set point of the thermostat the fans will start, preferably within 5 minutes. If the fans take more than 5 minutes to start, decrease the temperature set point by turning the adjustment screw 1/16 turn clockwise. Do not apply direct flame to the thermostat.
7. If an adjustment was made in Step 6, repeat now.
8. After verification of fan start-up, shut down cooking equipment. The fan switch should still be in the off position. Once cooking equipment has cooled, the thermostat will open triggering the timer to begin. Once time has expired, the fans will shut down. Thermostat operation can be verified by checking voltage (120 VAC) between T1-B and neutral on the KFCC. 120 VAC will be present when the thermostat senses heat.
9. Once proper operation has been verified, set the dial on the timer relay to its original setting (approximately 20 minute delay).
10. Heat up cooking equipment with fans off. Once the temperature reaches the set point +5°F. the fans will start. If the fans take more than 5 minutes to start, decrease the temperature set point by adjusting the set point on the temperature controller (see Calibration).
11. If an adjustment was made in Step 10, repeat now.
12. After verification of fan start-up, shut down cooking equipment. The fan switch should still be in the off position. Once cooking equipment has cooled below the set point and the fans have been on for a minimum of 5 minutes, the fans will shut down.
CAUTION
Both the RTD sensors and the thermostat probes provided in temperature interlock options should never be exposed to direct flame. EXPOSING THE
SENSOR TO DIRECT FLAME MAY RENDER THE SENSOR INOPERABLE AND WILL VOID THE WARRANTY.
NOTE
If the KFCC was configured with temperature interlock and during testing the fans do not start automatically in the first 10 minutes of cooking equipment activation, manually start fans to avoid accidental fire system dump due to heat build-up.

Operation
Troubleshooting
1. Turn fans on and off using the fan switch.
2. If KFCC is configured to control hood lights, turn
hood lights on and off using the light switch.
3. If KFCC is configured with digital style
temperature interlock, it is normal for the fan(s) to remain running after the switch is turned off. The exhaust temperature controller(s) contacts will open after heat is no longer present underneath the hood(s), the temperature is below the set point and the fan(s) have at least been running for 5 minutes. When the controller contacts opens, the fan(s) shall shut down. In the event that the cooking equipment is started without turning the fan(s) on manually, the fan(s) will turn on automatically and remain running with the presence of heat under the hood. The temperature plus a 5°F hysteresis in order to turn on. Once the temperature is below the set point and the fan(s) have at least been running for 5 minutes, the fan(s) will shut down.
4. If KFCC is configured with thermostat style
temperature interlock, it is normal for the fan(s) to remain running after the fan switch is turned off. The exhaust thermostat(s) will open after heat is no longer present under the hood, which will activate the timer to begin its countdown. Once the time has expired, fan(s) will shut down. The timer is adjustable from 1-100 minutes. The recommended time delay setting is approximately 20 minutes. In the event that the cooking equipment is started without turning the fan(s) on manually, the fan(s) will turn on automatically and remain running with the presence of heat underneath the hood. The exhaust thermostat(s) will open after heat is no longer present under the hood, which will activate the timer to begin its countdown. Once time has expired, fan(s) will shut down.
1. Fan(s) do not turn on automatically upon cooking equipment activation
• Confirm that the KFCC has been configured with temperature interlock, either thermostat style or digital style.
• Check wiring to control panel. With thermostat style interlock, thermostats must be wired in parallel. With digital style interlock, sensors must be wired to the control panel separately.
• Temperature set point is too high, decrease set point.
• No power to fan(s), check breakers/starters/relays.
2. Controller(s) in KFCC display E01 or E02 and
fan(s) will not shut off.
• E01 and E02 represent sensor faults.
• Check wiring connections between the sensor and control cabinet.
• Check probe resistance between the two leads coming off the sensor when disconnected from the system. At room temperature (77°F) the probe will read approximately 1025 ohms.
3. Fan(s) do not shut off.
• Manual fan switch must be in the off position.
• If the KFCC is configured with digital style temperature interlock, check the controller to determine if there is a probe error of E01 or E02. If yes, refer to the controller display error message, item2 above.
• Cooking equipment is still hot, and the KFCC is configured with temperature interlock. Wait for the equipment to cool.
• Temperature set point for temperature interlock is set too low; increase set point.
• Ensure wires are connected to appropriate control circuit.
4. Exhaust fan(s) will not shut off, and supply fan(s)
will not turn on.
• Check hood for fire system dump.
• If no fire system dump has occurred, check fire system wiring between fire system microswitch and control panel.
5. Fan(s) do not turn on quick enough.
• Decrease temperature set point

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).
Frequently Asked Questions Regarding Temperature Interlock
What temperature is the thermostat set from the factory?
95º Fahrenheit
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.
Whom to call
Contact your local manufacturer’s representative.
What to have ready for the call
Sales order, serial number and description of product. Sales Order Number ________________________ Serial Number ______________________________
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 solid­state 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.
